tailieunhanh - Assessment of method of application of microbial antagonist for the management of sheath rot disease of rice under green house condition

Sheath rot disease caused by S. oryzae has emerged as one of the major diseases of rice inflicting yield losses ranging from to 85% depending on the weather conditions. Pesticides are mostly used for its management and application of these chemicals over a long period may result in development of resistance, pesticide residue risk, health and environmental issues which necessitates an alternative economically feasible eco-friendly method for its management. The present investigation was undertaken to evaluate the effect of method of application of microbial antagonists in suppression of sheath rot disease of rice under green house condition. Talcum powder based bio-formulation of P. fluorescens (109 cfu/ml) was found most effective when applied in combination as seed treatment, seedling root dip treatment and foliar spray at boot leaf stage in reducing maximum DI () and PDI () over control and also found to increase the yield attributing characters and grain yield to the tune of % over control under greenhouse condition. | Assessment of method of application of microbial antagonist for the management of sheath rot disease of rice under green house condition
