Sheath rot disease of rice is an emerging disease of rice inflicting severe yield losses. Chemical pesticides are exclusively used for the management of the disease and application of these chemicals over a long period may result in development of resistance, concerns about pesticide residue risk, health and environmental pollution and health hazards which demands for a sustainable means of disease management. The present investigation was carried out to evaluate the efficacy of few microbial antagonist viz. Trichoderma harzianum, T. asperellum, T. viride, T. pseudokoningii, T. parareesei, Pseudomonas fluorescens, Bacillus megaterium and Bacillus subtilis against Sarocladium oryzae in vitro. All the microbial antagonists were found to be effective in inhibiting the radial growth of S. oryzae. Out of all the tested antagonists, Pseudomonas fluorescence showed highest (82.06%) inhibition of the mycelial growth of the pathogen. Among the fungal antagonists, T. harzianum was found to be most effective with 65.21 % inhibition over the other species.
