All go for Aureo Gold
29 November 2018

New Psa product Aureo Gold is now registered for use on kiwifruit and has BioGro certification.

Limited stock of Aureo Gold was available for 2018 and growers are advised to check with their nearest retailer to determine future availability.

Just approved by the Agricultural Compounds and Veterinary Medicines Group (ACVM), Aureo Gold was discovered and isolated from an Otago apricot by Plant & Food Research scientists and since then extensive field trials have demonstrated its protectant efficacy.  Research suggests this product has multiple modes of action, including: 

·         physical disruption of Psa cells on leaf surfaces that appears to affect the ability of Psa to colonise stomata,

·         acting as an elicitor activating kiwifruit host defence genes, allowing the plant to react more quickly and to a higher degree to the presence of Psa. 

Research to date also indicates that Aureo Gold doesn't produce anti-microbial compounds, and therefore resistance development is unlikely.

In trials on Hayward vines, Aureo Gold gave similar levels of protection from leaf spotting as Kocide Opti in the 2017/18 season.  The image above shows Aureo Gold's protectant ability in potted plant trials. The leaf sprayed with water on the left, and a leaf sprayed with Aureo Gold on the right were then inoculated with Psa, with resultant reduction in leaf spotting symptoms.

Aureo Gold can be applied from budbreak to six weeks after flowering, at seven to 14-day intervals whenever Psa protection is required. It’s use period for this season is closing (this and its short shelf life means there is limited stock at the moment) but trials have indicated good crop safety when applied throughout the flowering and fruitset period.

How to use Aureo Gold:

·         Good coverage is critical and the use of an adjuvant such as DuWettt or DriftStop is recommended. 

·         Apply at 50g/100L of water, in 600-1000L/ha. 

·         Don't apply more than 4.5kg active ingredient per hectare, with a maximum of 10 applications per hectare per season. 

·         Check the label for compatibility information – don’t use in a mixture with copper.  

Limited stock of Aureo Gold was available for 2018 and growers are advised to check with their nearest retailer to determine future availability. Aureo Gold will be available for order through Farmlands, Fruitfed Supplies and Horticentre. It comes in a 1kg pack and has a shelf life of 4 months when stored in a cool dry place below 25 degrees Celsius. 

For more information see the Arysta Aureo Gold technote or contact KVH on 0800 665 825 to speak to the team. Refer to the KVH recommended product list for more information about products and summer rates.

If you missed out on the Kiwifruit Biosecurity Grower Day during Biosecurity Week and want to watch the presenters in action, you can view videos from the day now on the Zespri Canopy.

More than 120 people attended the day covering readiness activities; research into soil borne diseases and the importance of traceability; BMSB preparedness; a fruit fly incursion market access simulation; and a presentation on the new Ko Tatou This Is Us national advertising campaign.

Also, look out for more information and images from Biosecurity Week in your next Kiwiflier and Kiwifruit Journal.

Building biosecurity capability through education
1 November 2018

KVH attended a pilot programme in the Hawkes Bay this week to help test and provide feedback on a recently developed New Zealand Qualifications Authority (NZQA) micro-credential on biosecurity.

Micro-credentials, also known as badges, nanocredentials and nano-degrees, recognise the achievement of a defined set of skills and knowledge. Learning undertaken is validated in a micro-credential and is important in itself (not simply as a stepping stone to any subsequent qualification).

This biosecurity micro-credential was developed under the NZQA framework (Level 5) by the Primary Industry Training Organisation (ITO) and Horticulture NZ, with input from biosecurity managers from KVH, Summerfruit New Zealand, New Zealand Apples & Pears, New Zealand Winegrowers, TomatoesNZ and Vegetables New Zealand.


The focused course is designed to enhance industry biosecurity capability, and targets grower owner-operators and supervisors/managers. Content builds an understanding of biosecurity and provides a framework to identify, prioritise, and manage biosecurity risks on orchards and farms.

A second test pilot was held in Nelson with two kiwifruit industry representatives attending. Feedback to the organisers will ensure the course is relevant to industry.

Tauranga pioneers’ new approach to biosecurity threats, could be implemented nationwide: Iwi, businesses, and local and central government have come together through the Tauranga Moana Biosecurity Capital programme to help educate the public on biosecurity risks on our own doorsteps.

BMSB threat to Bay's billion-dollar kiwifruit industry: A 260% increase in the number of Brown Marmorated Stink Bugs (BMSB) found at New Zealand's borders has heightened a billion-dollar risk to the Bay of Plenty economy. In Italy the bugs have been found to cause up to 40% drop in kiwifruit prior to harvest.

Biosecurity Award finalists reflect huge national effort in biosecurity: KVH is honoured to represent kiwifruit as a finalist in the industry category at the New Zealand Biosecurity Awards. The awards were established two years ago to recognise and celebrate exemplary contributions to protecting our taonga (precious natural resources) and ensuring New Zealand's biosecurity system remains resilient, effective, and world-leading.

Consultation closing on Pathway
1 November 2018

KVH is consulting on a proposed pathway for growers in Exclusion and Containment regions to access kiwifruit plant material from Recovery regions, with negligible increase in risk.

The proposed pathway is based on tissue culture and rather than relying on a single measure to mitigate risk, the pathway contains several different measures over a 14-month period to reduce risk to an acceptable level. The pathway adopts relevant measures from the Actinidia Import Health Standard which allows tissue culture kiwifruit plants to be imported into New Zealand and includes the peptone screening protocol that allows for screening of low levels of Psa in tissue culture plants.

Details of the proposed pathway are available on the KVH website, including:
- A summary presentation given to South Island and Whangarei growers last month
- An independent review of the pathway by Scion Research concluding that this pathway would result in negligible increase of risk in introducing Psa to these regions.


If you would like more details, please contact KVH and a complete version of the pathway standard will be provided on request.

The consultation period closes 5pm tomorrow, Friday 2 November 2018. To provide feedback on the proposal please email info@kvh.org.nz or phone KVH on 0800 665 825.
