Winegrape powdery mildew app goes global

Grape growers and winemakers around the world will be able to easily assess powdery mildew in the field with the help of a mobile application just released globally. PMapp, which supports decisions about grape quality, has been developed by the University of Adelaide in close collaboration with the Australian grape and wine sector, and supported by Wine Australia. “Powdery mildew is a serious disease that affects grapevines worldwide and can cause off flavours and aromas in wine if it is not controlled,” says project leader Eileen Scott, Professor of Plant Pathology at the University of Adelaide’s School of Agriculture, Food and Wine.
