Symptom expression in cold orchard locations - Waikato observation report
25 September 2014

Orchard sites that experienced colder autumn and winter periods are reporting a higher incidence of Psa-V symptoms this spring.

Wanganui, Waikato, and Waihi sites, which experienced frosts shortly after harvest and also had a number of frost events with temperatures below zero for extended periods, are reporting increased levels of symptoms in Hayward males including Chieftan.

Late growth which was not fully mature, or growth that was damaged through autumn storms, is showing higher incidence of secondary symptoms.

Growers are recommended to particularly focus on colder areas of their orchard when monitoring to determine individual orchard impacts.

Future pollination supplies
25 September 2014

This week KVH held a meeting with pollen providers. Available pollen across the industry is around 50 percent lower than last year (which was not a good year for pollen). This could potentially cause problems with supply for 2014 if male vines are compromised due to Psa-V infection.

Growers are urged to have their early male flowers picked for pollen and if possible, support pollen providers by supplying flowers and labour. Contact your local pollen provider if you are able to help the industry build up supplies. Click here for a list of registered pollen providers on the KVH website.

All those intending to operate a pollen mill this season are required to register with KVH here.

Industry Operational Working Group for Fruit Fly Preparedness
25 September 2014

As advised in the KVH Bulletin (24 April), the Plant Market Access Council (PMAC) including Zespri and KVH have been working on a project which aims to pre-emptively agree market access conditions with key markets in the event of future incursions of significant fruit fly species in New Zealand.

The project includes developing protocols which demonstrate how New Zealand will manage a fruit fly incursion and how exporters will therefore be able to reliably export fruit fly free product minimising any trade disruptions.

For trading partners to agree to these protocols, which if a breeding population of fruit fly is found would be based on cold disinfestation of fruit, the industry must be able to demonstrate their own procedures for implementing any agreed protocols.

Therefore, ISG has recently agreed to establish a small industry working group to identify and address associated operational issues.

The objectives for this working group will be to:

  • Identify the key issues and the range of possible scenarios that need to be considered and planned for depending on what the nature of the fruit fly outbreak is, and what time of year it happens in.
  • Develop a set of guidelines to assist individual post-harvest operators to develop their own documented quality management plan for approval by MPI should cold disinfestation of fruit be required by our markets.
  • Discuss the guidelines with MPI for comment and agreement prior to publishing these to the wider industry.

It is essential for our industry to plan for what would need to be implemented, often at very short notice, in order to minimise market disruptions.

It’s important to note that while MPI are beginning the negotiations, it will likely take years for some countries to agree to these protocols.

Canker management
18 September 2014

KVH has recently received a number of reports of red exudate appearing, particularly in male vines. Best practice advice is to determine the level of infection in each block by monitoring and recording the number of plants infected and the severity of infection.

If cankers are isolated, such as at the ends of canes or leaders, consider removing them. For cankers that cannot be easily removed, excision or cauterisation may be an option. Note—research has shown cauterisation is less successful at slowing canker spread than total removal.

Growers with more susceptible male varieties should consider their options now to graft some, or all, of their male vines over to another variety in the upcoming November grafting window. It is also important to consider the potential impact on pollination, and plan now to ensure artificial pollen can be procured. Above all else, it is important to have a plan in place to determine how cankers will be managed, and the process that will be followed moving forward.

Proactive early spray programmes key to Psa-V control
18 September 2014

A focus on spraying at regular intervals from budbreak onwards will provide ongoing protection of expanding leaves and shoots. Leaves in the first week of emergence and up to three weeks old are most vulnerable to Psa-V infection.

‘Pulses’ of leaf infection observed in previous years may have been due to high numbers of leaves at this vulnerable stage not being suitably protected through significant infection events. 

Psa-V inoculum on the edges of leaf spots can reactivate in suitable weather conditions and add to the inoculum load within the canopy. This increases the risk of flower bud infection across the spring period. Hayward and Green14 can be particularly vulnerable to this infection.

A full winter rate copper with a spreader applied immediately prior to budburst is highly recommended to protect breaking buds on all varieties.
A following regular programme of coppers, Actigard™ and, in high-risk situations, KeyStrepto™, should be applied through to flowering.

Ambitious may also help reduce leaf spot and may be applied once there is sufficient leaf in the canopy (see photo). Similarly, Actigard™ also requires sufficient leaf cover at time of application to ensure uptake is sufficient to fully activate the vine. Manufacturer recommendation is to apply Actigard™ two to three weeks after bud burst, when leaf diameter is approximately 25mm.

Many Hort16A canopies will already have sufficient leaf for application of these products. AI nozzles and drift-reducing adjuvants must be used until canopy closure to minimise spray drift.  Excellent spray coverage will optimise product efficiency. Use of wetter papers is recommended to check applications.

Plant Health Australia visits Te Puke
18 September 2014

Plant Health Australia (PHA), the industry body that coordinates the government-industry partnership for plant biosecurity in Australia, visited KVH yesterday to learn about our Psa-V management approach, and to share information about future biosecurity priorities.

The full Board of Directors participated in the visit and were extremely impressed with what the NZ kiwifruit industry has accomplished in just under four years since Psa-V arrived, in terms of managing and reducing the risks using the NPMP, and also the major R&D efforts that have been achieved.

Discussions on future biosecurity priorities included understanding the Australian approach to cost sharing for fruit fly, where the arrangement in place has government funding 80 percent and industry 20 percent of the costs associated with responses.

Trichoderma product available
18 September 2014

As advised in the KVH Bulletin (15 May) Lincoln University is manufacturing a prototype trichoderma product called Trimix 1. Trichoderma are fungi present in soils, and some strains are able to colonise the root system of plants resulting in beneficial effects to the plant.

Trimix 1 is available once again to growers for use as a plant health enhancer (bio-fertiliser) from Lincoln University.They also recently received BioGro approval for TriMix-1 so it can now be used without restriction by organic growers.

While there is experimental evidence that the TriMix 1 can improve plant growth, Lincoln and/or KVH and Zespri cannot promote the product for Psa-V control as it does not have ACVM label claim from the Ministry for Primary Industries (MPI).

Growers interested in using the product as a plant health enhancer (bio-fertiliser) can click here to email Lincoln University.

Coromandel update
18 September 2014

A KVH meeting in Coromandel on Tuesday was well-attended by local growers. Psa-V expression in the region has increased significantly over the last month.

The region has experienced a cooler and wetter winter than previous years which is seen as a major contributor to the increased levels of Psa-V.
Some orchards that suffered frost shortly after harvest did not have an opportunity to apply an autumn Actigard™. These orchards are showing considerably more Psa-V than those in the same area who did manage to apply Actigard™. 

A number of Hort16A orchards showing increased symptoms are being actively monitored with regular cut-out to remove Psa-V and growers have applied KeyStrepto™.  All but one remaining Hort16A orchard are now notch-grafted and growers are looking to remove susceptible male vines following flowering.

Hayward and Green14 in the region are showing few symptoms at this early stage. The Gold3 grafted in 2012 is generally looking good. However, 2013-grafted Gold3 is showing increasing symptoms with a number of orchards cutting out infected areas.

While in the region KVH also visited a Psa-V positive Hort16A Coromandel orchard.

KVH male monitoring reports
18 September 2014

Over the last two weeks KVH has monitored four orchards with Chieftan males as part of an ongoing monitoring programme that has been running for the past two years. Two of the orchards are located in high altitude Te Puke, and the other two in Waihi.

All four orchards showed more secondary Psa-V symptoms during this monitoring round than observed at the same time last year. This is consistent with reports received from growers and postharvest over the last two weeks.

Levels of symptoms were higher in Waihi than Te Puke. After reviewing weather data it appears temperatures went below 0°C during nine days in Waihi; and on one day in Te Puke. This occurred between 1 June and 31 August. Both regions had a heavy rainfall event on 19-20August (30mm in Waihi and 19mm Te Puke).

Review of NZ import requirements for kiwifruit pollen
11 September 2014

As advised in the KVH Bulletin (31 July) MPI is carrying out two separate processes regarding pollen imports. One is reviewing the import health standard (IHS) for pollen for artificial pollination.

