Research identifies growing fungicide resistance

Fungicide resistance across Australian vineyards is on the rise, with new research identifying higher–than–expected populations of powdery mildew, downy mildew and botrytis bunch rot with resistance. Powdery mildew, downy mildew and botrytis bunch rot are the three most economically significant diseases in Australian viticulture – costing the sector in lost crops and disease management.
