Joining forces at workshop on biosecurity
6 September 2018

Last week KVH attended a biosecurity workshop in Edgecumbe, organised by Federated Farmers for agricultural contractors. A panel discussion was held to create dialogue on how biosecurity risks can be managed on-farm with speakers from DairyNZ, Bay of Plenty Regional Council, the Ministry for Primary Industries and KVH. Sharing knowledge between sectors was one of the key learnings from our Psa response and this was a great opportunity for an open conversation to learn from each other.

Know your orchard weeds: cleavers
6 September 2018

Orchard owners, managers and their teams are, year-by-year, battling a range of weeds within the orchard, ensuring they don’t take over.  It’s good to know a bit more about the plants we often battle.

You know early spring has arrived when the weed known as cleavers (Galium aparine) grows up into and from shelter belts.  This scrambling annual weed is a native of temperate Europe and Asia and was one of our earliest established weeds – first noticed about 140 years ago.  It is a nuisance plant but one that can completely smother lower trunks and branches of especially shelter trees.

Cleavers is one of those “sticky” plants. Stems are square with inconspicuous hooked prickles on the four corners. Leaves are arranged in groups of five to eight around the stem and have backward pointing hairs which enable the leaf to readily cling to clothing. The green fruits are small (5mm across) and densely covered in hooked bristles that again stick to clothing, fur or wool.

The stems, which can grow to 2m or more long, tend to break from the parent plant very easily. 

Cleavers is often confused with the native biddibiddi (Acaena novae-zelandiae) – also known as piripiri - but it has very much smaller fruits or bidibids.

The hooked bristles are a very effective mechanism to ensure the spread of cleavers. Most orchardists have brushed off dozens of small round fruits from their jerseys or shirts before going indoors.

Cleavers are quite easily hand-weeded. Just pull the stems, trace back to the rooted portion and pull this from the ground – best undertaken while the ground is damp. It is more persistent where the broken stems and fruits are left within a shelter belt.  Persistent hand weeding will eventually reduce infestations.

Glyphosate is effective but the addition of a penetrant or spreader is essential.  Any over-spray could harm other desirable plants, so care is essential.

KVH thanks Tim Senior, Bay of Plenty Regional Council, for some information reproduced here.

Orchard conversion to male-only orchard solves unmanaged predicament
6 September 2018

KVH has a responsibility under the National Psa-V Pest Management Plan (NPMP) to ensure that kiwifruit orchards meet required management standards.

The owners of a small Tauranga orchard have decided to lease it to a pollen producing company, and so meet KVH requirements around orchard management.

Owners were in limbo after the small Hayward orchard had only returned a profit in two years out of the last seven.  It remained unpicked and unpruned and so in breach of KVH requirements that kiwifruit orchards be picked by 1 July; pruned and tied down (female vines) by 1 October yearly; and a crop protection product, effective against Psa-V, applied at least yearly.

Within a few weeks of KVH involvement vines were cut back to the trunks and grafted with male scion wood.  All unpicked fruit and canes were mulched.  The trunks have remained on the property for later disposal (burning or burial).

The unpicked fruit were a definite problem as birds were feeding upon it and potentially spreading seed into nearby forest or bush areas.  The orchard could have been a source of Psa inoculum effecting nearby orchards.

KVH appreciates the cooperation of all concerned to swiftly remedy the unmanaged state of the orchard.

If you are aware of any unmanaged or abandoned kiwifruit orchards, please contact KVH.  Amicable solutions are often possible.

New seasonal wall chart
6 September 2018

The Psa-V Seasonal Management Wall Chart 2018-19 is out now and an A2 poster copy is included in your latest Kiwiflier (you can also download a copy from the KVH website or contact us if you’d like extra copies sent to you). A key feature of the wall chart is the KVH Recommended Product List, which sets out the upcoming seasons approved products for protection against Psa, their year-round application rates and permitted use periods.

Key changes to this season’s wall chart are:

·         Additional descriptive information about the size and length of leaves and shoots when applying products.

·         More emphasis on cultural management of Psa, including making information about products for sanitising tools and pruning more promintent.

Any changes or updates made to the chart and product list during the 2018/19 season will be made to the online versions and will be notified via the KVH Bulletin.

Spring Psa symptoms
6 September 2018

With sap on the rise and budbreak for many Gold sites already sitting at five percent or more, growers are highly recommended to begin Psa monitoring rounds across high risk areas of their orchards.

These include areas where symptoms have been seen previously, high traffic areas, blocks exposed to prevailing winds and areas which are cold and frost-prone or water-logged. Monitoring will inform the need for infection removal and will assist planning of Spring spray programmes. For high-risk sites where bactericides may be required weed sprays should be applied to ensure conditions for application of these products are met. Read more about mandatory orchard monitoring rounds here.

KVH has had reports of white exudate seen during grafting in some new development blocks, and we remind growers that young plants are more vulnerable to Psa so take care to monitor and protect these with directed spray programmes and ensure good frost protection is in place.

Copper should be applied at winter rates immediately prior to budbreak to all vines to protect emerging growth and then as new growth extends repeat applications should be at summer rates.

