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.

Stink bug high-risk season starts again
6 September 2019

People are being encouraged to keep an eye out for the Brown Marmorated Stink Bug (BMSB) now that the high-risk season has begun. BMSB is not currently established in New Zealand. 

‘We are asking everyone to look out for this stinky pest as early detection is vital,’ says Dr Ed Massey, Chair of the BMSB Council. 

‘That means spreading the word so that all New Zealanders know what to look for and what to do if they see a BMSB, especially when opening overseas packages and when unpacking after an overseas holiday.’  

‘If you think you’ve seen this stink bug, catch it, snap it and report it by calling the Biosecurity New Zealand hotline on 0800 80 99 66.’ 

Although BMSB is a major concern to primary industry groups because it can destroy fruit and vegetable crops, it is also a significant public nuisance that will readily invade and infest people’s homes and outdoor spaces in large numbers, making it one of the top most unwanted pests that every New Zealander will want to keep out of our country.  

For the high-risk season, Biosecurity New Zealand has strengthened pre-shipment requirements when importing vehicles, machinery,  parts and sea containers from 33 high-risk countries.

‘The BMSB Council believes these measures will help to reduce the likelihood of BMSB crossing our borders through these higher risk pathways,’ adds Ed.  

The Council is a group of industry organisations that partner with Biosecurity New Zealand – through the Government Industry Agreement for Biosecurity Readiness and Response – to improve New Zealand’s readiness for this high priority pest.

Work is also ongoing via the Council on the Samurai Wasp,  a poppy seed-sized natural enemy of BMSB which lays its eggs into the stink bug eggs preventing them from hatching. In August 2018, the Environmental Protection Agency (EPA) granted pre-emptive approval - with controls - to release this natural enemy following a BMSB incursion.  

‘The Council has a complex programme underway to make sure a ready supply of wasps is availableand we are confident that it could be a key tool to fight these unwanted stink bugs.’ 

‘Worldwide, there are no facilities selling the wasps commercially and while several offshore labs have wasp colonies, they are primarily for research purposes. As a result, the BMSB Council is exploring options for sourcing the wasp such as rearing them offshore with the ability to ship to New Zealand or rearing them onshore under containment.’    

More information, including video and imagery is available on the KVH website and Biosecurity New Zealand website.

Most Unwanted time of year
5 September 2019

Fruit flies and Brown Marmorated Stink Bug (BMSB) are considered two of the biggest biosecurity threats to the kiwifruit industry and from September they are both in their highest-risk period for entry into New Zealand. A quick reminder of the damage these unwanted pests can do and what to look out for:

Fruit flies:

·         High likelihood of entry – have crossed our borders many times.

·         Production impacts for a range of horticultural crops but considered low for kiwifruit.

·         Severe market access restrictions, particularly for Queensland Fruit Fly, which is not present in most major kiwifruit markets.

BMSB:

·         Pierces kiwifruit resulting in fruit drop and rot. Fruit loss is typically 5-10% but up to 30% on worst blocks. Extremely difficult to eradicate – early detection is essential.

·         Major nuisance pest overwintering inside homes in huge numbers.

·         High likelihood of entry as a hitchhiker on shipping containers, cars, machinery and luggage.

For more information on these and other biosecurity threats to the kiwifruit industry, see the new Kiwifruit’s Most Unwanted list on the KVH website and contact us on 0800 665 825 if you would like one of the new posters or leaflets sent out to you.
