Forevergreen Seedlings joins KPCS
2 June 2016

Forevergreen Seedlings has joined the Kiwifruit Plant Certification Scheme (KPCS) and is the third nursery selling KPCS-certified plants in the Tauranga region. Forevergreen sells containerised plants grown undercover and is located in Te Puna.

Nine nurseries have now joined the KPCS and are supplying certified plants, demonstrating they are managing biosecurity risks, have been independently audited, visually inspected for target organisms and returned a non-detected result for a very comprehensive testing regime for Psa-V.

Three other nurseries are in the final stages of becoming part of the Scheme. Click here for a list of nurseries and their status.

Nurseries cannot produce plants they may not have a market for. Therefore, growers are reminded to place their orders at least a year in advance, as many nurseries have sold out this year. If you are having difficulty in sourcing plants please contact KVH on 0800 665 825.

KVH movement controls apply to all plant movements. See KVH Protocol: Nursery Stock.

Evaluating tools for detection of Pectobacterium carotovorum subsp. actinidae
2 June 2016

The New Zealand kiwifruit industry is funding work to evaluate existing diagnostics for the biosecurity risk organism Pectobacterium carotovorum subsp. Actinidae, a bacterium that is reported to cause summer cankers in kiwifruit plants in South Korea.

Cultures of this regulated organism have been transferred from the International Collection of Microbes from Plants (held at Landcare Research) to perform evaluations of the diagnostics at The New Zealand Institute for Plant & Food Research’s approved physical containment facilities at Lincoln.

Any risks involved in this work are being mitigated by performing experiments under strict containment standards, which are enforced by MPI and the Environmental Risk Management Authority.

Validated tests will 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.

Port of Tauranga biosecurity operational excellence
2 June 2016

Last week KVH met with other steering group members for the third meeting of the Port of Tauranga Biosecurity Operational Excellence initiative.

The Ministry for Primary Industries (MPI) presented a risk profile analysis on Port of Tauranga (POTL), identifying the pests most commonly intercepted through this pathway to help the initiative target its efforts on these pests.

The group also agreed to develop performance monitoring criteria to support effectiveness of activities. 

Research providers from the National Science Challenge, B3 (Better Border Biosecurity) and Scion presented initial proposals on how science could help improve biosecurity effectiveness at the POT.

The next steering group meeting is scheduled for October.

Have you seen (or heard) this bird?
27 May 2016

The Red vented bulbul is an unwanted pest in New Zealand. While MPI has confirmed reports a number of these birds are present in the wider Auckland area, one was recently found in Te Puke.

An observant resident recognised its distinct bird call and immediately contacted the MPI exotic pest and disease hotline. A DOC ranger was subsequently deployed and was able to identify and destroy the bird.

Native to Pakistan and Southwest China, the Red vented Bulbul has established in a number of Pacific Islands. Evidence suggests they spread to new land masses on board sea vessels which may be how these birds have got here.

The Red-vented bulbul is an aggressive bird known to cause significant damage to fruit and vegetable crops and attack other birds.

Description:

  • Small–medium sized bird (larger than a sparrow, but smaller than a blackbird)
  • Approximately 20 cm in length
  • Dark brown/black in colour with a light coloured belly and the distinctive crimson-red patch beneath the tail.
  • Head is black with a small peaked crest.

Click here for a fact sheet where you can listen to its call.

If you think you have seen or heard the Red vented bulbul, or any other unusual pest or disease, please contact the MPI exotic pest and disease hotline on 0800 665 825.

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.

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.

Autumn brings reports of Psa-V
19 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.
