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.

Crop Safety of Late Leaf Fall Copper Applications on Gold3—by HortEvaluation

A study was undertaken to determine whether copper applied with a superspreader or a penetrant adjuvant at late leaf fall causes phytotoxicity to buds. A second objective of this project was to evaluate efficacy for Psa disease control.

Draft 2014 Operational Plan - consultation
24 July 2014

KVH prepares an Operational Plan for the National Psa-V Pest Management Plan (NPMP) on an annual basis. This sets out how the NPMP will be implemented over the year ahead. It includes the KVH Board’s NPMP strategy, policies that guide how KVH will make decisions, the approach KVH will apply to achieve the NPMP objectives and budget and performance measures against which outcomes can be judged.

KVH must submit the Operational Plan to the Minister for Primary Industries, who checks it for consistency with the NPMP and is able to disallow all or parts of it should there be inconsistencies. 

While not a statutory requirement, KVH is seeking any feedback on the Draft 2014 Operational Plan over the next three weeks. Please send any feedback to KVH by 5pm on Friday 15 August 2014. You can email your feedback to info@kvh.org.nz or post to PO Box 4246, Mount Maunganui 3149.

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.

Rapid commercialisation of an integrated, biologically based management package for Psa-V

A follow up project aimed at validating the field efficacy of Trichoderma and Yeast Mix and determining the compatibility of the two yeast strains with a copper-based product. Also, to identify a suitable manufacturer of Trichoderma and Yeast Mix and a distribution partner in New Zealand in order to facilitate a ‘fast tracking’ process that would move both prototype BCAs towards commercialisation as quickly as possible, on the condition that significant disease reductions were achieved in field studies.

KeyStrepto/Copper resistance testing
17 July 2014

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.

Hail netting installation on the increase
17 July 2014

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.
