Biocontrol defence against BMSB: last chance to have your say
17 May 2018

The Brown Marmorated Stink Bug (BMSB) is one of the biggest biosecurity threats we face and it could cause hundreds of millions of dollars of losses. If an incursion is found here the consequences would be disastrous for New Zealand’s horticultural industries.

The Samurai Wasp (which is the size of a pinhead and doesn’t sting humans or animals) provides an opportunity to be proactive in our approach and gives us another tool we can use to control BMSB.

KVH, other horticultural groups and the Ministry for Primary Industries (MPI), have made an application to the Enviornmental Protection Authority (EPA) seeking approval to release the wasp as a biocontrol agent against BMSB, but only if an incursion is found in New Zealand.

The EPA is currently seeking public opinion on the application and you have until 5pm Thursday 31 May 2018 to make a submission.

KVH is making a submission on behalf of the kiwifruit industry and your views count too. We encourage growers to have a say and we can make available to you a copy of the KVH submission that you may wish to reference content from when making your own submission to the EPA (or use the template we've created to help with this).

If you have any questions you can email us at info@kvh.org.nz or phone us on 0800 665 825.

Monitor and remove Psa to protect next crop
17 May 2018

Autumn is here and new active cankers with exudate have been found on orchards in several regions over recent weeks. 

For growers who have completed harvest, now is a good time to complete a round of Psa monitoring to identify areas where you may need to modify your pruning strategy to ensure as much Psa as possible is removed from the canopy.  Look for cane and leader dieback and fresh exudate. Any large active cankers are likely to worsen before spring, so consider removing these before you send the pruners in.

Autumn spray programmes should include regular copper application at full winter rates and if possible at least one Actigard where leaf is fully functioning.  Actigard can be tank mixed with copper and is most effective when applied to leaves that are still in good condition. Extreme care must be taken to avoid spray drift onto unharvested blocks. After spraying Actigard ensure that spray tanks, lines and nozzles are cleaned thoroughly before spraying other products on unharvested fruit.

For more information, refer to KVH's Psa Best Practice Guide and the latest Actigard technote.

To maintain a high level of on-orchard hygiene, growers should continue to monitor pruning staff and ensure tool hygiene at all times. Restrict access to unnecessary vehicles. Best practice guides are available on the KVH website.

Summer summary: everyone on the lookout for BMSB
17 May 2018

Every New Zealander has a role to play in managing the risk of Brown Marmorated Stink Bug (BMSB).

KVH co-funded a nationwide summer BMSB education campaign with the Ministry for Primary Industries (MPI) and other horticultural sectors to lift public awareness around the damaging impacts of the pest and increase the likelihood of early detection through surveillance.



The results of the summer campaign are in:

•    There were 931 calls to the MPI biosecurity hotline (more than double last year).
•    Website ads generated the most calls to the hotline.
•    There were over 6.5 million views of our online ads.
•    The Metservice weather app ad was by far the most viewed of all our ads.
•    Just over 30,500 visitors to the BMSB page on the MPI website (12500 more than last year).
•    Ruud ‘the Bug Man’ Kleinpaste posts and videos were the most effective social media tools.
•    There was a lot of news media interest in BMSB, especially around the turned away ships in Auckland and the Samurai Wasp as a biocontrol. The morning after a KVH story about BMSB aired on the One News 6pm show in late August, MPI received 15 calls about suspect bugs from people who had seen the clip.

Partnerships were also a big focus of the campaign. KVH worked across the kiwifruit industry to talk about BMSB and distribute information. Some initiatives were:

•    New posters, fliers and stickers distributed to packhouses, transitional facilities, and vehicle importers.
•    Information sent to all members of NZ Plant Producers Inc, including nurseries and Mitre 10 stores.
•    Posters and leaflets distributed through PGG Wrightson and Fruitfed suppliers.
•    Hospitality NZ helped communicate the BMSB threat through their newsletters and social media.
•    Allied Pickfords transport put messages on trucks and in warehouses/depots.
•    The Port of Tauranga Biosecurity Excellence partnership focussed on BMSB during the local biosecurity week with staff who work on and around the port.

Conference raises Xylella awareness
17 May 2018

Last week KVH attended the Better Border Biosecurity (B3) conference in Wellington.  B3 is a joint venture for plant biosecurity science in New Zealand integrating expertise and investment from several Crown Research Institutes, and end users such as the Ministry for Primary Industries (MPI) and industry.

