Autumn brings reports of Psa-V
30 May 2016

With autumn weather firmly settled in, reports of Psa-V symptoms are on the rise in some orchards. Mostly from sites where the disease has been challenging in the past.

Autumn observations:

  • Young Gold3 scions girdled in early March were showing exudate at the girdle points. Infection in the trunks and leaders were also common in these plants.
  • Exudate from trunk lenticels on young scions.
  • A Gold3 block, which recovered strongly after ongoing spring cut-out of Psa-V, showed indications of infection beginning to move back through some plants. Symptoms included dieback from leader cut points, dehydrated strung laterals and blackened canes.
  • New spotting was seen on Bruno suckers and/or young plants, particularly where a comprehensive spray programme had not been maintained.
  • On some Gold3 blocks, cane die-back and fruit shrivel was seen during harvest.

Recommendations:

  • Monitor orchard areas where Psa-V infection has been present in the past and remove infected material as soon as possible.  Removal and disposal of infected material outside the production area remains a key tool in Psa-V management and a key component of the industry management strategy to minimise the build-up and spread of any resistant Psa strains that may have developed.
  • Maintain excellent tool hygiene and protect pruning cuts to avoid infection transfer.
  • Trim high male growth, particularly in sites prone to frost. Warm temperatures have led to growth flushes, creating tissue that will be vulnerable to frost damage and Psa-V infection when temperatures turn colder.

KVH hosts MPI staff
19 May 2016

Last week KVH hosted twenty-three visitors from MPI’s surveillance and incursion investigation teams from Wellington. The purpose of the visit was for MPI staff who are directly involved in incursion responses to gain both a better understanding of the kiwifruit industry and an overview of the work KVH is doing around biosecurity.

The group visited Trevelyan’s Pack and Cool to observe packing and coolstore operations; and Plant and Food Research where they were updated on kiwifruit research by Dr Stuart Kay.

After a busy morning in Te Puke they were presented with Zespri’s industry overview and future strategy by Carol Ward.

KVH highlighted its ongoing biosecurity initiatives and discussed partnerships with the regional councils, ports, freight and logistics sectors to raise biosecurity awareness amongst these sectors.

The tour also provided a good opportunity to discuss future possibilities about how industry and MPI can work together under GIA on biosecurity challenges.

Speaker of the House visits KVH
19 May 2016

The Hon David Carter visited KVH last week to get an overview on how the industry is managing Psa-V and to observe how prepared we are for a future biosecurity incursion.

David Carter was Minister of Biosecurity in 2010 when Psa-V arrived in New Zealand and supported the industry with $25 million of government funding, which was matched with industry funding, and enabled the industry to rapidly respond and begin the long road to recovery from Psa-V.

After being briefed on what KVH is doing to support the industry from biosecurity incursions, along with the current approach to Psa-V management, he visited an orchard to better understand the current state of the industry.

He was very complementary about how far the industry has progressed since 2010, and the work that is being done to protect the industry from biosecurity threats into the future.

Growers looking for rootstock
19 May 2016

Around this time each year a number of growers are trying to source kiwifruit plants at the last minute, which can be a difficult task as many nurseries have sold out.

KVH is aware of some nurseries that have plants remaining, therefore, growers looking for plants, or other nurseries with plants remaining, can contact KVH at info@kvh.org.nz and we can endeavour to connect the parties.

Growers are advised to order plants a year in advance to prevent being caught in this situation.

KVH signs Operational Agreement for fruit flies
19 May 2016

On 9 May 2016 Kiwifruit Vine Health (KVH) signed the Operational Agreement (OA) for fruit flies on behalf of the kiwifruit industry—a significant milestone to further improve biosecurity readiness and response activities for fruit flies and the first such agreement under the Government Industry Agreements (GIA) partnership.

GIA partners, The Ministry for Primary Industries (MPI), Pipfruit NZ, NZ Citrus Growers and NZ Avocados are also signatories of the OA.

The OA sets out the operational requirements for readiness and response activities for fruit flies and importantly, enables joint decision making and also clarifies cost-sharing arrangements between government and affected industries.

Under the OA, KVH and other parties will agree a work plan to improve readiness and response, including how we can detect fruit flies earlier and also reducing costs without reducing effectiveness.

Cost-sharing for fruit fly readiness and response activities commences when the OA comes into full effect in 2017. Once fully implemented, the Government will pay the first 20% of total costs on behalf of risk exacerbators. The remaining costs will then be shared by government and benefiting industries as follows:

  • 70% Govt: 30% Industry for readiness/surveillance (current annual costs are around $1.85m)
  • 70% Govt: 30% Industry for level 1 response (i.e. Whangarei response)
  • 80% Govt: 20% Industry for level 2 response (i.e. Grey Lynn response)
  • 90% Govt: 10% Industry for level 3 response (larger response where alternative control methods may be required.

