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.

Consultations on import standards
18 April 2019

KVH continues to advocate strongly on behalf of the industry for strict biosecurity border controls. We back proposed Ministry for Primary Industries (MPI) changes to rules for vehicles and sea containers, which will make it harder for the Brown Marmorated Stink Bug (BMSB) to make its way across our borders.

MPI is currently consulting on two recently-reviewed Import Health Standards (IHS) – one for the import of vehicles, machinery, and equipment; and the other for the import of sea containers.

Proposed changes include extending the list of countries that have requirements to treat vehicles, machinery and equipment imports before they arrive in New Zealand. At present, 18 countries have pre-treatment requirements. The proposed new list will increase to 33 countries.

All imported cargo related to vehicles will need to be treated offshore, including sea containers. In the past, only uncontainerised cargo required treatment before arrival.

MPI also intends to refine some of the offshore management requirements under the existing import standard for vehicles and has worked with the Australian Department of Agriculture and Water Resources to align measures, making it easier for traders and shippers to comply.

KVH will be making submissions on behalf of the kiwifruit industry, supporting increased measures to protect our industry. Growers are also able to make their own submissions.

The consultations run through to Monday 3 June. Click here to read more about proposed changes relating to vehicles, machinery, and equipment. Click here to read more about proposed changes to the import of sea containers.

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.” 

 

The latest fruit fly risk update has been published on the KVH website.

As well as the finds in Auckland, the fruit fly update details detections at the border, the national surveillance programme, and recent international responses to this unwanted pest.

KVH risk updates are published every month.

Help dig out new wood-boring beetle
4 April 2019

The public is being asked to report any sign of the granulate ambrosia beetle.

This unwanted pest has been detected in five Auckland areas since 20 February 2019. It is the first time the beetle - regarded as a serious pest overseas - has been found here. Evidence to date suggests it may have been in the country for at least two years. 

Kiwifruit is not known to be a host, but it does feed on a wide range of broadleaf trees and can spread fungal diseases.

Biosecurity New Zealand is currently assessing the potential risk from the beetle and is asking the public to report any possible sightings so that more can be learnt about whether New Zealand has a wider population.

The beetle resides under bark, making it difficult to detect. A tell-tale sign is distinctive protrusions of frass (compacted sawdust) from bark that look like toothpicks. They are caused by the beetles pushing frass out of tunnels bored into the trees. Other symptoms include sap oozing from the tunnel entrances and branch dieback.

Biosecurity New Zealand and local authorities are working together to identify the extent of the spread, inspect known host trees, and place lured traps around the detection sites in Auckland.  Industry groups are also learning more from offshore researchers about risk, containment, and long-term management options. 

KVH is closely following the response and will update growers of any developments that indicate the kiwifruit industry could be impacted by the beetle or pathogens it could spread. 

If you think you may have seen the granulate ambrosia beetle or any sign of frass on trees, take a photo and call Biosecurity New Zealand's exotic pests and diseases hotline on 0800 80 99 66. Read more about the beetle and view the new fact sheet, including images, on the Biosecurity New Zealand website.

No new fruit flies
4 April 2019

Since our last update Friday 22 March, there have been no changes to the Auckland fruit fly response situation, and no further flies have been detected.

Importantly, there has not been any evidence of a breeding population found either – that means to date no eggs, larvae, or pupae have been found.

Controls on the movement of fruit and vegetables, and a baiting programme continue in Controlled Zones in Northcote. The last detection there was of a Queensland Fruit Fly (QFF) on Thursday 14 March. Teams on the ground have been removing fallen fruit from backyards, inspecting compost bins, and placing bait on fruit trees to attract and kill adult flies, in particular females. The bait is made up of a protein to attract adult fruit flies, and a very low concentration of insecticide to kill the flies. The baits are toxic to fruit flies but are safe around people and animals.

KVH continues to Chair the Fruit Fly Council - a governance group made up of impacted industry sector representatives under the Government Industry Agreement (GIA) partnership - and work alongside Biosecurity New Zealand in this response. We are involved in response decision-making processes ensuring the interests of the kiwifruit industry are represented and we will keep growers updated if there are any new developments.

Kiwifruit growers should talk to their post-harvest providers if they have any questions about what the impacts to them might be due to continued 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 (six single flies over an extended period of time). Three Facialis flies have been found in Otara.

Top tips for harvest hygiene
4 April 2019

Harvest season presents a high-risk period for spreading Psa or other biosecurity risks between blocks, orchards and regions because of the numbers of vehicles, machinery and people movements involved.

