Heightened awareness for hitchhikers
30 April 2020

Since the start of the high-risk season in September 2019 there have been 57 Brown Marmorated Stink Bugs (BMSB) found, about a quarter of what was found at this time last season, indicating management processes – especially those undertaken offshore – are working.

We are nearing the end of the high-risk season for BMSB with none of the bugs found in New Zealand for several weeks now.

However, as we move in to COVID-19 Alert Level 3 and many more goods are moving again (including out of containers and transitional facilities where they may have been in storage for weeks) growers and the public are reminded to keep an eye out for stink bugs and other potentially hitchhiking pests (dead or alive) that could have been hiding out in stationary cargo during the lockdown.

KVH put out a press release on Tuesday reminding people of the importance of being extra vigilant when opening either new to New Zealand parcels or non-essential items that have been in storage while we were at Alert Level 4. You can read the release here.

More detail about this year’s high-risk season can be read in the latest monthly KVH BMSB risk update, which includes data reported by Biosecurity New Zealand.

Autumn Psa reminder
30 April 2020

This week a Gisborne grower forwarded this image of a young Gold3 trunk showing recent Psa exudate. It provides an important reminder that despite a long dry summer, Psa never really goes away and can quickly reactivate as temperatures cool and rain periods become more prevalent.

A number of plants in the same block had internal staining in some pruned canes with this also indicating a level of Psa infection within the block. Care was taken to cut back beyond the infected tissue and good tool hygiene was maintained to avoid disease transfer.

Copper at winter rates was applied to the pruned canopy and as there was still a good level of green leaf available, Actigard was also included to provide added protection against further autumn and winter infection.

A reminder good autumn Psa protection is also important for mature fruiting blocks. Copper should be applied as soon as possible after fruit harvest and if the canopy condition allows and there is no risk of drift to unharvested fruit. Actigard should also be applied. As a rule of thumb ensure at least 50% of canopy leaves are still green if using this plant defence elicitor. More details on the use of Actigard can be found here

Moving budwood
29 April 2020

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 any Zespri licensed varieties 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.

·        Budwood collection areas must also be monitored. Any unhealthy vines, or vines showing any symptoms, are to be tagged and not used for budwood supply.

·        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.

Preparing to fight Phytophthora
29 April 2020

We’ve added another new page to the Kiwifruit’s Most Unwanted section of our website, this one all about Phytophthora.

Phytophthora is present around the world, including New Zealand, in a wide range of hosts. There are over 100 known species, with thoughts there could be up to 500 more yet to be identified.

It’s thought highly likely that under certain conditions (i.e. wet soils) kiwifruit would be susceptible to several Phytophthora species. Predicting which species will impact which cultivars, and under what conditions, is difficult if not impossible to achieve. Because of this, KVH is undertaking readiness planning and research for invasive Phytophthora species as a whole, as opposed to focusing on one specific species.

The new web page includes information about this work, images, fact sheets and other Phytophthora reference material to help growers understand the risk posed by this threat and how to identify symptoms.

One of the research projects detailed on the page is a survey of orchards throughout New Zealand being undertaken by KVH, Zespri and Plant & Food Research. Sampling of orchards was set to kick off in autumn (May), but while we all continue to support COVID-19 efforts, it has been decided to delay to the first round of sampling until spring (September) and under the appropriate alert level.

Heightened awareness for hitchhiking pests
28 April 2020

People are being encouraged to keep an eye out for hitchhiking exotic pests now that the country heads into a new alert level and many more goods are moving again.

“We’re asking everyone to look out for anything unusual they might notice in parcels and packages so that we find unwanted pests early” says Kiwifruit Vine Health Chief Executive, Stu Hutchings.

“The Brown Marmorated Stink Bug (BMSB) in particular is a big biosecurity threat and even though we’re nearing the end of the most risky time of year for these bugs, they could still be hiding out in new-to-New Zealand parcels or non-essential items that have been in containers or storage while we were at Alert Level 4.”

The BMSB is a major concern to the kiwifruit industry and other primary industry groups because it can destroy fruit and vegetable crops and is also a significant public nuisance that will readily invade and infest people’s homes and outdoor spaces in large numbers, making it one of the top most unwanted pests that every New Zealander will want to keep out of our country.  

“The impact from these bugs could be huge for the kiwifruit industry and the Bay of Plenty. In Italy, the bugs have been found to cause up to 40% drop in kiwifruit prior to harvest. This could wipe income of growers and across the horticultural sector the impact on GDP could be in the billions.”

Stu adds that the kiwifruit industry is pleased the local Biosecurity New Zealand team have continued to work with Transitional Facilities in the area (where biosecurity goods are held and inspected before being cleared) during the lockdown period.

“There are facilities that have remained open to manage the throughput of cargo and we know Biosecurity New Zealand have been busy interacting with them about biosecurity risk and the necessity to maintain high standards. There will be an increase in risk goods being discharged or unloaded as we shift levels, all of which will continue to be inspected.”

“There is never zero risk however, which is why we also need the public’s eyes and ears at the delivery end of the chain – they’re key to finding unwelcome hitchhikers quickly enough to be able to do something about them and make sure they don’t then spread throughout the community and onto orchards.”

“If you’ve seen any kind of pest or bug that you don’t recognise and think looks unusual, catch it, snap it and report it by calling the Biosecurity New Zealand hotline on 0800 80 99 66.”

