Brown Marmorated Stink Bug

The Brown Marmorated Stink Bug (BMSB) is the kiwifruit industry’s second-most unwanted biosecurity threat after fruit flies; and the risk of it entering New Zealand is considered extreme.

The BMSB is able to hitchhike on inanimate objects such as cars and shipping containers. If it were to enter New Zealand it would have no problem establishing due to New Zealand’s highly suitable climate and abundance of host material. Its entry and establishment would result in significant production impacts to many horticultural industries.

The high risk and potential consequence of BMSB have made it a priority for biosecurity readiness activities for both KVH and the Ministry for Primary Industries (MPI).

BMSB preparedness

KVH is working with Zespri, MPI and the wider kiwifruit industry to ensure we are all prepared for BMSB, if it were to arrive and establish here. This includes running regular simulation exercises, hosting workshops, and developing joint workplans for how we would manage an incursion and long term response.

Read the BMSB Readiness Plan (A) for information about how the industry is ready for a New Zealand incursion. Read the BMSB Readiness Plan (B) for information about long term management considerations should BMSB establish in New Zealand.

Read the BMSB kiwifruit growers guide to long-term management. The guide outlines all the things growers should do on-orchard and how to do them when managing BMSB long-term.

In August 2018 the New Zealand horticulture industry welcomed the Environmental Protection Authority’s (EPA) decision allowing the release of a tiny Samurai Wasp into New Zealand, if ever there was an incursion of the BMSB. Read the media release here.

KVH and Zespri have recently designed a useful infographic tool for growers. It encourages growers to cast their eye into a possible future where BMSB has arrived in New Zealand and all response/eradication efforts have failed. What long-term management of the bug might look like on-orchard; factors to consider into future planning; and the times of the year each is most appropriate, is summarised in the infographic here.

Are you a quizmaster like our young growers?

Annual Young Grower competitions have been taking place throughout the regions over the last few weeks and we’ve had biosecurity rounds included in many of them. Congratulations to everyone who took part – it’s great to see such knowledge and enthusiasm for the importance of biosecurity. Just yesterday at the Bay of Plenty Young Grower event we provided an interactive quiz to each of the competitors, who impressed us with their on-orchard biosecurity expertise. Congratulations to Jack Canham from Apata for winning the biosecurity section on the day. How do you compare to this year’s young growers? Think you’d outdo them? Test yourself on the Connections game here (where you will need to group words that have a common thread, into four groups of four) before seeing the set of quiz questions we asked competitors here. Answers for the quiz questions can be found here. Good luck!

Mature plant movements

Winter is the time when growers look to replace plants on their orchards or plant new blocks. This article is a reminder that if these plants are being moved between properties there are biosecurity requirements that must be met to reduce the likelihood of spreading pests and diseases, including Psa. These requirements also provide the best chance of a successful response if a new organism was detected in our industry. While most kiwifruit plant movements come from nurseries, growers may occasionally move mature plants between orchards. The movement of any plants are a risk pathway, and it is important for growers to understand what’s required under the Pathway Plan, as outlined below. What does this mean for you? If you are taking mature plants from your own orchard for use on that same orchard there are no requirements under the Pathway Plan. If you are moving orchard plants from your orchard to another orchard, or source orchard plants from someone else, you need to ensure that you are meeting the requirements of the Pathway Plan – by being Kiwifruit Plant Certification Scheme (KPCS) certified for example. If you are a Psa non-detected supplier, you will need to complete a Psa test. It isn’t onerous to become certified as an orchard plant supplier and there are no costs (unless diagnostic testing is required). The new Pathway Plan requirements are very similar to existing protocols. They do require planning in advance to ensure monitoring can occur while vines have leaves and are in active growth. More information about orchard plant movement information, including the KPCS manual and supporting documents, is available here.

Upcoming AGM and voting packs

A reminder that our Annual General Meeting (AGM) is coming up and growers will receive their AGM packs by email at the end of this month. This is a public meeting and anyone who is interested is welcome to attend. Special guest Dr Jacqueline Rowarth will be joining us to speak about precision breeding, followed by the NZKGI and then Zespri annual meetings.
