Sheath rot of rice, one of the serious diseases of rice caused by Sarocladium oryzae has resulted in heavy yield loss in the state of Tamil Nadu. Hence, the present work was carried out to study the management of sheath rot of rice using endophytic plant growth promoting bacteria (EPGPB). The population was enumerated by serial dilution technique and the endophytes were found to be higher in ADT 42 variety with the population of 4 × 106 cfu g−1 of tissue. Seed bacterization (SB) + seedling root dip (SRD) + spray with endophytes under milky stage and boot leaf stage were found to increase the vigor index of rice seedlings significantly. The increase in mean plant height (87 cm) and 1000 grain weight (26 g) due to Seed bacterization (SB) + seedling root dip (SRD) + spray with endophytes.
