Mungbean Yellow Mosaic Virus (MYMV) disease is one of the most serious diseases of green gram Vigna radiata (L.) in India. In nature, this disease is spread through the whitefly vector, Bemisia tabaci Genn. This research paper reports the result of field trials on management of the MYMV disease by Cultural, Chemical and Biological methods. Integration of seed treatment with insecticides imidacloprid 17.8 SL @ 3ml/kg and foliar spray of imidacloprid 17.8 SL @ 0.5/lit sprayed on 25 DAS and 40 DAS respectively, recorded highest plant height (76.33%) during 2018 and (78.45%) during 2019 and higher grain yield (9.05q /ha) and the lowest incidence of MYMV (17.90%) diseases and whitefly populations (18.13/ plant on 20 DAS, 2.44/ plant on 30 DAS, and 2.97/plant on 45 DAS. It was found to be the best with regards to no. of pods/plants 22.51 during 2018 & 23.72 during 2019, pod length 9.45 during 2018 and 9.73 during 2019 and no. of seeds per pod 11.11 during 2018 & 12.24 during 2019. The subsequent efficacious treatment was integration of seed treatment with insecticide based chemical compound, Spinosad and foliar sprays of spinosad sprayed on 25 DAS and 40 DAS provided plant height (72.45%) during 2018 & (74.12%) during 2019, no. of pods/plants 21.23 during 2018 & 21.67 during 2019, pod length 9.07 during 2018 & 9.57 during 2019, no. of seeds per pod 10.44 during 2018 & 11.31 during 2019 and grain yield (8.59 q/ha) with the disease incidence of MYMV (19.60%) and whitefly populations (20.94/plant on 20 DAS, 2.47/plant on 30 DAS, and 3.40/plant on 45 DAS, followed by integration of seed treatment with the insecticide, Dimethoate (ml/kg) and foliar sprays of Dimethoate (1.5 ml/lit) (T3) sprayed on 25 DAS and 40 DAS provided plant height (70.85%) during 2018 & (72.67%) during 2019, no. of pods/plants 19.33 during 2018 & 20.33 during 2019, pod length 8.44 during 2018 & 8.84 during 2019, no. of seeds per pod 9.55 during 2018 & 10.61 during 2019 and grain yield (8.65 q/ha) with the disease incidence of MYMV (20.27%) and whitefly populations (20.04)/plant on 20 DAS, 2.52/ plant on 30 DAS, and 3.25/plant on 45 DAS.
