KVH Chief Executive, Barry O’Neil, has recently been appointed to the HortNZ Board as an Independent Director. Barry has extensive biosecurity governance experience, including membership of Australia’s National Biosecurity Committee and directorship of the New Zealand Bio-Protection Core and SCION.
KVH is looking for a person to inspect harvest bins at a Pukekohe packhouse to ensure they are free of leaf/plant material before they are delivered to Exclusion region orchards.
Work is part-time and on an on-call basis throughout April and May.
For further details phone Karyn Lowry on 027 227 1157 or email email@example.com
KVH has recently received several reports of unusual symptoms on kiwifruit orchards by proactive growers. These have been followed up with site visits and diagnostic testing to determine the cause. Fortunately these investigations have not found any new pathogens or biosecurity threats.
If a new pathogen were to enter New Zealand and affect our industry, swift action would give the best chance of minimising impacts to the industry.
All growers are encouraged to report any unusual symptoms to either KVH (0800 665 825) or their postharvest technical representative.
This week MPI announced changes to the movement controls for fruit and vegetables in the QFF Controlled Area in Grey Lynn.
These changes will enable customers to purchase fruit and vegetables from MPI-Approved Retailers within the Controlled Area that they can take outside of the Controlled Area.
Precautions are required by both MPI-Approved Retailers and customers when purchasing and selling fresh produce to avoid potentially spreading Queensland fruit fly.
These precautions include:
People will be able to identify approved retailers in the Controlled Area as they will display this MPI poster.
A list of approved retailers is also available on MPI’s website here.
Some members of the public have asked why we are so concerned about fruit flies when we see these all the time hanging around our compost bins.
Queensland fruit flies (QFF) are different from small dark brown drosophila flies (also called vinegar flies or ferment flies) that hang around ripe and decaying fruit.
The QFF is around 6–8mm in length and is brown marked with yellow. A vinegar fly is much smaller, around 2mm in length (smaller than a common sand fly).
Most drosophila flies are not agricultural pests. However, they can be a nuisance where fruit and vegetables are stored.
KVH has been working with the Bay of Plenty Regional Council to reduce the amount of wild kiwifruit establishing in the Bay of Plenty’s gullies, bush margins and production forests.
Wild kiwifruit is an environmentally damaging vine and may harbour Psa-V or other pests, which can then spread to nearby orchards. Reject fruit fed to livestock may be a potential seed-source of further wild vines, establishing when birds such as waxeyes feed on the softening fruit and distribute the seed.
A trial was undertaken by Kawerau-based Plateau Bark to see if compost could be made using reject fruit (and associated debris) mixed with pulp waste from the Norske Skog Tasman Ltd pulp and paper mill. The composted material was regularly turned and monitored. The trial was overseen by Plant and Food Research.
Temperatures within the compost piles were logged and found to be regularly above 60 degrees Celcius. Testing confirmed the end product was Psa-V ‘not-detected’ and kiwifruit seed had been destroyed during the high-temperature composting process.
KVH is now advancing the process to name Plateau Bark as a KVH-approved compost manufacturer using reject kiwifruit. Ongoing approval will depend on the compost product being consistently manufactured to prescribed standards, regularly monitored and free of Psa-V, other harmful pathogens and viable kiwifruit seed.
The relevant KVH Protocols will be amended to allow KVH-approved compost manufacturers to spread compost containing reject fruit, made to prescribed standards, onto Psa-V positive orchards in Recovery Regions.

All nurseries that sell and distribute kiwifruit plants are required to register with KVH on an annual basis. Non-registered nurseries or nurseries that have let their registration lapse cannot dispatch kiwifruit plants. A list of KVH-registered nurseries is available on the KVH website here.
To avoid supply shortages, growers need to order plants well in advance so nurseries can anticipate industry demand. Plants ordered for dispatch after 1 October 2016 must be certified under the Kiwifruit Plant Certification Scheme (KPCS).
Growers also have an obligation when purchasing plants to ensure the nursery is registered and movement controls are complied with. If you have any concerns about the plants you are purchasing this season and/or the movement controls associated with them, please call KVH to check first – 0800 665 825.
KVH Protocols state that kiwifruit plant material (budwood, pollen, rootstock etc.) and other risk items (harvest bins) must be securely covered when moving between sites/regions to reduce the risk of disease spread. Nursery plants are also required to be sprayed with copper prior to dispatch and tested for Psa-V within six weeks of movement occurring.
KVH Protocols provide protection for transit regions that have limited Psa-V infection or where Psa-V has not yet been detected.
If you are planning on moving plant material or other risk items, please check the KVH Protocols on the website. If you are unsure please give us a call – 0800 665 825.
The 2015 Psa-V Seasonal Management Guide is now available on the KVH website – click here.
This new guide provides a basis for growers to build their individual Psa-V Orchard Management Plans for the coming season.
The 2015 guide incorporates year-round advice for managing Psa-V. Previous Seasonal Management Guides have been split into Autumn/Winter and Spring/Summer seasons.
Good management of Psa-V through autumn helps minimise disease levels seen in the following spring.
The response to the Queensland Fruit Fly outbreak in Auckland has now been operating for more than a month and is likely to continue for many more.
Field work, including intensive trapping, baiting and fruit collection and sampling also continue.
To date, 14 adult fruit flies had been found within the controlled area; and fruit fly larvae had been found in five separate properties within very close proximity of each other.
The infected properties continue to receive intensive ground treatment for fruit fly, including targeted foliage spraying and the use of insecticide granules. The ground surrounding the trees where larvae were found has been thoroughly sprayed and sealed with a polythene plastic cover (pictured above).
Any future developments will be communicated through the KVH website.
Ceratocystis fimbriata is a fungal pathogen that is causing significant damage to kiwifruit orchards in Brazil, with some growers reporting 50% vine loss over the past five years.
The sudden appearance of this pathogen in kiwifruit in Rio Grande do Sul, Brazil is considered particularly alarming as kiwifruit is highly susceptible and the production impacts of the pathogen threaten the viability of this industry in Brazil. There have been no reports of impacts to kiwifruit from this pathogen outside of Brazil to date.
New Zealand does have a strain of the C. fimbriata complex, causing black rot on kumara. Research is planned to determine if this strain is pathogenic to kiwifruit.
Control options against C. fimbriata have limited effectiveness and developing resistant or more tolerant cultivars is considered the best course of action to prepare for this pathogen.
A two year research project is being undertaken that will screen a number of C. fimbriata isolates, including the NZ and Brazilian isolates, for pathogenicity against a number of kiwifruit cultivars. This will allow the identification of:
Components of the research will be done offshore, however cultivar testing will require the Brazilian isolates to be imported into a New Zealand containment facility. Details on how the pathogen will be contained are provided in the document: Physical containment of plant pathogens.

KVH has made some improvements to the R&D section of the website to make it much more user-friendly. Growers still need to be logged in to view the full R&D section.
