As in all viticultural regions in Australia, grape growers in Tasmania apply fungicides repeatedly to protect vines from powdery mildew caused by Erysiphe necator (syn. Uncinula necator). Tasmania has never had a mildew management strategy developed specifically for local conditions. Growers have tried to modify recommendations applied elsewhere but poor spray timing and coverage still lead to control failures in some vineyards each growing season.
