 Fusarium graminearum (Fg) is a serious fungal disease of cereal grains that affects yield and grade, resulting in poor quality grain intended for feed, malting, milling, and the biofuel industry. Recent surveys indicate Fg is established in southern Alberta and traces are present in central and northern regions of the province. Although all cereal crops are susceptible, durum and corn are major hosts.
Fg can be effectively controlled under normal conditions using a combination of disease prevention strategies throughout the growing season. The use of a single strategy usually fails when weather conditions are favourable for infection. During the growing season, strategies include careful herbicide applications, irrigation management and an in-crop fungicide application if risk levels are moderate to high.
