Abstract: Yellow mosaic virus disease of Black gram [Vigna mungo (Linn.) Hepper] caused by mung bean yellow mosaic Gemini virus and transmitted by whitefly (Bemisia tabaci Genn.) is most serious in northern states of India, particularly, Bundelkhand Zone of Madhya Pradesh. Efficacy of some indigenous neem products, insecticides and their admixtures were tested at Research Farm of College of Agriculture, Tikamgarh during kharif 2003-2005. The results indicated that admixture treatments, neen seed kernel extract (NSKE ) (in cow urine), 3% + dimethoate, 0.03% and neem oil, 0.5% + dimethoate, 0.03% not only reduced the incidence of whitefly and yellow mosaic but also of pod borer. These treatments gave maximum grain yield of 935 and 902 kg/ha, net profit of Rs 3934 and Rs 3320/ha with incremental cost benefit ratio of 11.2 and 10.9, respectively.
