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

Click here to read the report and see the matrix that was used to identify these organisms.

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.
