Abstract— Barley (Hordeum vulgare L.) is one of the ancient grain crops cultivated and used worldwide. In Ethiopia, barley is among important staple crops next to tef, maize, wheat and sorghum mainly grown on about 1 million ha of land with average yield of 2.1t ha. Leaf scald is one of the most important diseases of barley in the worldwide where the crop is grown and it causes significant reduction in yield and quality. In Ethiopia, barley is the predominant cereal in the high altitudes and it accounts nearly 25% of the total production in Africa. In addition, Ethiopia is the second largest barley producer in Africa.
Leaf scald is one of the most important diseases of barley in the worldwide wherever the crop is grown and it causes significant reduction in yield and quality. Yield loss due to scald disease reaches up to 100% in susceptible cultivars under severe epidemics. In Ethiopia, scald is among widely distributed and destructive diseases in cool highland areas and yield losses reaching about 67% have been recorded. This review discusses recent information on economic importance, epidemiology, life cycle, geographical distribution and disease management of barley leaf scald disease. It also presents the barley leaf scald disease management methods such as cultural, chemical, use of host resistance methods as well as integrated barley leaf scald disease management. Under host resistance method, information on types of resistance, sources of resistance have been presented.
Keywords— Barley, Scald disease, Management, Methods, Cultural, Chemical, Host resistance.
