More than 100 growers attended yesterday’s Psa-V spring update meeting in Te Puke.
Key messages from for the upcoming season:
Growers were also presented with a technical update on streptomycin resistance and management of bud-rot in green varieties through a 30-day pre-flowering girdle.
Key messages about pre-flowering girdling:
A video of the meeting will be available on the KVH website within the next 24 hours.
Annual mandatory monitoring for growers in Exclusion and Containment regions and also ‘Not Detected’ orchards in Recovery regions is required to be carried out between 15 September and 15 October with reporting due to KVH by 31 October 2015.
An online reporting tool is available on the KVH website, allowing growers to submit monitoring results directly to KVH. Click here to access this tool and for more information about mandatory monitoring requirements in your region.
In May 2014 a plant virus in the family Betaflexiviridae was detected in kiwifruit vines held in Post Entry Quarantine (PEQ). MPI investigated this detection and concluded that the organism presents a low to zero biosecurity risk and have classified it as non-regulated organism (meaning it is not under official control).
Testing of plant material imported from the same region in China indicated the virus was present in historically imported seed possibly going back as far as 1996.
Some plants released to Plant & Food Research (PFR) in Te Puke from the same import permit tested positive for Betaflexiviridae. However, wider testing on other PFR operations in Motueka and Kerikeri, where plants were sourced from similar origins, tested negative.
KVH and PFR have worked alongside MPI in this investigation and jointly funded a significant amount of research to better understand the organism, its distribution and means of spread.
A small number of plants known to be infected with Betaflexiviridae have been removed.
A fact sheet on Betaflexiviridae is available on the KVH website here.
Spring is a good time to review your existing Psa-V Orchard Management Plan to ensure it’s up to date with the latest Psa-V management practices you are implementing on your orchard.
An updated Orchard Management Plan must be available with other GAP records as part of the GAP audit process.
Online templates to assist growers with their Psa-V Orchard Management Plans are available on the KVH website here.
September marks the beginning of Brown Marmorated Stink Bug (BMSB) season. Between now and the end of April one of kiwifruit’s Most Unwanted pests is at high-risk of entering New Zealand and growers are urged to keep an eye out for this pest this season.
The BMSB is a hitchhiker pest and likely to enter New Zealand’s border on inanimate objects such as shipping containers, passenger luggage and express freight or courier items.
Improved public surveillance and early detection is the best chance of keeping it out and ensuring it does not establish in New Zealand.
If you suspect you have found a BMSB, catch it and call the MPI pest and disease hotline on 0800 80 99 66.
The Psa-V Seasonal Management Guide for 2015-16 is now available on the KVH website.
Growers should have also received the Wall Planner version through the post.

Matt Ryan from DMS Progrowers set up a time-lapse in spring 2014 to capture the expression of sepal browning and leaf spot in Hayward kiwifruit. The plant in the time-lapse is an untreated control vine as part of a research trial.
It is interesting to see the timing of infection in relation to rainfall as well as the severity of symptom expression in what was largely seen as a low pressure season. This visualisation is a reminder of what spring can bring.
Crop protection products available this season will be discussed at the upcoming industry meeting.

Growers are encouraged to attend the spring Psa industry meeting to keep up to date with the latest R&D, Psa orchard management and recommendations for managing product resistance.
Presenters are Barry O’Neil (KVH), Joel Vanneste (Plant & Food Research), Elaine Gould and Greg Clark (Zespri).
Key topics covered:
Tea and coffee available from 2.30pm and following the meeting
To ensure KVH statistics are accurate, growers and Psa managers of ‘not detected’ orchards in recovery regions are asked to verify their orchard Psa-V status and update KVH if this has changed.

The Psa-V Seasonal Management Guide for 2015-16 is being finalised and will be available on the KVH website next week. Growers will also receive the Wall Planner version through the post.
The Psa-V Seasonal Management Guide outlines best practice for managing Psa-V and updated product rates and use conditions for the coming season.
KVH has also developed a document: Best Practice Advice—Management to limit resistance to Psa-V control products. This Guide will be enclosed in the grower mail-out and will also be available on the KVH website from next week.
MPI has firmed up details about how they will spend new biosecurity funding under Budget 2015 and there will be a raft of new measures to make it harder for air passengers to bring risk goods into New Zealand. This includes trials to test 100% x-raying of arriving baggage, more dogs and mobile x-ray machines.
The trial of 100% x-raying will test its effectiveness in conjunction with the improved border measures, and help MPI understand the logistical challenges involved. Recent statistics on the warnings and fines issued to passengers highlighted the enduring biosecurity threat posed at the border by passengers.
Read more about MPI’s border updates here.
KVH has just completed a monitoring round of Gold3 and Hayward vines across the Bay of Plenty, including orchards from Maketu, Edgecumbe, Waihi and Opotiki.
Cane dieback and fresh exudate (often from multiple points) were obvious on many male vines and some female vines. Reports of similar symptoms have been received from Waikato and Katikati orchards.
With spring around the corner, growers are advised to carefully monitor areas of their orchards where they have had symptoms in the past.
Information on Psa-V management will be covered in the upcoming spring Psa industry meeting on Wednesday 2 September.
