Many Waikato growers reported high levels of Psa-V symptoms in spring 2015 and in some blocks, cutting out due to infection continues. Sites that experienced multiple frosts below -2 degrees through winter and/or autumn were hit particularly hard. Due to the harsh winter, Psa-V symptoms were more severe and widespread than in 2014.
KVH visited Hayward and Gold3 Waikato orchards a number of times through 2014-15 to work with growers and observe Psa-V progression and management practices.
KVH is analysing the data received for the annual mandatory monitoring round which was due on 31 October 2015. However, less than half of the required results were received by that date.
Growers are reminded it is a requirement under the NPMP to report mandatory monitoring results annually for all growers in Exclusion and Containment Regions and Not Detected orchards in Recovery regions. KVH will pass this information on to Global GAP auditors for follow-up.
A break-down of regional submissions as of 7 December 2015 are outlined in hte table. (Exclusion and Containment regions are in blue).
Last week the Ministry for Primary Industries (MPI) announced the successful eradication of the Queensland Fruit Fly from Auckland and officially closed out the response operation and lifted the restrictions on fruit and vegetable movements.
Over the last 10 months a huge amount of effort and resources has gone into the operation to assure MPI and our offshore markets that New Zealand is once again fruit-fly free.
The most affected households were located in the middle of the Controlled Area and have been extremely supportive during the response. Next week, KVH together with Pipfruit NZ and Horticulture NZ will visit the area and give a small token of thanks on behalf of NZ’s fruit and vegetable growers.
KVH recently made a submission to the Ministry for Primary Industries (MPI) on proposed changes to the ‘Post Entry Quarantine Facility Standard for Plants’.
The key changes proposed by MPI include:
The process for developing the standard has been inclusive of industries, with strong support by GERMAC (the Germplasm Advisory Committee, of which the kiwifruit industry is a member) and guided by a project board made up of MPI, industry and Crown Research Institute representatives.
KVH has supported the proposed changes overall and acknowledged MPI both for the quality of its’ proposal and industry inclusion in development of the proposal.

Yesterday KVH facilitated it’s third (and twice-annual) KiwiNet workshop with around 20 participants from across the industry. The aim of the workshop was to keep the group engaged, inform them of emerging biosecurity threats and activities undertaken to mitigate the risk and impact of these threats, and also to discuss ways to continually improve KiwiNet and its systems for any future responses (should they occur).
The group was presented with information on emerging risks to the industry (pests and diseases other than Psa and fruit flies) and new induction material that will provide kiwifruit staff with clarity of what is required of them during a response should they be called upon.
A highlight of the workshop was a presentation on the fungal pathogen Ceratocystis fimbriata by Dr Joy Tyson (Plant and Food Research) – click here.
Ceratocystis fimbriata is considered one of the most serious biosecurity threats to the kiwifruit industry and is causing extensive damage to the Brazilian kiwifruit industry.
Joy has visited Brazil and met with international experts in this field. Her presentation provided an overview of the impacts experienced in Brazil and the research being funded by the New Zealand kiwifruit industry to prepare for this threat should it ever arrive.
A key message for the industry from this presentation was if Ceratocystis fimbriata was to enter New Zealand there may be an opportunity to eradicate it if we are able to detect it an early stage. Therefore, unusual vine symptoms should always be reported. Tool hygiene and sourcing clean plant material will reduce the likelihood of spread, and should always be implemented as pathogens can be spread before we know they are here.
More info on Ceratocystis fimbriata and the research the KVH and Zespri are funding can be found here.
KVH is pleased to see that the Ministry for Primary Industries (MPI) have responded to new research on this organism and have introduced urgent amendments to the nursery stock import health standard to reduce the risk of Ceratocystis fimbriata entering on this pathway.

KVH is investigating an unauthorised movement of an orchard tractor from Tauranga to Nelson. Due to the risk of transferring Psa-V and/or other organisms between regions, machinery movements from a Recovery region to an Exclusion region are restricted and KVH permission is required before movement occurs.
KVH will inspect the machinery to ensure all plant material and soil is removed; that wash-down has occurred and a KVH approved sanitiser (e.g. Virkon at 1%) has been applied.
In this case the tractor had been sitting in a sales yard for an extended amount of time and had been cleaned before and after movement. Letters of warning have been sent to the machinery dealer and orchardist involved. If the movement had occurred between kiwifruit orchards, a prosecution under the Biosecurity Act may have resulted.
Orchardists moving orchard machinery, undertaking development or any other work involving inter-regional movements are reminded to gain the required permissions.
If you are unsure of KVH requirements refer to KVH Protocol: Orchard Equipment and Infrastructure or call KVH on 0800 665 825.
The last day for Hill Laboratory to receive samples is Friday 18 December 2015, so please ensure any samples to be tested arrive on or before that date.
Start-up date for the New Year will be Tuesday 5 January 2016.
Only KVH pre-arranged urgent testing will be accepted between these dates. Please call Karyn Lowry on 027 227 1157 if you require urgent testing between 18 December and 5 January 2016. Photos of symptoms will be required.
We anticipate these will only be samples from areas currently free of Psa (i.e. South Island).
