Cercospora leaf spot caused by Cercospora canescens Ellis & Martin is one of the most important diseases of mungbean. The cercospora leaf spot appears every year in varying intensity and cause heavy losses in yield. Field experiment conducted during 2009 and 2010 cropping seasons to evaluate the effect of different management options viz., carbedazim, neem leaf extract, intercropping with seasmum and their integration in integrated disease management. Minimum disease intensity (11.26%), maximum disease control (77.63 %) and grain yield (9.70 q ha1) were observed with spraying of carbendazim + spray of neem (leaf) extract + inter-cropping of seasmum (2:1). Maximum increases yield (34.74 %) was recorded in this treatment as compared to check having maximum disease intensity (50.33 %) with lowest yield (6.33 q ha ̈1).
