Symptom expression in cold orchard locations - Waikato observation report
25 September 2014

Orchard sites that experienced colder autumn and winter periods are reporting a higher incidence of Psa-V symptoms this spring.

Wanganui, Waikato, and Waihi sites, which experienced frosts shortly after harvest and also had a number of frost events with temperatures below zero for extended periods, are reporting increased levels of symptoms in Hayward males including Chieftan.

Late growth which was not fully mature, or growth that was damaged through autumn storms, is showing higher incidence of secondary symptoms.

Growers are recommended to particularly focus on colder areas of their orchard when monitoring to determine individual orchard impacts.

Future pollination supplies
25 September 2014

This week KVH held a meeting with pollen providers. Available pollen across the industry is around 50 percent lower than last year (which was not a good year for pollen). This could potentially cause problems with supply for 2014 if male vines are compromised due to Psa-V infection.

Growers are urged to have their early male flowers picked for pollen and if possible, support pollen providers by supplying flowers and labour. Contact your local pollen provider if you are able to help the industry build up supplies. Click here for a list of registered pollen providers on the KVH website.

All those intending to operate a pollen mill this season are required to register with KVH here.

Industry Operational Working Group for Fruit Fly Preparedness
25 September 2014

As advised in the KVH Bulletin (24 April), the Plant Market Access Council (PMAC) including Zespri and KVH have been working on a project which aims to pre-emptively agree market access conditions with key markets in the event of future incursions of significant fruit fly species in New Zealand.

The project includes developing protocols which demonstrate how New Zealand will manage a fruit fly incursion and how exporters will therefore be able to reliably export fruit fly free product minimising any trade disruptions.

For trading partners to agree to these protocols, which if a breeding population of fruit fly is found would be based on cold disinfestation of fruit, the industry must be able to demonstrate their own procedures for implementing any agreed protocols.

Therefore, ISG has recently agreed to establish a small industry working group to identify and address associated operational issues.

The objectives for this working group will be to:

  • Identify the key issues and the range of possible scenarios that need to be considered and planned for depending on what the nature of the fruit fly outbreak is, and what time of year it happens in.
  • Develop a set of guidelines to assist individual post-harvest operators to develop their own documented quality management plan for approval by MPI should cold disinfestation of fruit be required by our markets.
  • Discuss the guidelines with MPI for comment and agreement prior to publishing these to the wider industry.

It is essential for our industry to plan for what would need to be implemented, often at very short notice, in order to minimise market disruptions.

It’s important to note that while MPI are beginning the negotiations, it will likely take years for some countries to agree to these protocols.

Canker management
18 September 2014

KVH has recently received a number of reports of red exudate appearing, particularly in male vines. Best practice advice is to determine the level of infection in each block by monitoring and recording the number of plants infected and the severity of infection.

If cankers are isolated, such as at the ends of canes or leaders, consider removing them. For cankers that cannot be easily removed, excision or cauterisation may be an option. Note—research has shown cauterisation is less successful at slowing canker spread than total removal.

Growers with more susceptible male varieties should consider their options now to graft some, or all, of their male vines over to another variety in the upcoming November grafting window. It is also important to consider the potential impact on pollination, and plan now to ensure artificial pollen can be procured. Above all else, it is important to have a plan in place to determine how cankers will be managed, and the process that will be followed moving forward.

Proactive early spray programmes key to Psa-V control
18 September 2014

A focus on spraying at regular intervals from budbreak onwards will provide ongoing protection of expanding leaves and shoots. Leaves in the first week of emergence and up to three weeks old are most vulnerable to Psa-V infection.

‘Pulses’ of leaf infection observed in previous years may have been due to high numbers of leaves at this vulnerable stage not being suitably protected through significant infection events. 

Psa-V inoculum on the edges of leaf spots can reactivate in suitable weather conditions and add to the inoculum load within the canopy. This increases the risk of flower bud infection across the spring period. Hayward and Green14 can be particularly vulnerable to this infection.

A full winter rate copper with a spreader applied immediately prior to budburst is highly recommended to protect breaking buds on all varieties.
A following regular programme of coppers, Actigard™ and, in high-risk situations, KeyStrepto™, should be applied through to flowering.

Ambitious may also help reduce leaf spot and may be applied once there is sufficient leaf in the canopy (see photo). Similarly, Actigard™ also requires sufficient leaf cover at time of application to ensure uptake is sufficient to fully activate the vine. Manufacturer recommendation is to apply Actigard™ two to three weeks after bud burst, when leaf diameter is approximately 25mm.

Many Hort16A canopies will already have sufficient leaf for application of these products. AI nozzles and drift-reducing adjuvants must be used until canopy closure to minimise spray drift.  Excellent spray coverage will optimise product efficiency. Use of wetter papers is recommended to check applications.

Plant Health Australia visits Te Puke
18 September 2014

Plant Health Australia (PHA), the industry body that coordinates the government-industry partnership for plant biosecurity in Australia, visited KVH yesterday to learn about our Psa-V management approach, and to share information about future biosecurity priorities.

The full Board of Directors participated in the visit and were extremely impressed with what the NZ kiwifruit industry has accomplished in just under four years since Psa-V arrived, in terms of managing and reducing the risks using the NPMP, and also the major R&D efforts that have been achieved.

Discussions on future biosecurity priorities included understanding the Australian approach to cost sharing for fruit fly, where the arrangement in place has government funding 80 percent and industry 20 percent of the costs associated with responses.

Trichoderma product available
18 September 2014

As advised in the KVH Bulletin (15 May) Lincoln University is manufacturing a prototype trichoderma product called Trimix 1. Trichoderma are fungi present in soils, and some strains are able to colonise the root system of plants resulting in beneficial effects to the plant.

Trimix 1 is available once again to growers for use as a plant health enhancer (bio-fertiliser) from Lincoln University.They also recently received BioGro approval for TriMix-1 so it can now be used without restriction by organic growers.

While there is experimental evidence that the TriMix 1 can improve plant growth, Lincoln and/or KVH and Zespri cannot promote the product for Psa-V control as it does not have ACVM label claim from the Ministry for Primary Industries (MPI).

Growers interested in using the product as a plant health enhancer (bio-fertiliser) can click here to email Lincoln University.

Coromandel update
18 September 2014

A KVH meeting in Coromandel on Tuesday was well-attended by local growers. Psa-V expression in the region has increased significantly over the last month.

The region has experienced a cooler and wetter winter than previous years which is seen as a major contributor to the increased levels of Psa-V.
Some orchards that suffered frost shortly after harvest did not have an opportunity to apply an autumn Actigard™. These orchards are showing considerably more Psa-V than those in the same area who did manage to apply Actigard™. 

A number of Hort16A orchards showing increased symptoms are being actively monitored with regular cut-out to remove Psa-V and growers have applied KeyStrepto™.  All but one remaining Hort16A orchard are now notch-grafted and growers are looking to remove susceptible male vines following flowering.

Hayward and Green14 in the region are showing few symptoms at this early stage. The Gold3 grafted in 2012 is generally looking good. However, 2013-grafted Gold3 is showing increasing symptoms with a number of orchards cutting out infected areas.

While in the region KVH also visited a Psa-V positive Hort16A Coromandel orchard.
