Prevent pampas from flowering NOW
7 February 2019

The invasive South American plant, pampas, will very shortly be sending up flower heads.  Pampas flowers in late summer and autumn months and can be a significant problem for kiwifruit crops, in that the thousands of fine, wind-blown seeds produced from each flower head can attach to fruit.  This seed contaminant is a reject factor and may prevent fruit access to some overseas markets.  Ensure that any pampas plants adjacent or near a kiwifruit orchard are destroyed.  There was a huge spike in the number of pampas seed detections on kiwifruit last packing season.

Refer to this previous Bulletin article for information on controlling pampas and identifying differences between South American pampas and the native toetoe.

New biosecurity advisor: Erin Lane
7 February 2019

KVH is pleased to announce the appointment of Erin Lane as Biosecurity Advisor.

Erin comes to KVH from the Ministry for Primary Industries (MPI) where she held various roles over her seven years there. She began as a Quarantine Officer in Auckland, working at the port, airport, mail centre and transitional facilities inspecting and clearing imported goods. Erin also worked as an Incursion Investigator, an Adviser in the Readiness and Response team, and an Adviser in the Regulation area, working specifically on Brown Marmorated Stink Bug (BMSB) regulation.

Most recently, Erin has worked in Japan with the vehicle industry on educating and promoting better biosecurity practices, and more specifically, BMSB management across their supply chain to ensure that the risk posed by this unwanted pest remains offshore.

Erin brings with her biosecurity expertise and experience, with a sound understanding of biosecurity policy, standard setting and risk analysis. In her role at KVH, she will be focussing on maintaining accurate and up to date pest lists to help prioritise readiness efforts. She will be working closely with growers and the wider kiwifruit industry to ensure awareness of biosecurity threats, to support the industry to manage any biosecurity risks, and to help increase the industry’s level of overall biosecurity preparedness.

Fight against devastating disease begins
7 February 2019

New Zealand’s horticulture and wine industry groups have been awarded a Sustainable Farming Fund (SFF) grant to progress research into an invasive and unwanted plant pathogen spreading overseas. 

Xylella fastidiosa, currently leaving its mark across Europe and the USA, could have devastating consequences for many horticultural industries, New Zealand’s culturally important plants and private gardeners should it arrive here. 

While kiwifruit is not a reported host of Xylella, KVH is supporting this research effort to give us greater certainty of our status and increase our level of preparedness.

The SFF project proposes a phased approach to better identify the risks posed by the pathogen to New Zealand’s primary industries and enable development of a cross-sector approach to preparation and response should it be found in New Zealand.

During the first phase known and potential impacts on a range of New Zealand’s crop and significant taonga species will be identified, as well as insects with the potential to vector spread.  Phase 2 will focus on education and awareness to highlight findings and their implications. Phase 3 will then focus on developing research priorities to be progressed through a cross sector Operational Agreement for the pathogen under the Government Industry Agreement for biosecurity readiness and response (GIA).

The project is likely to begin early this year and will be completed within 12 months.

The Xylella Action Group was formed in early 2018 under the framework provided by GIA. Membership comprises representatives from many industry groups and organisations including KVH, NZ Apples and Pears, NZ Avocado, B3, Dairy NZ, GIA, HortNZ, MPI, New Zealand Citrus Growers, NZPPI, New Zealand Winegrowers, Summerfruit NZ, Te Tira Whakamātaki, TomatoesNZ and Zespri.

Lessons from offhsore in BMSB management
7 February 2019

While Brown Marmorated Stink Bug (BMSB) is not established in New Zealand, our focus is on preventing it arriving here and acting swiftly to eradicate it should it be detected. However, KVH and Zespri are also preparing for how the pest would be managed within kiwifruit orchards if it were to establish here.

As part of these preparedness efforts Zespri recently organised a global BMSB teleconference to hear about impacts, management approaches and research efforts across global production areas. Updates were provided from Italy, China, France, USA, and a research update from New Zealand.

In Italy, BMSB has been present since 2012 but is so far restricted to northern areas. Damage to horticulture has been reported since 2015 with peak damage to kiwifruit production being July and August (leading up to harvest). Bugs are typically found in the morning, at the top of vines, near orchard borders. Growers are setting up nets on the borders of their orchards, using hail nets above and on the sides. This type of netting is considered cheap and relatively effective in reducing impacts to crops, but not eliminating damage altogether as the smaller BMSB nymphs (but not adults) are still able to enter through the mesh. Some growers are experimenting with smaller 2.2mm mesh to provide greater exclusion at keeping the bugs out. Studies are underway in Italy to better understand the use of trap crops, and whether a certain combination of sacrificial crops grown in close proximity to kiwifruit can provide a window of protection until kiwifruit are harvested.

In China, BMSB populations are at their peak just before harvest, as has been noted in Italy. Other research projects underway here have confirmed BMSB has an impact on storage quality as fruit softens more quickly, and orchards with the worst damage need to remove fruit from coolstore earlier as storage life is shortened.

In France, BMSB has only recently been detected in 2018, but already impacts to horticulture are being observed. The use of hail netting around French orchards is now considered best practice, with insect proof netting even better if possible. Researchers have compared Rescue (reusable hanging lure) and Fisher (pyramid shaped lure that sits on the ground) pheromone traps and found that the Rescue type seems to do better with catches peaking in August - in line with general population peak - for both adults and juveniles.

In the USA, a gold kiwifruit grower based in Alabama estimated that fruit loss attributed to BMSB may have been around 50%. Again, numbers of the bug peaked just before harvest (August and September). Traps have been used and caught up to 100 bugs a week. The grower has experimented with trap crops (sorghum, sunflower, corn, soybean, cotton) as well as gardens around the crops. All have shown some potential, but none have successfully controlled BMSB numbers. Chemical trials of products permitted for use on kiwifruit have demonstrated a limited effect.

KVH and Zespri will continue to get updates from across global production areas and share information with growers so that as an industry, we can implement practices that will reduce impacts in the event of a BMSB population being found in New Zealand.

BMSB is the current focus of many research projects within our Kiwifruit Biosecurity Research Portfolio and amongst aligned research providers. At a national level under the BMSB Council (with the Ministry for Primary Industries (MPI)) this is mostly focused on improving preparedness for a response to increase the likelihood of eradicating this pest, or reducing numbers to a level that will reduce subsequent impacts to New Zealand.

Support talented young horticulturalists
7 February 2019

Head along to the Bay of Plenty Young Fruit Grower competition at the Te Puke A&P Show this weekend in support of the up-and-coming horticulturalists vying for the title.

Eight competitors, known for their passion for the industry and exciting futures, will battle it out in a series of theoretical and practical horticultural activities designed to test contestants in a competitive, fast-paced environment. There will also be a biosecurity quiz round run by KVH who will be at the A&P Show all day on Saturday to answer any questions you may have about the work we’re doing to keep unwanted pests and diseases from establishing within our kiwifruit orchards and communities.
