Managing the risk from imported plant material
26 July 2018

On 13 July 2018, the Ministry for Primary Industries (MPI) issued an Import Health Standard (IHS) for Actinidia plants for planting. This means that kiwifruit plant material can be imported into New Zealand to be used for planting purposes, including but not limited to, use in breeding programmes if it meets the requirements of the IHS.

The IHS sets out the import requirements for Actinidia nursery stock, specifically for plants in vitro (tissue culture), imported into New Zealand for further propagation. This pathway has not been active since 2013 because of the Psa incursion.

KVH recognises importing new kiwifruit material is an important part of maintaining the competitive advantage of our industry. However, KVH has been actively engaged in the consultation process to ensure that the risk of introducing new biosecurity threats on this pathway is carefully managed and has therefore sought independent reviews from New Zealand and international experts to ensure measures are robust.

Importation is restricted to tissue culture material which is less likely to introduce threats than other forms of plant material. MPI has taken a precautionary approach to developing this Standard. Where uncertainty exists on the ability of a measure to manage risk, more than one measure is required. These include a combination of offshore measures; two years post-entry quarantine in conditions conducive to symptoms expression and regular inspection; and diagnostic testing.

Farmlands onboard with biosecurity
26 July 2018

Farmlands Horticulture hosted their annual Subtropical Crop Technical Update in Tauranga last week, this year broadening the scope of the three-day conference to also include a biosecurity presentation by KVH as well as an update on latest Psa research findings from the Zespri Innovations team.



Forming a key link with growers, the Farmlands team are looking to be proactive in understanding the biosecurity risks posed to their large horticultural client sector. Staff from Northland to Motueka attended and KVH presented their organisational role in the building of a resilient kiwifruit industry. Diseases of high risk to the kiwifruit industry and current border pressure from the most unwanted pests was highlighted. Of these, it was clear that incursions by pests such as the Brown Marmorated Stink Bug (BMSB) would undoubtedly have effects, spilling over to other horticultural and agricultural sectors. Farmlands recognises the importance of biosecurity and as a result are looking to roll out the discussion presented at the seminar via KVH to other Technical Reps involved in high value crops such as the pipfruit and viticulture industries as technical sessions take place.

Keeping a look out for unusual pests and symptoms and starting a conversation about biosecurity with growers both in-store and on-farm was considered a hugely valuable and proactive role all staff could be engaged in on a daily basis and a contribution towards building a biosecurity team of 4.7 million.

Putting the Samurai Wasp case forward at hearing
12 July 2018

KVH spoke on behalf of the kiwifruit industry at an Environmental Protection Authority (EPA) hearing yesterday, cementing support to release the Samurai Wasp in the event of a Brown Marmorated Stink Bug (BMSB) incursion.

The hearing is the final step in the application process to introduce the wasp as part of eradication or control efforts if an established population of BMSB is found here.

KVH Biosecurity Manager, Matt Dyck, presented with a focus on the importance of the kiwifruit industry to the local and national economy (now and into the future); the potentially devastating impact of BMSB; and the reasoning for why the wasp is viewed as the best overall control tool available. The EPA will be making all hearing presentations available to the public shortly. Please contact KVH if you would like to know more about what was discussed at the hearing. 

From here, the decision-making group will consider the application (not open to the public) and a decision is expected by mid-August. The EPA has previously released their staff assessment report, which recommends the decision-making group approve the application.

The application was made to the EPA by KVH, Horticulture NZ and other horticultural industry groups through the BMSB Council as part of the Government Industry Agreement (GIA).

Remove unpicked kiwifruit from vines
12 July 2018

Growers are reminded that there must now be no unpicked kiwifruit left on vines. Under the National Psa Pest Management Plan (NPMP) it is a requirement that all orchard vines must have picked fruit by 1 July each year.  KVH will follow-up reports of unpicked fruit with orchard owners and post-harvest companies.

Unpicked fruit can result in an increase of the amount of wild kiwifruit vines establishing in nearby areas of native bush or exotic forestry as fruit ripening over the winter months provides a food source for birds, which spread seed. Unmanaged vines, including those with unpicked fruit, may also be a potential host for plant disease organisms.

Biosecurity awareness needs work: The Minister of Agriculture and Biosecurity says more work needs to be done to help New Zealanders understand biosecurity threats. A recent survey has found more than 60 per cent of New Zealanders think biosecurity is important, but only 2 per cent think they would be personally affected by a breach.

Scientists sic Samurai Wasps on stink bugs: US researchers released the wasps as a biocontrol agent against the Brown Marmorated Stink Bug (BMSB) on 56 farms and agricultural sites and found ‘as a biocontrol agent, the wasp is not only very effective at reducing the population of BMSB, but the least environmentally damaging of all the options for controlling this pest in both the urban and agricultural system’.

Biosecurity nightmare halted at border: A traveller’s grisly gift for his family did not make it past Auckland airport biosecurity officers - arriving from Apia late June, the passenger declared a bat’s head to staff which was seized and destroyed. Bats have a terrible reputation as disease carriers and the item could have harboured hitchhiker pests.

