Keep up with biosecurity when replacing plants or planting new blocks
28 May 2020

Winter is the time when growers look to replace plants on their orchards or plant new blocks. This article is a reminder that if these plants are being moved between properties there are biosecurity requirements that must be met to reduce the likelihood of spreading pests and diseases including Psa.

As a general rule, plants may only be sourced from nurseries that meet the requirements of the Kiwifruit Plant Certification Scheme (KPCS). There are two types of these nurseries – both are listed on the KVH website.

1.      Full certification plants: these are plants that are free of Psa and other target organisms. Nurseries with these plants have demonstrated the ability to keep Psa out of their growing environment (either through growing in a fully enclosed greenhouse or by being located in an Exclusion region where there is no Psa) and plants have tested Psa Not Detected. 

2.      Restricted certification plants: these are plants that may have the common New Zealand form of Psa (Psa-V) but are free of non-New Zealand and resistant strains of Psa.

The only exception is Grow for Your Own Use, where plants are being grown for use on another property (or properties) under the same ownership within the same Psa region. In this case up to 1000 plants per year can be moved between these properties. Growers using this option must register with KVH and submit a KVH Psa-V Risk Management Plan - Growing Rootstock for your own use.

Plants displaying symptoms are not to be moved and both the nursery and recipient are to maintain traceability records should symptoms develop at a later stage and tracing be required.   

Please contact KVH on 0800 665 825 if you would like more information about the requirements.

Colder temperatures bring higher Psa risk
28 May 2020

Recent cold snaps in most regions have brought welcome winter chill and a good start to leaf drop, but there are also reminders that autumn conditions heighten Psa risk.

For some Waikato orchards -5 degree frosts were recorded last week, and on Psa challenged blocks this sudden dip in temperature has triggered Psa expression. Exudate from girdles and older cankers flag the need to get winter coppers on to rebuild protection after many months of no sprays. Young plants can also come under pressure during cold periods as described in a recent KVH unusual symptoms report.

Development blocks exposed to frosts or wind need special attention as younger growth remains vulnerable to injury, providing opportunity for Psa entry. Good autumn protection is an important part of year-round management of this disease. Forecast risk of ground frosts can be accessed through the KVH Weather & Disease Portal.

Stink bug in tech winners' sights
28 May 2020

KVH Chief Executive Stu Hutchings was part of the judging panel at this year’s Ag Tech Hackathon, where an innovation and technology company with a track record for coming up with high-tech solutions to industry problems claimed the win for their device that has the Brown Marmorated Stink Bug (BMSB) in its sights.

Their solution, Bugkilla, uses pheromones and light waves to attract BMSB into a chamber. The bug crawls in and a camera identifies if it is a stink bug. If it is, a fan draws the bug up to an electric grating and zaps it then ejects the dead bug.

Farmers Weekly spoke to the winners about their win in the Zespri-funded project, and next steps – which may include KVH as an end-user of potential products that help with the management of this pest, one of the kiwifruit industry’s most unwanted.

Scientific research publications that drive KVH policies and management advice are added to our website as they are finalised. Growers are encouraged to look them up and have a browse of the many different reports we make available.

The following reports have recently been added to the KVH website:

Cold temperature and frost effects on Psa: This three year project investigated the role of cold temperature and frosts in exacerbating Psa infection in New Zealand kiwifruit orchards. Observations included pre and post frost inoculation of detached canes (HW and Gold3), potted plants exposed to natural frost (HW and Gold3), and potted plants exposed to simulated frost (Gold3 only).

Findings from the work suggest that protecting dormant canes in response to mild frosts (for example by frost protection and/or copper applications) is not necessary, but for frosts below -6 degrees, copper application might reduce Psa infection and it doesn’t matter whether the copper is applied just before or just after a frost event.

Yellow Spotted Stink Bug (YSSB) literature review: Chinese and English databases have been used to source and review publications about YSSB and kiwifruit. The report describes the lifecycle of YSSB, its impacts on kiwifruit and other crops, and potential control options.

Psa biovars literature review: The taxonomy of Psa has been evolving rapidly in recent years. This report reviews the nomenclature associated with Psa and the virulence of different biovars. The ability of a few strains of different biovars to multiply on or in kiwifruit tissues has been reported but as of today there is no study which demonstrates that strains of some biovars are more virulent than others.

Remove unpicked kiwifruit from vines
28 May 2020

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 such as white-eyes. 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 as soon as possible. This prevents mass-feeding by birds over the entire winter period. It may be necessary to rake the fruit out from beneath leaders to that the mower can mulch all of the fruit.

