Abstract: A sclerotial fungus Rhizoctonia bataticola (Taub.) Butler a pycnidial stage known as Macrophomina phaseolina (Tassi) Goid. The fungus causes complex disease syndromes like charcoal root, root rot, seedling blight, foliage blight, tuber decay, dry rot, fruit rot, pod and seed rot in several economically important crops. Yield losses up to 77 per cent reported in soy bean due to Rhizoctonia bataticola. In the present investigation, various factors were studied on root rot of soybean caused by Rhizoctonia bataticola. Rapid roving survey in the major soybean growing areas of Vidarbha revealed the prevalence of Rhizoctonia root rot at all the locations where disease incidence ranged from 2.33 to 39.33 per cent. Thirteen different isolates of Rhizoctonia bataticola were isolated from different regions of the Vidarbha. Pathogenic abilities of different isolates of R. Bataticola on soybean cultivar TAMS-38 a susceptible variety, confirmed the isolates of Rhizoctonia bataticola to be pathogenic. The isolates of R. Bataticola were tentatively divided in five groups based on their pathogenic reaction as highly, strongly, moderately and weakly pathogenic and nonpathogenic. Potato Dextrose Agar media were the best media for the growth of R. Bataticola