The importation of pollen into New Zealand remains prohibited as the potential risk of introducing further variants of Psa-V and other pathogens is still unknown.

So far advice has been received from a Technical Working Group made up of experts from the kiwifruit, bee and pollen industries. MPI has drafted an assessment of the potential for Psa to be associated with imported pollen. Other pathogens which may also be associated with imported pollen, and which may impact on the kiwifruit or bee industries have been identified by MPI, but have not yet been assessed.

MPI will provide an update on the assessment process by the end of September.

However, MPI has advised it’s unlikely the current prohibition on importing pollen for pollination will be lifted prior to this pollination season, if at all.
Therefore KVH’s earlier advice to growers for future pollination requirements stands:

  • Manage your male vines—develop low-vigour growing systems
  • Assess the health of your male vines—diseased males can impact future pollination requirements
  • Detecting diseased males early will allow time to assess your future pollination requirements
  • If males need to be cut out, ensure you have a plan for future pollination requirements
  • Order pollen early from KVH-registered pollen providers for future pollination requirements
  • Arrange harvest of early flowers for pollen milling wherever possible
  • Store pollen for next season wherever possible
  • Graft to more Psa-tolerant varieties

KVH attends GIA forum
11 September 2014

Last week KVH’s Chief Executive Barry O’Neil and Biosecurity Programmes Manager Andrew Harrison attended the Government Industry Agreement (GIA) Biosecurity Forum in Auckland. More than 40 of the 75 attendees were representing primary industry, including many of horticulture’s product groups.

The purpose of the forum is for all GIA signatories to share their understanding of biosecurity; and work together to enhance the system for all, as opposed to bilateral or multilateral collaboration on organism-specific readiness and response activities that will be achieved through Operational Agreements.

Last week’s meeting included an introduction to GIA, an information session on Import Health Standards and a site visit to biosecurity facilities around Auckland Airport.

Key discussion points from the Forum:

  • Two industries have now signed the GIA Deed (kiwifruit and pork) and a number of other groups are expected to sign in the near future.
  • Managing incursion responses under GIA, including rapid industry notification.
  • Principles to guide negotiations around cost sharing and fiscal caps. 
  • A briefing from the horticulture industry on its progress developing the Fruit Fly Operational Agreement.
  • A report from Andrew Coleman, the Ministry for Primary Industries Deputy Director, on his department’s current and planned activities across the biosecurity system.
  • Minimum commitments. KVH and Dairy NZ gave a perspective on what minimum biosecurity commitments should be.

KVH will also attend the next GIA Forum in March 2015.

Spring Psa-V progression
11 September 2014

KVH has received several reports of significant exudate showing on orchards in Katikati, Waihi, Opotiki and Gisborne since the weekend. This follows reports of exudate showing on Gold3 in Te Puke, and also on Matua and Chieftan males on some Tauranga orchards last week. This is not surprising at the start of spring and following the high-risk weather last week.

Exudating vines in the Opotiki and Gisborne regions were found during recent mandatory monitoring rounds.  This has resulted in the confirmation of two new infected KPINs in the Gisborne region this week. See this week’s statistics by clicking here.

Exudate ranges in severity and has been discovered on several varieties, including Hayward, Gold3, Hort16A and some male varieties. Males appear worse-affected than females.

Fruit fly pathway analysis released
11 September 2014

The Ministry for Primary Industries (MPI) has identified a potential increase in the threat to New Zealand from the Queensland Fruit Fly (QFF) due to an increase in QFF populations and its spread into previously pest-free areas of Australia.

As a result of this increased threat, MPI has been looking at each pathway and what can be done to better manage the risks according to their recently released QFF Pathway Analysis Report. The analysis started before the two QFF detections this year and was completed after the responses were completed. 

The report gives a good overview of how New Zealand manages the fruit fly threat but does not specifically identify a likely pathway for the two fruit fly found in Whangarei.

The Psa-V Seasonal Management Guide for Spring/Summer 2014-15 is now available on the KVH website – please click here. The Guide helps growers manage Psa-V through spring and summer and provides assistance when updating Psa-V Orchard Management Plans.

Spring is an important time for growers to review their existing Psa-V Orchard Management Plans and consider making any changes to protection strategies based on seasonal orchard observations and new research information.

This season the Guide is also complimented by the Psa-V Seasonal Management Guide Wall Chart which growers should be receiving by post this week, if they haven’t already. The Wall Chart is a great reference tool for placing in staff rooms to support staff and visitor education.

Any changes to the Psa-V Seasonal Management Guide, including updates to the Recommended Product List, will be made to the online version and highlighted through the weekly KVH Bulletin.

New R&D Report - Psa-V leaf spots as inoculum sources
4 September 2014

This project has shown leaf spots continually produced inoculum between November 2013 and March 2014. Under humid conditions, even ‘old’ leaf spots were capable of producing ooze at the edge of the lesion, containing large numbers of viable bacteria. Thus, leaf spots are a continual source of Psa inoculum during the spring and summer seasons.

Border biosecurity statistics
4 September 2014

Last week, the National Biosecurity Capability Network (NBCN) published some interesting facts about the number of border and post border interceptions occurring in New Zealand. These figures show the pressure that occurs at the border on a weekly basis, and the amount of incursions that would occur in New Zealand if we did not have a comprehensive biosecurity system.

In just a single week in February, New Zealand had:

  • 35 new notifications of pests, diseases or organisms and 156 on-going incursion investigations or responses.
  • 115,082 international air passenger arrivals—resulting in seizure of 3,079 risk items and 126 infringement notices (2.7% of passengers with risk items).
  • 13,634 sea containers arrivals into New Zealand—233 required decontamination (1.7 % of containers contaminated).
  • 4,296 cargo lines, of which 792 were inspected and 276 items were seized (6% of cargo lines contained risk items).
  • 500,000 mail items at the international mail centre—635 items required further inspection, 103 risk items treated or destroyed (0.02% of mail items contained risk items).
  • 212  used vehicles or machinery items were imported—52 required decontamination (24.5% used vehicles or machinery contaminated)

As a proportion of total goods entering by each pathway, used vehicles and machinery have a much higher rate of risk items requiring treatment. To determine how this pathway is managed and the level of risk this pathway presents, KVH will profile this pathway in the coming weeks as part of our border profile series.

Fruit Fly Operational Agreement update
4 September 2014

The interim Fruit Fly Council established to develop the Operational Agreement for fruit fly under GIA has met monthly and made good progress in clarifying the approach to be used. 

The majority of the agreement is expected to be completed by the end of September. The remaining issues to address will then be finalising the cost shares between government and industry and agreeing how the industry shares will be calculated.

This work is progressing with a subcommittee made up of KVH, Pipfruit NZ and NZ Wine growers meeting with MPI. The objective is to have this completed before the end of October; and the goal is for the Operational Agreement to come into effect early 2015.

Brown Marmorated Stink Bug
4 September 2014

The Brown Marmorated Stink Bug (BMSB) is causing significant impacts in the USA, and there are concerns regarding the effects this pest could have on horticultural sectors in New Zealand. KVH, along with other horticultural sectors and MPI, have been working to strengthen the border to keep BMSB out, along with developing a surveillance and control programme to detect and eradicate it should it arrive. 

In addition, KVH has meet with New Zealand researchers to agree the focus of the R&D efforts, which include improving our detection technologies at the border, lure and kill approaches, and biological control options that may be available. 

This pest has been assessed by KVH as one of the top five priority pests facing our industry, and there are reports from China (where it is a native) of it causing damage to kiwifruit.

Abandoned orchard update
4 September 2014

Since February 2013 KVH has recorded 93 orchards as abandoned.  Of these, 75 orchards have been removed or returned to a managed state.  Of the remaining 18 orchards; 10 have removal underway but not yet completed (for example, the removed vines are yet to be burnt) and one is being pruned and returned to management. 

KVH is working with the owners of the remaining seven orchards to ensure that National Psa-V Pest Management Plan requirements for their orchards are met.  This means vines must be pruned and tied down by 1 October each year.  Fruit must be picked by 1 July each year and KVH approved products, effective against Psa-V, must be applied to reduce the effects of Psa-V bacterium.

