Your new seasonal management guide
19 September 2019

A reminder the Psa Seasonal Management Wall Chart for the 2019-20 season is out now (you should have received an A2 poster copy in your August Zespri Kiwiflier).

You can view and download the chart from the KVH website or contact us if you’d like extra posters sent to you.

A key feature is the KVH Recommended Product List, which sets out the upcoming seasons approved products for protection against Psa, their year-round application rates and permitted use periods. The biggest changes to this season’s wall chart are:
 

·         The addition of a Bio-bactericides section, listing details for the use of Actigard.

·         The removal of Caplit from the CPPU section.

·         More emphasis on cultural management of Psa, including information about sanitising tools and pruning.

Stink bug round up
19 September 2019

Earlier this week the Newsroom news site published an article and podcast on Brown Marmorated Stink Bugs (BMSB), the havoc they’re wreaking overseas, and the nationwide efforts underway here to keep this unwanted and damaging pest out.

The entertaining podcast tells the history of stink bugs in Asia, the USA and Europe from a grower perspective, explains why we have a high-risk season, and includes great interviews with Cath Duthie from Biosecurity New Zealand (who has seen BMSB first-hand through her extensive visits to Europe and in particularly Georgia), David Vinsen from the Vehicle Importers Association and Ed Massey from NZ Wine who is Chair of the BMSB Council - the joint industry group working together to raise awareness about the impacts of BMSB and managing all the ‘cool stuff’ being researched to keep it out.

BioGro lowers copper input limits for organic production
19 September 2019

BioGro has confirmed that from last Wednesday 11 September 2019, the limit on the use of copper-based inputs for organic production has been lowered to 3kg active copper/ha/year.

This applies to all BioGro Licensees and flags the end of an interim exemption which allowed a temporary increase to 6kg/ha/year to support growers in the control of Psa following the disease’s outbreak.

BioGro certified products with ACVM registration for Psa affected by this change include Nordox 75WG, AG Copp 75, Champion++, and Hortcare Copper Hydroxide 300.

BioGro Licensees should contact the BioGro office with any queries or concerns regarding this change.

No fear of reporting suspect finds
19 September 2019

The sooner you alert us to anything unusual, the more we can do to help. Early detection is key to eradication – if we don’t report and miss this window, any one of a number of unwanted pests could establish and be a challenge we have to deal with forever.

We understand that reporting a potential biosecurity threat can create anxiety for some growers, who may worry about potential implications or movement controls that may result. 

KVH has developed Kiwifruit’s Most Unwanted information and fact sheets, which are available on the KVH website. While these organisms are considered the greatest potential threats to the kiwifruit industry, the next incursion we face could be another damaging pest or disease not yet on our radar. Look out for plants displaying any unusual symptoms and pests not commonly seen.

Travelling overseas these school holidays?
19 September 2019

Kiwifruit growers travelling during the school break (starting next Friday 27 September) may find they experience more interventions when returning to New Zealand. This is because Biosecurity New Zealand border staff consider occupation as part of their risk assessment, and growers could potentially pose a greater biosecurity risk based on the likelihood they may have visited offshore orchards and farms during their travels.

Kiwifruit growers returning to New Zealand should:

·         Before packing, clean all risk items (e.g. shoes and equipment) that may have come into contact with any soil or plant material. Ideally use a sanitiser.

·         Declare any visits to an orchard or farm while overseas.

·         Declare or dispose of any risk goods on entry (e.g. food items).

·         Answer all questions honestly, even if it means a short delay getting through border clearance.

KVH has put together a useful poster outlining everything growers can do to help reduce biosecurity risk and what they can expect through border control when returning home.

Psa monitoring window
19 September 2019

Budbreak is well underway for most Gold3 sites and it is recommended growers complete Psa monitoring rounds to check for early signs of the diseases.

Reports from Gisborne, Edgecumbe and Opotiki regions confirm exudate is now showing in Psa cankers and some girdles for sites where Psa has been more prevalent. A few new hot spots have also been seen, often where spray programmes or hygiene have been compromised.

The Psa Risk Model currently shows fine weather through to Tuesday next week for most regions, with a four-to-five-day period of moderate risk following. Advice is to complete monitoring and ensure copper protection of new growth before this risk period.

A review of the number of days with moderate or severe Psa risk reported through winter and early spring (across the weather station network) can give growers some clues as to which regions may have more Psa pressure this year.

Whangarei has the highest number of risk days (65 days), followed by Waikato (55 days), Te Puna, Katikati, Kerikeri and Waihi (43-50 days). Nelson, Edgecumbe, Opotiki and Te Puke have between 34-39 days, while Gisborne and the Hawkes Bay had drier winters reporting around 25 days of moderate or severe Psa risk through the period.

Mandatory monitoring underway
19 September 2019

All growers in Exclusion regions and all growers with ‘Not Detected’ orchards in all regions are required to carry out a round of Psa mandatory monitoring from mid-September with results due to KVH by Thursday 31 October. To assist growers, an online monitoring form is available here.

Please call KVH on 0800 665 825 if you have any questions or require assistance to complete the form. If Psa-like symptoms are found for the first time on an orchard, report these to KVH. Growers can also contact their pack-house technical representative for advice and sample collection if required.
