KiwiNet making a difference in the fruit fly fight
2 May 2019

KiwiNet – the kiwifruit industry’s official team of selected people who champion biosecurity readiness and coordinate the deployment of kiwifruit industry resources into bioseucrity responses – has been heavily involved in the Auckland fruit fly response.

There have been more than 165 staff days so far contributed by KiwiNet members, who have used their skills and expertise to help with trapping, ground surveying, fruit collection, and public awareness activities.

Profiles of two team members have been published, sharing their experience working on the frontline – read all about Lori from OPAC and Sheryl from EastPack.

BMSB season comes to a close
2 May 2019

Since the start of the high-risk season in September 2018 there have been 212 live BMSB detected.

Read more in the latest Brown Marmorated Stink Bug (BMSB) risk update.

The update includes latest interception data, surveillance information, and an update about ongoing work alongside Australian officials to align activities.

We’re at the end of the highest risk time of year for BMSB but there is never zero risk. Continue to be on the lookout and report anything unusual to KVH or the Biosecurity New Zealand hotline. There are handy ID guides and videos that demonstrate the impact this nasty bug could have on kiwifruit orchards – and our lifestyles – on the KVH website.

Passenger and mail biosecurity review released
2 May 2019

Early this week the Ministry for Primary Industries (MPI) announced the findings of an independent review of its biosecurity passenger and mail controls at the border.

The review was commissioned after fruit fly was first detected in Auckland earlier this year and overall has found that border services in the mail and passenger pathways protect New Zealand well.

The review also notes some significant challenges the border is under and that ongoing improvement is essential. Several recommendations have been made and are now being considered, including:

·         fast deployment of new scanning technologies for suitcases and rapid scanning of hand baggage

·         more development of public awareness measures, such as smartphone-enabled digital tools for arriving travellers

·         separating arriving passengers carrying commercial quantities of food from other international travellers

·         extending a scheme involving the pre-clearance of approved food packages carried by passengers from Tonga and imposing stiff penalties for any breaches

·         charging cruise ship operators that are not covered by the existing accreditation scheme for costs relating to biosecurity services

·         improved access to intelligence to aid risk assessment decisions regarding express freight

·         introducing new scanning technology at the mail centre.

The recommendations reinforce a lot of things that are already on MPI’s radar and they will look at how they can fit these into their existing work programme. There are also recommendations expected to come from the separate cargo review underway.

KVH welcomes and supports the findings of the review. In our ongoing discussions with MPI we will refer to the official findings to help guide decision-making and ensure all efforts are undertaken to continue protecting our borders and the kiwifruit industry from exotic threats.

The worst invasive species the US has seen in 150 years
The Spotted Lanternfly is considered by the U.S. Department of Agriculture to be the worst invasive species in the last 150 years. That's because they threaten products from wine to apples, lumber and craft beer. Industries that amount to $18 Billion in the state of Pennsylvania, alone.

Waihi weather station data now available
2 May 2019

A new weather station has been installed at Fisher Road to support Waihi growers.

The station was installed by Hortplus and extends the network of weather stations across the country.

Waihi growers can now receive tailored weather and Psa risk data for their region by using the Psa Risk Model on the KVH website, with access also available to other tools including the growing degree day calculator, chill unit calculator, hourly and daily weather data, and weather forecasting.

KVH thanks Hortplus for the installation of this weather station. Thanks also go to those who helped to source a suitable location - in particular, the grower now hosting this very valuable addition to the Psa Risk Model network.

Growers can register online to use the model if they don’t currently have a login, or email info@kvh.org.nz for more information.

Psa protection for harvested and development blocks important
2 May 2019

An observant Northland grower forwarded this image (right) to KVH from his new development block, showing Psa exudate developing on the underside of spotted Bruno leaves.

The block had developed some leaf spot symptoms in late spring, following a period of high winds and rain, but new leaders and laterals established throughout summer had remained clear of infection. This recent reactivation of Psa on the edge of leaf spots illustrates how Psa multiplication is favoured as temperatures drop through autumn, and an immediate application of winter rate copper was recommended to avoid infection spread.

Growers and outdoor nurseries are reminded to stay focused on protecting young rootstock and replacement plants through autumn as these are most vulnerable to Psa infection. Winter rate copper is recommended and additionally the biologicals Kiwivax (applied as a soil drench) and Botryzen are suited to autumn use. Refer to the KVH recommended product list.

Also apply copper to mature blocks immediately after harvest to protect fruit stalks and leaf scars. The Psa risk model currently predicts a good spray window available through to early next week for most regions.

