Farewell from Stu
1 April 2021

After three years at KVH, next week is my final week and this is my last Bulletin, as I leave the industry to take up an exciting new role as New Zealand’s Chief Biosecurity Officer at the Ministry for Primary Industries (MPI).

It’s difficult to reflect on my time at KVH in a few sentences but I want to acknowledge and thank you all for the support of myself and the team.

I’ve been particularly impressed with the leadership demonstrated across the industry. Everyone is willing to tackle the big challenges and issues, while remaining focused on what is best on-orchard, for growers. Late last year we acknowledged the 10-year anniversary of Psa arriving in New Zealand and it was a real reminder that the united front and proactive biosecurity thinking shown in more recent years – with the development of the proposed Pathway Plan; Auckland fruit fly response; and Mount Maunganui stink bug find - have come about because of where the industry has been in the past and what growers have been through.

Many thanks to past and present members of the KVH team and Board too. Bulletin readers will know them well and see them often – they’re a committed group of people who I have no doubt will continue to raise the bar for biosecurity practice and preparedness into the future.

I’m not going far (physically or job wise) so please do say hello if you see me around. I’ll continue to be based in the Mount and with my MPI hat on I’ll be keenly keeping up with the continuing proactive activities of KVH and the kiwifruit industry.

KPCS nurseries come together
1 April 2021

Twenty nurseries and other associated parties were represented last week at a KVH forum to strengthen communication and partnership with plant producer members of the Kiwifruit Plant Certification Scheme (KPCS).

There were several informative presentations during the event, as well as discussions and feedback opportunities, particularly related to planned enhancements of the KPCS so that it aligns well with the proposed new Pathway Management Plan and Plant Production Biosecurity Scheme. The forum also discussed recent unusual symptom reports and the importance of contacting KVH as soon as unusual disease symptoms, or pests, are noticed.

A copy of the presentations from the day is available here.

Growers should have confidence that kiwifruit nurseries are managing biosecurity risks associated with kiwifruit rootstock movement through their compliance with the KPCS. Other industries also have similar schemes in place, with their growers recognising the value of certified plants.

One of the most important aspects of the KPCS, and a cornerstone of biosecurity across the entire kiwifruit industry, is sourcing and tracking clean plant material - one of the five key steps within the Kiwifruit Growers Biosecurity Guidelines.  

Growers can reduce risk associated with plant material by following movement controls, inspecting all material when it arrives on the orchard, and keeping up to date records that maintain traceability – i.e. where plants (and budwood) have come from and where they went to on the orchard. A template and check sheet for this are included within the guidelines (Step 3).

Reminder to order nursery plants in advance
1 April 2021

When we visit nurseries as part of the Kiwifruit Plant Certification Scheme (KPCS), we’re reminded of how important it is to those businesses that growers order their plants well in advance.

Without a reliable estimate of anticipated demand for the next season nurseries take a conservative approach to avoid getting left with unsold stock. Growers should order plants as far in advance as possible – preferably a year – to avoid any shortage in supply.

Growers must only purchase plants that are KPCS certified and KVH movement controls must be observed. With the 2021 Zespri Licence Release this is a timely reminder that there are still Exclusion areas in the Far North and South Island.
As the red budwood currently being supplied by Zespri is all from Psa positive orchards, these orchards and any orchard in any region which is Not Detected cannot currently obtain Red19 budwood.

Greenfields developments are considered Psa Not Detected so should be sourcing Full Certification plants. If you have a new development that does not currently have a Zespri KPIN, and you are wanting to source plants from a kiwifruit nursery you will need to contact KVH to be issued with a Greenfields number (until you have a KPIN) so the nursery can supply you with plants.

A list of nurseries and their KPCS status is available on the KVH website.

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

Autumn Psa strategies important
1 April 2021

Growers are reminded of the value of monitoring their orchards for evidence of Psa through autumn. Psa inoculum can be mobile within orchards regardless of the time of year but risk always increases as temperatures drop and periods of rain increase.

This image taken last week clearly signals exudate production is being triggered by our current weather patterns, and the recommendation is removal (and effective disposal) of the Psa infected material to help reduce this reservoir of Psa inoculum.

Other tell-tale signs of inoculum build-up include new spotting on Bruno suckers or new growth, especially in new development blocks which are more vulnerable to infection.

It can be more difficult to identify new infections in Gold3 blocks as leaf spotting is less prevalent, but the trap plant data from the recently completed Gold Futures research project clearly demonstrated inoculum presence in autumn for most sites.

A strong copper programme is recommended to protect new development blocks and also harvested blocks, as well as Actigard for blocks where there is no risk of residue to unharvested fruit. Research has shown defence genes in mature Hayward leaves are upregulated following post-harvest applications of Actigard and work is in progress to confirm effects on Gold3. Read the latest Actigard post-harvest technote here.

Kiwifruit Phytophthora survey
1 April 2021

As mentioned in the last Bulletin, KVH, Zespri and Plant & Food Research are currently working together on a survey of Phytophthora pathogens in kiwifruit orchards throughout New Zealand.

