High-risk weather warning over Easter
24 March 2016

Weather warnings have been issued over the Easter weekend and the KVH Risk Model is showing high-risk weather for Psa in many regions including Te Puke, Kerikeri and Whangarei.

Heavy rain and strong winds can cause damage to vines, increasing risk of Psa-V infection and spread.

Growers with orchards impacted by this weather are recommended to apply a copper spray immediately following the weather event and monitor at-risk areas of the orchard.

Copper tolerance/resistance monitoring update
24 March 2016

Preliminary results from the latest KVH round of the ongoing Psa resistance and tolerance monitoring programme show a significant increase in the number of samples with a degree of tolerance to copper.

The February/March programme tested 237 samples from 99 KIPNs. Of these, forty-two samples showed low levels of tolerance to copper; and 23 samples showed medium levels of tolerance to copper. These samples were from 56 KPINs. The level of tolerance identified is still below the concentration of copper in a spray tank when applied at recommended rates, but the development is concerning.

The orchards are spread across the growing regions with the majority of orchards identified in Te Puke. The other areas are Whakatane, Opotiki, Poverty Bay, Coromandel, and Kerikeri.

KVH is contacting the owners of the orchards showing medium levels of copper tolerance to review what is happening on orchard and attempt to better understand the potential implications on Psa control. Orchards where copper tolerance has been identified are also required to manage risk items off-orchard to reduce the risk of transferring the bacteria to other locations.

All growers are encouraged to ensure copper is applied at label rates using high enough water rates to ensure complete coverage of the canopy and to follow best practice Psa management advice. This includes a comprehensive spray programme of five copper applications at full winter rates, starting immediately post-harvest and through dormancy. It’s also important to remove infected material from orchards, maintain good hygiene between vines and alternate spray protection products.

In addition to the resistance and tolerance monitoring work being carried out for KVH by Hills Laboratory, Otago University, Massey University and Plant and Food Research are undertaking studies looking at the genome sequence of Psa and how the bacteria is evolving on orchards. All these researchers have identified the presence of additional genes that they believe are associated with copper resistance in Psa. These samples were from a selection of orchards in the Te Puke region. It is important to note these research institutes have each used a different testing methodology to determine the level of copper required to inhibit the bacterial growth and as such, we still don’t know if this development is a significant finding.

KVH will host a collaborative science workshop in May for scientists from Otago University, Massey University, Plant and Food Research and other experts to discuss the findings to date and gain a better understanding of the situation. The objectives include agreeing a standardised testing methodology for resistance/tolerance and steps on how we best manage the increasing risk of Psa evolving and developing a resistance to copper.

Orchards that have been found to have a copper/streptomycin tolerance or resistance should refer to KVH Protocol: Resistance/tolerance to Psa control products.

Any growers concerned they may not be achieving the expected levels of Psa control from copper applications at label rates should contact KVH on 0800 665 825 or email info@kvh.org.nz.

North West Auckland region
24 March 2016

This week KVH met with North West Auckland growers to discuss autumn Psa-V protection and to reinforce the importance of orchard biosecurity and hygiene through the harvest and winter period.

North West Auckland now has ‘containment’ regional status with three of their 23 KPINs confirmed Psa-V positive.

Infected material was removed from the two Psa-V positive Gold3 blocks through to early December. However, no new symptoms have been seen in recent weeks.

Hayward vines reported Psa-V positive during the November KVH monitoring round, have found no further symptoms since cut-out of the two original symptomatic vines.

Overall growers in the North-West Auckland region have done an excellent job with biosecurity and managing the positive orchards to reduce disease spread.

Abandoned orchard removed in North West Auckland
24 March 2016

KVH has facilitated the removal of a one hectare abandoned kiwifruit orchard in the North-West Auckland region. The orchard was recorded as unmanaged three years ago but was subsequently pruned and sprayed to meet KVH requirements.

The property was recently sold and after considering all options, the new owners agreed to removal over management. The orchard was low-lying and a marginal economic proposition for continued Hayward production. Local postharvest companies were no longer interested in any possible lease.

A North-Auckland based contractor has completed the removal. Piled vines will be burnt once they have dried out and fruit picking is completed on neighbouring orchards.

KVH would like to thank the land owner and all involved in achieving a successful outcome.

If growers know of any unmanaged or abandoned kiwifruit orchards, please alert KVH with location and orchard status details – email info@kvh.org.nz.

Harvest hygiene important to reduce risk of spreading Psa resistance/tolerance to control products
10 March 2016

Research clearly shows that as we move into autumn and temperatures drop and rainfall increases, Psa-V inoculum levels start to rise.

With the upcoming harvest we will also see a big increase in movement of people and machinery between orchards.

Growers and contractors are reminded to make sure good orchard hygiene practices are in place; not just to reduce the risk of spreading Psa-V through machinery, tools, people and vehicles, but also to reduce the risk of spreading streptomycin-resistant and copper-tolerant/resistant Psa-V that may be present but undetected.

As previously reported, streptomycin resistance and copper tolerance has been found on a small number of orchards but may well be present on other orchards.  Where it has been identified, orchards are being managed to ensure best practice is being carried out. This includes heightened hygiene measures, particularly during harvest, to reduce the spread to other orchards.

Best practice hygiene

  • Ensure all harvest equipment entering your orchard including picking bags has been cleaned and santitised before entering your orchard and it is cleaned again before moving off the orchard.
  • Minimise plant material entering bins during picking.
  • Remove plant material before bins are sent to packhouse.
  • Provide clean down areas with suitable sanitisers for machinery wash down and ensure plant material is not moved off orchard.

