Actigard - recommended timings
21 September 2017

Actigard™ is an important product for Psa management and should be incorporated into spring spray programmes alongside copper, to help protect new growth which is highly susceptible to Psa infection.

Actigard™ has systemic activity, and activates the plants natural defence systems within four to seven days of application. The active ingredient acidbenzolar-S-methyl is taken up rapidly, making the product effectively “rain proof” one hour after spraying. It moves both upwards and outwards into new growth and downwards to lower leaves and roots.

Trials have shown Actigard™ reduces leaf spot and flower bud infection and should be considered, particularly in areas where early signs of Psa infection have been found.

For mature vines, time first applications after leaves have reached 25mm in diameter, and for newly grafted vines (Gold3) begin applying Actigard™ once grafts are around 25cm long. Delay application if vines are under stress and ensure full label rates (20g/100L) are used. Repeat applications can be made 21 days later.  A second key application timing for Actigard™ is one to seven days prior to flowering, when other options for Psa control are limited and infection risk remains high. A maximum of four applications per season applies.

Holographic fruit fly
21 September 2017

New hologram technology is being used to educate international travellers about the importance of biosecurity.

The prototype hologram greets visitors at Auckland International Airport by giving them a 3D display of biosecurity risk items and explains why we don’t want them in New Zealand.

The display has been initiated by the Ministry for Primary Industries (MPI) and will show prohibited items, initially focussing on fruit carried inside luggage. It then follows a hitchhiking fruit fly and the potential damage that it could do to an orchard and the fruit industry. Mounted atop a purpose-built unit, the display doubles as a bin where visitors can ditch any biosecurity hazards they might still have on them.

Fruit fly readiness planning
21 September 2017

Readiness and response activities for the Brown Marmorated Stink Bug (BMSB) have been a focus of many articles in The Bulletin lately, but there is also plenty of similar readiness work underway for other organisms, both within the kiwifruit industry and at a national level.

Fruit fly in particular remains a high priority given the market access implications that can result from incursions of this pest.


While we are relatively well prepared for fruit fly with a tried and tested response plan, and a surveillance grid of around 8,000 pheromone traps checked on a fortnightly basis, incursions can still be costly to our industry as a result of market access restrictions. Horticultural sectors and the Ministry for Primary Industries (MPI) are working together on a shared work programme under Government Industry Agreements (GIA) to improve our readiness and reduce the impact of any future fruit fly incursion. Projects are cost shared and delivered under the Fruit Fly Council and Technical Working Group, which KVH is represented on.

As September marks the beginning of the high-risk season for fruit fly incursions, MPI is also beginning their summer campaign to reduce the likelihood of incursions. One initiative underway is the use of new hologram technology at Auckland International Airport to educate travellers about the damage a hitchhiking fruit fly could do to New Zealand orchards.

Growers must not be afraid to report suspect finds
21 September 2017

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. Remember, there are no likely market access implications from Brown Marmorated Stink Bug (BMSB) but the production impact is vast.

The sooner you alert us, the more we can do to help you. Early detection is key to eradiction – 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.

Improved import requirements help manage BMSB risk
7 September 2017

KVH continues to advocate strongly on behalf of the industry for strict and appropriate biosecurity border controls, and we’re pleased with the recent announcement from the Ministry for Primary Industries (MPI) of amendments to requirements for the import of vehicles, machinery and other equipment including tyres, from Italy.

During the 2016/2017 risk period, MPI recorded 152 Brown Marmorated Stink Bug (BMSB) interception events associated with finds of both dead and live BMSB on new and used items. MPI inspectors were unable to differentiate between those insects that may have been dead or live on reaching the New Zealand border as fumigation was also conducted immediately after arrival and would have killed any live specimens.

Italy was found to be the origin of 57% of these interception events, and of the 17 BMSB aggregations (larger groups of insects) that were found, 13 (76%) were of Italian origin. MPI are also aware that in areas with high BMSB populations, vehicles and machinery that are manufactured or stored there are highly infested. For example, one vehicle brand of Italian origin was found to be 50% infested with BMSB at the port of export.

To manage the significant risk of BMSB infestation in these items, the Import Health Standard – which specifies the requirements that must be met to manage biosecurity risk associated with importing goods and getting biosecurity clearance for them – has been modified to include more targeted measures around fumigation and making sure that MPI approved management systems are used.