If growers are aware of any further abandoned or unmanaged orchards, anywhere in New Zealand, then please contact KVH on 0800 665 825 or email info@kvh.org.nz.  It is important that abandoned orchards do not harbour Psa-V disease and present an inoculum source infecting neighbouring orchards.  Psa-V can move via wind movement, especially during wet and stormy weather events, for up to 10 kilometres from the infected orchard.

Updating your Psa-V Orchard Management Plan
28 August 2014

Spring is a good time to review your existing Psa-V Orchard Management Plan and consider making changes to your protection strategy based on seasonal orchard observations and new research information.

The online Psa-V Orchard Management Plan template has been improved and now incorporates budwood and rootstock management sections. This avoids the need for growers supplying budwood or rootstock from their orchards to complete separate plans. The updated template is available on the KVH website by clicking here, or going to www.kvh.org.nz/orchard_management_plans.

Growers are reminded an updated Orchard Management Plan must be available with other GAP records as part of the GAP audit process. Also, the application of at least one Psa-V protectant spray from the KVH Recommended Product List is required under the National Psa-V Pest Management Plan (NPMP). All applications of agricultural compounds must be recorded in the Spray Diary.

Better border intervention for transitional facilities
28 August 2014

As advised in last week’s KVH Bulletin (21 Aug) KVH has been advocating for improvements to minimise biosecurity risks on several pathways. Last week focused on the cruise ship pathway, this week will focus on transitional facilities.

Transitional facilities hold un-cleared risk goods for inspection, secure storage or treatment until they receive biosecurity clearance or are re-shipped or destroyed.

While people often think of the border as a small number of places (airports and marine ports) where clearance activities occur, the reality is very different. Most biosecurity clearance activities are occurring at transitional facilities; MPI Inspectors carry out risk profiling when imported goods first arrive at a marine port or airport, clear a small proportion of such goods at those ports (those deemed to pose the highest risk), and then direct most imported goods to transitional facilities where they receive final clearance by a non-MPI accredited person.

There are approximately 6500 such transitional facilities operating in New Zealand, which means our border is very ‘diffuse’.

The key risk is the arrival of ‘hitchhiker’ pests. These tend to be insect pests, and include high-risk organisms of concern to the kiwifruit industry such as, fruit flies, brown marmorated stink bugs and white peach scale.

KVH believes the current policy approach and standards for transitional facilities need to be re-evaluated and strengthened. There are currently too many transitional facilities operating in New Zealand and of variable quality, representing a key vulnerability in NZ’s border arrangements.

Given the level of risk and the key role transitional facilities play in New Zealand’s border, it is critical we have highly trained and skilled people operating to carry out clearance activities within transitional facilities.

KVH shared its concerns with the Ministry for Primary Industries (MPI) in early 2014, and is pleased that MPI appears to be seriously looking at this issue and potential solutions.

2014 Psa-V Seasonal Management Guide - Wall Chart
28 August 2014

This season KVH has produced a visual Wall Chart to support growers with their Psa-V Orchard Management Plans for the upcoming season.

Click here for an online version of the Wall Chart.

The Wall Chart, which growers should receive in the post shortly, provides an excellent tool for raising awareness of Psa-V management and can be placed in offices and smoko rooms to support education of orchard staff and visitors.  

The chart indicates the importance of a multi-layered approach to Psa-V management including:

  • Recognition of Psa-V risk associated with different seasons. 
  • Planning of structured Psa-V monitoring rounds.
  • Well-timed canopy management to minimise Psa-V risk by reducing and protecting wounds. The maintenance of an open canopy structure also helps to optimise spray penetration.
  • A spray plan which includes proven products with different modes of action.
  • Ongoing biosecurity, including orchard hygiene and compliance with movement protocols (particularly plant material) to ensure risk items are not introduced.

The full Seasonal Management Guide for Spring/Summer is being finalised and will available on the KVH website next week.  Any changes to the Guide, including updates to the Recommended Product List, will be made to the website version.

Hort16A showing symptoms as spring approaches
21 August 2014

As we move closer to spring, KVH is beginning to receive reports of Hort16A showing signs of exudate.

This week, monitoring on an isolated Hort16A block in the Katikati region showed 60 percent of the vines had fresh red exudate; and 24 percent of these vines had more than three points of exudate.

Similarly, a significant increase in symptoms were seen on an Opotiki Hort16A orchard being cut over to Gold3.

To date, Hawkes Bay and Gisborne have not reported any new symptoms on Hort16A. Regions where sap flow is a little later, i.e. Kerikeri, are reporting minimal symptoms on Hort16A and other susceptible varieties.

KVH has also received reports of increasing symptoms in Hayward vines in the Katikati/Waihi and Wanganui region. Most of these are in male vines, including Chieftan and Matua males. 

Growers with more susceptible varieties like Hort16A are advised to closely monitor their vines on a regular basis to ensure symptoms are found early and action can be taken quickly.

Using a risk matrix to identify top five threats to the kiwifruit industry
21 August 2014

This week, a paper was presented to the KVH Board that uses a risk matrix to identify the high priority threats to the kiwifruit industry.

On the KVH website there are almost fifty pests and pathogens identified as potential threats to the kiwifruit industry. KVH has developed a risk matrix to provide a structured and objective method of prioritising these organisms into a shorter list for the purpose of readiness and response planning.

The report is a draft and we will be requesting subject experts to review the methodology and results of this report. However, we encourage growers to read the material and engage with KVH their views on this subject.

It is important to also remember the next incursion may not be the organism we have prepared for. Therefore, it is important to maintain a diversity of organisms in the focus group if possible and this is reflected in the report where organisms have finished with equal risk ratings.

The top five threats identified in the report are:

  • Fruit Flies (Mediterranean, Oriental and Queensland)
  • Brown Marmorated Stink Bug
  • Psa—non NZ pathovars
  • Spotted wing drosophila
  • Ceratocystis fimbriata

KVH advocates increased border intervention on cruise ships
21 August 2014

Following a review of biosecurity risks associated with Port of Tauranga and Rotorua Airport last year, KVH identified initial concerns with incoming cruise ships and raised these with the Ministry for Primary Industries (MPI).

KVH has been advocating for improvements that further minimise biosecurity risks through the cruise ship pathway. These include: 

  • Improved understanding of the risks. By buiding a view of what MPI is intercepting when they search passengers and by measuring slippage.
  • Increased use of detector dogs on this pathway. To intercept risk items and act as a ‘ deterrant’.
  • Fruit and vegetables to meet NZ Import Requirements. This is a long-term strategy and what KVH believe is key to substantively eliminate risk. If implemented, this will mean all cruise ships arriving into New Zealand will only be able to load fruit that meets New Zealand’s Import Health Standard for fresh produce—the same standards applied to imported fruit bought in New Zealand supermarkets.

KVH acknowledges that some key improvements have been made by MPI over the last 12 months to tighten biosecuirty through this pathway.

MPI are now using dogs for all first port of arrivals and many second ports of arrival. Detector dogs have been used on 150 cruise ship visits resulting in the interception of 500 biosecurity risk items, of which 76 percent were fresh produce.

The cruise ship industry has more than doubled in size over the last five years (Cruise New Zealand). These cruise ships enter New Zealand waters from Australia or the Pacific Islands, regions harbouring high-risk pests and diseases including fruit flies, which are the greatest biosecurity threat to New Zealand’s horticultural industries.

KVH will continue to proactively strive for even better border intervention to reduce risk to the kiwifruit industry.

Copper products added to KVH Recommended Product List
14 August 2014

Kocide® Opti™ now has a full-label claim for the control of Psa. This was approved by the ACVM group of the Ministry for Primary Industries (MPI) on 31 July 2014. Kocide® Opti™ is a copper hydroxide product which may be applied throughout the year within a Psa-V management programme. It should not be applied to open flowers. The recommended application rate for dilute spraying is 70–90gms/100L.

