Fusarium head blight (FHB) or head scab of wheat can cause significant yield loss, and damaged grain is often contaminated with the mycotoxin deoxynivalenol (DON), commonly known as vomitoxin. The disease is best managed through a combination of variety resistance and timely applications of fungicides when weather conditions elevate the risk of disease development. In recent years, there has been considerable effort to predict the risk of FHB and the need for fungicide applications in wheat.
