Beware of the Spotted Lanternfly: Chasing News, New Jersey, speaks to an official from the local Department of Agriculture about the severity of the threat and what the state is doing to protect produce.

Australia saves NZ from billion-dollar stink bug invasion: A ship bound for New Zealand has been stopped in Australia after it was found to be carrying stink bugs. The ship, the Armacup Triumph, was intercepted in Australia and has been sent offshore. The Triumph had been instructed to anchor at sea and has since been ordered to return to China.

Cargo ship ordered to leave New Zealand: biosecurity officers intercepted live and dead stink bugs on a vehicle carrier in Auckland yesterday, and have directed it to leave New Zealand waters for offshore treatment before it can return.

Partnership approach pays off: KVH Chief Executive, Stu Hutchings talks with Rural News about how the organisations partnership approach has ensured the industry is better placed for any biosecurity event.

Quick survey to have a say
29 November 2018

We’re running a short survey about the ways in which we share information with you, and how often.

We’re working to raise awareness about good biosecurity practice, the benefits these can bring, and the potentially devastating impacts of another incursion on our orchards. In doing this, we need to learn more about the ways you prefer us to keep in touch with you and how we can get important information under your nose.

This survey will give us a clearer picture of what we should do more of and what we should do less of so that we’re better serving growers by providing the information and resources needed.

Your views are important – please take part (it will only take a couple of minutes to complete) and help us work together to continue protecting New Zealand’s kiwifruit industry from unwanted pest and disease threats. Complete the survey here.

The survey closes 5pm Monday 3 December 2018.

All responses are anonymous and will be kept confidential to KVH.

Springing into BMSB season
29 November 2018

With spring well underway summer is now knocking at the door, as is the Brown Marmorated Stink Bug (BMSB) threat to New Zealand.

Every summer KVH, alongside the Ministry for Primary Industries (MPI) and other industry groups through the GIA partnership, goes on high alert to keep this stinky pest out of New Zealand. This year is no different. As always, engaging the general public to join in the fight against BMSB is key and so the annual nationwide awareness campaign to remind everyone to keep watch for this potential invader is underway.

The advertising highlights how the bugs can infest homes and gardens and stresses the public nuisance of BMSB establishing in New Zealand. It encourages everyone to get involved and be our eyes. As well as the general public, we’re also continuously reminding those who might encounter a hitchhiking BMSB – including growers, pack houses, transitional facilities, airport staff, and importers.

The campaign is running ads online, in magazines, greeting arrivals at airports, and displaying posters in garden centres. Plus, we’ll again be using Ruud ‘the bug man’ Kleinpaste as a BMSB spokesperson across social media and interrupting viewers on news media services.

Remember to keep an eye out on your property, on your plants, your vegies, your fruit – and anywhere in your garden. It’s about the size of a 10-cent coin and is noticeable by its black and white banding on the antennae and abdomen. If you think you see one, catch it, take a photo and call the Biosecurity New Zealand pest hotline on 0800 80 99 66.

On the lookout for fruit fly
29 November 2018

There were a couple of fruit fly finds at the border during October. One interception was of Oriental Fruit Fly eggs on a consignment on papaya being imported, and another was of Fijian Fruit Fly larvae found on a guava placed in an airport amnesty bin.

There have not been any interceptions of the Queensland Fruit Fly this high-risk season. 

You can
read more in the latest monthly KVH risk update, which includes data reported by the Ministry for Primary Industries (MPI) and information about what’s happening in other countries to manage the threat posed by fruit flies.

Remember: the high-risk period for fruit flies runs through to June. Be vigilant, keep watch, and if you hear of someone that has accidently bought fruit or vegetables into New Zealand make sure it is reported to MPI and then appropriately destroyed (bagged and put in the rubbish is the best way, not composted).

Biosecurity across Tauranga Moana
29 November 2018

KVH attended a Tauranga Moana Biosecurity Capital (TMBC) meeting yesterday, the first get-together since the successful Biosecurity Week for the region in October.

At the meeting KVH discussed activities the kiwifruit industry and growers contributed to during the week, and how KVH plans to continue to have a lead role in this first-of-a-kind regional initiative. Discussions focused on finalising a three-year plan for the initiative that specifically aims to lift biosecurity awareness and advocate for better biosecurity for the region.

There are now over 20 local businesses, organisations, and education providers that have signed up to the initiative and are working together to take collaborative action towards biosecurity excellence involving the whole community. Read more about TMBC and its connection to Ko Tatou This Is Us, on the KVH website.

A plant pathway for all regions
29 November 2018

Regional boundaries and classifications are important to protect areas with little or no Psa and manage risk from new or evolving forms of the disease. Following consultation with growers, KVH has released a new pathway standard that will continue to manage this risk, but also enable more growers to access kiwifruit plant material, especially new varieties.

