Australia recruits Sunraysia growers in the fight against fruit fly
14 May 2015

Citrus, stone fruit and table grape growers in the Australian region of Sunraysia are being asked to take a role in eradicating Queensland Fruit Fly (QFF) from the region in an attempt to regain the region’s Pest Free Area status.

This is an innovative approach that involves growers deploying traps to monitor QFF presence/ absence and population numbers. These traps are separate from the official trapping system and serve as an indicator for when growers should apply management practices such as insecticide application, baiting and cover spray.

Sunraysia is an important horticultural region in Australia renowned for the production of high value crops. Invasive pressure from the QFF has resulted in the suspension of Sunraysia’s Pest Free Area status for QFF, meaning additional controls are now required for produce exported from this region.

MPI audit the greater Sunraysia pest free area
14 May 2015

In November 2014, MPI undertook an audit of Australia’s Department of Agriculture processes and procedures for managing the export of Mediterranean fruit fly and cucumber fruit fly host products from the Greater Sunraysia pest free area (PFA) to New Zealand. 

The audit also included reviewing the operation of cold treatment protocols for the export of Queensland fruit fly (QFF) host products from Sunraysia. As the Greater Sunraysia district is not currently a PFA for QFF, QFF hosts must be effectively treated prior to export to NZ. MPI recognises Sunraysia as a PFA for Mediterranean fruit fly (Medfly) and cucumber fruit fly.

MPI’s audit did not identify any critical situations in the system that would affect the risk of importing commercially produced fruit fly host commodities from the Greater Sunraysia PFA but made a number of recommendations for quality improvement. The recommendations mostly concerned documentation, dissemination of information about the fruit fly code of practice, internal audit and peer review processes.

Audits are part of MPI’s review activities of fruit fly management programmes with Australia and other countries to ensure an appropriate level of biosecurity risk management is maintained.

Australian horticulture get funding boost to fight fruit fly
14 May 2015

The Australian government has provided their horticulture sector with a funding boost of A$5.8m for two research projects. One project aims to deliver a farm-level support tool to assist growers with orchard activities, including early detection of pest and disease outbreaks; and the other project will look into area-wide management of fruit fly providing guidelines for efficient and effective pest suppression and stakeholder adoption.

Horticulture Innovation Australia, who are leading the projects, state that Queensland Fruit Fly results in losses of more than A$100m each year to Australia and is a major barrier to offshore markets.

PMAC fruit fly preparedness project
14 May 2015

As advised in a previous Bulletin, KVH and Zespri are members of the Plant Market Access Council (PMAC) fruit fly preparedness project. This project aims to pre-emptively agree market access conditions with key markets in the event of an incursion of a significant fruit fly species in New Zealand and minimise market access impacts.  Below is an update on the project.

  • A negotiating protocol for key trading partners has been developed which demonstrates how NZ will be able to export fruit fly-free product during a fruit fly incursion and/or if fruit fly were to establish here.
  • A scientific based model has been developed for inclusion in the protocol. The model calculates the key triggers that determine the status of the response by taking into account things like location – i.e. is the location rural or urban.

Negotiations with trading partners will begin once the protocol and the model are finalised and are likely to be a lengthy process. While some negotiations may take less than a year, it is possible that many of them will take longer. Ironically, it’s believed the response to the QFF in Grey Lynn this year may reduce the length of some of these negotiations. In some instances, information in the protocol was used during this recent response to liaise with key officials in some markets.

The negotiation process will be carried out in three stages based on the potential zones identified in an incursion response. Three different categories for negotiation have been identified:

  • Outside the designated control zone where export should be able to continue without any additional controls (phase 1)
  • Outside the controlled zone but passing through it to be exported and so requiring specific protection (phase 2)
  • Within the controlled zone requiring treatments to control any fruit fly (phase 3)

Once pre-emptive agreements are in place with key trading partners, these agreements should minimise market access impacts during a fruit fly response or incursion.

Working collectively to manage abandoned orchards
14 May 2015

There are now 108 abandoned orchards on the KVH register that have either been removed, or are in the process of being removed, since 2013.

KVH continues to work with land owners and regional councils to manage these orchards which pose a risk of Psa-V spread.

Over the last six months Bay of Plenty Regional Council has contributed $15,400 toward abandoned orchard removal costs in the region.

