Of all pulse crops grown in Ethiopia, faba beans stand 2nd after common beans and before chickpeas which are all considered to be the top export crops accounting 90% by volume and 85% total earnings. However, diseases such as chocolate spot, root rot and rust are the major biotic constraints affecting yield wherever the crop grows. Yield losses of up to 61% on susceptible cultivars and 30-50% under favorable conditions for chocolate spot were reported. Root rot was also recognized to cause complete crop loss during severe infections and yield loss may reach 100% in susceptible cultivars.