Growers are responsible for protecting their orchards, and others, by ensuring the movement of harvest equipment, people and bins onto and around their orchard is minimised.

Top tips for harvest hygiene:

·         Clear loadout areas of weeds.

·         Clearly mark parking and hygiene control areas.

·         Allow only essential vehicles into the production area.

·         Limit access to established roads and tracks and use free orchard access signs available from KVH or your local pack-house.

·         Make sure contractors and staff understand your hygiene requirements.

·         Check all equipment (harvest bins, harvest machinery, picking bags etc) coming on to your orchard has been cleaned and sanitised, and is free of plant and soil material.

·         Ensure people check that clothing, particularly headwear and footwear, is free of plant material on entry and exit.

·         Do not allow workers to bring imported fruit onto the orchard.

With extra people coming and going through orchards more pairs of eyes can be on the lookout for unusual vine symptoms or pests. Ensure everyone knows to report the unusual to either KVH on 0800 665 825 or Biosecurity New Zealand on 0800 80 99 66.

Harvest hygiene guides online
4 April 2019

As we head into harvest season, a reminder that KVH has biosecurity pocket guides available which have been translated into several languages to promote harvest hygiene messages.

These tools are quick, step-by-step visual reference guides for use by all growers, on-orchard harvest workers, auditors, transporters, post-harvest and harvest contractors.

Harvest season presents a high-risk period for spreading Psa or other biosecurity risks between blocks, orchards and regions because of the numbers of vehicles, machinery and people movements involved. Everyone in contact with orchards at this time of the year must be fully aware of best practice orchard hygiene.

Last chance for free NZQA biosecurity course
4 April 2019

If you’re in Pukekohe, this is your last chance to attend a free biosecurity micro-credential course. Developed by the Primary ITO and industry, it aims to enhance industry biosecurity capability, and covers biosecurity principles, on-farm practices, and an assessment component.

Designed for grower owner-operators and supervisors/managers, the NZQA Level 5 course will give you an understanding of biosecurity, risks present on your orchard, how to prioritise and manage them, and how these practices can be put in place or improved.  

As the programme is still being tested with industry groups there is no cost for participating, all materials and catering will be provided.  Participants agree to take part in the course, complete the assessment afterwards, and provide feedback.

The final pilot course will take place in Pukekohe next Monday, 8 April. As there are limited places, please contact Anna Rathé at Horticulture New Zealand to secure your place.

Moderate Psa infection risk predicted
4 April 2019

The Psa Risk Model currently predicts moderate Psa infection risk for next week in most regions. This reflects increased Psa risk with autumn weather and provides a reminder to growers to again consider Psa management plans, particularly for recently harvested blocks and younger plantings.

For harvested blocks, best practice is to apply a copper product to protect all fruit scars. Winter rates of copper can be applied and Actigard may be added to the tank if there is no risk of spray drift to neighbouring unharvested blocks.

Apply copper alone if there is any risk of drift and then plan to follow up with an Actigard spray when neighbouring blocks have been harvested. Good spray coverage is essential and remember that for Actigard uptake leaves need to be active, so a good cover of green leaves in the canopy is needed. If blocks have suffered extreme drought stress apply copper on its own.

Also a reminder to trim out thick, hairy, late season male growth as this can be highly susceptible to Psa infection in autumn, particularly if frosted. Apply copper after male trimming rounds to protect wounds.

Auckland fruit fly detections update
21 March 2019

Two further male Queensland Fruit Flies (QFF) were found in Northcote last week, bringing the total to six. One of the new finds was inside the current Zone A and the other was in Zone B.

The latest finds mean an expansion of Zone A in Northcote and associated restrictions on the movement of fruit, vegetables and green waste. It also means an increase in operational response activities. Teams on the ground have been removing fallen fruit from backyards, inspecting compost bins and placing bait on fruit trees to attract and kill adult flies, in particular females.

The bait is made up of a protein to attract adult fruit flies and a very low concentration of insecticide to kill the flies. It’s similar to how people bait wasps in their backyards. The baits are toxic to fruit flies. Every precaution is taken to make sure the baits are safe around people and animals.

There have been no further finds of QFF in Devonport since the only find there on Thursday 14 February. However, because of the proximity to Northcote, movement controls and trapping have continued – this will reconsidered within the next few days.

No further Facialis fruit fly have been found in Otara (three in total have been found here).

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.
