Spring is a good time to review your existing Psa-V Orchard Management Plan and consider making changes to your protection strategy based on seasonal orchard observations and new research information.
The online Psa-V Orchard Management Plan template has been improved and now incorporates budwood and rootstock management sections. This avoids the need for growers supplying budwood or rootstock from their orchards to complete separate plans. The updated template is available on the KVH website by clicking here, or going to www.kvh.org.nz/orchard_management_plans.
Growers are reminded an updated Orchard Management Plan must be available with other GAP records as part of the GAP audit process. Also, the application of at least one Psa-V protectant spray from the KVH Recommended Product List is required under the National Psa-V Pest Management Plan (NPMP). All applications of agricultural compounds must be recorded in the Spray Diary.
As advised in last week’s KVH Bulletin (21 Aug) KVH has been advocating for improvements to minimise biosecurity risks on several pathways. Last week focused on the cruise ship pathway, this week will focus on transitional facilities.
Transitional facilities hold un-cleared risk goods for inspection, secure storage or treatment until they receive biosecurity clearance or are re-shipped or destroyed.
While people often think of the border as a small number of places (airports and marine ports) where clearance activities occur, the reality is very different. Most biosecurity clearance activities are occurring at transitional facilities; MPI Inspectors carry out risk profiling when imported goods first arrive at a marine port or airport, clear a small proportion of such goods at those ports (those deemed to pose the highest risk), and then direct most imported goods to transitional facilities where they receive final clearance by a non-MPI accredited person.
There are approximately 6500 such transitional facilities operating in New Zealand, which means our border is very ‘diffuse’.
The key risk is the arrival of ‘hitchhiker’ pests. These tend to be insect pests, and include high-risk organisms of concern to the kiwifruit industry such as, fruit flies, brown marmorated stink bugs and white peach scale.
KVH believes the current policy approach and standards for transitional facilities need to be re-evaluated and strengthened. There are currently too many transitional facilities operating in New Zealand and of variable quality, representing a key vulnerability in NZ’s border arrangements.
Given the level of risk and the key role transitional facilities play in New Zealand’s border, it is critical we have highly trained and skilled people operating to carry out clearance activities within transitional facilities.
KVH shared its concerns with the Ministry for Primary Industries (MPI) in early 2014, and is pleased that MPI appears to be seriously looking at this issue and potential solutions.

Growers in Exclusion and Containment regions are reminded their mandatory montioring reporting is due by 10 September 2014.
An online reporting tool is available on the KVH website. This allow growers to submit monitoring results directly to KVH. Click here to access the online reporting tool.

This season KVH has produced a visual Wall Chart to support growers with their Psa-V Orchard Management Plans for the upcoming season.
Click here for an online version of the Wall Chart.
The Wall Chart, which growers should receive in the post shortly, provides an excellent tool for raising awareness of Psa-V management and can be placed in offices and smoko rooms to support education of orchard staff and visitors.
The chart indicates the importance of a multi-layered approach to Psa-V management including:
The full Seasonal Management Guide for Spring/Summer is being finalised and will available on the KVH website next week. Any changes to the Guide, including updates to the Recommended Product List, will be made to the website version.
A new site is needed for this year’s product testing on potted plants. Ideally, this site would be close to Te Puke and isolated from high-density orchard plantings.
Four to five trials planned for the upcoming growing season.

As we move closer to spring, KVH is beginning to receive reports of Hort16A showing signs of exudate.
This week, monitoring on an isolated Hort16A block in the Katikati region showed 60 percent of the vines had fresh red exudate; and 24 percent of these vines had more than three points of exudate.
Similarly, a significant increase in symptoms were seen on an Opotiki Hort16A orchard being cut over to Gold3.
To date, Hawkes Bay and Gisborne have not reported any new symptoms on Hort16A. Regions where sap flow is a little later, i.e. Kerikeri, are reporting minimal symptoms on Hort16A and other susceptible varieties.
KVH has also received reports of increasing symptoms in Hayward vines in the Katikati/Waihi and Wanganui region. Most of these are in male vines, including Chieftan and Matua males.
Growers with more susceptible varieties like Hort16A are advised to closely monitor their vines on a regular basis to ensure symptoms are found early and action can be taken quickly.
The Zespri OPC and Innovation teams are looking for potential orchard sites for 2014-15 bud-rot prevention trials. Orchard criteria requested are:
A range of treatments are planned including different pre-flower girdling timings and spray programmes.

