Most unwanted pest data released
18 May 2017

The highest risk period for Brown Marmorated Stink Bug (BMSB) and Queensland Fruit Fly (QFF) is coming to an end and the Ministry for Primary Industries (MPI) has released data summarising interceptions and interventions for the 2016/17 period.

KVH has made both the BMSB and QFF reports available online. Making data like this available is something that we’re committed to and have been working closely with MPI on this season to ensure correct, up-to-date information is shared that helps demonstrate the work taking place at our borders that industry is playing a key role in.

Although we’re not in the high-risk period at the moment there is never zero risk – growers are reminded to be on the lookout for these serious pests year-round. As mentioned in the last Bulletin, BMSB has been found in Chile. It’s the first southern hemisphere detection and increases the risk to us here as our seasons are compatible and BMSB could arrive year-round.

Potential new frost fan technology
18 May 2017

KVH supports use of all technology available to growers that will avoid frost damage to vines which often results in Psa infection.

Japanese representatives of a company that develops frost protection fans are in New Zealand this week meeting with growers about their new fan systems which they first presented at the Te Puke A&P show in February.

Their fans are used widely across high value tea plantations in Japan.

The team first visited KVH and Zespri two years ago to learn more about New Zealand kiwifruit growing, climatic conditions, and how they may be able to use their technology to support orchard management.

Trial fans have since been put in two kiwifruit orchards in the Te Puke region which will be tested again this year. A trial that has been in place for three years at a vineyard in Martinborough is proving successful. The fans are most applicable to small unprotected blocks or perhaps large blocks with pockets unprotected by current windmills. Blocks with challenges re water consents or looking to avoid water frost protection due to soil issues may also benefit.

Visit Fritons to find out more about the new technology.

Importance of good hygiene practices highlighted by myrtle rust discovery
15 May 2017

On Friday afternoon the Ministry for Primary Industries (MPI) and New Zealand Plant Producers Incorporated (NZPPI) announced that a legal notice has been issued which makes it mandatory for nurseries, retailers, and plant transporters to comply with NZPPI Myrtle Rust Risk Management Protocols.

In short, the notice requires that hygiene, containment and management protocols are followed to increase the chances of early detection and lower the possibility of any further spread of myrtle rust.

Although myrtle rust doesn’t affect kiwifruit vines this is an important and timely reminder for all growers that good hygiene practices should always be followed to help manage biosecurity threats.

Unwanted pests and diseases are easily spread through infected plant material and unclean machinery, tools, people and vehicles. Good hygiene practices are essential to help prevent their spread between vines, orchards and regions.

KVH hygiene recommendations are available in detail online. They key points are: 

·         Check and clean tools, vehicles, machinery, people and clothing.

·         Ensure everything that comes on to your property is free from soil  and plant material.

·         Sanitise highest risk items and wash down dirty areas.

·         Share information about biosecurity measures with your staff and contractors.

Myrtle rust could affect any native or exotic myrtle plants on your property – like feijoa or guava plants for example. Before harvest check these plants for any symptoms of the disease. You can read more about myrtle rust on the KVH website or visit the NZPPI website to view a complete list of all native and exotic myrtle plants in New Zealand.

If you see any of symptoms of myrtle rust or anything else unusual, call the MPI exotic pests and diseases hotline on 0800 80 99 66. Take a photo but don't attempt to touch or collect samples of myrtle rust as this may increase spread of the disease.

Myrtle rust disease discovered in New Zealand
12 May 2017

The Ministry for Primary Industries (MPI) has confirmed the presence of the myrtle rust plant disease on mainland New Zealand for the first time, in Kerikeri.

MPI, councils, the Department of Conservation, industry and iwi are all working together to contain the disease.

What is myrtle rust?

Myrtle rust is a fungal infection that can travel long distances in the wind and attacks plants of the myrtaceae family. It could affect iconic New Zealand plants like pohutukawa, kanuka, manuka and rata, as well as commercially-grown species such as eucalyptus, guava and feijoa.

What to look out for

Although myrtle rust doesn’t affect kiwifruit vines this is an important and timely reminder for all growers to look out for symptoms on their native myrtaceae trees. Look for:

• bright yellow powdery eruptions appearing on the underside of the leaf (young infection)
• bright yellow powdery eruptions on both sides of the leaf (mature infection)
• brown/grey rust pustules (older spores) can appear on older lesions
• leaves may become buckled or twisted and die off.

If you see any of these symptoms call the MPI exotic pests and dieases hotline on 0800 80 99 66. Take a photo but don't attempt to touch or collect samples as this may increase spread of the disease.

A myrtle rust fact sheet is available on the MPI website and there is also a lot of guidance available on the New Zealand Plant Producers site including a complete list of all native and exotic myrtle family plants in New Zealand.

We were delighted to spot a biosecurity message at the bottom of each page of a lucky travellers Air New Zealand e-tickets recently.
 
