A total of seven isolates of two different Trichoderma spp. were isolated from the rhizosphere of groundnut from different locations of Manipur. In vitro study on the effect of Trichoderma isolates on the growth of Sclerotium rolfsii ranges from71.85 - 61.11per cent. Effect of volatile compound produced by Trichoderma spp. against S. rolfsii showed inhibition ranged from20.00 - 30.00 per cent and for non-volatile compound 11.47- 30.7 per cent at 7.5 % v/v concentrations and 20.77- 47.78 per cent at 15 % v/v. Experiment on ecological adaptability of two potent T. viride showed variation in the colonization of sclerotia under three different soil conditions. The rhizosphere competence of two potent isolates of T. viride viz., TvG1 andTvG2 at different days after sowing showed variation in the levels of colonization under three different soil conditions. In vivo study on efficacy of two potent isolates showed reduction in stem rot of groundnut among the different treatments (seed, soil and seed plus soil). The treatment with seed + soil of Trichoderma isolates TvG1 and TvG2 recorded the highest plant height, plant canopy, fresh weight, dry weight and yield, but no significant difference in chlorophyll content among treatments.