In addition to profiling research into new, smarter biosecurity tools such as remote sensors and advanced diagnostics, the conference had an underlying theme of building collaboration to achieve better biosecurity. This includes working alongside Australia more, as they are our closest parallel in the biosecurity sense being an isolated South Pacific nation with similar challenges and pressures, but also present our greatest risk given how near and connected our countries are.

At a more local level, collaboration includes building biosecurity excellence in local communities and the conference featured a presentation by John Kean on the science that is being developed to support regional initiatives for biosecurity excellence in port communities.

A presentation that caught everyone’s attention was the keynote talk from Professor Alexander Purcell (Berkeley College, USA) on the biosecurity threat of Xylella fastidiosa to New Zealand.

X. fastidiosa is a bacterium that has caused severe impacts to the Californian wine industry and is currently decimating the Italian olive industry, killing over a million olive trees. Kiwifruit is not a known host however Dr Purcell provided an insight into the complexities associated with this pathogen and discussed the wide range of strains affecting different plants. Although the true host range of all strains is currently impossible to predict or test, MPI and industry groups for other horticultural products that are known hosts to this pathogen have had it on their radar for many years, as have Australia.

The presentation and workshop following the conference provided an opportunity to advance preparedness for X. fastidiosa and identify where to focus our efforts. For example, it’s spread through Europe has highlighted the importance of biosecurity controls on plant material movements before pathogens are detected.

X. fastidiosa took some time to diagnose, and continues to be debated, as it spreads through Europe. It has now been detected in France and Spain, which produces half of the world’s olive oil.

Dr Purcell suggests that the number of different strains present in these European regions could mean Xylella has been introduced on more than one occasion. Biosecurity practices and traceability reduce the likelihood of spreading such pathogens and provide a far better chance of containment or eradication should they arrive here at all.

BMSB expertise from Chile
17 May 2018

Last Thursday KVH and New Zealand Avocado hosted a discussion about Brown Marmorated Stink Bug (BMSB) with Ilania Astorga from Servicio Agricola y Ganadero, the Chilean equivalent of our Ministry for Primary Industries (MPI).

Iliania was invited to New Zealand by the BMSB Council (a partnership between horticultural industry groups and MPI) and also presented at the two-day Better Border Biosecurity conference earlier in the week.

Attended by biosecurity experts, industry representatives and scientists from across the region, the discussion focused on where and when BMSB has been found since the bug was first detected in urban Santiago (the Chilean reponse is still confined to an urban environment). Initiatives currently underway to manage it, including survellaince and trapping activities were also discussed.

There was also a Q&A session during the presentation to learn more about the opportunities and challenges faced by the Chileans and how these can help shape New Zealands response plans. 

For example, BMSB is capable of flying up to 100k a day but the Chilean experience is that the bugs don’t move much, or very far in distance, which may be due to the large number of preferred host trees in the city and the fact that bugs don’t need to travel far to get the food and nutrients needed.



This discussion with Ilania built on the learnings of an ‘NZ Inc’ group - including KVH - that visited Chile late last year to assist in the response. Read more about that trip
here. This relationshop provides an excellent opportunity for New Zealand to learn from Chile’s experience and assist to mitigate the risk of entry to New Zealand, and refine our own response tools and strategies.

Unwanted!
17 May 2018

Each month we profile one of the 12 most unwanted pests featured on our ‘Port of Tauranga – committed to biosecurity excellence’ calendar. Any of these pests could potentially enter our borders and have a major impact on local community and businesses, the kiwifruit industry or other local growers. Profiling these pests and raising public awareness increases the chances of early detection, should an incursion occur.

This month the focus is a significant threat to the avocado industry, the Shot Hole Borer. These are small beetles that are a destructive pest of forest trees and attack fruit, shade and ornamental trees.


Originating in Southeast Asia, this invasive beetle is now causing significant impacts throughout California’s avocado industry where adult females tunnel into trees to lay eggs and grow fungus, which spreads and attacks tree tissue. Initial infection is followed by wilting of branches and discolouration of leaves, and then the collapse of heavy branches.

The pest is particularly attracted to injured or stressed trees - look out for any damage caused by wood-boring beetles, especially entry/exit holes surrounded by wet discoloration or white exudate. The beetle’s holes penetrate 1-4cm into the wood.

Shot Hole Borer beetles fly from tree to tree, but can cover considerable distances. Spread is through plant, equipment, and wood movements.

The new Biosecurity New Zealand
3 May 2018

KVH attended the launch of Biosecurity New Zealand earlier this week.

