The study determined the effects of different doses of Co-60 gamma radiation on the virulence of Cercospora cruenta Sacc. which causes cercospora leaf spot disease on mungbean. The causal organism of Cercospora leaf spot disease, Cercospora cruenta Sacc. was exposed to gamma radiation from Cobalt-60 at doses of 40, 80 and 120 Kr and inoculated to seedlings of MG50-10A variety of mungbean. Based on the degree of infection observed on the plants, the study indicated that the doses of gamma radiation used caused a very minimal reproduction of new races with increased and decreased virulence.