Reporting Psa symptoms
6 September 2018

If Psa-like symptoms are found for the first time on your orchard report these to KVH on 0800 665 825. Growers can also contact their packhouse technical representative for advice and sample collection if required. Hill Laboratories carry out routine Psa testing weekly on Wednesday only but can process samples urgently at KVH request.

KVH continues to pay for lab testing in Exclusion regions (Far North, Whangarei and South Island). Other testing may be approved on a case-by-case basis.

If suspicious symptoms are found, follow processes in the KVH Information sheet: Psa sample collection and testing.

Mandatory orchard monitoring
6 September 2018

All growers in Exclusion regions and all growers with ‘Not Detected’ orchards in all regions are required to carry out a round of mandatory monitoring between 15 September and 15 October, with results due to KVH by 31 October. Monitoring is a critical component of establishing Psa-presence, location, and volume so that it can be managed.

An online monitoring form is available on the KVH website here. Please call KVH on 0800 665 825 if you have any questions or require assistance to complete the online form.

Why is monitoring so important? Growers in Exclusion regions and with ‘Not Detected’ orchards need to monitor vines for Psa early, so we can act if anything is identified and protect the rest of their orchard as well as nearby growers.

Regular orchard monitoring enables growers to become familiar with their vines. It’s about learning what is usual, and what isn’t. Nine times out 10 when you see something odd it will be nothing, and that’s good, because it means that the one time it’s something of concern, we’re finding it. The sooner we learn about something unusual the more we can do to help.

KVH has developed ’Kiwifruit’s Most Unwanted’ information and fact sheets, which are available on the KVH website. While these organisms are considered the greatest potential threats to the kiwifruit industry, the next incursion we face could be another damaging pest or disease not yet on our radar. Look out for plants displaying any unusual symptoms and pests not commonly seen or identifiable to monitoring staff.

Our most unwanted pests
6 September 2018

Fruit flies and Brown Marmorated Stink Bug (BMSB) are considered two of the biggest biosecurity threats to the kiwifruit industry and from September they are both in their highest-risk period for entry into New Zealand. A quick reminder of the damage these unwanted pests can do and what to look out for:

Fruit flies:

·        High likelihood of entry - has crossed our borders many times before.

·        Extended spread in Australia.

·        Severe market access restrictions, especially for Queensland Fruit Fly, which is not present in nearly all kiwifruit markets.

·        The high-risk season is now. Be on the lookout for the flies as well as the larvae in fruit.

BMSB:

·        High likelihood of entry – particularly in shipping containers, cars and machinery, and passenger luggage.

·        Significant production impacts for a wide range of crops.

·        Early detection needed because this pest is extremely difficult to eradicate. It’s also a major nuisance pest infesting homes.

For more information on these and other biosecurity threats to the kiwifruit industry, see the fact sheets and images on the KVH website.

Managing the BMSB risk

Tighter import rules

As mentioned in the last Bulletin, KVH continues to advocate strongly on behalf of the industry for strict biosecurity border controls which will make it harder for the Brown Marmorated Stink Bug (BMSB) to make its way here.

There have been additional measures for the high-risk Vehicles, Machinery and Equipment Pathways introduced. The measures now target risk goods from 16 countries (Austria, Bulgaria, France, Georgia, Germany, Greece, Hungry, Italy, Liechtenstein, Romania, Russia, Serbia, Spain, Slovenia, Switzerland and the USA).  New measures have also been introduced for vehicles from Japan after the high number of interceptions on this pathway last season.

We are pleased that the Ministry for Primary Industries (MPI) has also announced mandatory treatments applied to all containers from Italy (introduced last year) will again be applied this high-risk season as well as during the 2019/2020 season. MPI have increased the duration of this treatment period so that it extends from September through until the end of April.

KVH applaud MPI’s efforts to introduce these measures and push the management of risk offshore resulting in much greater protection to our industry.

Research learnings

Professor Max Suckling from Plant and Food Research and the University of Auckland has published another video on his research in Italy, using novel non-chemical techniques to disrupt BMSB mating. This is a more technical video that can be viewed here.

i-Site displays

This summer KVH is stocking the Mount Maunganui and Cruise Terminal i-Sites with biosecurity flyers raising awareness about high-risk pest threats (mainly BMSB) potentially hitchhiking their way across our borders. The i-Sites double as ticketing offices are often the first point of call for visitors and cruise ship passengers wanting to know more about the region and plan their time here.

Biosecurity buzz at roadshows
6 September 2018

KVH took part in the recent Zespri Grower Roadshows, meeting and speaking with growers about new developments and recent biosecurity activity we’ve been undertaking.

Chief Executive Stu Hutchings presented at the roadshows on Spotted Lanternfly (SLF), a pest native to China that is now wreaking havoc in Pennsylvania, USA. KVH Board Member Simon Cook recently visited the state to learn more about their incursion – read more about what he saw, and the work being done by KVH and the Ministry for Primary Industries to better understand the potential threat SLF poses to our industry.   

Heading into the high-risk season for Brown Marmorated Stink Bug (BMSB), Stu also shared with growers a video demonstrating the impacts of the bug on kiwifruit in Italy. The video helps us gain a better understanding of what Italian growers are facing and provides a practical on-orchard view of the severe damage BMSB can do. Watch the vide on the KVH YouTube channel here.
