Spring brings stirrings of Psa-V
20 August 2015

KVH has just completed a monitoring round of Gold3 and Hayward vines across the Bay of Plenty, including orchards from Maketu, Edgecumbe, Waihi and Opotiki.

Cane dieback and fresh exudate (often from multiple points) were obvious on many male vines and some female vines. Reports of similar symptoms have been received from Waikato and Katikati orchards.

MPI ramps up biosecurity for air passengers
6 August 2015

New biosecurity measures will be introduced by the Ministry for Primary Industries to make it tougher for air passengers to bring goods into New Zealand that could carry pests or diseases. The measures are the result of new biosecurity funding from the government’s 2015 budget.

The planned new biosecurity measures include:

  • Introducing 20 new biosecurity detector dog teams.
  • Introducing five new x-ray machines.
  • Trialling a mobile x-ray machine that can shift to different sites.
  • Greater ability to increase the level of biosecurity intervention for air passengers according to risk.
  • Introducing specific communications to target passengers more likely to carry Queensland fruit fly host materials.

Spiders in Mexican grapes may change import rules
6 August 2015

Import requirements for Mexican grapes may change following the detection of a black widow spider by a member of the public in some Mexican red seedless grapes.

More than 20 spiders were subsequently detected in imported Mexican grapes around the country.

MPI has an investigation underway and the results may see changes to the import health standard requirements. However it is too early to confirm what course of action MPI will take.

In the case of Mexico grapes, current requirement is for MPI officers (based in Arizona) to verify the fruit is free of pests, as certified by the Mexican government.

If regulated pests (including spiders) are detected, the consignment is not allowed to be exported. MPI has been fumigating all imports of this season’s Mexican grapes at the border since the discovery of the spiders.

MPI gives grower overview of border clearance services
6 August 2015

MPI’s Director of Border Clearance Services, Steve Gilbert, recently gave an overview of the very real biosecurity challenges New Zealand faces at the border to KVH members at its AGM.

Steve also outlined what MPI is doing to mitigate these risks and highlighted the critical role a working partnership between government and industry through GIA plays to support this.

Some key points from Steve’s presentation:

  • The world is rapidly evolving and our biosecurity system must adapt with it
  • The current system won’t be enough in the next 5-10 years
  • Air and cruise ship passenger numbers are increasing (air +23% and cruise ship +5% by 2021), trade and freight is increasing (+41% by 2021) and express freight volumes are increasing (+33% by 2021)
  • These increases escalate the risk at the NZ border
  • The border clearance levy comes into effect on 1 December 2015 – providing a revenue base to fund increasing passenger numbers
  • The level of effort and intensity by MPI is increasing to help mitigate border risks. This includes more x-ray inspectors, mobile x-ray, increased auditing of pest free areas in Australia, more detector dogs used throughout airports and the border clearance levy

R&D reports: 2014-15 potted plant trial results
24 July 2015

Elicitors on Gold3 potted plants, January to March 2015
Field trials on potted Gold3 plants tested efficacy of a range of elicitors in inducing a plant immune response to Psa. TNL3454 (at higher concentrations) and AB48414 showed a level of Psa control comparable to Actigard™ for up to six weeks post-Psa inoculation. Citrox BioAlexin showed some significant Psa control four weeks post inoculation. This product could offer organic growers an elicitor option. However, further trials to prove consistent efficacy would be advisable. ProAct and Silver combined and Luna Care did not show efficacy.

Psa control products on Bruno potted plants, December 2014 to January 2015
Field trials on potted Bruno plants further tested the efficacy of a range of potential Psa protectants. At the recommended concentration, Nanospada significantly decreased leaf spotting for up to three weeks post Psa inoculation. When diluted, Nanospada had no significant effect, supporting the use of the recommended rate. Another product, TNL3214, significantly reduced leaf spotting throughout the trial. KOF products only provided control when combined with Streptomycin.

Introducing the Biosecurity Steering Group
24 July 2015

KVH and Zespri have established a Kiwifruit Biosecurity Steering Group with a goal of reducing the risk and impact of biosecurity incursions to the kiwifruit industry.

Consisting of members from KVH, Zespri, Plant and Food Research, Scion, Avocados New Zealand and the Ministry for Primary Industries (MPI), the steering group will identify knowledge gaps and prioritise research needs relating to kiwifruit biosecurity threats not yet established in New Zealand.

Associated with the steering group is the newly established Kiwifruit Biosecurity Research Portfolio. The portfolio is funded by the KVH biosecurity levy with matching contributions by Zespri and managed by the Zespri Innovation team.

The Biosecurity Steering Group will prioritise research to meet the following objectives;

  • Develop a greater understanding of the biosecurity threats to the kiwifruit industry;
  • Develop tools to reduce the likelihood of establishment and impact of these biosecurity threats, which includes tools for diagnostics, surveillance, eradication and management;
  • Pathway analysis to understand where gaps may occur in the biosecurity system and take a collaborative approach with the Ministry for Primary Industries to address these.

More information about the new Biosecurity Steering Group will be provided in the next Kiwifruit Journal article.

Brazilian fungal disease high priority for Biosecurity Steering Group
24 July 2015

Ceratocystis fimbriata is a fungal pathogen causing wilt disease in a number of plant species, including kiwifruit where significant impacts have been reported in Brazil in recent years.

The serious potential impacts of Ceratocystis fimbriata and the lack or kiwifruit specific research being done elsewhere makes this a high priority organism for Kiwifruit Biosecurity Research and is on KVH’s Most Unwanted List.

Ceratocystis fimbriata projects within the Kiwifruit Biosecurity Research Portfolio include:

  • Pathogenicity testing of the New Zealand kumara strain of C. fimbriata. Fortunately the results of this project shown that the New Zealand strain is not pathogenic to kiwifruit and therefore our efforts can be focused on keeping new pathogenic strains outside of New Zealand.
  • A comprehensive literature review by an international expert to specifically understand the risks and potential impact of the pathogen to the New Zealand kiwifruit industry. This review has significantly improved our understanding of C. fimbriata.
  • The next project will sequence a number of Ceratocystis strains to develop primers that will advance our ability to keep pathogenic strains out of New Zealand and provide a tool to diagnose infected vines should the pathogen establish.

A Ceratocystis fimbriata fact sheet can be found on the KVH website here.