The borders are closed but has our biosecurity risk gone away?
16 April 2020

KVH is calling upon growers to ensure that on-orchard biosecurity for kiwifruit pests and pathogens is not forgotten and most importantly to keep an eye out for any unusual vine symptoms during harvest and report these to KVH for follow up. If an incursion were to occur now - while the country is facing an unprecedented human health and economic challenge - the impact could be severe.

While borders are closed, cruise ships berthed, and incoming trade a trickle of its usual volume, biosecurity risk still exists, especially from the spread of kiwifruit pathogens that may already be here in their latent (not showing symptoms) form. Coronavirus has clearly illustrated the challenge of managing pathogens during the latency period, where they can spread silently between asymptomatic hosts. The same logic applies to plant pathogens except the latent phase can be much longer than 14 days and extend out to months or even years.

For some of our most significant threats like Ceratocystis fimbriata, the pathogen impacting kiwifruit in Brazil, we don’t even know how long the latency period in kiwifruit is but we look to other hosts like Eucalypts where it is thought to be about seven months for new plantings. Our challenge is to apply biosecurity practices all the time so that if this or any other pathogen were to arrive, we wouldn’t be spreading it around unknowingly.

We can’t afford to lock down plant material movements, these underpin the growth of our industry. But, by applying certification standards and embedding biosecurity practices across the plant production chain we can increase our confidence that these movements are safe. Should failures occur, we need robust traceability systems to know where infected material may have gone and where it came from originally. These are some of the key principles behind the proposed pathway plan (click here to read the latest Bulletin article about this) to ensure safe movements of risk goods across our internal industry pathways.

Underpinning all these principles is the need for growers to report any unusual vine symptoms so that KVH and the Ministry for Primary Industries (MPI) can follow up and undertake diagnostic testing. Growers should take reassurance that in almost all such cases there is no cost to the grower and no resulting restrictions that impact their operation. Even if a response was to be launched the grower would likely be eligible for any losses under the Biosecurity Act.

The earlier we detect the presence of a new biosecurity threat the earlier we can act to contain it, which gives us the very best shot at eradication.

To report anything unusual call KVH on 0800 665 825 or email info@kvh.org.nz.

We’re still in the high-risk season for fruit flies, with close monitoring and site trapping continuing.

Latest data from Biosecurity New Zealand includes great news – there were no fruit fly detections in New Zealand in March. Our closest neighbours, Australia, do have a couple of new responses underway however which proves the risk of flies/larvae getting here is never too far away. You can read more in the April KVH risk update here.

Remember to be vigilant, keep watch, and report anything unusual to either KVH on 0800 665 825 or Biosecurity New Zealand on 0800 80 99 66.

Progression of new Pathway Management Plan
16 April 2020

Late last year, KVH announced to growers that we were starting to look at a new regulation framework to better manage biosecurity risk to the kiwifruit industry, and asked for feedback on our early, high-level thoughts about specific activities the Plan will help manage, and how it will be put into action. A key driver was to ensure that we have measures in place to prevent the spread of a broad range of biosecurity threats, rather than our current regulation, which is specific to a single organism, Psa.

The feedback we have had so far has been supportive, with growers and industry considering the concept of the Plan a logical and sensible way to manage biosecurity risk going forward, especially if this can be achieved without an increase in cost to growers.

Development of the Plan is advancing well. A detailed draft has been prepared and we continue to work with the Ministry for Primary Industries (MPI) to ensure it aligns with over-arching biosecurity legislation and regulations. We expect that a full plan and implementation schedule will be shared mid-year for your input before it is finalised.   

A one-page summary about the proposed new framework can be found here and feedback about the proposed Plan can be provided to KVH by email at info@kvh.org.nz or by phone at 0800 665 825.

More information, including a detailed consultation paper and submission form are also available on the KVH website here.

Since the last Bulletin a lot has changed for us all - as growers, teams, businesses, and a nation. The Covid-19 situation is unprecedented and evolving by the day. We’re sure that each of you have been focused on making the best possible decisions for your families, staff and businesses that ensure you all stay safe and align with our nationwide goal of slowing the spread.

As a food producer, the kiwifruit industry is considered an essential service under alert level 4 - as is biosecurity. This means that all parts of the industry, including KVH, continue to operate, albeit under enhanced conditions that include strict registration and hygiene protocols.

KVH staff are all working remotely and are available to provide assistance and advice – everyone’s contact details can be found here on our website (easily accessible from the home page anytime). 

You can also be assured that as it is classed as an essential service, biosecurity activity continues at the border and post-border. This means things like ongoing surveillance programmes, testing and trapping activities continue (with appropriate measures in place to protect people) as do our regular conversations with Biosecurity New Zealand. 

The team are in close contact with Government, Zespri and NZKGI ensuring we do all we can to ensure our people and industry are well supported.

Sanitisers and orchard hygiene
2 April 2020

Growers are reminded that by following Psa best practice orchard hygiene during harvest they may well be protecting themselves and workers against Covid-19.

For example, plain Janola (unscented) at 1% if used on picking bags to kill Psa has also been shown to inactivate coronaviruses within a minute (read the science article here). Not all sanitisers have been proven to be effective against coronavirus but Janola is a simple and easily available product which can also be used to disinfect tractor steering wheels and gear levers if these are being used by multiple people. Nuron Biosafe, being a sodium hypochlorite product, is also effective against coronavirus and suited to organic and conventional orchards alike. Refer to the KVH website for more information on harvest hygiene and sanitiser effectiveness.

The NZKGI website has information on industry protocols specifically for Covid-19.