KVH meets with Maori Grower Forum
12 July 2018

Just over a year on from the initial launch, KVH presented at the June meeting of the Maori Kiwifruit Grower Forum late last month.

The group advocates on behalf of growers and ensures they are well informed of key issues. Biosecurity is one such issue, and KVH Chief Executive Stu Hutchings discussed with the group the application before the Environmental Protection Authority (EPA) for approval to release the Samurai Wasp in the event of a Brown Marmorated Stink Bug (BMSB) incursion; potential changes to regional boundaries within Recovery regions; and the importance of improving traceability of all plant and plant material within the kiwifruit industry.

KVH also took the opportunity to thank the Forum for their ongoing commitment to biosecurity activities, particularly the groups submission to the EPA in support of the Samurai Wasp application.

Learning more about copper resistance and implications on-orchard
12 July 2018

KVH and Zespri, along with science partners, have been focussed on learning more about copper resistance over the years and we have made great progress in our understanding of this complex subject area. A science workshop was held early July to discuss latest research results and further requirements, with the aim of answering the question: “How does our knowledge from the laboratory translate to the field?”

Participants in the workshop came from Otago University, Massey University, Plant and Food Research, Hills Laboratories, and Verified Lab services as well as KVH and Zespri. 

Russel Poulter from Otago University presented DNA sequencing results from more than 100 Psa samples that were collected from across North Island growing regions. The main learnings from this work show that there are low level resistant Psa bacteria with some resistance to copper present in all North Island regions. The mechanisms leading to resistance are present in other bacteria and are transferring to Psa. To date, approximately eight different resistance mechanisms have been identified with the most common ones present in all regions. Some of the mechanisms are very efficient at transferring from other bacteria in the environment to Psa (leading to an increased presence of these strains) while other forms are less efficient and less prevalent.

Joel Vanneste from Plant and Food presented the results of an intensive study carried out on a Te Puke orchard where young kiwifruit plants were placed in 10 different locations in the canopy at different times throughout the year and Psa bacteria on each plant was analysed.  The learnings showed there is huge variability in forms of low level resistance present on-orchard and between locations, even within the same orchard. Both low-level resistant and non-resistant strains can be readily present at a location - even on the one leaf. Multiple resistance mechanisms can also be present at the one location.

Copper spraying at recommended rates is still effective at killing Psa strains with resistance mechanisms. Timing of spray application and weather conditions can have a big impact on the efficacy of copper use. Further analysis of the samples collected is planned to provide more information, which along with additional research will help us in reviewing our recommendations around copper spraying.

Advice for growers on how to reduce the potential for copper resistant bacteria to impact copper spray efficacy is:

·        ensure full label rates are used and good canopy coverage is obtained (the use of spreaders will assist improved coverage),

·        look to alternate copper use with other protectant sprays when timing permits,

-      extending the timing between copper sprays when risks of Psa are lower (hot, drier weather) may help reduce resistant populations as a percentage of total Psa populations.

Changes to regional boundaries effective next Monday
12 July 2018

Following consultation with growers and nurseries and consideration of submissions, KVH is revoking all regional boundaries within the Recovery regions in the North Island, creating one region with geographically separate locations. This change will be in place from Monday 16 July 2018 and updated documentation is available on the KVH website.

Thank you to the growers and nurseries who gave KVH their feedback during the consultation. Submissions were primarily in support of the proposal. Regional boundaries and classifications (based on the level of Psa infection) are important to protect areas with little or no Psa but did provide some inequities around plant material movements, especially between Recovery regions.

Following this change, there will also be an amendment in the description of nurseries under the Kiwifruit Plant Certification Scheme (KPCS). Those nurseries currently fully certified will continue to be described as producing KPCS Full Certification plants. However, those nurseries that currently hold Within Region certification will now be referred to as producing KPCS Restricted Certification plants. There will be a two-week implementation period for nurseries to transition to any new branding.


The KPCS itself is to be reviewed, with a view to aligning biosecurity risk management policies for all plant material.  This will help ensure biosecurity resilience and robust plant movement traceability. KVH will keep growers and nurseries updated as the review progresses.

Add the chill calculator to your weather risk toolbox
12 July 2018

The Psa Risk Model is an online, weather-based decision support system, that assists with orchard management in a Psa environment. It includes actual weather station data and weather forecast details to provide customised access to unique disease information and interpretations that help growers target low risk periods for orchard activities such as pruning and grafting.

Ten-day forecasts can be viewed. Looking ahead Northland, Auckland, Coromandel, Waikato and Katikati have severe risk forecast for at least six of the next 10 days while the Bay of Plenty, Gisborne and Hawkes Bay weather stations typically predict three or four days of severe risk. Overall though, across the country the risk seldom falls below moderate and growers should ensure good hygiene practice is in place to reduce the risk of infection transfer across orchards.

Growers are also reminded of the easy to use winter chill unit calculator available on the KVH website (accompanied by a short online video demonstrating what it can provide). This calculator allows growers to check how winter chill is progressing and compare chill hours across the past four years for a range of weather station locations.

Click here to access the KVH weather tools. Please note, growers must be registered with the KVH website to use the tools – if you haven’t already done so, please register now.