The removal of a 2.5 hectare abandoned orchard in Maketu was completed in April. The kiwifruit was planted adjacent to a chestnut orchard with vines smothering many of the chestnuts and willow shelter belt, killing many of the host trees.  The property Trust/owners and Bay of Plenty Regional Council assisted with removal costs.

Plans are progressing for the removal of two large abandoned orchards (totalling 4.7ha) near Ruatoria; and the removal of a one-hectare very abandoned orchard at Collingwood in Golden Bay is also progressing.  The kiwifruit vines and structures are heavily interspersed with mature ponga, mahoe and other native plants.

Representatives from KVH met with Prime Minister John Key yesterday when he visited the kiwifruit industry as part of a day-long visit to the Bay of Plenty.

KVH took the brief opportunity to talk to Mr Key about KVH’s recent areas of focus including the industry’s participation in the Queensland fruit fly response in Auckland, raising public awareness of the Brown Marmorated Stink Bug (BMSB) and our role in Government Industry Agreements.  Mr Key was particularly interested in the BMSB and its impact on primary industries should it establish in New Zealand.

Mr Key spoke to a crowd of around 200 industry people and acknowledged the biosecurity challenges New Zealand faces as a small trading country and the many ways biosecurity risks can come into New Zealand.

During the visit Mr Key also paid tribute to kiwifruit industry for its ability to recover in the wake of Psa-V.

Dont get complacent with Psa
14 May 2015

While Psa-V progression has slowed during the 2014-15 growing season in most regions, its important growers don’t become complacent with their Psa-V management, particularly as we head into winter.

A better understanding of managing the disease, combined with a fairly warm, dry growing season has resulted in a significant drop in Psa-V levels on most orchards.

However some orchards, particularly those in challenged locations, still have significant Psa-V pressure impacting on yields and orchard profitability. The photo above shows cane dieback and fruit shrivel on a Gold3 orchard in a challenged Waihi site.

This is a reminder that disease levels could quickly increase in any orchard as the weather becomes cooler and wetter, and if Psa-V is not proactively managed.

Immediately after harvest apply copper to protect fruit stalks. Using summer rates of copper will minimise leaf damage and is recommended if copper is being combined with Actigard™ as leaves need to be actively photosynthesising  for Actigard™ to be properly absorbed.  Where maintenance of leaf condition is less critical apply copper at winter rates. Do not apply Actigard™ to stressed vines.

All growers should be maintaining protective spray programmes in the lead up to winter and ensuring best-practice hygiene is carried out through the remainder of harvest and pruning. This will provide the best possible start for orchards next spring.

Harvest hygiene important in all regions
14 May 2015

As harvest progresses and resources become stretched, growers and harvest contractors are reminded of the importance of ensuring orchard hygiene standards are maintained. KVH has received calls from growers concerned that they are seeing standards start to slip.

The recent find of a streptomycin resistant strain of Psa-V, identified through the industry resistance testing programme, is a strong reminder of how new threats can arise and growers must stay on their guard to reduce risk of spread of disease.

Clean down areas with suitable sanitisers, and check to ensure no plant material is moved on or off the orchard through people or machinery remain important strategies in protecting orchards from incursions in all regions.

Compost using reject kiwifruit
14 May 2015

KVH has recently received a Plant and Food Research report about the trial of manufacturing compost using reject kiwifruit (and associated debris) mixed with wood pulp.

The report found the compost tested ‘not-detected’ for Psa-V and that kiwifruit seed was destroyed during the composting process. 

The Kawerau-based manufacturer is seeking to ramp up production of compost using reject kiwifruit, and to sell the product to primary producers, including kiwifruit orchardists, in the Bay of Plenty. 

KVH has amended its protocols around movement of compost containing kiwifruit material so an approval can be given to compost manufacturers on a case by case basis, as long as the product meets criteria including Psa-V not-detected and kiwifruit seed destruction. 

KVH and the Bay of Plenty Regional Council have been supportive of this research as increasing quantities of reject fruit for composting will likely reduce the amount of fruit available to birds resulting in further wild kiwifruit populations.  There is thought to be about 60,000 tonnes of reject fruit produced from Bay of Plenty post-harvest companies.

KVH has received numerous enquiries from compost suppliers in the last month.  KVH is continuing to work with Zespri’s OPC to develop a KiwiTech Bulletin providing guidance around suitable compost compositions and distribution protocols.