The industry portion will then be divided among all benefiting industries based on industry value. For a fruit fly incursion, the kiwifruit industry currently represents about 48.5% of the value of all industries potentially affected by this organism, and therefore would pick up 48.5% of the total industry share.

Costs are limited by a fiscal cap which equates to about $3.12m for the collective industry share. The existing kiwifruit biosecurity levy paid by growers is sufficient to cover kiwifruit industry costs under the OA.

Industries that benefit from a response but haven’t signed up to GIA or the OA will still have to pay their share and the government will seek to recover costs from 1 July 2017.

Developing tools to detect Pelargonium zonate spot virus
19 May 2016

The kiwifruit industry is funding a project that will provide tools to detect Pelargonium zonate spot virus (PZSV) should it arrive in New Zealand.

PZSV is one of only two viruses known to induce severe symptoms in kiwifruit. This virus is widely distributed in many species but has only been reported in kiwifruit in Italy. It has not been reported in New Zealand.

Permission is being sought from MPI to import freeze-dried tissue containing PZSV and its use as reference material (positive control) to evaluate a molecular test for detection of the virus. The test would be used for the benefit of the industry by testing incoming material and providing a tool for rapid testing should we be faced with an incursion of this organism.

Any risks involved in this would be very carefully managed.

Remove unpicked kiwifruit from vines
19 May 2016

Growers are reminded that unpicked kiwifruit must be removed from vines by 1 July.

Unpicked fruit can greatly exacerbate the amount of wild kiwifruit plants establishing in nearby areas of native bush or exotic forestry, as fruit ripening over winter months provides a food source for birds such as white-eyes. 

Birds spread the seed through their droppings, together with a small fertiliser package, and a proportion of this seed can readily germinate. 

Between 2002 and 2012 contractors controlled an average of 11,000 wild vines per year in the Bay of Plenty region.

Unmanaged kiwifruit vines, including those with unpicked fruit, may also be a potential host for plant disease organisms.

There may be an increased amount of unharvested kiwifruit this season if fruit fails to meet industry export standards.

Unpicked fruit needs to be dropped to the ground and mulched.

Under the National Psa-V Pest Management Plan (NPMP) it is a requirement to remove all unpicked fruit from vines by 1 July each year.  After this date KVH will follow-up reports of orchards with unpicked fruit with the orchard owners and post-harvest companies.

Hill Laboratories - change to frequency of routine Psa testing
19 May 2016

Due to a decline in the industry’s demand for rapid Psa testing, Hill Laboratories have advised it is no longer providing Psa testing and results within 48 hours.

From 23 May 2016 they will run the Psa testing once a week—every Wednesday. Results will be reported the following day, providing no repeat testing is required. The testing cost will remain the same.

However, in cases where time is critical and there is a requirement to turn around a rapid result within 48 hours, they can provide this service with a 50% price increase.

Please note—any KVH-funded urgent testing will now need to be authorised by KVH prior to samples being submitted.

Kiwifruit industry to sign Operational Agreement for fruit flies
5 May 2016
Next week Kiwifruit Vine Health is expected to sign the Operational Agreement (OA) for fruit flies on behalf of New Zealand’s kiwifruit industry.
 
This will be the first such agreement under the Government Industry Agreements (GIA) partnership and will help to further reduce the impacts of fruit flies to our horticulture sectors.
 
KVH Chief Executive Barry O’Neil explains the benefits of the OA for fruit flies.
 
“Signing the Operational Agreement is a significant milestone that will see GIA Deed signatories working together to help reduce the impacts of fruit fly.
 
“Essentially, the OA sets out the operational requirements for readiness and response activities for the four economically significant species of fruit flies (Queensland Fruit Fly, Mediterranean Fruit Fly, Oriental Fruit Fly and Melon Fruit Fly) and cost-sharing arrangements between Government and affected industries.
 
“Under the OA, KVH and other parties will agree a work plan to improve readiness and response, including reducing costs without reducing effectiveness.
 
“Being the first agreement of its type, it will set the platform for future OAs to be developed for other pests and diseases that can harm our horticultural industries.
 
“Fruit flies are the biggest biosecurity risk to the kiwifruit industry, in terms of both production and market access impacts. We’ve learnt that working together with Government and other affected industries provides a far better outcome during readiness and response activities. Signing the OA ensures joint decision-making and clarifies roles and responsibilities so all parties benefit.”
