Ergot: A new disease threat to sorghum in the Americas and Australia
Plant Disease 82 (4), 356-367
Abstract: Sorghum ergot, caused by Claviceps sorghi, is a serious disease that affects the sorghum, Sorghum bicolor production of F1 hybrid seed. Ergot is particularly severe in male-sterile lines when either nonsynchronous flowering of A-line and restorer lines or adverse environmental conditions result in a lack of viable pollen and delayed seed set. In India, losses of 10 to 80% have been reported in hybrid seed production fields. The sudden, widespread appearance of ergot in both Brazil and Australia, and eventually throughout the Americas in recent years, demonstrates the potential impact of C. africana on the sorghum industry worldwide. The article reviews the biology and epidemiology of the disease, as well as current management options.
