Abstract: Greengram (Vigna radiata L.) is one of the most important conventional pulse crop grown in the Vidarbha region of Maharashtra. It plays an important role not only in human diet but also in improving soil fertility by fixing atmospheric nitrogen. Root rot of greengram caused by Rhizoctonia bataticola is an economically important disease of greengram. In pot culture experiment, the seed treated with Thiophanate methyl @ 0.1% which was recorded least (29.62) percent disease incidence at 30, 60 and 90 DAS. In vitro evalution of fungicide showed cent Percent growth inhibition (100%) radial mycelial growth of Rhizoctonia bataticola in all fungicide treatments. In respect of bioagent, T. viride showed (86.02%) highest growth inhibition against the pathogen. Different seed treatments and soil amendments were evaluated for counting dynamic population and inoculums density of Rhizoctonia bataticola. The propagules of pathogen was observed per gram of soil. Minimum number of propagules were noticed in T4 treatment Thiophanate methyl (5.66 and 4.33%). Effect of various seed treatments on germination, shoot length, root length and seedling vigour index was recorded. Highest germination (81.66%), shoot length (10.77 cm), root length (9.27 cm) and also highest seedling vigour index (1636.46) were recorded in Thiram + Carbendazim.
