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 .

Hydrogen Cyanamide and copper compatibility
7 August 2014

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.