HORTCARE® Copper Hydroxide 300 also received a new registration from ACVM on 1 August 2014 with a limited label claim granted for the control of Psa-V. When dilute spraying the recommended application rate for this product is 50-90gms/100L through the budbreak to harvest period; and 70–90gms/100L through the post-harvest and dormancy periods. Again, avoid application to open flowers.

The KVH Recommended Product List has been updated to include these products and they will also be included in the 2014-2015 ZESPRI Crop Protection Standard for Psa control.

Psa-V protectant use
14 August 2014

As advised in previous KVH Bulletins, KVH has been undertaking Spray Diary analysis over the last month looking at the use of Psa-V protectants throughout the country over the last growing season.

Through this analysis, a number of KPINs that have not applied any of the listed Psa-V protectant sprays to their crops have been identified. KVH will work with packhouses and the growers to identify the reason no protectants have been applied.

Mandatory monitoring - reporting due 10 September 2014
14 August 2014

Mandatory monitoring should be taking place in Exclusion and Containment regions over the next two weeks, with reporting due to KVH by 10 September 2014.

Information from these rounds is important to KVH. Firstly, to confirm Exclusion regions are still clear of Psa-V symptoms; and secondly, to track progression, if any, on Psa-V positive orchards in Containment regions.

To simplify reporting for growers, KVH has an online monitoring reporting form for growers available on the website. This easy-to-use tool allows growers to submit monitoring results for each variety on their orchard. Click here to access the online reporting tool.

Not-Detected orchards
14 August 2014

KVH records show a number of ‘Not Detected’ orchards have been requesting plants from Psa-V positive nurseries. Movement controls prohibit this; and therefore requests for these movements are declined.

To ensure KVH records are accurate and growers are not disadvantaged, it is important growers notify KVH if Psa-V symptoms are showing on an orchard for the first time. Visual verification of Psa-V symptoms from suitably qualified people (i.e. Packhouse Psa Managers) will be accepted in lieu of lab-testing.

Growers have a legal obligation under the NPMP to notify KVH within 48 hours if their orchard shows Psa-V symptoms for the first time.

Postharvest operators in Recovery regions have recently been sent a list of their growers who are still recorded as ‘Not Detected’. If you are unsure of your status please contact your packhouse or KVH on 0800 665 825.

KeyStrepto
14 August 2014

As KeyStrepto™ has been granted a limited label claim by ACVM, there is no longer a requirement for KVH to complete auditing prior to KeyStrepto™ application. Meeting the conditions of use for KeyStrepto is  100 percent grower responsibility.

KeyStrepto™ must not be applied within seven days of the first kiwifruit flowers opening (male or female). Open flowers should be kept to an absolute minimum in the sward by mowing and/or applying herbicides if required.

Before applying KeyStrepto™ a Site Inspection Record must be completed by whoever is responsible for the orchard. This Site Inspection Record is available from the KVH website here. KVH is currently reviewing its apporach to random auditing this year.

It’s important the use conditions for KeyStrepto™ are adhered to, as misuse could pose significant risk to the continued use of this valuable tool within the kiwifruit industry.

KPCS audit results in Psa-V discovery
14 August 2014

Last week a nursery applying for Kiwifruit Plant Certification Scheme (KPCS) certification was found to have Psa-V for the first time.  It was detected by KVH during testing which is part of the certification process.

The result follows a severe weather event in the region and comes as a disappointment for the nursery which had been following KVH Protocols and working towards the Core Standard with many systems in place to achieve certification.

KVH is working with the nursery to manage the risks and assist with recovery over the longer term; along with tracing of plant movement, contacting affected growers and working with regional coordinators in these areas.

Nurseries selling plants under the KPCS must pass an external systems audit and have independent verification they are free of the target pests and diseases.

KVH continues to work with kiwifruit nurseries to improve biosecurity practices and certify them under the KPCS Core Standard. By purchasing certified plants, growers have assurance they are investing in the best possible start when establishing new vines.

Kerikeri Controlled Area and Notice of Direction lifted
7 August 2014

In October 2012 KVH established a ‘Kerikeri Controlled Area’ to help prevent the spread of Psa-V in the Kerikeri region.  At the time one Kerikeri orchard had been identified with Psa-V.

Psa-V has now been identified on 26 orchards throughout the Kerikeri region, including orchards outside of the Controlled Area. Therefore, the KVH Board has decided to remove the Kerikeri Controlled Area; and lift the Notice of Direction issued to growers, effective immediately.

Although the notice has been lifted, the National Psa-V Pest Management Plan (NPMP) rules and requirements still apply.  All orchards within the Kerikeri Psa-V Containment Region have rules covering movement of risk items including plants and machinery (within, into and out of the Region), application of crop protection products, vine management, monitoring and reporting of Psa-V symptoms.

Cane testing for nursery certification
7 August 2014

The new Kiwifruit Plant Certification Scheme (KPCS) is supported by robust sampling and testing protocols developed by Plant and Food Research (P&FR). These protocols are leaf-based which presented the challenge of how to reliably test during winter when outdoor plants have no leaves.

P&FR have conducted research into cane testing as a potential solution to this challenge. The final report from this research concluded the uneven distribution of Psa-V in the vines made detection unreliable, compounded by the low levels of Psa-V present in the vines during winter.

Positive results produced by cane testing were true positives. However, there was not sufficient confidence in cane sample selection to confirm a non-detected result on cane samples for nursery certification purposes.

Therefore, the KPCS will continue to use leaf-based testing to provide the appropriate level of confidence for  plant certification purposes; and nurseries will not be tested for certification purposes when leaves are not present .

During August the use of Hydrogen Cyanamide (often referred to as Hi-Cane) as a bud-break enhancer increases. It is recommended that copper is not applied within a week either side of the application of a bud-break enhancer to avoid potential phytotoxicity issues.

Growers are reminded that strict conditions apply when using Hydrogen Cyanamide to comply with Council air plans. This includes notifying neighbours at lease 12 hours prior to the application of Hydrogen Cyanamide, clear signage must be displayed at orchard entrance and low-drift spray technology is now compulsary.

Preparing for a high-risk spring
7 August 2014

As a result of the wet autumn and early winter weather experienced in many parts of the country, KVH prepared a ‘forward planning’ paper looking at the possible flow-on effects of a cold, wet spring.

The paper was based on learnings from experiences in France during the spring of 2013-14 and was discussed at the recent KVH board meeting. A number of recommendations were made about how we could better assist the industry should we see similar conditions in New Zealand this spring.

National Science Challenge
7 August 2014

In May last year the government announced a new direction for science investment by establishing ten ‘National Science Challenges’. The National Science Challenges are established to tackle some of the biggest science-based issues and opportunities facing New Zealand and take a more strategic approach to science investment.

One of the National Science Challenges—New Zealand’s Biosecurity Heritage—is of particular interest to the horticulture sectors as it will direct future investment in both biosecurity and biodiversity research.

MBIE have recently approved the 10-year research plan and allocated new funding of $25.8m for the first five year period.

The research undertaken in this Challenge will be designed to protect and manage New Zealand’s biodiversity, improve biosecurity and enhance the country’s resilience to harmful organisms.

A broad range of stakeholder industries, including KVH, HortNZ and New Zealand Wine Growers, were involved in the development of this challenge and preparation of the research plan. This was through representation on a focused stakeholder advisory group and stakeholder workshops.

KVH and other horticultural sectors will continue be actively engaged. KVH Chief Executive, Barry O’Neil has been appointed to the Governance Group; and KVH Biosecurity Programmes Manager, Andrew Harrison is part of the Industry Advisory Group.

2013/14 Potted Plant Field Trial Report - Elicitors on Gold3 Potted Plants

This trial was established to determine the efficacy of a range of elicitors and CPPU products in inducing a plant immune response to Psa-V, using Gold3 potted plants. All of the elicitors significantly reduced leaf spot in Gold3.

None of the elicitors significantly reduced secondary symptoms, although secondary symptom expression was low in this trial.

Importance of recording spray applications
7 August 2014

Last week the KVH Bulletin (31 July) highlighted a number of orchards throughout New Zealand that had not applied a Psa-V protectant spray during the last growing season.