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.

Movement of mature plants
14 May 2020

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 biosecurity 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.

BMSB awareness campaign proves its worth
14 May 2020

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

During the most recent high-risk season (September 2019 through to April 2020) KVH co-funded a nationwide summer BMSB education campaign with Biosecurity New Zealand 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 a record number of calls to the Biosecurity New Zealand hotline (1415 calls compared to 937 the season prior).

       Website ads generated the most calls to the hotline.

       There were over 11 million views of our online ads on websites like MetService, Stuff.co.nz, TVNZ and TV3 websites.

       Just under 45,000 visits to the BMSB pages on the Biosecurity New Zealand website.

       Extra awareness activities at international airports resulted in over 130 calls from travellers reporting suspected BMSB in luggage.

       Social media advertising, videos and posts were seen by more than 14 million people.

       Ruud ‘the Bug Man’ Kleinpaste posts and videos were the most effective social media tools.

       February recorded the highest ever number of calls to the pest hotline (323), most of which were attributed to the paid stories on two consecutive nights on the Newshub 6pm news by The Aotearoa Science Agency.

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

       Posters, fliers, stickers, and videos shared with growers, pack-houses, transitional facilities, schools, and community groups.

       Tauranga Moana Biosecurity Capital focused on BMSB, especially with the large banner on the Grain Corp tanks on Hewletts Road near the Port of Tauranga.

       The Port of Tauranga Biosecurity Excellence partnership focussed on BMSB during the local biosecurity week with staff who work on and around the port. Calendars, playing cards, key rings and pest alerts were distributed.

       All Auckland International Airport staff supplied with BMSB ID lanyard cards that were worn with security cards so any hitchhiking pests could be identified in the airport environment.

Next years campaign will target the wider public again because that is what keeps resulting in high call numbers and high ‘click throughs’ to more detailed information online. Digital/online advertising will continue to be used because we know that people are watching our ads/videos through until the end and are then ringing the pest hotline or visiting official BMSB web pages. It’s also a far-reaching medium that is very cost effective.

Partnerships with the kiwifruit industry through KVH, Tauranga Moana Biosecurity Capital and the Port of Tauranga Excellence programme will continue as they are all working well and generate interest and calls, as well as keeping BMSB top of mind for key audiences.

The artwork and design of the BMSB campaign (the blue NZ maps) has been surveyed and found to be well liked, and results in people carrying out the desired behaviour of knowing what to look for and how to make a report. It isn’t always well recognised over the long-term though, so a revamp will be considered for the 2020/21 BMSB season.

Express freight survey shows low biosecurity risk
14 May 2020

A recent Biosecurity New Zealand survey shows risk from express freight is being well managed.

Carried out from December 2019 to February 2020, the survey found express freight items arriving in New Zealand were almost 100% (99.996%) compliant with biosecurity requirements.

Express freight is air cargo that has guaranteed delivery times and is often delivered directly to the door.

The survey was prompted by an independent review of passenger and mail services last year, which recommended Biosecurity New Zealand test the assumption that express freight is low risk.

Electronic import documents are currently screened to identify anything that needs to be examined further, however the survey suggested further work to ensure the actual contents of parcels match what is declared. As a result, Biosecurity New Zealand says it will look at ways to beef up verification, including ongoing surveys, screening with mobile x-ray machines and increased use of detector dogs.

The survey involved examining nearly 2500 parcels across five express freight companies.

BOTRY-Zen now has a full claim against Psa
14 May 2020

The biological BOTRY-Zen now holds a full registration through ACVM as a biological control option for Psa.

A limited label claim was initially achieved in 2013. Plant & Food Research is the research provider for Botry-Zen (2001) Ltd and has carried out field trials that have contributed to ACVM granting label claims for the product, for the control of Psa in kiwifruit.

BOTRY-Zen holds certified Biogro status and offers an additional control option for all growers.  It is best used as part of an integrated control programme and is better suited to low Psa pressure situations. The product contains Ulocladium oudemansii U3 spores as the active ingredient and application when temperatures are above 15 degrees is recommended as optimal for rapid spore generation and spread.

At this time of the season, growers can apply BOTRY-Zen post-harvest and then again after pruning. The product can be tank mixed with one other compatible product such as copper or Actigard and may be applied to mature vines, development blocks and nursery plants.

BOTRY-Zen is available through major retailers.

Spray information on the KVH website has been updated to reflect BOTRY-Zen’s full label claim.
