Kicking up a stink over another unwanted pest
31 July 2014

In the past 15 years, several dozen brown marmorated stink bugs have been intercepted at the New Zealand border, usually hailing from the United States, although the pest is native to China, Korea, Japan and Taiwan rather than the Americas.

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.

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.

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.

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.
