First Psa exudate heralds spring
23 August 2018

KVH has received reports of Psa exudate in Gold3 vines from Gisborne, Edgecumbe, and Maketu sites this week. As sap begins to rise symptoms of Psa will begin to appear and growers are recommended to monitor areas more prone to Psa to be sure they have a good understanding of where risk lies this season. If ground conditions have limited the opportunity to apply copper through winter, now is the time to apply a spray, ensuring a one-week window is maintained between bud enhancing spays and copper.

Where pruning gangs are still at work an emphasis on tool hygiene is also recommended. Reports of fresh Psa exudate associated with autumn girdles suggests infection may be related to poor tool hygiene (patterns of consecutive plants within rows affected is being observed).

Tighter import rules to stop stink bug
23 August 2018

KVH continues to advocate strongly on behalf of the industry for strict biosecurity border controls and backs Ministry for Primary Industries (MPI) action around new treatment and cleaning rules for imported vehicles and machinery, which will make it harder for Brown Marmorated Stink Bugs (BMSB) to make their way across our borders.

The updated Import Health Standard (IHS) comes into force 1 September and has a focus on Japan following biosecurity issues earlier this year with contaminated vehicle carriers. There are also new restrictions on imports from many European countries, where the stink bug is rapidly spreading.

Under the Standard:

·      14 more countries have been added to the list requiring mandatory treatment of vehicles and machinery during the stink bug season. This requirement previously only applied to vehicles from the United States and Italy.

·      Used imports from Japan will need to be both treated and cleaned offshore as part of an approved system during the season.

·      All other new and used imports (during the stink bug season) from other countries covered by the standard will need to be treated or go through an approved system.

·      Vehicle manufacturers will have the option of applying to MPI for biosecurity approval of their supply chain processes, avoiding the need to treat each new unit. This involves having strict controls in place to reduce the risk of contamination.

·      Used machinery from any country must have a certificate proving it has undergone thorough cleaning and treatment before arrival in New Zealand. There must be evidence the machinery was disassembled for cleaning. It must also arrive with a sticker showing how and when it was treated.

·      MPI can approve alternative treatments, but only if there is proof they can produce the same outcome as the approved methods.

Psa research update
23 August 2018

Around 80 growers and technical reps attended the KVH/Zespri-run Psa research update held at Baypark this week.

Growers heard from speakers who outlined the latest progress on several research projects currently underway, including copper and other product resistance and the breeding programme.

Paul Hassan from Syngenta outlined systemicity and crop safety of Actigard, and Stephen Hoyte presented on Aureo Gold, a yeast-based product currently moving towards registration as an additional Psa product.

Attendees were also given an update on the GoldFutures project by Stephen Hoyte from Plant and Food Research. This project recommends “best practice” Psa management backed by findings from 10 Gold3 orchard pairs across six growing regions. Frost and budrot projects as well as a review of the possible role of guttation in the disease cycle were also presented providing good insight into advances in our understanding of Psa.

A summary of the meeting along with the presentations and a video taken on the day will be available on the both the KVH and Zespri canopy websites soon.

Purchasing plants?
23 August 2018

KVH has been made aware of the theft of kiwifruit plants from a nursery recently. We remind all growers that only Kiwifruit Plant Certificaton Scheme (KPCS) certified plants should be sourced, from KPCS nurseries. All plants come with dispatch records from the nursery, including batch information which is vital for traceability in the event of an incursion. These should be filed with GAP records.

For growers wishing to purchase plants, there is a list of nurseries who have met the KPCS Full Certification requirements on the KVH website. Restricted certification plants are available from nurseries named in the Restricted Certification Nursery List. These plants can only go to Psa-V positive orchards.

EPA approves Samurai Wasp application
23 August 2018

KVH, the Ministry for Primary Industries (MPI) and other members of the New Zealand horticulture industry have welcomed the Environmental Protection Authority’s (EPA) decision allowing the release of the tiny Samurai Wasp into New Zealand, if ever there is an incursion of the Brown Marmorated Stink Bug (BMSB).

The outcome is a major milestone against one of the greatest threats (should it occur) to New Zealand’s kiwifruit, horticultural industries and urban communities, and was made possible with the support of growers and industry groups who alongside KVH, made submissions and presented their views to the EPA during the consultation process. This was an excellent effort and we thank all those who contributed to the process. Of the 69 submissions made in the consultation process 24 were from the kiwifruit industry in support of this application.

