On Thursday 29 October, a panel-style webinar presented by the Australian Wine Research Institute and the Yarra Valley Wine Growers Association will cover a range of topics related to vineyard viruses, in both Australia and New Zealand, as well as the experiences of Yarra Valley growers when considering replanting vineyards.
With the difference in time zones, this means the webinar will be held at 11:00 pm. However, if you’re not a night owl, the webinar recording will be available on the AWRI YouTube channel to anyone who registers.
Dr. Fiona Constable will present an overview of viruses and virus-like diseases with tips for their management. Dr. Vaughn Bell will present the New Zealand perspective with a focus on insect transmission of grapevine leafroll diseases. Rob Sutherland will cover issues encountered in Yarra Valley when replanting vineyards that have remnant virus-positive rootstock or vines. It is important to note that the mealybug species present in Australia and New Zealand are different than the one here in Ontario in that their mealybugs move down to the roots while ours stays above-ground so does not stay in the root remnants. Please take this into account when watching the Sutherland presentation.
