Abstract

Mungbean yellow mosaic virus disease is the most devastating disease of mungbean world widely causing qualitative and quantitative losses in yield upto cent percent. Information regarding disease severity and vector population may help in planning of better management strategies. Therefore, a roving survey was conducted to know the incidence of MYMV and its vector Bemisia tabaci in southern Karnataka during Rabi summer 2016-17 and 2017-18. Among the thirty villages, the percent disease incidence ranged from 27.00-87.80 and 30.25-95.58 in respective years. The highest percent disease incidence of 79.81 and 83.73 was recorded in Chamarajanagar district in 2016-17 and subsequent year respectively, followed by Tumakuru (52.89% and 48.21%) and Bengaluru urban (43.00% and 45.34%). While, the lowest incidence was recorded in Bengaluru rural (29.38% and 33.65 %) followed by Mandya (37.05% and 41.96%). The average whitefly population ranged from 2.3-4.5 and 2.7-5.2 per plant in Rabi summer 2016