The standard provides a robust, and strictly controlled pathway that allows material from Recovery regions to be moved to Exclusion or Containment regions, with little to no increase in Psa risk.

Based on tissue culture, the pathway contains several different measures to mitigate risk over an 18-month period that reduce this risk to an acceptable level. An independent review of the pathway was undertaken by Scion Research found the pathway would result in negligible increase of risk in introducing Psa to these regions. Recommendations made in the review have also been adopted within the pathway.

The role of KVH is to develop a pathway and ensure risk is sufficiently managed. The movement of plant material, and costs associated with this process will now be borne by commercial parties, of which Zespri and Plant & Food Research have expressed an interest.

The standard has effect from now and any qualifying plant material for movement can be notified to KVH to begin the process of using the pathway.  If you have any questions, please email info@kvh.org.nz or phone KVH on 0800 665 825.

Tough Psa conditions for some Hayward sites
29 November 2018

For many later flowering Hayward sites, recent wet weather following on from periods of damaging wind has resulted in a rapid rise in leaf spot symptoms.

Leaf spot and flower bud infection points will continue to add to the inoculum load through high-risk weather periods and affected growers are recommended to apply coppers at summer rates as soon as flowering is through to help manage risk. If there are young plants or grafts in these blocks make sure nozzles are directed to ensure these also receive good coverage. Take care to only apply copper sprays in good drying conditions.

Pruning of males should be reserved to dry periods and with close attention to tool hygiene between vines to avoid infection transfer, and particularly where infected canes are also being removed. The risk model indicates ongoing moderate risk from most stations over the next week so take every opportunity to prune in the dry and follow up with spray. Apply wound protectants to all large cuts.

KVH makes decisions and bases advice on key research learnings, industry knowledge and experience.

The scientific research publications that drive our policies and management advice are added to our website as they are finalised. Growers are encouraged to look them up and have a browse of the many different reports we make available.

Recently added:

·         A paper on fruit quality attributes for Hayward and Gold3 kiwifruit treated with Aureo Gold during flowering and fruit set 2017/18. View the report here.

This trial with Aureo Gold investigated the impact the applications have on components of yield and fruit quality. The results showed that Aureo Gold did not have negative impacts on components of yield or fruit quality parameters at harvest or postharvest.

·         A paper on efficacy of Novel Elicitors on Psa. View the report here.

This trial was established to investigate the field efficacy of several promising elicitors, as identified in potted plant trials, to control Psa.

All go for Aureo Gold
29 November 2018

New Psa product Aureo Gold is now registered for use on kiwifruit and has BioGro certification.

Limited stock of Aureo Gold was available for 2018 and growers are advised to check with their nearest retailer to determine future availability.

Just approved by the Agricultural Compounds and Veterinary Medicines Group (ACVM), Aureo Gold was discovered and isolated from an Otago apricot by Plant & Food Research scientists and since then extensive field trials have demonstrated its protectant efficacy.  Research suggests this product has multiple modes of action, including: 

·         physical disruption of Psa cells on leaf surfaces that appears to affect the ability of Psa to colonise stomata,

·         acting as an elicitor activating kiwifruit host defence genes, allowing the plant to react more quickly and to a higher degree to the presence of Psa. 

Research to date also indicates that Aureo Gold doesn't produce anti-microbial compounds, and therefore resistance development is unlikely.

In trials on Hayward vines, Aureo Gold gave similar levels of protection from leaf spotting as Kocide Opti in the 2017/18 season.  The image above shows Aureo Gold's protectant ability in potted plant trials. The leaf sprayed with water on the left, and a leaf sprayed with Aureo Gold on the right were then inoculated with Psa, with resultant reduction in leaf spotting symptoms.

Aureo Gold can be applied from budbreak to six weeks after flowering, at seven to 14-day intervals whenever Psa protection is required. It’s use period for this season is closing (this and its short shelf life means there is limited stock at the moment) but trials have indicated good crop safety when applied throughout the flowering and fruitset period.

How to use Aureo Gold:

·         Good coverage is critical and the use of an adjuvant such as DuWettt or DriftStop is recommended. 

·         Apply at 50g/100L of water, in 600-1000L/ha. 

·         Don't apply more than 4.5kg active ingredient per hectare, with a maximum of 10 applications per hectare per season. 

·         Check the label for compatibility information – don’t use in a mixture with copper.  

Limited stock of Aureo Gold was available for 2018 and growers are advised to check with their nearest retailer to determine future availability. Aureo Gold will be available for order through Farmlands, Fruitfed Supplies and Horticentre. It comes in a 1kg pack and has a shelf life of 4 months when stored in a cool dry place below 25 degrees Celsius.
