Psa research update videos
20 September 2018

Continuing the battle on kiwifruit vine disease Psa, Zespri’s innovation team and KVH hosted a Psa R&D update on 21 August 2018 which saw scientists share with growers and industry insights into their research on Psa. From the Plant and Food Research new cultivars and rootstocks programmes, through to a yeast-based biological for preventing Psa that is currently being assessed by government officials for its suitability for commercial release, it was a good opportunity for growers to hear the advances in this space.

Videos of each research update are shared on the Zespri Canopy website here.

MPI to get tough on stink bug ships
20 September 2018

With the support of KVH, biosecurity officials at the Ministry for Primary Industries (MPI) are promising to take tough action against cargo vessels believed to be infested with the Brown Marmorated Stink Bug (BMSB) during the upcoming risk season.

If an arriving ship is infested with stink bug it will be prevented from discharging its cargo and directed to leave New Zealand. There is a very low threshold for determining contamination – MPI says if a single bug is found they will thoroughly investigate whether the entire vessel is contaminated. 

As with previous stink bug seasons, there will also be increased surveillance and inspection of arriving vessels and cargo from countries with established stink bug populations. Read more about what’s being done to manage the BMSB risk, detailed in the last KVH Bulletin here.

Don't be afraid to report suspect finds
20 September 2018

We understand that reporting a potential biosecurity threat can create anxiety for some growers, who may worry about potential implications or movement controls that may result.  The sooner you alert us to anything unusual, the more we can do to help you. Early detection is key to eradication – if we don’t report and miss this window, any one of a number of unwanted pests could establish and be a challenge we have to deal with forever.

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.

Biosecurity agenda at international kiwifruit meeting
20 September 2018

KVH Chief Executive Stu Hutchings discussed New Zealand’s biosecurity activities at the 37th International Kiwifruit Organisation (IKO) meeting in France last week.

Also attended by NZKGI and Zespri representatives, the annual meeting provides an opportunity for international counterparts from countries where kiwifruit is grown to share news and opportunities. Stu provided an update about progress in managing Psa in New Zealand, some information regarding copper resistance and our approach to managing other biosecurity risks.

As part of the trip, Stu witnessed first-hand the devastation that recent hail, frosts and flooding had caused and the large amounts of Psa that subsequently developed in some orchards following this. He also saw Brown Marmorated Stink Bugs (BMSB) at many sites. These pests are starting to be found in larger numbers on kiwifruit orchards in both the south of France and northern Italy, with associated fruit damage and fruit drop occurring. This was especially prevalent where orchards were close to soya or maize crops.

More information about these visits will be provided at the Kiwifruit Biosecurity Grower Day to be held Thursday 18 October, as part of Biosecurity Week.

Helping Boards respond to a biosecurity crisis
20 September 2018

Every Board must consider risk to their business, the impact it will have and how to mitigate it. But what happens when a risk has not been identified as significant and it hits? Biosecurity events have blindsided businesses over the years and the threats to our primary industries are increasing. These threats impact primary producers as well as their suppliers and customers.

How Boards can prepare for and react to crises of this nature was discussed last night at a Bay of Plenty Institute of Directors (IOD) panel event, specially put together to talk about biosecurity and why it is considered the number one risk to one of the largest sectors of our economy.

Facilitated by Graeme Marshall, Chairman of the Biosecurity Ministerial Advisory Committee and KVH Director, the theme for the evening was around asking business leaders and Governance members in the room ‘do you know exactly how your business would respond to the next big biosecurity incursion and will you be able to make robust and quick decisions?’.

On the discussion panel was John Loughlin, who as Chairman of Zespri when Psa hit the kiwifruit industry (and now Chair of the Meat Industry Association dealing with Mycoplama bovis) said there are a broad range of potential biosecurity incursions and some are better understood than others, which is why preparation is key.

The same key point was echoed by Ian Proudfoot, Global Head of Agribusiness for KPMG New Zealand, who discussed his perspective on the huge potential for growth in agribusiness in this country and how that could be heavily affected by a biosecurity incursion if not appropriately managed.

Overall says Graeme, the audience had a practical lesson on good governance from leaders who have experienced major biosecurity incursions and know that it’s important to be ready from day one; to activate response or business continuity mechanisms immediately; and demonstrate leadership.

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.

Recently KVH hosted a group of Japanese visitors with connections to Zespri’s ZGL operation. The group included nurserymen looking to better understand the New Zealand kiwifruit industry, Psa management strategies and with a particular interest in understanding the basis of the Kiwifruit Plant Certification Scheme (KPCS). These exchanges also help KVH share knowledge and insight around biosecurity pests that may be present in other countries growing kiwifruit.

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.
