GWRDC boosts spray application knowledge in Aussie wine regions – Media release

An impressive majority of Australian winegrape growers will improve their vineyard spray application practices following their participation in the Grape and Wine Research and Development Corporation’s (GWRDC) 15 recent Spray Application: Doing it Better workshops across the country.

Of the 480 attendees nationwide, 88 per cent confirmed they will make changes to the techniques they currently use for spray application in the vineyard.

The success of the workshop series was further demonstrated by 98 percent of attendees agreeing the workshop met their overall expectations.

The workshops, led by international speakers Dr Andrew Landers from Cornell University, USA, and Dr David Manktelow from FreshLearn, New Zealand, shed light on current research in spray technology across the county’s mainland states.

A highlight of the workshops, the practical vineyard spray demonstration component, focused on the importance of effective spray set-up, use of tracers for sprayer assessment and using new technologies to improve deposition and on-target application.

Speakers stressed the three factors the spray operator should keep top of mind – air flow direction, volume of air and the speed of the air.

According to GWRDC Executive Director Stuart Thomson, ‘the workshop series demonstrates GWRDC’s commitment to connecting current research to real-life practice’.

‘Effective spray application is vital for pest and disease management. GWRDC is pleased to have successfully coordinated the delivery of information on new technologies to industry that results in environmental and economic improvements’, he said.

A series of short videos will be made available in the coming weeks to those who could not attend. The first video, Principles of spray Application is available here.

GWRDC invests in and directs research, development and extension (RD&E) along the whole value chain ‘from vine to glass’ to support a competitive Australian wine sector.

We collaborate with key stakeholders to coordinate and direct investments to best address the sector’s RD&E priorities. GWRDC is funded by levies paid by grapegrowers and winemakers and the Australian Government, that provides matching funds.