The Samurai Wasp is the size of a poppy seed and completely harmless to humans and animals except stink bugs. It is a natural enemy of BMSB; the female wasp lays her eggs inside those of the stink bug, killing the nymph in the process. Studies overseas have shown that the wasp can destroy over 70 percent of the eggs in a stink bug egg mass. It also provides an opportunity to be proactive in our approach and gives us another tool we can use to manage the stink bug. Permission to release the wasp will be subject to a number of strict controls that will dictate when, where, and by whom it can be released. Biocontrol agents are normally sought once pests become a significant problem. This is the first time that we are aware of where a biological control has been approved before a pest has established

The application seeking permission to release the wasp in the event of an incursion 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). Read the media release announcing the decision here.

Spotted Lanternfly - the next big threat?
23 August 2018

Pennsylvania, USA, is currently dealing with an incursion of Spotted Lanternfly (Lycorma delicatua), and the information coming from this region is concerning. The numbers that this pest is building to may even exceed Brown Marmorated Stink Bug (BMSB). It results in large amounts of sooty mould growth, is a prolific hitchhiker and has a large host range that includes kiwifruit. Spotted Lanternfly is a known kiwifruit pest in its native range of China, but like many pests it appears far more damaging as an invasive pest with no natural predators to keep population numbers in check.

As part of his recent Nuffield Scholarship travels, KVH Director Simon Cook visited Pennsylvania where the SLF has been found and is proving to be harmful to a wide range of crops.

“I spent some time in one of the worst hit spots in the state, and even the local entomologist himself commented this was the most invasive pest he has ever seen - given they have been through Brown Marmorated Stink Bug (BMSB) and Spotted Wing Drosophila (SWD) incursions that is a pretty telling statement. They’re seeing heavy infection and feeding on a wide range of fruit and vegetables, and the damage being done is so severe that it is thought to be the cause of grape vines failing to survive winter.” 

“Unfortunately, SLF wasn’t picked up in Pennsylvania until a significant population had already established, making ongoing eradication attempts difficult. There is some relatively good news though, in that a second US incursion in Virginia suggests if we identify SLF early before a large population is present, we have a real chance at eradication. This incursion is around two to three years old now and is still limited to a small one-mile radius area, so it does take time for numbers to build, providing good control opportunities.”  

KVH is taking this advice onboard and has included SLF as a feature pest in our upcoming calendar for front line staff at the port and transitional facilities and have included it in a review project to better understand the potential threats to our industry and how we may manage it. The Ministry for Primary Industries (MPI) is also well aware of this threat and while there haven’t been any border interceptions to date, the risk of SLF would increase if this pest continues to expand its invasive range across the US.

Growers may also be interested to read more about this pest in a feature article in the New York Times.

Do you watch Border Patrol? If you do, did you ‘catch’ the new addition to the title screen? You’d have to be quick, they were off screen in a ‘snap’ but the team at the Ministry for Primary Industries (MPI) ‘report’ they worked with the shows production company to add the unwanted extras for this season to help raise awareness of priority items our border patrol agencies are looking out for.

Full label claim for Kasumin
23 August 2018

Kasumin has now gained a full ACVM registration label claim for Psa management.  Kasumin is included on the KVH recommended product list and works as a preventative bactericide. The active ingredient kasugamycin has a bactericidal mode of action that is different from other bactericides such as streptomycin. Kasugamycin is active against pathogenic fungi and bacteria in plants and has never been employed as a human or veterinary medicine.

Kasumin must be used in a programme with other plant protection products that are active on and recommended for the management of Psa and should be reserved for use in high-risk situations. One pre-flower Kasumin is allowed under Crop Protection Standard rules, with a second application requiring a JA (Justified Approval). Follow user guides.

Learnings from BMSB research underway
23 August 2018

Watch a hot off the press video from Italy to get an insight into the work being undertaken to study and learn about the Brown Marmorated Stink Bug (BMSB).

Professor Max Suckling from Plant and Food Research and the Unversity of Auckland is working with local colleagues in Italy, where this pest is going through an outbreak affecting kiwifruit, apples, pears, corn and other crops.

As you can see in the video the group are studying a range of interesting things about BMSB, including sound communication (these bugs use low frequency sound to communicate with each other, which the team are trying to redirect and use against the bugs to disrupt mating, in a similar concept to how pheromone traps work for other pests), sterile insect techniques for control, behaviour at different life stages, and how the public can get involved in mapping location and numbers of the bug using cell phone apps.

The damage Professor Suckling talks about this bug doing to the wide range of crops it affects is a reminder of why we must continue to do all we can to keep it out of New Zealand. Read more about BMSB on the KVH website.