New fruit fly detection
2 May 2019

Controls on the movement of fruit and vegetables in the Auckland suburb of Northcote have been reintroduced following the detection of a further Queensland Fruit Fly (QFF).

The single male fruit fly was found late last week in one of the network of traps which remained in place following the discovery of six other fruit flies in the area in February/March.


This latest fly showed indications it was relatively elderly for a QFF, suggesting it may be from the same group as the earlier detections. There is no evidence of a breeding population.

While it is disappointing there has been another detection it does demonstrate that the trapping and surveillance systems in place are working.

Activity has increased in the reinstated Controlled Area Zone, including extended trapping and the collection of fallen fruit, as well as the return of signage and wheelie bins for residential fruit disposal. Detailed maps of the controlled areas and a full description of the boundaries and rules are available on the
Biosecurity New Zealand website.

Kiwifruit growers should talk to their post-harvest providers if they have any questions about what the impacts to them might be due to movement controls or export restrictions.

If you require support you can contact NZKGI or 
visit their website to learn more about the support network available.

Summary of finds: Single male QFF have been found in separate surveillance traps in the Auckland North Shore suburbs of Devonport (one single fly) and Northcote (seven single flies over an extended period of time). Three Facialis flies have been found in Otara.

Budwood
18 April 2019

KVH has updated the KVH Protocol: Budwood which is now available on the KVH website.

The movement of plant material such as budwood presents the greatest risk of spreading pathogens over long distances. This is relevant to Psa, as well as other known (and unknown) pathogens that may be present in the plant. The best practice to reduce spread of pathogens is to source budwood from your own orchard for use on the same orchard. However, where this is not possible, the budwood protocol outlines the requirements to prevent spread of Psa under the National Psa-V Pest Management Plan (NPMP), and recommended practices to reduce the likelihood of spreading other pathogens.

Changes to the protocol have been highlighted in yellow and include the following;

  • Budwood must not be collected from material left on the ground after pruning.
  • The addition of recommended practices to manage risk of spreading pathogens:
  1. Monitoring vines throughout the year
  2. Tagging symptomatic vines so they can be avoided when collecting budwood - and avoiding any adjacent vines in any direction.
  3. Notifying KVH if a there is not an obvious cause for any unusual vine symptoms.

Phytophthora workshop
18 April 2019

Phytophthora are a genus of pathogens responsible for some of the most significant biosecurity incursions around the world. They are the causal agent for numerous diseases, including Kauri dieback disease. Phytophthora could have disastrous impacts on New Zealand’s horticulture, forestry and natural ecosystems. There are hundreds of Phytophthora species around the globe and new species are discovered all the time. The risk to our industry is largely unknown, but globally phytophthora risk is considered to be increasing.

Therefore, KVH and MPI are undertaking a joint readiness programme to consider how we should prepare for an incursion and how we would respond should this occur. To launch this preparedness for phytophthora, a workshop was held last week to brainstorm current knowledge, response scenarios and knowledge gaps to be filled by research.

The workshop was also attended by members of Zespri and Plant and Food Research and the outcomes will form the basis of a GIA readiness plan using a similar process to what we did previously for Brazilian wilt, Ceratocystis fimbriata.

Reminder that footwear can spread pathogens
18 April 2019

 MPI’s Border Space newsletter contained a photo of dirty jandals that were presented at the border by a traveller who was entering New Zealand to work in horticulture. These jandals had been used on a tomato farm in the Pacific Islands the previous day and could have contained various soil-borne pathogens. Fortunately, in this instance the traveller did the right thing and declared the dirty footwear to border staff upon arrival. The items were then cleaned appropriately.  

A previous study by AgResearch in 2010 demonstrated that a single gram of soil on an international aircraft traveller’s footwear had a greater than 50% chance of containing a regulated organism. With that in mind, the incident is a useful reminder that we ensure all visitors to our orchards enter with clean footwear, particularly if they have recently been overseas or to other regions of New Zealand.

Auckland fruit fly response update
18 April 2019

The Queensland fruit fly was last detected in Northcote on 14 March. This find led to an increase in the on-the-ground operational response, including removal of fallen fruit from backyards, inspections of compost bins, and baiting in fruit trees to attract and kill adult flies, in particular females.

Movement restrictions for fruit and vegetables were lifted in Devonport on March 22 and Northcote on April 12.

Biosecurity New Zealand says: “All operational activities, including baiting, have been completed. However, as a precautionary measure, we will be keeping in place an enhanced network of fruit fly traps for an extended period. If fruit flies are present, these traps will detect them.”