Spray Diary analysis is currently being carried out by industry; and it’s important to remember there is real value gained from the analysis of spray patterns. However, if all sprays are not recorded, it gives industry an inaccurate picture. Furthermore, in the event of an issue arising from a spray application, an accurate Spray Diary record is an invaluable tool to help identify how and why the issue occurred.

Under the rules of the Zespri Crop Protection Standard (CPS) all applications of agricultural compounds must be recorded in the Spray Diary. This includes applications to the orchard floor and shelter.

Growers should ensure all sprays applied post-harvest are recorded in the Spray Diary, along with all sprays applied to crops going forward.

Psa-V symptoms in Bay of Plenty male vines
7 August 2014

This week some Bay of Plenty growers have reported exudate symptoms in their male Hayward vines.  Often observations by pruning teams have triggered monitoring rounds where these have been found.

Many monitored blocks appear free of symptoms. However, in other blocks symptoms range from just a few vines with exudate to a high number of vines with exudate, particularly in blocks with Matua males.

This symptom increase in symptoms is likely due to increased sap flow as spring approaches. Growers are recommended to begin directed monitoring rounds focussing on higher risk plants (i.e. males, young, stressed) and orchard areas with less favourable growing conditions.

Cutting out infection, followed by bagging and removal of infected material from the orchard, is recommended to avoid inoculum build-up on orchard. Growers are urged to plan a proactive spring spray programme to minimise the chances of infection resulting in leaf spot and bud infection later in the season.

Some Gold3 cane collapse is also being seen on orchards. Again, cutting out infected material coupled with a proactive spray programme is recommended.

Importance of keeping spray diaries up to date
31 July 2014

Under the National Psa-V Pest Management Plan (NPMP) growers in all regions are required to apply protective spray products with proven efficacy against Psa-V to their vines.

KVH, in conjunction with Zespri, have analysed grower spray diaries for the 2013–2014 season and it appears a number of orchards have not applied a protective spray product (see graph above). It is possible that some sprays, particularly through the dormant period, have not been entered in the spray diary.

It is important spray diaries are kept up to date and include all sprays applied to an orchard over the entire growing season.  KVH will follow up with orchards that don’t appear to be applying protective sprays.

Certified kiwifruit plants under the ‘Core Standard’ of the Kiwifruit Plant Certification Scheme (KPCS) are now available for growers to order.

The first two nurseries selling KPCS certified plants are now listed on the KVH website. Two more nurseries also being audited under the Core Standard are awaiting testing results and are expected to be included on this list shortly.

A list of kiwifruit nurseries including those who are now part of the KPCS, is available on the KVH website here. Purchasing certified plants gives growers assurance they are investing in the best possible start for their new vines. Growers are reminded to order plants well in advance to ensure that nurseries can meet industry demands.

Detector dogs at Auckland Biosecurity Centre
31 July 2014

Last week KVH staff visited the Auckland Biosecurity Centre to see first-hand MPI’s detector dog programme.

MPI have their own detector dog breeding programme which is a cost effective way of producing fit for purpose biosecurity detector dogs. The breeding programme now has 40 dog teams operating throughout New Zealand at various ports of entry.

MPI now have detector dogs at all cruise ship first port of arrivals and many second port of arrivals. Detector dogs are now used to screen disembarking passengers from 150 cruise ships. This has resulted in the seizure of 500 risk items, of which 76 percent was fresh produce (of particular concern given its capacity to host fruit fly).

Detector dogs have been a fundamental component of biosecurity interventions at the border for many years. MPI is now also working to train a new line of dogs for a different purpose, post-border incursions. These incursion dogs can be used in the field and trained to detect any pest and may be especially useful for pests for which there are no pheromone traps available.

Review of NZ Import Requirements for kiwifruit pollen
31 July 2014

Following the discovery of Psa-V in New Zealand in 2010, the Import Health Standard (IHS) for pollen was immediately amended by the Ministry for Primary Industries (MPI) to prohibit the import of kiwifruit pollen. To date, the importation of pollen into New Zealand remains prohibited as the potential risk of introducing further variants of Psa-V and other pathogens is unknown.

After KVH raised concerns about the possibility of Psa-V impacting male kiwifruit vines and creating a pollen shortage, MPI was asked if there was a safe way to import pollen.

MPI sought input from a Technical Working Group made up of experts from the kiwifruit (incl. KVH, Zespri and other independents), bee and pollen industries. The aim of this Working Group and subsequent MPI analysis was to determine the risk posed by imported pollen; and the potential to import it, preferably in emergency situations only (e.g. if there were to be a significant shortage of pollen in New Zealand).

MPI have drafted an assessment of the potential for Psa to be associated with imported pollen and the potential consequences if Psa (Psa-V or other variants) was to enter and establish in New Zealand. Other pathogens which may also be associated with imported pollen, and which may impact on the kiwifruit or bee industries have been identified by MPI, but have not yet been assessed.

Following a meeting of the Working Group in mid-July, MPI is currently concluding its assessment of Psa and KVH expects an update on the assessment from MPI in the next couple of weeks. KVH believes it is very unlikely this process will result in the imported pollen ban being lifted as other pathogens associated with pollen still require careful assessment.

While New Zealand does not currently have a pollen shortage, a bad Psa year could possibly impact future pollen supply.

Therefore its essential growers plan ahead for future pollination requirements.

  • Manage your male vines—develop low-vigour growing systems
  • Assess the health of your male vines—diseased males can impact future pollination requirements
  • Detecting diseased males early will allow time to assess your future pollination requirements
  • If males need to be cut out, ensure you have a plan for future pollination requirements
  • Order pollen early from KVH-registered pollen providers for future pollination requirements
  • Arrange harvest of early flowers for pollen milling wherever possible
  • Store pollen for next season wherever possible
  • Graft to more Psa-tolerant varieties

Change to KVH Protocol - Fruit Bins
31 July 2014

Last week KVH held an audit debrief with packhouses; and as a result some changes have been made to KVH Protocol—Fruit Bins.

The main change allows postharvest operators in Recovery regions to have their cleaned and sanitised bins (destined for Whangarei, Kerikeri and NW Auckland) inspected by KVH now—before being placed in sealed coolstores for next harvest. This will avoid double-handling and save packhouses time and expense.

A KVH inspection sticker will be attached to checked bins so growers can identify them on arrival to the orchard next harvest. A percentage of these bins will again be inspected by KVH before being dispatched to orchards next season.

Reminder to order nursery plants in advance
24 July 2014

A key message KVH is picking up during nursery visits relating to the Kiwifruit Plant Certification Scheme (KPCS) is that growers are not providing nurseries with orders far enough in advance.

Without a reliable estimate on anticipated demand for the next season, nurseries take a conservative approach to avoid getting left with unsold stock.

Growers should order plants in as far advance as possible, preferably one year in advance to avoid any shortage in supply.

Additionally, growers should only be purchasing plants that have KVH certification accreditation or are registered with KVH. A list of nurseries and their status is available on the KVH website.

Mandatory monitoring
24 July 2014

Regular monitoring is an important part of Psa -V prevention and management plans, particularly following wet, windy and frosty weather.

Growers on ‘Not Detected’ orchards, especially those in Exclusion regions, should be regularly monitoring their vines over winter and spring for signs of Psa-V infection. Those on Psa-V positive orchards should be monitoring to identify any canes and/or vines showing signs of infection which need to be removed to prevent spread of infection.

As part of KVH requirements under the NPMP we need to collect data and report on Psa-V progression to ensure the objectives of the plan are being meet.  To meet these objectives we require growers to report their monitoring results.

August mandatory monitoring results from the following orchards must be submitted to KVH by 10 September 2014:

  • All orchards in Exclusion regions
  • All orchards in Containment regions
  • Not Detected orchards in Recovery regions

Note—Psa-V positive orchards in Recovery regions are encouraged to send in their results but this is not mandatory.

An updated online mandatory monitoring form will be available on the KVH website next week.

