Mystery Creek Fieldays
12 June 2014

Hundreds of growers and people attending this year’s Mystery Creek Fieldays have visited the Zespri tent over the last two days to sample fruit and hear from Zespri, KVH and NZKGI representatives during the daily lunchtime presentations.

KVH operational and biosecurity staff are available on site with information about KVH and its Psa-V and biosecurity roles.

Feedback from growers has been very positive, with many growers keen to share their knowledge and experience on how they are protecting their orchards.

For those planning on attending the Fieldays, KVH will be onsite again tomorrow (Friday) and Chief Executive Barry O’Neil will be giving a short update during the lunchtime presentations.

Severe weather event - protect your vines from Psa-V now
12 June 2014

Due to the severe storm being experienced around the country, growers should be protecting their vines by applying a protective copper spray as soon as possible following the rain. Storm damage, including multiple leaf scars from leaves being stripped from vines, create Psa-V entry points.

Copper applications have shown to be the most effective control of Psa-V during the post-harvest and dormancy periods.

Follow label instructions and use winter rates.

Growers with high-risk blocks, including those showing Psa-V infection and young vines, may also consider antibacterial products.

Kiwifruit Plant Certification Scheme
12 June 2014

As advised in the KVH Bulletin (29 May) nurseries can now certify their kiwifruit plants to the Core Standard under the Kiwifruit Plant Certification Scheme (KPCS).

This means growers will soon be able to purchase certified kiwifruit plants from participating nurseries, giving them assurance they are investing in the best possible start when establishing new vines.

Border Interventions on Import Pathways - Profile No. 2 International mail
12 June 2014

The second border pathway to feature the KVH profile series is International Mail. Each year 40 to 50 million mail items are processed at New Zealand’s International Mail Centre, located near Auckland Airport. MPI’s biosecurity team use risk profiling, x-rays and detector dogs to screen and process incoming mail on this pathway and seize around 40,000 biosecurity risk items annually.

Mail is considered a low risk pathway for the entry of fruit fly host items; and in the past 12 months only one fruit fly host item has been intercepted on this pathway. However, as a precautionary measure in response to this year’s Queensland Fruit Fly finds in Whangarei, MPI have increased detector dog presence to 100 percent coverage for all high risk mail items.

Potted Plant Field Trial Report - Elicitors on Gold3 Potted Plants
12 June 2014

Using Gold3 potted plants, this trial was to determine the efficacy of a range of elicitors and forchlorfenuron products in inducing a plant immune response to Psa-V.

All the elicitors, except Alexin, significantly reduced leaf spot in Gold3 group up to 37 days post Psa-V inoculation (p < 0.05). None of the elicitors significantly reduced secondary symptoms. Actigard™, which was used as a positive control, had the greatest effect in reducing leaf spotting and secondary symptoms compared with the Psa-V group.

Testing the products in this trial on other kiwifruit varieties may result in a different response to ones observed in this trial, as an elicitor response may be kiwifruit variety-specific.

ACVM approves limited-label claim for KeyStrepto
12 June 2014

The Agricultural Compounds and Veterinary Medicines (ACVM) group within the Ministry for Primary Industries has approved a limited-label claim for KeyStrepto™ for use as a Psa-V protectant on producing and non-producing kiwifruit vines.

  • Between 13 June and 31 July 2014, KeyStrepto™ use is permitted with a Justified Approval (JA).
  • A JA is not required from 31 July 2014 until seven days before the first kiwifruit flowers opening (male or female).
  • KeyStrepto™ must not be used during flowering.
  • Post-flowering until 28 February 2015 – KeyStrepto use is permitted on non-producing vines only and a JA is required.

The conditions of use for KeyStrepto™ include:

  • KeyStrepto™ is permitted for use in the North Island only.
  • Must be applied at the label rate. For concentrate spraying adjust rates accordingly.
  • AI nozzles must be used until the canopy develops. Apply with a suitable adjuvant.
  • A maximum of four applications of KeyStrepto may be made per season.
  • No more than six antibiotic applications (Kasumin® and KeyStrepto) in total per season can be made.
  • Do not apply more than two consecutive sprays of KeyStrepto™ before applying a different Psa-V control product.

Growers must refer to the KeyStrepto™ User Guide for detailed rules of use, including sward management, notification, signage, record keeping etc.

Zespri will once again test 100 percent of supplying orchards for more than 300 residues – including antibiotics – in the 2015 season.

Antibiotic label claim
5 June 2014

KVH continues to work with Zespri and ACVM to confirm label claims and use conditions for KeyStrepto™ and Kasumin® post 15 June 2014. Currently both products cannot be used before 15 June unless a Justified Approval (JA) is issued by Zespri, and only under extenuating circumstances.

Unless we receive confirmation from ACVM as to the use condition, this date is likely to be extended.

KVH will advise growers of progress through the KVH Bulletin.

Psa-V identified in Japan
5 June 2014

Psa-V infection has been confirmed in Japan.

The disease was first found last month in the Ehime Prefecture, Japan’s largest kiwifruit production area; and soon after was confirmed in the Southern area of the Fukuoka Prefectural.

Growers in both regions have cut out all infected vines.

The Prefectural Governments together with agricultural officials and advisors are investigating the extent of the spread; and advising growers of best-practice control measures including monitoring for early detection, cutting out infected material and tool sterilisation.

Emergency financial assistance has been offered to kiwifruit growers’ for disease prevention measures.

Coromandel - regional update
5 June 2014

Coromandel harvest is now complete and most crops have achieved close to their estimate. Growers have been actively applying copper and Actigard™ post-harvest.

Psa-V symptoms have recently increased, particularly in Hort16A and Gold9 orchards.  One of the original Psa-V Gold9 sites is described as 95 percent clear of Psa-V symptoms. This follows an aggressive copper programme.

M33 males in a Gold9 orchard are expressing cane and shoot dieback. However M91 males in the same block appear to be clear of symptoms.

Growers are reporting Gold3 as clear of symptoms, except for those that were grafted onto heavily infected rootstock.

Conversion of Hort16A orchards will continue this winter. Some Hort16A growers whose orchards are not showing symptoms will continue for a 2015 crop.

Imported pollen warning
5 June 2014

A Coromandel kiwifruit grower recently received an email from California-based company Pollen Technologies, offering to supply kiwifruit pollen for artificial pollination.  It appears the pollen is sourced from either the United States or China with samples available upon request.

KVH immediately alerted MPI Imports and Exports Group (plants) of the email and contacted the Californian company to inform them that: importation of any pollen into New Zealand for plant breeding purposes is currently prohibited; the company should not solicit enquires from New Zealand; and to immediately stop all promotion of their pollen products and services in New Zealand. 

KVH included information regarding the National Psa-V Risk Management Plan’s rules and risk management around artificial pollination within New Zealand. 

MPI also contacted the supplier to confirm pollen imports are strictly prohibited. 

The company has confirmed it has not sent pollen to New Zealand and it will abide with KVH requests and not seek orders or offer samples of pollen to New Zealand kiwifruit growers.

If any growers receive any further offers of pollen or samples of pollen from a Californian, Chinese, or any overseas based company, then please alert KVH and MPI immediately.  The MPI contact should be made through the MPI exotic pest and disease hotline: 0800 80 99 66.

This now allows the movement of budwood from Psa-V positive orchards to other Psa-V positive orchards for all Recovery regions subject to meeting requirements of the Protocol. These changes apply to all kiwifruit varietal budwood. Plant variety movement approval will still be required from variety owners.