The new requirements apply for the duration of the high-risk season of September 2017 through to April 2018. MPI has signalled that it intends to further revise the standard, in consultation with importers and exporters, before the end of April 2018 to ensure potential BMSB risk continues to be well managed. KVH will also be involved in this process.

World expert helps the kiwifruit industry prepare for BMSB
7 September 2017

Last week KVH and Zespri hosted two international Brown Marmorated Stink Bug (BMSB) experts, Dr Tracy Leskey and Dr Kim Hoelmer, to refine our approach for managing this pest should it manage to establish in New Zealand.

They attended a meeting with the Ministry for Primary Industries (MPI) and other horticultural sectors where they provided input into our national response plan for BMSB, including how we would respond to an initial detection, and attempts at eradication.

Dr Leskey also presented to kiwifruit growers early in the week. The entomologist and researcher for the United States Department of Agriculture (USDA) discussed BMSB with more than 100 people who packed into The Orchard Church in Te Puke to learn more about the unwanted pests impacts on horticulture, post-harvest facilities, and residential areas in the USA.

Dr Leskey went into detail about actions underway in the USA to manage BMSB in crops; the importance of collecting good dispersal and behavioural information about the bug; effective insecticides; biological control options; and various border strategies such as traps and trap crops like sorghum and sunflower.

As a coordinator of StopBMSB – one of the world’s largest research initiatives into BMSB, involving more than 50 researchers across 18 organisations – Dr Leskey will continue to work with KVH and Zespri to fill knowledge gaps around our New Zealand eradication plans, as well as potential long term management and control options within kiwifruit orchards.

Much of what Dr Leskey discussed is mentioned in the StopBMSB integrated pest management fact sheet available online, which provides a synopsis of what researchers have learned so far, and management recommendations using an integrated approach.

Growers at the meeting watched a new video demonstrating the impacts BMSB has had on gold kiwifruit in Italy – you can view it on the KVH YouTube channel here.

KVH detailed the work being done to ensure the New Zealand kiwifruit industry is prepared for BMSB, including a promising control strategy in the form of a biological control (the Samurai Wasp), in the latest KVH Annual Report. More information about response and long term management plans should the bug establish in New Zealand, is also available on the BMSB page of the KVH website.

Spring brings Psa symptoms
7 September 2017

As spring sap starts to flow and vines come out of winter dormancy, Psa symptoms will become more visible.

Spring is a high-risk season for Psa, and growers, particularly those on early sites, are recommended to start monitoring their vines to understand how Psa is unfolding on their orchards.

Focus on high-risk plants/areas, paying particular attention to areas where application of a full Psa spray programme has been compromised due to difficult or impossible ground conditions through the autumn and winter period.

Be sure to remove infected material promptly to reduce the risk of Psa spread.

Throughout spring, growers should focus on minimising leaf spot and flower bud infection and maintain copper cover, including Actiguard™ and consider CPPU products.

Reports from the Bay of Plenty, Franklin and Gisborne regions over the past fortnight indicate some Gold3 growers are seeing active cankers with incidence more widespread than last year. More symptoms have been reported for M91 males.  Some Waihi, Waikato, Whanganui and Hawkes Bay growers report symptoms extending across both male and female Gold3 vines.

Click here for a photo gallery of symptoms recently reported to KVH.

A reminder, growers can use the Psa-V Risk Model to help identify upcoming risk periods and to assist with the timing of protective sprays. Click here to register to use the model if you haven’t already.

The new Psa-V Seasonal Management Wall Chart 2017-18 is also a handy reference tool and is included in your latest Zespri Kiwiflier. It is also available to view or download from the KVH website. A key feature of the chart is the KVH Recommended Product List, which sets out the approved products for protection against Psa-V, their year-round application rates, and permitted use periods.

Spreading the stink bug message
7 September 2017

KVH is involved in several initiatives to improve awareness and readiness for the Brown Marmorated Stink Bug (BMSB). The nationwide effort to keep this pest out continues as we enter the high-risk period and work with the Ministry for Primary Industries (MPI) and other groups across horticulture to update our comprehensive communications strategy.

KVH is co-funding the strategy which is aimed at lifting public awareness around the damaging impacts of BMSB and will hopefully increase the livelihood of early detection through passive surveillance.

