Overview of Epidemiology, Biology and Integrated Management of Chocolate Spot ( Botrytis fabae) of Faba Bean in Ethiopia

Abstract

Chocolate spot is a serious disease that cause yield reduction on Faba bean crop, thus, effective management is essential. The objective of this review work was to review available to manage chocolate spot of faba bean with host resistance and fungicides. There are many biotic and abiotic factors which hampers Faba bean production in Ethiopia. From biotic factors chocolate spot (Botrytis fabae Sard.) is the major fungal disease hampering Faba bean production in Ethiopia.). It is a highly prevalent and destructive disease, causing yield loss up to 61% on a susceptible and 34% on tolerant Faba bean genotypes in the central highlands. But we can manage this economically important disease in manner which comprised by using different methods from these late sowing of Faba bean, mixed cropping of Faba bean with cereal crops, fungicides application and crop rotation were found better to reduce the disease and increased the grain yield. Therefore, use all available diseases management methods in combination that is IDM (Integrated Disease management) is better to reduce disease severity of chocolate spot.
