Zespri has removed Kasumin® from the Crop Protection Standard (CPS) for the 2015 season while further research is done to confirm the most effective use pattern. This research is expected to confirm the optimal pre-flowering withholding period for Kasumin® and the number of applications allowed in the pre-flowering period.
Zespri has taken a conservative approach to this Psa management tool in this case, as the suite of Psa-targeted products is considered sufficient to manage Psa this season.
Growers can use up to four applications of KeyStrepto™ on producing and non-producing vines for the 2015 season, though no more than two consecutive applications are allowed without using another Psa-targeted product – e.g. copper.
Refer to the KeyStrepto™ User Guide for detailed rules of use. Growers are responsible for ensuring all use conditions are complied with. KVH no longer conducts pre-use audits.
If you have any queries please contact Gordon Skipage at Zespri.
People working on orchards at this time of year can provide extra resource for carrying out monitoring duties. Growers should be alerting their orchard workers to be on the lookout for signs of Psa-V infection, particularly cane dieback and exudate.
Don’t forget hygiene measures should be in place to prevent introduction or spread of infection between plants, rows, blocks and orchards.
The Government Industry Agreement (GIA) Secretariat visited KVH staff today to give an update on the GIA, including where other primary industries were within the process. The GIA Secretariat facilitates implementation of the partnership described in the GIA Deed and acts in the interests of all Deed Signatories.
As reported in the KVH Bulletin (22 May) the kiwifruit industry was the first to sign the GIA Deed on 20 May.
On 22 July, New Zealand Pork will be the next industry to sign the GIA Deed, representing all New Zealand pork producers.
Like the kiwifruit industry, by signing the GIA Deed, NZ Pork is recognising that biosecurity is a major risk to New Zealand pork producers and that their industry is acting responsibly in taking all possible steps to mitigate this risk.
KVH Chief Executive, Barry O’Neil, spent two days in Wellington this week discussing financial arrangements for GIA as part of a joint working group; and the development of the Operational Agreement for Fruit Fly.

Winter is an opportune time for growers to remove visible signs of infection from their orchards, including cane dieback and exudate. Ideally, growers should do this before winter pruning. Cut back 40cm from signs of infection.
Removing infection allows pruners to structure vines accordingly and minimise later potential impacts on production.
