First-hand lesson from visiting BMSB expert
30 May 2019

Experience from countries where the invasive Brown Marmorated Stink Bug (BMSB) is present is highly valuable to the kiwifruit industry, and New Zealand, in preventing and controlling any potential BMSB outbreaks.

KVH yesterday attended a Plant & Food Research-run presentation by Professor Claudio Ioriatti, a world-renowned expert on BMSB, who shared useful knowledge from the European BMSB control effort.

As Director of the Technology Transfer Centre in Italy, Professor Ioriatti has been touring New Zealand meeting with key groups involved in improving New Zealand’s readiness for BMSB. His presentation included an update on the European Union’s progress in BMSB control and outlined the general impacts of BMSB in Italy and the EU, the current situation, impacts on horticulture, and Integrated Management Strategies such as the use of netting and biocontrol options, as well as insecticides.

Information sharing like this, builds on the knowledge KVH, Zespri, MPI and the kiwifruit industry can use as we continue to formulate short and long-term plans for how we would respond to and manage a BMSB incursion on our orchards. Read the BMSB Readiness Plan (A) for information about how the industry is ready for a New Zealand incursion. Read the BMSB Readiness Plan (B) for information about long term management considerations should BMSB establish in New Zealand.

In August 2018 the New Zealand horticulture industry welcomed the Environmental Protection Authority’s (EPA) decision allowing the release of a tiny Samurai Wasp into New Zealand, if ever there was an incursion of the BMSB. Read the media release here.

Keep NZ free from stink bug winter woes
30 May 2019

We may be out of the high-risk season for Brown Marmorated Stink Bug (BMSB) but that’s no reason to stop being on the lookout.

KVH and other horticultural groups are working together again this year on keeping the BMSB profile up over the winter months. Online and social media advertising are being used to help get the message out about the lifestyle impacts of this unwanted pest, the fact it hibernates inside homes over the winter, can infest homes in the thousands and is almost impossible to get rid of.

New inflight video to educate visitors about biosecurity
30 May 2019

A new inflight biosecurity video will remind international travellers about the importance of protecting New Zealand from unwanted pests and diseases.

The video will play to arriving passengers on all airlines with screen capacity.

All visitors to the country and kiwis returning home can help protect New Zealand from harmful pests and diseases. The new in-flight video provides a clear message about what everyone’s responsibilities are when arriving here. The simple lesson is, if you're unsure about an item you’ve got – declare it.

There are two versions of the video – one spoken in English and one for Chinese airlines in Mandarin. The English version has been translated into 12 different languages, including Hindi, Malay, Arabic, Korean and French. It has also been translated into Bilsama, a national language in Vanuatu spoken by many seasonal workers.

The video is part of a wider national programme focused on protecting New Zealand and supports the biosecurity movement Ko Tātou This Is Us which highlights the personal connection we all have to the land, rivers, lakes and sea that nourish and provide for us.

Watch the English version here, or the Mandarin version here.

Tool hygiene and supervision important through pruning
30 May 2019

KVH this week visited a Gold3 orchard with multiple plants showing Psa infection symptoms both above and below autumn applied girdles.

Vines had been girdled for the first time ever in January, with the girdle re-opened in February. Copper was applied to girdles in January; in February no copper was applied, though girdles were taped to assist healing.

The pattern of infection within blocks suggested poor girdling technique and lack of tool hygiene are likely to have been factors leading to vine infection - grower survey found that for some rows, 50% of plants were affected.

This result is disappointing and a reminder that wounds are potential infection points for Psa. Research (available on the KVH website) has shown unprotected girdles can be infected for at least 15 days after the girdle is applied, and infection generally follows specific high-risk weather patterns.

Similar risk should also be considered when planning pruning rounds. As pruning commences, make sure winter rate copper is applied ahead of and after pruning. Insist on good tool hygiene and team supervision to make sure your rules are being followed.

Check the Psa risk model to help with spray and pruning planning.

Budwood registration and supply
16 May 2019

KVH best practice advice is to source budwood from your own orchard wherever possible to reduce the likelihood of spreading Psa or other pathogens.

If this is not possible, the growers who are supplying budwood off their orchard need to register annually with KVH and complete a Budwood Risk Management Plan.

Requirements for budwood suppliers are detailed in the KVH Protocol: Budwood, and include a requirement to monitor the budwood collection area and tag any vines that are showing any symptoms or are not healthy.

Budwood should not be collected from material left on the ground after pruning as this may mean that wood from unhealthy vines is distributed to other orchards, resulting in disease transfer.

It is important to maintain traceability - growers need to record all material moving off and onto their orchard. This will help with disease or pest containment in the event of a new incursion.

Movement of mature plants
16 May 2019

Growers may wish to move mature kiwifruit plants from areas where they have double planted.

The movement of plant material is considered a high-risk pathway for the transmission of unwanted organisms and therefore it is important that any such movements are given careful consideration and that appropriate measures are implemented to mitigate risk.

Please contact KVH (0800 665 825 or info@kvh.org.nz) well in advance if you wish to move any mature kiwifruit vines between properties.

Step-up in Northcote fruit fly response
16 May 2019

On Saturday it was announced another Queensland Fruit Fly (QFF) has been found within the current Northcote controlled area, bringing the total to eight over the past three and half months.

Biosecurity New Zealand is stepping up on the ground efforts in the suburb, including placing bait on fruit trees to attract and kill adult flies, in particular females. The current restrictions on the movement of fruit and vegetables remain in place and trapping and the collection of fallen fruit in some of the controlled area will continue.


While it is concerning there has been another detection, it still doesn’t tell us that there is a breeding population. What it does is raises the potential that QFF remain in the area, albeit at very low levels.

KVH continues to be closely involved in the running of the response as a member of the decision-making Governance Group, and as an industry we continue to help with on the ground activities via the KiwiNet group.

Remove unpicked kiwifruit from vines
16 May 2019

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

Unpicked fruit can increase the amount of wild kiwifruit plants establishing in nearby areas of native bush or forestry as fruit ripening over the winter months provides a food source for birds. Birds spread seed through their droppings, together with a small fertiliser package. A proportion of this seed can readily germinate.

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

Unpicked fruit needs to be dropped to the ground and mulched. This prevents mass-feeding by birds over an extended period.

Under the National Psa 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 unpicked fruit with orchard owners and post-harvest companies.

Psa protection
16 May 2019

The Psa Risk Model predicts low-risk weather for most regions into next week, providing growers with a great opportunity to apply all-important post-harvest coppers.

Where there is no risk of drift to unharvested blocks, Actigard should also be applied to strengthen protection into the leaf-fall period. Most canopies are still in good condition with ample green leaves to absorb Actigard (see image below) but the window of opportunity for this product will close as leaves deteriorate and more frosts occur.
 



Advice is to also monitor blocks for evidence of Psa and check young plants and girdled vines for evidence of Psa symptoms. Focus on more Psa prone areas of the orchard first, and mark affected vines to prompt the removal of infections through winter. Flag possible hot spot areas and use this information to create winter pruning strategies, and spring monitoring.


KVH has this week received calls from growers who are seeing red exudate on girdles indicating Psa risk is still out there. Good proactive management will minimise orchard risk going forward.
