Abstract

Blackgram (Vigna mungo L.) is a vital pulse crop valued for its high protein content and role in sustainable agriculture. However, its productivity is severely affected by yellow mosaic disease (YMD), primarily caused by Mungbean yellow mosaic virus (MYMV) and Mungbean yellow mosaic India virus (MYMIV), both transmitted by vector whitefly (Bemisia tabaci). To evaluate the efficacy of chemical insecticides in managing YMD through vector control, a field experiment was conducted during the rabi 2024-25 at the Main Agricultural Research Station (MARS), Raichur, India. Among the tested treatments, seed treatment with imidacloprid 600 FS followed by two foliar sprays of flonicamide 50 WG at 0.03 per cent concentration at 20 and 35 days after sowing proved most effective. This combination resulted in the lowest whitefly population (2.6 per plant; 72.02 % reduction over control), minimal disease incidence (30.08 %; 48.99 % reduction over control) and the highest grain yield of 10.2 q/ha (5.43 q/ha improvement over control). The results demonstrate that integrated chemical management significantly reduces YMD impact and enhances black gram productivity under field conditions.