The autumn sampling round is in full swing but there is still opportunity for growers in the Bay of Plenty and Waikato areas to be included. We are particularly keen to include any sites in the Whakatane and Opotiki areas with suspected Phytophthora symptoms to ensure we get a good spread of sample sites.

Growers who have vines with known or suspected Phytophthora symptoms and who would like to be involved in this survey can read more about the project here.

The impact of Psa seared into the mind
1 April 2021

It arrived like a whisper but fast turned into a scream. Psa was first identified in New Zealand just over 10 years ago and what followed was one of the most tumultuous times in the history of the New Zealand kiwifruit industry. Now KVH has commissioned a project which follows some of the main players from those early days of Psa and tells their stories.

Click here to read some spine-tingling excerpts from two such tales, which will be included in the upcoming special book release of reflections from the kiwifruit industry’s biggest biosecurity response and recovery.

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

The good news is that new data from Biosecurity New Zealand shows there were no detections of exotic fruit flies for the latest reporting period (February). Read more in the latest of the monthly KVH risk updates here.

KVH has also developed a helpful guide for growers detailing the likely sequence of events if a fruit fly response were to occur in a kiwifruit growing region. You can download the guide here or contact us if you would like a copy printed and sent to you.

Biggest offshore threats monitored
1 April 2021

KVH maintains a register of potential biosecurity threats (pests and pathogens) to the kiwifruit industry, increasing our awareness of offshore risks and supporting our readiness work so that we are ready for the next possible biosecurity event.

As well as scanning English literature, KVH and Zespri have undertaken several projects to access kiwifruit information in Chinese language literature. Previous translation work has focussed on pests, namely the Brown Marmorated Stink Bug (BMSB) and Spotted Lanternfly, but we are now also looking at what potential kiwifruit diseases and pathogens are talked about in wider Chinese literature.

Preliminary work has been completed and our offshore risk register has been updated to include several new organisms. There are now over 80 pests and pathogens, with varying degrees of risk, on the register available here.

The great Tauranga Moana biosecurity hunt: calling all adventurers
1 April 2021

Have you got what it takes to hunt down the 18 ‘Most Wanted’ invasive insects, animals, weeds, and diseases and protect the Bay of Plenty?

From tomorrow (Friday), the great biosecurity hunt will go live – a simple interactive virtual hunt aimed at raising awareness and entertaining kids over the Easter and school holidays.

There are hunts in Mount Maunganui, Tauranga, and Papamoa. Complete the hunt closest to where you live or do all three. There are six invasive insects, animals, weeds, and diseases ‘hiding’ throughout each location that you catch using any smartphone and the free Actionbound geocaching app.

Each hunt is between 3.5-4km’s and you can do them on a bike, scooter, skateboard or on your feet anytime between 2 April and 3 May.  

Each completed hunt goes into the draw to win from a $2500 prize pool supporting our local tourism and hospitality businesses. These will be drawn at the end of every week and range from paddle boarding to fine dining, to virtual reality and much, much more. 

Details and step-by-step guides for playing are available at www.greathunt.co.nz. Good luck!

The hunt has been put together by the Tauranga Moana Biosecurity Capital (TMBC) initiative, of which KVH is an active member, raising biosecurity awareness throughout the community and local schools as an extra layer of protection for our industry and orchards. If you’re in Mount Maunganui look out for our giant banner about the hunt on the grain solo at the corner of Totara St and Hewletts Road too.

Man fined for biosecurity breaches: An Auckland businessman has been convicted and fined $30,000 for breaking rules intended to keep New Zealand safe from pests and diseases and trying to cover it up.

Sea containers imported into New Zealand must be sent to registered sites and opened at approved transitional facilities to ensure any biosecurity risk is addressed. The manager and owner of Divine Logistics Limited was sentenced for breaking both requirements and providing investigators with falsified documents.

Check out that camouflage! There are two Spotted Lanternfly egg masses on this tree – can you spot them?

It isn’t easy and goes to show how important it is to be on the lookout for this pest and its eggs because the sooner we find out about its possible presence, the more we can do to stop it establishing and spreading far and wide.

Easier than ever to forecast disease risk
1 April 2021

With the launch of a new version of the KVH Weather & Disease Portal it’s now easier for growers to see and assess weather patterns for their orchards. The portal is an important and useful tool that is used daily across the kiwifruit industry.

The current portal remains available, but growers can opt-in to try out the new version. This is a big step forward in working towards allowing growers to privately connect their own weather stations, enabling orchard specific weather and forecasts, localising the output of the tools like the Psa risk model.

Everything from the current portal is available within the new version along with some initial improvements: 

  • New extended 15-day forecasts for every weather station location.
  • Updated dashboard featuring current conditions and evapotranspiration (ET).
  • Ongoing mobile-friendly design improvements so it's easier to get the information you need on any type of device.
  • Faster and more responsive platform enhancing overall usability.

You need to log-in to access the portal which you can do here. If you don’t have a log-in, register for access here or contact KVH at info@kvh.org.nz.

Once in the portal you will see a banner on the top, click on this to try the new version and let us know what you think. If you have any questions or comments please feel free contact us at info@kvh.org.nz

Are you interested in privately connecting your weather station to the portal? Register your interest with KVH at info@kvh.org.nz.