Wanganui - regional update
10 March 2016

KVH staff visited orchards in the Wanganui region this week to review recovery from the spring floods and severe Psa-V following a very wet and cold spring.

It is testament to the determination and strength of the growers that following their hard work in removing silt, two of the flooded orchards visited have successfully set a crop on large parts of the orchards.

Some plant deaths have occurred in the areas that suffered water logging for extended periods.  Psa-V spotting has been more severe, largely due to an inability to access the orchards with sprayers. However, both orchards were able to successfully pollinate large areas. The hot, dry summer in the region has ensured the remaining silt has dried out and the Psa-V presence has reduced. One of the flooded orchards is being removed and a second flooded orchard that has been largely abandoned is likely to be removed.

Severe Psa-V that was evident in males in some Hayward orchards in spring has impacted on pollination. While this was partly offset with artificial pollination, there has still been the need to remove volumes of poorly-pollinated fruit. One additional Hayward orchard was identified with Psa-V in spring. However, the impact has been minimal to date with a good crop set and only mild leaf spotting.

A Gold3 orchard with established Psa-V in one block, has seen the need for ongoing removal of around 5-7 % canopy. Other Gold3 blocks in the same orchard remain relatively clear. A first year fruiting canopy under a plastic cover in the same orchard is showing no signs of Psa-V and is carrying an excellent first year crop after achieving full canopy.

The KVH team presented autumn Psa-V messages at a grower meeting reminding growers that a more proactive Psa-V management programme in autumn can lead to reduced symptoms in spring.

Tighter biosecurity on Australian passengers following fruit fly threat
10 March 2016

The Ministry for Primary Industries (MPI) has tightened biosecurity screening on incoming passengers from Australia due to a recent outbreak of Mediterranean fruit fly in Adelaide.

Arriving passengers may be greeted by detector dogs as soon as they step off the plane under the strict new measures.

The use of dogs at the arrival gate allows greater scrutiny of hand luggage – the most likely source of fruit and other risk items that could harbour fruit fly. In the past, passengers would not have come across a biosecurity detector dog until they had passed through customs.

A quarantine zone has been imposed in Adelaide following the discovery of the Med-fly in locally-grown peaches.

BMSB - update on risk and actions to mitigate this risk
10 March 2016

In February MPI provided KVH and other GIA signatories with updated BMSB interception data. This interception data shows that the risk profile of this pest is changing.

Interceptions from the USA have decreased, which may indicate that measures introduced by MPI and their US counterparts are successfully reducing the risk of entry through this pathway. However, interceptions from Europe are increasing.

BMSB was first detected in Europe in 2007. It is now established in nine European countries and is likely in the early stages of a population explosion similar to what we have seen in the USA. This population growth and range expansion is reflected in the interception data with a clear spike in interceptions from Italy.

Actions
MPI’s readiness approach utilises a ‘BMSB network’ which includes industry organisations such as KVH. KVH’s involvement in these activities includes the following.

Response framework under GIA

  • In November last year KVH was the invited industry representative in an all of Government response exercise on BMSB to assess strategic risks associated with response options. This resulted in an agreement that eradication should be pursued.
  • KVH has participated in two formal meetings to progress cost shares under GIA should BMSB establish, and strongly argued for 100% government funding.

Research efforts to mitigate risk and impact of BMSB

  • KVH is a member of the MPI/Industry research group that overviews the R&D focus and priorities. Three priorities are developing effective traps and pheromones, ACVM approval of effective sprays and assessing biological control options.
  • KVH is also exploring further opportunities for jointly funded research. One project is underway, co-funded by Zespri to determine the impact of BMSB on “vine condition” in G3 and Hayward. This research is underway at the University of California Riverside with completion expected August 2016.

Communications to increase likelihood of early detection

  • Co-funded BMSB communications campaign with MPI and other GIA partners, to raise public awareness and increase likelihood of early detection through passive surveillance. This is the second year KVH has been involved in this campaign, the previous campaign was a success resulting in a significant increase in suspect BMSB finds, particularly in the Bay of Plenty that reported more than any other region.
  • KVH is strengthening awareness among the kiwifruit industry, associated industries such as the Port of Tauranga and the freight and logistics sector and also with members of public. This includes school visits, Mystery Creek field days, BOP Polytechnic presentations utilising our displaying specimens and handing out collateral.

Advocating for tighter measures to reduce the likelihood of entry

  • KVH put forward a submission on MPI’s proposed amendments to the Imported Health Standard (IHS) for Vehicles, Machinery and Tyres. While we supported most of the proposed amendments, KVH opposed one part that would result in removal of treatment for BMSB during the ‘lower risk’ winter period, as did Horticulture New Zealand and several other product groups. Our submission against this proposed change was on the basis that the risk over the winter period is lower but still significant (it is not ‘negligible’ as assessed by MPI), and lack of scientific evidence to support some assumptions and conclusions in the proposal (e.g., scientific evidence relating to whether BMSB entering at this time could survive and establish). The latest interception data provides further evidence BMSB is turning up on imports during winter months (May – Sept).
  • KVH has also worked with MPI in relation to interceptions of both BMSB and White Peach Scale on consignments of Italian kiwifruit, and MPI is now requiring 100% treatment of this pathway to address this risk. This is a good result and show that MPI have recognised the emerging risk from Italy and implemented appropriate measures immediately.