This week, a paper was presented to the KVH Board that uses a risk matrix to identify the high priority threats to the kiwifruit industry.
On the KVH website there are almost fifty pests and pathogens identified as potential threats to the kiwifruit industry. KVH has developed a risk matrix to provide a structured and objective method of prioritising these organisms into a shorter list for the purpose of readiness and response planning.
The report is a draft and we will be requesting subject experts to review the methodology and results of this report. However, we encourage growers to read the material and engage with KVH their views on this subject.
It is important to also remember the next incursion may not be the organism we have prepared for. Therefore, it is important to maintain a diversity of organisms in the focus group if possible and this is reflected in the report where organisms have finished with equal risk ratings.
The top five threats identified in the report are:

Following a review of biosecurity risks associated with Port of Tauranga and Rotorua Airport last year, KVH identified initial concerns with incoming cruise ships and raised these with the Ministry for Primary Industries (MPI).
KVH has been advocating for improvements that further minimise biosecurity risks through the cruise ship pathway. These include:
KVH acknowledges that some key improvements have been made by MPI over the last 12 months to tighten biosecuirty through this pathway.
MPI are now using dogs for all first port of arrivals and many second ports of arrival. Detector dogs have been used on 150 cruise ship visits resulting in the interception of 500 biosecurity risk items, of which 76 percent were fresh produce.
The cruise ship industry has more than doubled in size over the last five years (Cruise New Zealand). These cruise ships enter New Zealand waters from Australia or the Pacific Islands, regions harbouring high-risk pests and diseases including fruit flies, which are the greatest biosecurity threat to New Zealand’s horticultural industries.
KVH will continue to proactively strive for even better border intervention to reduce risk to the kiwifruit industry.

Kocide® Opti™ now has a full-label claim for the control of Psa. This was approved by the ACVM group of the Ministry for Primary Industries (MPI) on 31 July 2014. Kocide® Opti™ is a copper hydroxide product which may be applied throughout the year within a Psa-V management programme. It should not be applied to open flowers. The recommended application rate for dilute spraying is 70–90gms/100L.
HORTCARE® Copper Hydroxide 300 also received a new registration from ACVM on 1 August 2014 with a limited label claim granted for the control of Psa-V. When dilute spraying the recommended application rate for this product is 50-90gms/100L through the budbreak to harvest period; and 70–90gms/100L through the post-harvest and dormancy periods. Again, avoid application to open flowers.
The KVH Recommended Product List has been updated to include these products and they will also be included in the 2014-2015 ZESPRI Crop Protection Standard for Psa control.
As advised in previous KVH Bulletins, KVH has been undertaking Spray Diary analysis over the last month looking at the use of Psa-V protectants throughout the country over the last growing season.
Through this analysis, a number of KPINs that have not applied any of the listed Psa-V protectant sprays to their crops have been identified. KVH will work with packhouses and the growers to identify the reason no protectants have been applied.
Mandatory monitoring should be taking place in Exclusion and Containment regions over the next two weeks, with reporting due to KVH by 10 September 2014.
Information from these rounds is important to KVH. Firstly, to confirm Exclusion regions are still clear of Psa-V symptoms; and secondly, to track progression, if any, on Psa-V positive orchards in Containment regions.
To simplify reporting for growers, KVH has an online monitoring reporting form for growers available on the website. This easy-to-use tool allows growers to submit monitoring results for each variety on their orchard. Click here to access the online reporting tool.
