This project will investigate the effectiveness of existing and emerging wheat powdery mildew (WPM) control options across a range of varieties with diverse susceptibility ratings for growers and agronomists affected by powdery mildew in SA. It will investigate the agronomic efficacy and economic effectiveness of control options in each wheat variety to create new information on emerging powdery mildew. The project will also extend existing knowledge from current WPM SAGIT projects and newly generated findings to growers.
