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.

Yachtie's fine not enough
10 March 2016

A $3000 fine imposed on an Australian yachtie who intentionally brought fruit, vegetables and meat into New Zealand is not enough to act as a deterrent: this is the opinion of Horticulture NZ and one KVH supports.

Australian woman, Dianne Young, hid the food in her vessel instead of declaring it to a quarantine officer at Opua in the Bay of Islands in 2014.

An MPI quarantine officer searching the vessel after its arrival from Fiji found eggs, oranges, apples, tomatoes, pumpkin, pineapple, onions, kumara, ginger, garlic, spring onions, meat patties, ham, eggplant, bok choy, cabbage, cucumber, capsicum and lettuce.

All these items are considered ‘risk goods’ and could harbour pests such as fruit flies – putting New Zealand’s primary industries at enormous risk.

While this discovery and seizure of fruit demonstrates MPI’s biosecurity system is robust and working well, KVH agrees the subsequent punishment by the courts should be more severe to send a much stronger message to those who intentionally break the rules.

Observations of Giant Willow Aphid on kiwifruit - understanding spread and effects
25 February 2016

New Zealand is now into the third season with Giant Willow Aphid (GWA) and the New Zealand Poplar and Willow Research Trust have field experiments in place to help evaluate the effect of GWA in New Zealand.

GWA colonises both tree and non-tree willows (shrub and osier) with the rate of colony growth differing between willow species.

Any information on which willow(s) are affected, age of affected trees, potential stressors on the affected willows and impacts such as reduced growth or yellowing or dropping leaves, helps add to the understanding of the impacts of this pest across the country.

Reporting of any situations where insecticide spraying has improved willow health is also useful.

Populations are now on the rise with a few cases of GWA recently reported from kiwifruit orchards in the Nelson region.

Growers are asked to look out for GWA and contact Sylvia Warren at Zespri if they are seeing this pest in their orchards – email sylvia.warren@zespri.com.

Regional update - Hawkes Bay and Gisborne
25 February 2016

KVH staff recently visited Gisborne and Hawkes Bay orchards that were confirmed Psa-V positive for the first time through spring 2015. 

Since 1 August 2015 an additional 14 orchards from Gisborne and five from Hawkes Bay have tested Psa-V positive.

Blocks showing symptoms last year were also revisited to understand the challenges growers had faced over the past six months.

Cold, wet spring conditions and in particular, damaging southerly winds, were considered the most likely drivers of new infections within the regions.

Growers converting from Hort16A to Gold3 with colder sites or more severely infected stumps, experienced difficulty achieving high winter graft success (pictured above). Re-grafting continued through summer and multiple grafts to the same stump and/or suckers have been completed.

Poor synchronisation of male and female flowers in some Gold3 blocks have been a concern, particularly for Gisborne growers. The need to stock pollen for artificial pollination and the importance of good male management was discussed. Male grafts on Bounty rootstock, autumn trunk-girdling of males to bring flowering forward and male management to provide a range of cane types to spread flowering timing, were all strategies thought worthy of trialling.

Two growers with young Gold3 blocks that suffered up to 20% canopy cut-out due to Psa-V through spring, identified the need to take care when managing strung cane through the autumn period. Both growers believed cane damage, and possibly poor tool hygiene during autumn work led to spring infection.  

It was pleasing to see the level of proactive management in place and the high standard of hygiene being enforced by growers in general.

The KVH team also presented autumn Psa-V messages at the Zespri OPC field days, and reminded growers that a more proactive Psa-V management programme in autumn can lead to reduced symptoms in spring.

Field assay systems for Psa trialled
25 February 2016

KVH staff recently attended a workshop, hosted by Honour McCann (Massey University) and Plant & Food Research to observe the development of a new rapid test for Psa that can be done in the field. 

The test uses LAMP technology which is being developed for a number of pathogens and has the potential to deliver a diagnostic result within around 30 minutes in the field.

Workshop participants had the opportunity to use the test in the field on a Psa-affected orchard, to see how quickly and easily results could be produced. This test is not yet commercially available and still requires further development. However, it is good insight into tools that may be available to us in the near future. These tools may have applications for biosecurity surveillance and response.

This workshop illustrated one example of a field diagnostic test, the LAMP assay. However, we are aware that there are several other techniques being developed by other organisations in New Zealand and offshore. A group of scientists also visited Te Puke Plant and Food Research Centre this week to test another field deployable Psa field assay system.

More than 50 leaders from Bay of Plenty industries and organisations came together this morning with the Minister for Primary Industries, Nathan Guy, and Minister of Trade, Todd McClay, to celebrate the official launch of ‘biosecurity operational excellence’ at Port of Tauranga (POTL).

Guests were given an overview of the initiative and gained a good insight into the innovative ways Bay of Plenty industries and government are working together to better understand biosecurity risk at Port of Tauranga and to raise awareness amongst the Port community.

The group also observed the passenger biosecurity screening process of incoming cruise ship ‘The Arcadia’ where detector dog Ayla went to work sniffing out food risk items from more than 2000 disembarking passengers. The Arcadia arrived from Tahiti and Tauranga was its first port of call.

The project, which started as an exercise to better understand biosecurity risks at POTL, has a working group made up of committed Bay of Plenty sectors. They are:

  • Port of Tauranga Limited
  • Kiwifruit Vine Health
  • Ministry for Primary Industries
  • New Zealand Customs
  • Forest Owners Association
  • Bay of Plenty Regional Council
  • Fonterra, on behalf of the dairy sector
  • NZ Avocados

The programme is tailored to organisms and particular imported goods and pathways relevant to the Bay of Plenty. However, the vision has always been to develop this approach as a national model.
