Zoning in on Psa risk and winter chill
13 June 2019

The Psa Risk Model shows current and forecast daily assessments of Psa infection risk based on weather. This gives growers a heads up of upcoming high-risk periods to assist planning of pruning and spray rounds.

Through the leaf-fall period, application of winter rate copper to protect new leaf scars is recommended, and after pruning rounds copper should be applied to protect pruning wounds.

Weather forecasts are also available via the model, as are chill unit calculators showing seasonal and historical chill unit data. Chill unit comparisons are available across years and between locations.

A reminder that when logged in you can also click the ‘Station Locations’ link to the right of the options box to see exactly where the weather stations are in your area.

Unusual symptoms reported
13 June 2019

When information about unusual symptoms is reported to KVH (by growers, contractors, packhouse staff and others visiting orchards) it is then looked into to be sure that any biosecurity risk is identified, managed and the growers involved are well supported if any further action needs to be taken.

KVH prepares full reports on every investigation which you can read online.

Last week the following report was added:

·         Armillaria mushrooms on rootstock: a cluster of mushrooms were found on a Bruno stump within a mature Hayward block 

This information is provided to help identify similar symptoms others may be seeing on their own properties and to increase general awareness of the importance of reporting unusual symptoms.

Stay vigilant, be on the lookout, and report any unusual disease symptoms to KVH on 0800 665 825 or email info@kvh.org.nz

Have you completed your orchard's biosecurity plan?
13 June 2019

Kiwifruit growers are encouraged to strengthen biosecurity plans through a new guide from KVH.

Implementing on-orchard biosecurity is the responsibility of every person working on or visiting an orchard. With several high-profile pest and disease introductions into New Zealand over the last decade, including Psa, kiwifruit growers and orchard workers need to be biosecurity aware to protect themselves and surrounding businesses.

The new 5 step on-orchard biosecurity guidelines are a set of measures designed to protect a property from the entry and spread of pests and diseases and have been developed to provide guidance, help identify risks, and how to address them.

By using the guidelines to develop a biosecurity plan, you will be able to identify and prioritise biosecurity practices that are relevant to your orchard and property and be able to treat biosecurity planning in a similar manner to quality assurance or risk planning such as Health & Safety or emergency preparedness.

What is a biosecurity plan?
It's a document that outlines how you manage your orchard and how you will respond to a pest or disease outbreak. It describes your processes on-orchard and how you are addressing biosecurity risks.


It can be as short, or long, as you need - the new 5 step on-orchard biosecurity booklet is designed to be used as a template, with tips and suggestions for customising a biosecurity plan that works for your operation and that can be built on over time.

Make sure that as you personalise your own plan, you involve all orchard staff and contractors so that everyone becomes engaged with the common goal of keeping your orchard and fruit safe.

Having a biosecurity plan in a biosecurity response or an emergency is critical. Early detection and reporting give us the opportunity to supress any kind of serious disease.

Why have a biosecurity plan?
As a grower or person in charge of an orchard, you need to have a plan that covers the steps you take when moving machinery, tools and plant material on and off your property, how you trace and record all these things, how you manage the risks that might already be present, and the steps you should take if you see anything unusual. 

By having a plan written down you can get everybody who's involved in your business on the same page.

Investing a little time in establishing good biosecurity practices on your orchard promises a hundredfold reward, not only through the smooth operation of day-to-day business but the avoidance of financial problems. movement restrictions, and possible market access issues in the future from unchecked disease or pest populations.

The new 5 step on-orchard biosecurity guidelines booklet is available from KVH by phoning 0800 665 825 or emailing info@kvh.org.nz. Copies will be distributed in the GAP grower manual update packs distributed by Zespri. You can also view and download a copy here.

Be on the lookout for BMSB over winter
13 June 2019



As mentioned in the last Bulletin, KVH and other horticultural groups are working together again this year on keeping the BMSB profile up over the winter months. The above video, featuring new close up footage of the BMSB, will be used on social media and other online advertising over the coming 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. Successful advertising from last year through the MetSerive app and shopping mall displays/TV screens will be repeated again.

Tauranga Moana response prearedness
13 June 2019

In light of the current fruit fly response, KVH was part of a Tauranga Moana Biosecurity Capital (TMBC) workshop last week that looked at how prepared we are in Tauranga for a biosecurity incursion.