Harvest bin inspections
24 July 2014

Following a recent de-brief, it was revealed KVH audited 100 percent of bins (14,863 bins) in the 2014 harvest season that were supplied to Whangarei, North-West Auckland and Kerikeri from Recovery region packhouses. More than 180 of these bins contained kiwifruit plant material and were returned to the packhouse for cleaning and sanitising. No bins containing plant material were sent to any orchards.

Before sending bins to other containment regions (Wanganui, Coromandel, Gisborne and Hawkes Bay) packhouses were asked to advise KVH, and a 10-20 percent sample of these bins were inspected by KVH auditors along with the packhouse sanitising and inspection systems.

KVH received no complaints from any growers about the cleanliness of the harvest bins delivered to their orchards.

As reported in the KVH Bulletin (19 June) ongoing testing as part of the KVH/Zespri R&D programme is underway to identify early any strains of Psa-V showing potential resistance to protective compounds.

The latest results from Verified Lab Services (VLS) for Streptomycin/copper resistance testing confirms to date, no resistance has been detected.

This is an ongoing testing programme. In future we are looking to improve the testing process by including more KPIN samples and extending outside the Te Puke region.

Growers who have used KeyStrepto™ or copper and would like to be part of the resistance monitoring programme by allowing samples to be collected from their orchard can register their interest with KVH at info@kvh.org.nz.

Psa-V in Korea
17 July 2014


Psa-V was detected in Korea in the mid 1980’s and that strain is now referred to as Biovar 2. This virulent biovar was a contributing factor to the removal of uncovered Hayward orchards on Jeju Island where the Zespri Gold orchards are now located.

A new Psa-V strain has been recently identified in Korea—on the mainland and on Jeju Island. We understand this strain is part of the Biovar 3 group (same group as the New Zealand strain). The Biovar 3 is having an impact on multiple varieties including Hort16A, as has other strains in the past. New Zealand and Korean researchers are working on characterising the bacteria to determine its origin.

Zespri is supporting its Korean growers by providing information and best practice techniques to manage Psa-V.

Protection especially important during wet weather
17 July 2014

Almost twice as much rainfall than last year has been recorded in June 2014 at the Te Puke Research Orchard (TPRO) (see graph above). Similar rainfall patterns have occurred in other parts of the country with winter 2014 shaping up to be much wetter than last year.

Many growers will be struggling to complete their normal orchard activities in between this wet weather. The application of protectant sprays before and after pruning is particularly important through this time.

KVH recommends the application of a minimum of five copper sprays during dormancy. Research and experience has shown a strong copper programme over the dormant period has significant advantages the following spring.

It is reported around 500ha of Gold3 orchards have now installed hail netting, with many more growers wanting to install it.

Growers see a number of advantages to protect their crops from wind and hail, including additional Psa-V protection. Good on-orchard shelter reduces physical damage (wounding) which creates Psa-V entry points.

First nursery certification audits take place
17 July 2014

Last week the first nursery audits took place for for the ‘Core Standard’ of the Kiwifruit Plant Certification Scheme (KPCS). Certified plants from participating nurseries will be available for purchase from next week.

By tomorrow (Friday) four nurseries will have been audited in Nelson, Gisborne, and Kerikeri. There will be a short delay pending the outcome of diagnostic tests before plants are available from some of these nurseries.

Audits are carried out by external auditors. However, KVH is maintaining visibility and ensuring consistency of the Scheme by reviewing nursery manuals prior to the audit, and being present at all initial audits.

The KPCS was launched in May this year and means growers will be able to purchase certified kiwifruit plants from participating nurseries, giving them assurance they are investing in the best possible start for their plants.

A list of participating nurseries will be available on the KVH website as nurseries complete the process to sell certified Core Standard plants. For more information visit www.kvh.org.nz/kpcs.

Movement restrictions of kiwifruit wood for firewood use
10 July 2014

At this time of year a lot of kiwifruit wood is sourced and moved for the use of firewood. The movement of kiwifruit wood for firewood use is covered by KVH Protocol—Other Plant Material.

Key movement controls from the Protocol are outlined below.

  • Kiwifruit plant material for firewood use must not be moved from any Psa-V positive orchard or site unless prior approval from KVH has been given.
  • Plant material for firewood use must not be moved between regions.
  • Recovery regions—plant material for firewood use may move within the same Recovery region if sourced from ‘not-detected’ orchards.
  • Containment regions—plant material for firewood use may move within the same Containment region if sourced from ‘not-detected’ orchards. However this requires authorisation by KVH prior to movement.
  • Exclusion regions—plant material for firewood use may move within the same Exclusion region.


If you are unsure about the movement of plant material for firewood use, or have any queries, please contact KVH on 0800 665 825 or email info@kvh.org.nz before you move it.

Kerikeri Psa-V progression
10 July 2014

Those who observe KVH’s weekly statistics will have noticed Psa-V has progressed in Kerikeri recently, with Psa-V identified on seven new orchards in June.

Last week Zespri’s Shane Max, KVH Operations Manager, Peter Mourits and Te Puke grower, Robbie Ellison visited growers on newly infected Kerikeri orchards to discuss the situation and options going forward. The team also held a grower meeting which was attended by more than 50 local growers.

Key points from the Kerikeri visit

  • In most cases, the recently infected orchards received fewer copper sprays over the wet autumn weather than other local orchards; and infection was found in less sheltered parts of the orchard.
  • Psa-V has been found in a number of young Gold3 orchards, while disease was not present in neighbouring Hort16A orchards where more regular copper has been applied. This highlights that while Gold3 is more tolerant to Psa-V it still requires regular protective sprays, particularly in wet, cool conditions.
  • Growers were reminded of the importance of continuous removal of all infected material, regular protective sprays and the need for orchard hygiene.
  • Psa-V progression in Hort16A has been slower than expected. This is partly attributed to the warm, dry weather earlier in the year, regular copper sprays over the wet weather and early removal of any Psa-V symptoms.
  • Spray diary analysis shows Hort16A blocks in Kerikeri have had an average of nine copper applications over the last season, compared to six applications on Gold3 blocks.
  • Overall, the management of low vigour males on some orchards was excellent; and its obvious Kerikeri growers are learning from experience in other regions. 
  • Growers have been asked to be vigilant and carefully monitor orchards with the expectation that more orchards will express red exudate when sap starts to flow in spring.

France Psa-V update
10 July 2014

During the French spring (April/May) Hayward orchards in the Tarn et Garonne area were expressing severe exudate, causing panic amongst some local growers. KVH Director Craig Thompson visited at this time to understand the situation and his report can be found in the July/August Kiwifruit Journal.

An update from Zespri’s Severine Brun in France, reports those growers who applied a consistent and robust protective spray programme over the past few years have reported little or no Psa-V symptoms; and unlike last spring in France, this spring has been kinder to French growers, with temperatures through June being warmer and drier than the 30-year average.

As a result, less Psa-V symptoms have been observed, flower loss is much lower than last year and growers are generally much more positive about the ability to continue growing kiwifruit in a Psa-V environment.

Hort16A continues to be a badly affected variety and those few growers who are still growing it are trying to achieve another harvest.

Gold3 is looking good, with very limited symptoms, mostly noticed in spring (dry canes and/or exudate on a few vines per block).

Kasumin removed from CPS for 2015 season
3 July 2014

Zespri has removed Kasumin® from the Crop Protection Standard (CPS) for the 2015 season while further research is done to confirm the most effective use pattern. This research is expected to confirm the optimal pre-flowering withholding period for Kasumin® and the number of applications allowed in the pre-flowering period.

Zespri has taken a conservative approach to this Psa management tool in this case, as the suite of Psa-targeted products is considered sufficient to manage Psa this season.

Growers can use up to four applications of KeyStrepto™ on producing and non-producing vines for the 2015 season, though no more than two consecutive applications are allowed without using another Psa-targeted product – e.g. copper.
 

  • Between 13 June and 31 July 2014, KeyStrepto™ use is permitted with a Justified Approval (JA).
  • A JA is not required from 31 July 2014 until seven days before the first kiwifruit flowers opening (male or female).
  • KeyStrepto™ must not be used during flowering.
  • An alternate Psa control product – e.g. copper – must be used after a maximum of two consecutive KeyStrepto™ applications.

