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).

NZ tightens border controls for incoming yachts
18 September 2014

New Zealand is tightening its borders by increasing scrutiny of yachts arriving in Northland this summer as a result of the two Queensland fruit fly detections in Whangarei early this year. This follows a review of how the fruit flies could have arrived in New Zealand which KVH participated in.

Eight extra quarantine inspectors will be working in Northland in ‘rummaging teams’, from October to mid-December when the bulk of yachts arrive.

MPI is also training detector dogs, working with locals, the navy and air force and contact yachties before they come to New Zealand.

KeyStrepto User Guide - new conditions of use
18 September 2014

The KeyStrepto™ User Guide has been updated with the new ACVM conditions of use. The updated User Guide and accompanying grower letter to be distributed through retailers is available on the KVH website here.

The key change is from 1 October growers must register their intent to spray KeyStrepto™ on the Zespri Canopy or KVH website and orchards may be subject to random audits. The online function will be available from 1 October. Before 1 October, you do not have to register intent online but all requirements and best practices must be followed. Refer to the KeyStrepto™ User Guide, including a Site Inspection Record.

While some of the conditions of use have changed, the responsibility to minimise nectar-bearing flowers such as buttercup and clover is unchanged from previous years.

Other conditions of use

  • KeyStrepto™ is permitted for use on kiwifruit orchards in the North Island only.
  • A maximum of four applications of KeyStrepto™ can be applied each season from 14 June to one week before the first kiwifruit flower opens on the orchard.
  • To prevent resistance developing, you cannot apply more than two consecutive applications of KeyStrepto™ before applying an alternative registered Psa-V product such as copper and Actigard™.
  • Notify neighbours preferably 48 hours before spraying – but at least 12 hours before.
  • Use AI nozzles and drift-reducing surfactants for early-season spraying.
  • A tank mix of KeyStrepto™ and copper is acceptable on the third application of KeyStrepto™.
  • Ensure open flowers in the sward and shelter are kept to an absolute minimum.

Refer to the KeyStrepto™ User Guide for detailed rules of use. Growers are responsible for ensuring all use conditions are complied with.

The 2014 Operational Plan was approved by the KVH Board, and sent to the Minister today to ensure he is satisfied it is consistent with the NPMP. This follows a period where growers had the opportunity to provide feedback on the Plan. However no feedback was received.

The Operational Plan serves as a business plan that will be reported against and revised on an annual basis.

KeyStrepto use - 2014 conditions update
11 September 2014

The current use conditions for KeyStrepto™ require growers to read and comply with the KeyStrepto™ User Guide and complete a Site Inspection Record before application. These will be provided by your retailer at point of sale and will be available on the KVH website here.

From Wednesday 1 October, to allay the concerns of bee keepers and mitigate residues on kiwifruit at harvest, growers will be required to register their intent to spray KeyStrepto™. 

This will be done via an online tool which will be accessible from the KVH website, Zespri Canopy and AgFirst’s website. Information about how to access the tool will be provided once confirmed.

AgFirst will conduct random audits on behalf of the industry to ensure use conditions are being met.

Orchards that fail to meet these requirements will be subject to future audits and the normal penalties imposed under Global GAP and the Zespri Crop Protection Standard.

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
