Correct spray protection over spring
5 October 2017

Wet spring conditions are ideal for Psa build up and infection of young tender growth. Growers must maintain full spray cover over the season, particularly prior to, or directly after high-risk weather, on all varieties.

The online KVH Psa Risk Model can help with this and should be used to plan spray timings. The model is a weather-based tool that uses actual weather station data and weather forecast information to provide customised access to weather and disease interpretations.

There are several spray product options available – be sure to meet all user guide requirements. If applying bactericides ensure there are no flowers present in the sward or on vines. KVH has produced a fact sheet covering spray products and recommended timings, key points on pollination and preflower girdles. Copies are available here and at upcoming Zespri spring field day events.

Actinidia Import Health Standard
5 October 2017

Following a recent request by the Italian National Plant Protection Organisation and a New Zealand importer, the Ministry for Primary Industries (MPI) is working on an Import Health Standard for Actinidia nursery stock, specifically for plants in vitro (tissue culture). This pathway has not been active since 2013 as a result of the Psa incursion.

The importation of new kiwifruit material is recognised as an important component in maintaining the competitive advantage of our industry, however the risk of introducing new biosecurity threats must be carefully managed. 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.

At this point MPI are engaging with stakeholders to identify where further information could be provided to inform risk management decisions. KVH has been asked by MPI to participate in the process and will be fully engaged to ensure the associated biosecurity risks are fully addressed. More detailed consultation will occur with industry in 2018 but KVH will keep growers fully informed before any decisions are made on the outcome of this pathway.

Last month KVH and Zespri hosted international Brown Marmorated Stink Bug (BMSB) expert, Dr Tracey Leskey, to refine our approach for managing the pest should it manage to establish in New Zealand.

During her visit, Dr Leskey presented to kiwifruit growers at The Orchard Church in Te Puke and a new video of her presentation can be viewed
here.

The entomologist and researcher for the United States Department of Agriculture (USDA) discussed BMSB with around 100 people who attended the meeting to learn more about the unwanted pests impacts on horticulture, post-harvest facilities, and residential areas in the USA.

BMSB contributes to more than 30% fruit loss on Italian orchards
5 October 2017

Brown Marmorated Stink Bug (BMSB), along with spring frosts and vine diseases, are expected to have a considerable impact on the kiwifruit harvest in Verona and Veneto this season.

As noted at a late September convention of the Verona Chamber of Commerce, the regional production estimated for 2017 for Veneto is 35,761 tonnes, 33% less than 2016, while in Verona it will be 26,155 tonnes, 36% less than 2016.


Representatives at the convention from a Verona consortium for the protection of kiwifruit, said although the province must deal with root asphyxia kiwifruit is still very important to the region. KVH and Zespri have contributed funding to research to determine if pathogens are contributing to root asphyxia in Verona and therefore understand if this presents a biosecurity threat to New Zealand.

While the Italian figures are only estimates, they align with current KVH knowledge suggesting that should BMSB establish in New Zealand, impacts could include up to 30% fruit loss from fruit drop and storage rot.

KVH is in regular contact with Italian growers, alongside Zespri colleagues, and we closely follow trends that may also become apparent on orchards here. We noted in an April
Bulletin that bad weather in Italy had led to spring Psa infection higher than previous years, and we recently published a video on our YouTube channel showing the effects of BMSB on Italian orchards.

Orchard signage: keep it current
5 October 2017

Good biosecurity practice includes managing risk by restricting access to orchards. As part of this you should check contact details on your orchard gate signs are up-to-date.

Orchard visitors, harvest staff, and contractors need to know and follow your hygiene requirements.

KVH has produced new signage highlighting the need for visitors to make contact before entering and the biosecurity risk posed by plant, vehicle and people movements. If you would like new signs, they are available free of charge from your local packhouse and from KVH staff at Zespri OPC spring field days.

You are also welcome to pop into the KVH office in Mount Maunganui to collect a sign.

Committed to biosecurity and ready to act
21 September 2017

KVH’s strategy through to 2020 ensures we continue to be an effective and focused industry body.

The strategy reflects the significant change KVH has been through since our inception in 2011 when activities focused on Psa, to an organisation that now leads biosecurity protection on behalf of kiwifruit growers and industry. It’s based on a three-pronged defence – protection, readiness and response, and management.  

What does this mean in practical terms?

When we talk about protection, we’re talking about the work KVH does to help stop any biosecurity risk before it reaches our border (through global scanning to identify new risks and influencing government and industry) and ensuring nothing arrives here that we didn’t already know about.

This includes influencing policy setting and working with regulators to develop legislation that affects the industry. We’re a key Government Industry Agreement (GIA) partner, achieving maximum value in the delivery of cost-effective biosecurity operations. Read more here.

We focus on readiness and response activities so the industry is prepared and ready to respond quickly to any incursion. This involves having robust plans that are explicit about the roles and responsibilities all parties have, testing the plans (through simulations and workshops), and making sure everyone involved has the tools, systems and resources they need. Read more about our most recent incursion exercise here.

In the event of an incursion, KVH will lead ongoing management including on-orchard management strategies, making sure the industry is well coordinated, and assuring alignment with any Ministry for Primary Industries (MPI) activities. A big part of this work is promoting ‘best practice’ to reduce biosecurity risk to growers.

Underpinning the strategy is a comprehensive communications awareness campaign and a KVH/Zespri funded Research and Development programme that is providing pragmatic solutions to some of our biggest biosecurity issues.

The KVH Strategy 2017-2020 has been designed as a short, easy-to-read leaflet available online (growers will also have received a printed copy recently in their AGM packs) and includes a plan for how we'll operate to achieve results. 

Actigard™ is an important product for Psa management and should be incorporated into spring spray programmes alongside copper, to help protect new growth which is highly susceptible to Psa infection.

Actigard™ has systemic activity, and activates the plants natural defence systems within four to seven days of application. The active ingredient acidbenzolar-S-methyl is taken up rapidly, making the product effectively “rain proof” one hour after spraying. It moves both upwards and outwards into new growth and downwards to lower leaves and roots.

Trials have shown Actigard™ reduces leaf spot and flower bud infection and should be considered, particularly in areas where early signs of Psa infection have been found.

For mature vines, time first applications after leaves have reached 25mm in diameter, and for newly grafted vines (Gold3) begin applying Actigard™ once grafts are around 25cm long. Delay application if vines are under stress and ensure full label rates (20g/100L) are used. Repeat applications can be made 21 days later.  A second key application timing for Actigard™ is one to seven days prior to flowering, when other options for Psa control are limited and infection risk remains high. A maximum of four applications per season applies.

Refer to the Kiwifruit Technote Spring 2017.

Spring Psa spray programme
21 September 2017

As bud break in Gold3 is advanced in many regions, and Hayward bud break is upon us, growers are looking to protect new growth from Psa.

It is important growers develop and implement protective spray programmes that follow recommended best practice, including using recommended label rates and following product use conditions.

All growers looking to use bactericides should ensure they comply with the additional requirements associated with these products, including the completion of an Orchard Psa IPM Strategy (OPIS) "intent to spray" form and site inspection forms.

Further spray information details are also available on the KVH website.

Reminder of pruning and tying down timeline
21 September 2017

Growers are reminded that one of the requirements within the National Psa-V Pest Management Plan is that orchards are pruned and tied down by 1 October yearly.  KVH is aware that this winter has been very challenging with more wet weather than usual and that pruning and tying down is still being completed on some orchards. 

If an orchardist or orchard manager thinks they are unlikely to meet the 1 October timeframe, contact KVH so that we are aware of your situation and can discuss and agree a way forward.
