Faba bean (Vicia faba L.) is one of the major pulse crops grown in the highlands of Ethiopia buttheir yields are reduced by chocolate spot disease problem. This study was conducted at Simada district in 2021 cropping season with the objectivesto assess the distribution of chocolate spot and develop Integrated Disease Management using host resistance and fungicide.A survey was conducted in the five major faba bean producing areas of at Simada district. A total of 75 faba bean farmer fields were assessed for the incidence and severity of chocolate spot disease. Thefield experiment was arranged in randomized complete block design in 3x4 factorial combinations with three replications. The treatmentswere three faba bean varieties (Local, Dosha and Huchallu ) with four fungicide spraying frequency including: . (un spray,1 times spray, 2 times spray and 3 times spray) of Mancozeb 80% WP at 2.5kg/ha . Relatively high mean incidence (98.9%) and severity (59.2 %) was recorded at Dubdubia kebele administration and low disease incidence (56.8%) and severity (30%) was recorded at Arega kebele administration. The experiment was conducted under rain fed condition at Bazera meda Kebele administration in Simada district on farmer’s field. The interaction of variety with fungicide spraying frequency had significant effect on chocolate spot disease management. The minimum disease severity (25.67%) recorded from Dosha with three times spraying frquencey while the maximum disease severity (55.2.%) was recorded from unsprayed local variety at the last day of assessment . In this stud the Dosha faba bean variety with three times spraying frequency was the highest yield and local unsprayed was the least yield. Therefore, it is concluded that Dosha variety interacting with three times fungicide spray frequency is best in the study area.