Refer to the KeyStrepto™ User Guide for detailed rules of use. Growers are responsible for ensuring all use conditions are complied with. KVH no longer conducts pre-use audits.

The KeyStrepto™ User Guide and Site Inspection Record are available on The Zespri Canopy and the KVH website.

People working on orchards at this time of year can provide extra resource for carrying out monitoring duties. Growers should be alerting their orchard workers to be on the lookout for signs of Psa-V infection, particularly cane dieback and exudate.

Don’t forget hygiene measures should be in place to prevent introduction or spread of infection between plants, rows, blocks and orchards.

GIA Secretariat visits KVH
3 July 2014

The Government Industry Agreement (GIA) Secretariat visited KVH staff today to give an update on the GIA, including where other primary industries were within the process. The GIA Secretariat facilitates implementation of the partnership described in the GIA Deed and acts in the interests of all Deed Signatories.

As reported in the KVH Bulletin (22 May) the kiwifruit industry was the first to sign the GIA Deed on 20 May.

On 22 July, New Zealand Pork will be the next industry to sign the GIA Deed, representing all New Zealand pork producers.

Like the kiwifruit industry, by signing the GIA Deed, NZ Pork is recognising that biosecurity is a major risk to New Zealand pork producers and that their industry is acting responsibly in taking all possible steps to mitigate this risk.

KVH Chief Executive, Barry O’Neil, spent two days in Wellington this week discussing financial arrangements for GIA as part of a joint working group; and the development of the Operational Agreement for Fruit Fly.

Remove infection during winter
3 July 2014

Winter is an opportune time for growers to remove visible signs of infection from their orchards, including cane dieback and exudate. Ideally, growers should do this before winter pruning. Cut back 40cm from signs of infection.

Removing infection allows pruners to structure vines accordingly and minimise later potential impacts on production.

RightThe KVH Psa-V Risk Model forecasts further heavy rainfall in Opotiki

Continuing wet periods across the country are keeping Psa-V risk elevated. Growers should avoid pruning in wet conditions or when rain is imminent. Ensure all pruning cuts are protected prior to the next rainfall event and tools are sanitised between vines. Pruning staff should be asked to report signs of new Psa-V infection. Monitoring of males, especially in high risk blocks should be undertaken.

Consult the KVH Seasonal Management Guide—Autumn/Winter for best practice information and guidance. Growers unable to access their orchards because of wet ground conditions may consider aerial applications of copper. Address areas where soil drainage is an issue. Stressed vines are likely to be more susceptible to Psa-V.

Removal of Hort16A canopies
26 June 2014

Growers in the process of removing Hort16A should ensure canopies are well protected with copper sprays to minimise the chances of infection and Psa-V spread.  Ideally, remove any Psa-V infected material and dispose of it by on-site burial or burning. If removed canopy is remaining within the block, fine mulching and use of digesters to speed break-down of is highly recommended.

Psa-V can survive for at least 15 weeks on the orchard floor in prunings and infected plant debris, presenting an ongoing Psa-V risk. Removal of this material will benefit new grafts next spring.

This recommendation also applies to any canopies where infection may be present.

Caution when travelling overseas
26 June 2014

A reminder to all when travelling overseas: be vigilant with biosecurity measures particularly if you have been visiting kiwifruit orchards. Shoes must be free of soil material and clothes worn in an orchard environment must be washed before entering New Zealand orchards.

On arrival into New Zealand it is important you declare any visits to foreign orchards to MPI Border staff so they can ensure all necessary measures are taken to prevent the accidental introduction of unwanted pathogens that could be devastating to our industry (such as Ceratocystis fimbriata).

Ceratocystis fimbriata update
26 June 2014

Ceratocystis fimbriata is a fungal pathogen causing widespread damage to the Brazilian kiwifruit industry (see KVH Bulletin, 20 Feb). The disease is of significant concern to the New Zealand kiwifruit industry and efforts are being made to increase our understanding of the disease—both to prevent it from entering our borders and to effectively manage it should it arrive.

Efforts that are being made to understand this pathogen include:

A full literature review on Ceratocystis fimbriata on kiwifruit and other crops by an international expert in this field. This report is due in early 2015 and will include;

  • Impact of the disease on crop production;
  • Taxonomy of Ceratocystis fimbriata complex which is complicated and has possibly been confused in some instances;
  • How the pathogen has spread and control measures that have been effective on other crops (there are no controls reported to be effective on kiwifruit);
  • Evaluation of Ceratocystis wilt in kiwifruit in Brazil and potential for disease impact if strains aggressive to kiwifruit were introduced to New Zealand.
  • Measures that should be deployed to reduce the risk of introductions of new strains of C. fimbriata to New Zealand and what could be done to minimise losses if a virulent strain was introduced.

Another research project being developed will use molecular techniques to determine the similarity of the Brazilian kiwifruit strain with the strain found in New Zealand kumara. This project would identify any underlying basis for differences in pathogenicity between the strains and would result in a DNA based detection test.

Japanese officials visit NZ
19 June 2014

As advised in the KVH Bulletin (5 June) Psa-V was recently identified in Japan. To date, the disease has been identified in six Japanese prefectures: Ehime, Fukuoka, Saga, Okayama, Wakayama and Shizuoka.

This week officials from Japan’s Ministry of Agriculture, Forestry and Fisheries (MAFF) visited KVH and Zespri to learn more about how to best manage the disease. The Japanese visit to KVH included an update on Psa-V in New Zealand; best practice orchard management; an overview of the NPMP; movement controls; the Kiwifruit Plant Certification Scheme; and communications to industry and growers.

Around one percent of the total kiwifruit acreage in the infected areas has been affected by Psa-V in Japan. Control measures include cutting out and disposing of infected material and proactive spray control.

A second Japanese MAFF visit also occurred during the week in Wellington with MPI to discuss future export conditions of New Zealand pollen and budwood.

Psa-V compound resistance
19 June 2014

It’s possible for Psa-V to change genetically in order to develop resistance to chemicals or compounds that are currently used by growers to manage the disease. In other words, they would no longer be effective against Psa-V.

As few products are currently known to have efficacy against Psa-V, the loss of one or more of these due to resistance would make Psa-V much more difficult to manage. This would be a significant issue for the kiwifruit industry.

To date, Psa-V resistance has not been identified in New Zealand kiwifruit. However, overseas experience has seen bacterial resistance develop against copper and antibiotics. It can happen as a result of products not being used properly, or being over-used.

Ongoing testing as part of the KVH/Zespri R&D programme is underway to identify early any strains of Psa-V showing potential resistance.

It’s essential the kiwifruit industry is aware of this potential issue, and carries out best-practice management to avoid resistance.

Preventing Psa-V developing compound resistance

Growers and the industry can help reduce the risk of Psa-V developing compound resistance by following these simple steps.

  • Always read and follow label instructions, including the recommended label rates. Using products at lower rates can cause resistance to develop.
  • Use a combination and/or alternate effective products. This avoids applying the same compound/chemical multiple times in a row—making resistance more difficult to develop.
  • Reduce diseased material in the orchard by ongoing management and removal of infected material.
  • Maintain best-practice orchard hygiene.

A coordinated approach incorporating the above strategies across the entire industry will reduce the risk of resistance developing.

Kiwifruit growers who believe spraying is providing no control, or suspect compound resistance on their orchard, should contact KVH on 0800 665 825 or email info@kvh.org.nz

KVH will then assess the situation and carry out additional testing for resistance as required.

Protect orchards over winter
19 June 2014

Heavy rain over the last two weeks means Psa-V inoculum levels are likely to rise, increasing the potential for infection spread.

Growers need to be proactively monitoring their orchards to detect any signs of infection early. Three new orchards have been identified with Psa-V in the Kerikeri region in the last week. All had cane dieback symptoms on Gold3.

Pruners and grafters are working on orchards during this time of year, and if trained to identify Psa-V symptoms, can provide another opportunity for symptoms to be identified and removed.

Growers must be vigilant about who they allow onto their orchards—both where they have come from and what equipment/tools they are bringing onto the orchard.