Around 40 people from a wide range of industry, community, biosecurity and education groups attended as well as central and local government, and iwi partners.

The workshop focused on how the Ministry for Primary Industries (MPI) responds to biosecurity incursions, the roles and responsibilities as set out in the incident mangement framework they use, presentations on the reality and practicalities of a biosecurity response (the fruit fly and Rena responses were used as examples), and the role of TMBC in supporting a response.

Whilst TMBC is not a response entity, the network was created a year ago to ensure plans and relationships are developed and prepared so that should a major incursion occur in the region, resources can be immediately activated to support response activities and help get information out.

From here, TMBC will be looking at further opportunities for response training so that the regions large pool of expertise can be used if called upon.

Auckland fruit fly detections
13 June 2019

On the ground efforts to manage the recent fruit fly detections in Northcote, Auckland, continue with the possibility of some controls remaining in place throughout winter.

Over the past month, operational activity has stepped up to include placing bait on fruit trees to attract and kill adult flies, in particular females, and the continuation of intensive trapping. The risk of finding further fruit flies is still a concern, and the focus on maintaining controls and continuing with baiting and trapping remains a priority.

Despite the large on the ground efforts, another male fruit fly was found at the end of May in one of the network of fruit fly traps. The single male fruit fly was found just 80 metres from the last detection on 10 May. There still has been no larvae, pupae or female flies found to date.

Spreading the biosecurity word at Fieldays
13 June 2019

KVH has enjoyed a busy start to the annual Mystery Creek Fieldays.

Growers visiting our stall within the Zespri hub have shown a strong interest in biosecurity issues and the lunchtime sessions with presentations from Zespri, KVH and NZKGI have been well-attended.

Fieldays has given us the perfect opportunity to launch our new biosecurity booklet for growers, which has been very successful.
The 5 step on-orchard biosecurity guidelines are a set of measures designed to protect a property from the entry and spread of pests and diseases and have been developed to provide guidance, help identify risks for the orchard and how to address them. Growers should use the guidelines to develop a biosecurity plan that works for their orchard/property. Read more about the guidelines here.

KVH is also taking the opportunity to catch up with importers of tractors and other machinery, to ensure they are aware of the risk of pest threats like the Brown Marmorated Stink Bug (BMSB) and the protocol to follow if they find anything unusual on any of their shipments.

Chief Executive Stu Hutchings and KVH staff will be based in the Zespri hub at Mystery Creek again tomorrow – please drop in and say hello.

Help lookout for wild kiwifruit vines
30 May 2019

As we head into winter, growers are asked to look out for wild kiwifruit vines in any areas of bush, scrub or forestry near kiwifruit orchards. 

Wild vines can harbour pest organisms, degrade the biodiversity value of bush and productive value of forestry. They are at their most visible in early winter when leaves turn from green to yellow.  

Growers can report wild kiwifruit locations to their local regional council or KVH by emailing info@kvh.org.nz.

A reminder as published in the last Bulletin, that unpicked kiwifruit must be removed from vines by 1 July. Read more here.

Beetle to control the weed moth plant
30 May 2019

The moth plant beetle, an organism new to New Zealand, can now be used in the fight to control moth plant.

In mid-May the Environmental Protection Authority (EPA) approved an application by Waikato Regional Council to import the beetle. Read more about the EPA decision and process here.

Moth plant is a problem weed on many kiwifruit orchards, especially from the Bay of Plenty north. It infests shelter belts, slows down hedge trimmers and is a major host of Passionvine hopper. 

The moth plant beetle feeds on moth plant foliage but this damage is not usually significant.  Eggs are laid on or in the ground around the base of the stem and hatching larvae burrow down to feed on moth plant roots.  The beetle is specific to moth plant and will not attack kiwifruit or any other orchard plants.  

This approved biocontrol agent will hopefully assist in the long-term control of moth plant – in the meantime orchardists should maintain removal programmes, especially as it is a weed often smothered with Passionvine hopper.  It is a poisonous plant, the sap may cause severe dermatitis through any skin contact, so PPE must be worn when removing this plant. 

The most effective control method is to dig plants out of the shelter belt, being careful to remove all of the roots.  Alternatively, the plant can be killed with herbicide: cut the vine to within 20cm of ground level and carefully apply one-part glyphosate to five parts water, plus a sticker such as Pulse, to the vine base.

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.
