Abstract
Field trials were carried out during 2018-2019 and 2019-2020 autumn seasons to study the role of barrier and intercrops against whitefly - borne Mungbean yellow mosaic virus (MYMV) disease. In the treatment (T2) two rows of Maize sown after 15 rows of Mungbean, the lowest mean population of whitefly 7.03 per plant was recorded which was followed by 7.42 whitefly per plant in the treatment (T4) with two rows of Sorghum after 15 rows of Mungbean. In barrier crops, the lowest disease incidence of 28.94% was recorded in the treatment (T2), two rows of maize after 15 rows of Mungbean. The mean seed yield recorded was 6.75 q/ha. The treatment (T2), two rows of Maize after 15 rows of Mungbean was recorded to be effective in the management of MYMV disease. The lowest mean whitefly population of 4.71 per plant was recorded in the above treatment, Mungbean sown with Maize in 4:2 ratio. Mungbean sown with Maize in 4:2 ratio was recorded to be efficacious in the management of MYMV disease. The results indicated that the barrier crop of maize interfered with the movement of vector whiteflies.