It is one of four new business units created within the Ministry for Primary Industries (MPI) to provide a stronger focus on key areas of work.

At the launch, Minister for Biosecurity Damien O’Connor said pest incursions and disease outbreaks threaten our biodiversity and with increasing pressures such as growing trade, more visitors from abroad, and climate change challenges, we need a greater focus on biosecurity.

KVH works closely with MPI and advocates strongly for the kiwifruit industry in the development of legislation, policies, and standards; and in readiness and response planning. We look forward to continuing this working relationship with what is now a single point of accountability and leadership.

We particularly note the Ministers comments that the change brings together some 900 MPI staff which we agree will help provide the resources and people-power (alongside industry groups like KVH) to protect our country from biosecurity threats and respond quickly to any outbreaks.

In addition, a 25-strong biosecurity intelligence unit has been announced, which will track dangerous insects here and overseas and prepare this country’s defences in advance. This aligns with the work KVH has been leading on behalf of the kiwifruit industry to ensure preparedness for incursions from the likes of the Brown Marmorated Stink Bug (BMSB) and fruit flies and provides more resource and knowledge that we can tap into.

Last chance for submissions: importing Actinidia plants
3 May 2018

Growers have until 5pm Friday (tomorrow) to provide feedback to the Ministry for Primary Industries (MPI) on the proposed Import Health Standard for Actinidia plants for planting.

The Standard sets out the proposed import requirements for Actinidia nursery stock, specifically for plants in vitro (tissue culture), imported into New Zealand for further propagation. This pathway has not been active since 2013 because of the Psa incursion.

KVH is making a submission on behalf of the industry and as part of that we’re engaging with experts in the science community in New Zealand and internationally to ensure we have specific technical advice available on the risks of what is being proposed. We’ll keep you fully informed before any decisions are made on the outcome of this pathway.

KVH recognises the importation of new kiwifruit material is an important component in maintaining the competitive advantage of our industry, however the risk of introducing new biosecurity threats must be carefully managed and this is the focus of our submission. Tissue culture is regarded as the most promising process for producing clean material and provides the opportunity for verification measures to be included in the production process to ensure risks are managed to an acceptable level.

Information about how to submit feedback is available on the MPI website - the consultation package includes information about the risk organisms that could potentially be transmitted on this pathway, and the proposed measures to mitigate this risk.

If you have any questions about the submission process or content for your own submission, please contact us at info@kvh.org.nz or phone us on 0800 665 825.

Applying copper after harvest
3 May 2018

It is highly recommended growers apply copper immediately after harvest, with full winter rates as per the KVH Recommended Product List providing maximum protection of fruit stalk and leaf scars from Psa.

Studies suggest movement of product into fruit stalk scars occurs much more readily immediately after harvest versus sprays applied a week later.

Where leaf condition is good and risk of spray drift to unharvested fruit is managed, Actigard can be tank-mixed with copper to provide a dual mode of protection as further leaves fall.  Botryzen and the soil root drench KiwiVax (both products with BioGro registration) can also provide benefits, particularly in lower Psa risk situations.

The KVH Psa Risk Model shows moderate risk for most kiwifruit areas through next week and recent leaf spotting seen on outside rows of some Hayward kiwifruit blocks provides evidence that innoculum levels are on the rise. Similarly, cane dieback and cankers in harvested gold blocks indicate potential reservoirs of infection.

Moving budwood
3 May 2018

Budwood movement will be a focus for many suppliers and growers at this time of year, particularly those cutting over to new licences and those with new plantings.

As budwood poses the highest risk of disease transfer, please remember:

·       Use the cleanest source of budwood, from your own orchard where possible.

·       Budwood suppliers must be registered with KVH and supply a copy of their Psa-V Risk Management Plan.

·       Growers must only obtain budwood from a KVH-registered supplier.

·       Budwood movement must comply with the controls outlined in the KVH Protocol: Budwood.

·       Movement of Gold3 budwood also requires Zespri authorisation.

·       Budwood movements from Psa positive orchards to other Psa positive orchards are only allowed between properties owned by the same legal entity within the same Psa region (defined on KVH website maps). Outside of this, KVH authorisation may be sought if there are no other suitable options for the grower. Contact KVH for permission in these circumstances.

·       Budwood collection areas are to be sprayed with copper within four weeks of collection.

·       Maintain tool hygiene and sanitisation.

·       Records of budwood supplied and received must be maintained and kept with grower GAP records.

If you are unsure of the movement controls or have any queries, please contact KVH on 0800 665 825 or email info@kvh.org.nz.