The Ministry for Primary Industries (MPI) worked with the airline to champion key biosecurity messaging that is clear, simple, and because it’s in bright yellow it’s also hard to miss. Having key organisations like Air New Zealand onboard is just what we need to keep seeing as part of raising the profile of biosecurity at the border.

Rules for importing kiwifruit seed
4 May 2017
Thanks to information provided by a local grower, KVH was recently alerted to an international website offering a range of kiwifruit seed varieties for sale. This is concerning because buying seeds online for import into New Zealand could risk introducing a plant disease.
 
KVH has worked with the Ministry for Primary Industries (MPI) to confirm the rules around importing kiwifruit seed and ensure MPI enforcement staff are aware of the site. 
 
There are strict rules around importing any kiwifruit seed. Seed intended for growing requires a permit to import and phytosanitary certificate. It must be imported into post entry quarantine where it will be grown and checked for a range of viruses and other plant disease organisms.  No seeds will be given biosecurity clearance; only plants which have been inspected and tested will be eligible for clearance.
 
MPI enforce all requirements and investigate any report of kiwifruit plants grown from unapproved seed imports. 
 
Please alert MPI if you are aware of any unapproved kiwifruit seed imports by calling the MPI exotic pest and disease hotline on 0800 80 99 66.

Do not pick fruit after spraying with Actigard
4 May 2017
Fruit left in the canopy after harvest should not be picked for home use or sale if a post-harvest Actigard spray has been applied. 
 
Syngenta advises that after spraying, fruit residues will exceed the local Maximum Residue Level (MRL) for Acibenzolar-S-Methyl (set at 0.02ppm). All domestically-produced food and food imports sold in New Zealand must comply with these Food Safety rules.  While the residue from the spray is unlikely to have any serious health impacts but it is important that product registration guidelines are always met.
 
A viable alternative is to get in quick before the sprayer or source reject fruit from post-harvest suppliers.

Keeping imported kiwifruit pest free
4 May 2017
Readers of the KVH Bulletin may recall that over the past few years, KVH has been advocating for tighter controls on the import of Italian kiwifruit to reduce the risk of White Peach Scale (WPS) entering our borders. We have also been working with kiwifruit importers to ensure they are aware of this threat and measures they can take post-border to reduce risk.
 
While these discussions have not resulted in changes to the Import Health Standard, we are pleased to report that interceptions of WPS have declined significantly over the past season despite a similar level of infestation reported offshore. This is a great result and reflects measures that both the Ministry for Primary Industries (MPI) and importers have taken in dealing with Italian counterparts to ensure fruit arriving in New Zealand is free of unwanted organisms. 
 
This season there were almost 900,000 kilos of kiwifruit was imported in 31 consignments, which were all inspected by MPI at the border. Only two of these consignments were found to have WPS, and were fumigated to remove biosecurity risk. This compares to 18 out of 46 consignments – or 39% - last year. 
 
KVH and Zespri are also funding research being conducted in Italy to better understand cold tolerance of WPS and the ability of these organisms to reproduce following long periods of cold storage. This research is ongoing and the outcomes will support further actions to reduce risk. 
 
WPS is regularly intercepted by MPI at our borders. This pest has caused considerable damage to Italian kiwifruit orchards with production losses of up to 20% in some years. WPS infects bark, fruit and leaves of plants. In severe cases it appears as white, cottony masses encrusting the bark of the tree. Trees which are heavily infested can become stunted and young plants can die very quickly after infestation. Read the KVH factsheet to learn more about identifying and controlling WPS.

Learning more about Psa across the world
4 May 2017
Early last week KVH and NZKGI hosted a group of growers from Spain and Portugal to learn more about the challenges and experiences of growing kiwifruit in other regions.
 
KVH presented to the group on Monday and shared information about Psa in New Zealand, including our history with the disease and control efforts that are now in place. Most of the group are Hayward growers and were thankful for the interesting information shared with them that they can apply in their own local areas.
 
The growers shared with KVH that in several orchards in the coldest areas of Galicia (in the north west of Spain and the main production area of the country) and northern Portugal, where during January temperatures were as low as -7 degrees, large symptoms on trunks and leaders were recorded before budburst in February and early March. 
 
Unlike previous years, symptoms appeared more frequently in female plants. 
 
In the more temperate zones however there were practically no symptoms. 
 
There was a good number of cooler hours last winter, especially in December and January, with extreme temperatures and low rainfall.  Shoot dieback and cane collapse have been detected in some plants.
 
Both regions are currently in pre-flowering (flowering in Hayward will occur in about a fortnight from now) and they are seeing spots on leaves and early signs of sepal staining on buds. The weather has been dry over spring and as a result symptoms have not yet been serious. Rainfall was expected late last week, which is likely to lead to an increase in symptoms.
 
KVH will remain in contact with the group to ensure we keep up-to-date with seasonal changes to Psa.