KVH have protocols in place to restrict high-risk movements and growers need to be aware of these. Strict attention to orchard hygiene will minimise the risk of disease transferring between vines, orchards and regions.

With pruning and grafting activities taking place, all growers should be familiar with the KVH Protocol—Budwood regarding movement controls.

If considering planting rootstock growers need to be sourcing plants from either KVH Accredited or KVH Registered Nurseries and ensuring that the movement protocols are adhered to.

Improvements to KVH website search function
19 June 2014

Industry feedback from the KVH Communications Survey strongly suggested the search function on the KVH website, and in particular within the R&D section, needs improvement.

After investigating limited options it was decided implementing a dedicated ‘google custom search engine’ on the KVH website will be the most effective option. This option will effectively increase the ability of users to find KVH website content.

However, to use the google search to the best of its ability, and to avoid breaching Google’s Terms and Conditions, the ‘restricted’ documents on the website will need to be made available to all website users. Therefore:

  • KVH plans to open the R&D section to all users so these documents will no longer be ‘restricted’.
  • Other restricted documents, including Zespri variety information, monitoring results and variety-specific case studies, will be removed from the website and available on request.
  • The KVH Psa-V Risk Model will remain a ‘restricted’ tool for New Zealand growers, and accessible to registered users only.

If growers have any concerns, please contact KVH on 0800 665 825 or info@kvh.org.nz.

Border Interventions on Import Pathways - Profile No. 2 International mail
12 June 2014

The second border pathway to feature the KVH profile series is International Mail. Each year 40 to 50 million mail items are processed at New Zealand’s International Mail Centre, located near Auckland Airport. MPI’s biosecurity team use risk profiling, x-rays and detector dogs to screen and process incoming mail on this pathway and seize around 40,000 biosecurity risk items annually.

Mail is considered a low risk pathway for the entry of fruit fly host items; and in the past 12 months only one fruit fly host item has been intercepted on this pathway. However, as a precautionary measure in response to this year’s Queensland Fruit Fly finds in Whangarei, MPI have increased detector dog presence to 100 percent coverage for all high risk mail items.

Potted Plant Field Trial Report - Elicitors on Gold3 Potted Plants
12 June 2014

Using Gold3 potted plants, this trial was to determine the efficacy of a range of elicitors and forchlorfenuron products in inducing a plant immune response to Psa-V.

All the elicitors, except Alexin, significantly reduced leaf spot in Gold3 group up to 37 days post Psa-V inoculation (p < 0.05). None of the elicitors significantly reduced secondary symptoms. Actigard™, which was used as a positive control, had the greatest effect in reducing leaf spotting and secondary symptoms compared with the Psa-V group.

Testing the products in this trial on other kiwifruit varieties may result in a different response to ones observed in this trial, as an elicitor response may be kiwifruit variety-specific.

Severe weather event - protect your vines from Psa-V now
12 June 2014

Due to the severe storm being experienced around the country, growers should be protecting their vines by applying a protective copper spray as soon as possible following the rain. Storm damage, including multiple leaf scars from leaves being stripped from vines, create Psa-V entry points.

Copper applications have shown to be the most effective control of Psa-V during the post-harvest and dormancy periods.

Follow label instructions and use winter rates.

Growers with high-risk blocks, including those showing Psa-V infection and young vines, may also consider antibacterial products.

Tauranga regional boundary changes
5 June 2014

KVH recently reviewed the boundaries of existing Recovery regions within the Bay of Plenty.

After consultation with grower groups and the KVH Board, it was decided to combine Tauranga East and Tauranga West into one region: Tauranga.

Tauranga was originally one region when Psa-V was first establishing in the Bay of Plenty. As Psa-V progression differed across the Bay of Plenty, and progression control was better managed in smaller geographical areas, a decision was made in 2012 to split Tauranga into two regions.

However, now that more than 75 percent of orchards across these two regions are Psa-V positive it has been combined once again into one region.

5 June 2014

Psa-V infection has been confirmed in Japan.

The disease was first found last month in the Ehime Prefecture, Japan’s largest kiwifruit production area; and soon after was confirmed in the Southern area of the Fukuoka Prefectural.

Growers in both regions have cut out all infected vines.

The Prefectural Governments together with agricultural officials and advisors are investigating the extent of the spread; and advising growers of best-practice control measures including monitoring for early detection, cutting out infected material and tool sterilisation.

Emergency financial assistance has been offered to kiwifruit growers’ for disease prevention measures.

Coromandel - regional update
5 June 2014

Coromandel harvest is now complete and most crops have achieved close to their estimate. Growers have been actively applying copper and Actigard™ post-harvest.

Psa-V symptoms have recently increased, particularly in Hort16A and Gold9 orchards.  One of the original Psa-V Gold9 sites is described as 95 percent clear of Psa-V symptoms. This follows an aggressive copper programme.

M33 males in a Gold9 orchard are expressing cane and shoot dieback. However M91 males in the same block appear to be clear of symptoms.

Growers are reporting Gold3 as clear of symptoms, except for those that were grafted onto heavily infected rootstock.

Conversion of Hort16A orchards will continue this winter. Some Hort16A growers whose orchards are not showing symptoms will continue for a 2015 crop.

Imported pollen warning
5 June 2014

A Coromandel kiwifruit grower recently received an email from California-based company Pollen Technologies, offering to supply kiwifruit pollen for artificial pollination.  It appears the pollen is sourced from either the United States or China with samples available upon request.

KVH immediately alerted MPI Imports and Exports Group (plants) of the email and contacted the Californian company to inform them that: importation of any pollen into New Zealand for plant breeding purposes is currently prohibited; the company should not solicit enquires from New Zealand; and to immediately stop all promotion of their pollen products and services in New Zealand. 

KVH included information regarding the National Psa-V Risk Management Plan’s rules and risk management around artificial pollination within New Zealand. 

MPI also contacted the supplier to confirm pollen imports are strictly prohibited. 

The company has confirmed it has not sent pollen to New Zealand and it will abide with KVH requests and not seek orders or offer samples of pollen to New Zealand kiwifruit growers.

If any growers receive any further offers of pollen or samples of pollen from a Californian, Chinese, or any overseas based company, then please alert KVH and MPI immediately.  The MPI contact should be made through the MPI exotic pest and disease hotline: 0800 80 99 66.

2014 Zespri / KVH Potted Plant Field Trial Report—Hort16A trial

This trial was established to determine the most effective time to apply Kasumin, at label rate from 14 days prior to, and up to seven days post, a Psa-V infection event. Additionally, a number of other products were tested including a copper product Ag Copp 75 and Nanospada 500. Two seaweed extracts in rotation with copper were also tested to determine if seaweed extracts could reduce phytotoxicity and Psa symptoms.

A number of conclusions were made from this trial:

  • Kasumin applied at the label rate of 100ppm one day prior to an infection event produces the greatest protection against Psa-V in Hort16A kiwifruit potted plants for up to four weeks compared with all the other application times of Kasumin tested in the trial.
     
  • Multiple applications of Nordox provided greater protection than a single application, supporting the current method of use of copper products.
     
  • Alternating applications of Nordox with seaweed extracts did not have any effect on Psa-V symptoms. The effect of the seaweed extracts in reducing phytotoxicity caused by copper was unable to be assessed as phytotoxicity was not observed during the trial.
     
  • Nanospada 500, a QAC product showed a level of Psa disease control similar to that observed with bactericides Kasumin and KeyStrepto.

KVH launches new Kiwifruit Plant Certification Scheme
29 May 2014

On 29 May Kiwifruit Vine Health launched the Kiwifruit Plant Certification Scheme (KPCS) with the release of the Core Standard (the first of two Standards under the scheme).

Nurseries can now join the KPCS and certify kiwifruit plants to the ‘Core’ Standard.  (A second ‘High Health’ Standard will be available toward the end of 2014).

This means growers will soon be able to purchase certified kiwifruit plants from participating nurseries, giving them assurance they are investing in the best possible start for their plants.  Click here to see a fact sheet for growers on the Scheme.
