Chile update
11 June 2015

Harvest is underway in Chile with many growers still seeing lower volumes as they recover from the devastating spring frosts in September 2013. This frost resulted in around 60 percent reduction in Chilean export in 2014.

On Psa-V affected orchards, growers are seeing high levels of canker and dieback in Hayward. Hayward comprises more than 95 percent of kiwifruit plantings in Chile.

Psa-V is established in the Biobio, Maule and O’Higgins regions and appears to be progressing north. Psa-V has recently been confirmed in Chimarongo, which is around 25 kilometres north of the last mapped point.

SAG (Servicio Agricola Y Ganadero – the equivalent to NZ’s Ministry for Primary Industries) release their annual Psa statistics at the end of each year. 

The Chilean Kiwifruit Committee met recently to review their recommendations to Chilean growers for Psa-V disease control and now include recommendations for products and rates for disease control. The recommended copper rates are higher than in New Zealand. The Committee intends to carry out research to determine minimum effective dosage under local conditions.

In Chile kiwifruit is typically one of a number of crops on a property. Other crops might include apples, table grapes, nectarines, cherries, walnuts, hazelnuts, plums and almonds. Soils are often heavy and a reasonable number of kiwifruit plantings are on raised ridges.

Biosecurity No.1 concern amongst agribusiness industry leaders
11 June 2015

KPMG have just released the 2015 Agribusiness Agenda and a world-class biosecurity system has been rated the number one priority by agribusiness industry leaders for the third consecutive year.

Scores indicate that biosecurity is even more important now than in 2014.  The report states increasing global connectivity makes it critical to continuously reassess the most robust, cost effective biosecurity solutions for New Zealand; and the Biosecurity 2025 strategy review is a prime opportunity to bring some fresh collaborative thinking to biosecurity.

Over the coming weeks the first Biosecurity 2025 working group sessions will take place with KVH participating to ensure that the interests of our industry are included in the strategy.

New R&D report - quality testing of compost samples
11 June 2015

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 compost tested 'not detected' for Psa-V and kiwifruit seed was destroyed during the composting process.

Winter rates of copper
28 May 2015

Growers should now be moving to winter rates of copper. Copper use reduces through summer and coverage needs to be rebuilt as the risk of frost and hail increases and wetter conditions prevail.  Leaf spotting from spring infection still provides inoculum sources and heavy morning dews can provide sufficient moisture to re-activate Psa. 

Growers beginning winter work on Gold3 are noting some dehydrated cane and cane die-back in their canopies; and some Hayward growers in the Katikati region have also commented they are seeing new spotting on Hayward leaves. This indicates recent Psa infection and reminds us that Psa has not disappeared.

Frost damage, leaf-fall, wounds created when dropping strung canes and pruning activities all create opportunity for Psa to enter. Therefore levels of inoculum in the canopy must be managed.

After harvest, a copper and Actigard™ mix is recommended if leaf condition remains strong (leaves must be actively photosynthesizing to maximise the value of Actigard™). Do not apply Actigard™ to stressed vines.  Further applications of copper will be needed through the leaf-fall period and before and after winter pruning. Protection through dormancy presents much lower risk of phytotoxic effects.

Also, check the coverage of sprays applied.  Slow down to maximise the value of the applied products and avoid product waste through run-off.  Addition of spreaders will improve coverage and penetration into cracks and crevices. Time on target is important, and alternating the direction of travel for consecutive spray passes will help compensate for shadowing from pergola structures.

MPI cost recovery for food safety and biosecurity
28 May 2015

MPI have completed a review of how costs are recovered from individuals and industries for food safety and biosecurity services and have updated a number of fees that will come into effect on 1 July 2015.

KVH has been involved in the consultation process of the Cost Recovery Review and supports a user-pays approach and changes to regulations and operating procedures that result in better biosecurity protection for our industry.

The user-pays approach is consistent with the new passenger surcharge at the border announced in the last week’s budget.

Details on the fee changes for biosecurity services are available on the MPI website.

Frost protection
28 May 2015

Immature growth and leaves must remain protected through the autumn period with copper applications, particularly in frost-prone areas.

Many growers choose not to use frost protection as leaf-fall allows pruning to get underway. However, with frost comes the added risk of Psa movement into leaf and cane tissue. 

Inoculum levels within the orchard must be minimised to avoid disease spread. Growers with frost protection, particularly those with windmills, should consider protecting high-risk blocks such as developing Gold3 canopies and young plants. Psa multiplication is rapid in frosted tissue and the colder the frost, the higher the risk.

Italian research also showed water-soaked leaves damaged by frost developed Psa in 100% of cases when sprayed with Psa inoculum vs 20% infection for non-frosted leaves.

Once plants harden off in winter this risks reduces. Males are likely to be vulnerable later into the season as they are often slower to lose their leaves.

Kiwifruit Plant Certification Scheme moves to single Standard
28 May 2015

It has been a year since the Kiwifruit Plant Certification Scheme (KPCS) was introduced through the launch of the ‘Core’ Standard.

During this time the Scheme has gained momentum with nurseries and growers. To date, four nurseries have met the Standard and are now selling certified plants; and KVH is working with other nurseries who intend to meet the requirements of the Standard and join the scheme.

Over the last year KVH has consulted with nurseries and growers, and hosted two KPCS workshops with members of the nursery, grower and science communities.

Engagement with the industry has been an important part of the development process and this feedback is now being incorporated to better improve the KPCS for nurseries and growers.

Yesterday an update was sent to all kiwifruit nurseries outlining the current status and future direction of the Scheme, and this included the move to one Standard only (initially a more rigorous, High-Health Standard was planned for development). The single standard will be no longer be referred to as the ‘Core’ Standard but the ‘KPCS Standard’.  This change is reflective of the feedback and suggestions received from the nursery and grower communities.

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.
