Mungbean is one of the most important pulse crops for protein supplement in subtropical zones of the world. Looking the productivity of mungbean in India, there are several production constraints in the mungbean growing areas among which diseases and pests plays a prominent role. Bean common mosaic Virus (BCMV) is a most destructive disease and one of the earliest seed borne, which belongs to the Potyvirus group. The group constitutes the largest group having large number of plant viruses which cause heavy yield losses in crops. Symptoms of downward leaf rolling, thickening of leaves, mosaic, leaf deformation, necrosis of tissues of abaxial side of leaves, necrosis of apical stem portion, etc. It is seed borne disease and can be transmitted in the non-persistent manner by several aphid species. Bean common mosaic virus has a wide host range.BCMV as flexuous particles of 823 nm long in mungbean capsid protein of 34 KDa and predicted ~1300 bp product. The virus was found to survive in seed coat, cotyledons and embryo as well as in pollen. The relative humidity, bright sun shine, rainfall positively, vapour pressure correlated with per cent disease intensity of BCMV. The information regarding the symptoms, host, transmissions, location of virus, ELISA, RT-PCR, SDS-PAGE, Epidemiology and management of BCMV disease has been reviewed in this article.