Key aspects of the communications strategy include:

Video
•    KVH has extra videos available online (and these will be used at various presentations too) relating to the impacts of BMSB on kiwifruit in Italy, a shortened Bug Man video about catching BMSB, and a One News article about the impacts all kiwis will face if this bug gets here and establishes.
•    MPI and industry groups are developing videos with BMSB champions.

Print advertising
•    Full page advertising over the high-risk period in NZ Gardener, Go Gardening, Kiwi Gardener, NZ Grower, and various industry publications and newsletters like The Kiwifruit Journal and The Orchardist.

Digital advertising
•    30 second ads running on the TVNZ and Three Now on demand services, and YouTube.
•    Displays on the Stuff, Herald, TVNZ and Three websites.

Media
•    Interviews and stories with mainstream media outlets using industry spokespeople as champions, and continuing the relationship with the Bug Man.

Social media
•    Facebook, Twitter and YouTube banners and ads pushing messages from the Bug Man and encouraging travellers/visitors to check their bags, rooms, and mail parcels.

Screens
•    Digital advertising on screens at Auckland, Wellington, Christchurch, Dunedin and Queenstown airports.

Posters, stickers, and collateral
•    More engagement with everyone from garden centres and transitional facilities to backpackers, motels and travel agencies about BMSB and distribution of posters, stickers, fridge magnets and fact sheets.

A new video is available showing the impacts of Brown Marmorated Stink Bug (BMSB) on gold 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 this pest can do. BMSB is on the Kiwifruit's Most Unwanted list and a strong focus of KVH, especially with the high-risk season upon us.

Being on the lookout, knowing what to look for and how to report the bug is key - email KVH if you, your family or friends would like more of our handy fridge magnets to help identify this pest.

The video was shown at the BMSB grower meeting with international expert Dr Tracey Leskey, early last week. Read more about the meeting and industry preparedness for BMSB here.

Be on the lookout for new thrips in glasshouses
7 September 2017

Poinsettia thrips are an emerging pest of greenhouse nursery plants in eastern USA and in some parts of Asia. 

The Ministry for Primary Industries (MPI) is looking into the discovery of a small number of thrips on contained nursery plants, including kiwifruit plants, in New Zealand. A fact sheet that has been developed with KVH is available here.

If the pests were to establish in New Zealand they won’t survive outside of greenhouses but will cause significant challenges to the glasshouse industry.

Growers, nursery and greenhouse staff in particular are asked to familiarise themselves with the fact sheet and immediately report any signs of the pest to the MPI exotic pest and disease hotline on 0800 80 99 66.

Sniffer dog joins stink bug fight
7 September 2017

A bug-sniffing detector dog introduced by the Ministry for Primary Industries (MPI) will help stop the potentially devastating Brown Marmorated Stink Bug (BMSB) from making a home in New Zealand.

The labrador, named Georgie, demonstrated her sniffing skills on stage last week by locating dead stink bugs hidden in a harvesting machine at the New Zealand Winegrowers conference.

MPI will have two trained dogs ready to sniff out stink bugs this summer, including a specialist dog to assist with detecting the pest in the event of an incursion. Read more here.

Be on the lookout for myrtle rust
7 September 2017

Now it’s spring, myrtle rust may be more noticeable. If you see it, don’t touch it – call the Ministry for Primary Industries (MPI) on 0800 80 99 66.

Myrtle rust could affect iconic New Zealand plants like pōhutukawa, kānuka, manuka, ramarama and rātā, as well as species such as eucalyptus, guava and feijoa.

To protect any myrtaceae species on your property (eg in your garden or orchard), you may want to consider spraying them with copper at label rates.

Be on the lookout 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) which can appear on older lesions
•    buckled or twisted leaves which may die off.

*Update 13 September 2017:

The Ministry for Primary Industries (MPI) has issued an update advising that since myrtle rust was found in New Zealand earlier this year, there has not been a single feijoa plant found with the infection.

MPI has taken samples from feijoa plants in nurseries and home gardens where other plants are infected with the disease and the feijoa plants were clear. This information, combined with Australian data showing feijoas appear to be resistant, has led to MPI concluding that feijoas present a low risk of spreading myrtle rust to other uninfected myrtle plants.
