Paddy is the most widely cultivated food crop in the world. Sheath blight disease of rice caused by Rhizoctonia solaniis a major production constraint in all rice producing areas of the world.  The annual losses due to sheath blight of rice are estimated to be 25 per cent under optimum conditions of disease development. The experiment was conducted in central research farm of Department of Plant Pathology SHIATS, Allahabad during Kharif  season in the year of 2014. For present study seven treatments including control were evaluated for management of sheath blight of rice which were Trichodermaharizanum (Seed treatment) + Trichoderma varied (Foliar spray), T. viride (ST) + Psudomonas fluorescens (FS),  P.  fluorescens  (ST) + T. viride (FS),  P. fluorescens (ST) + T. harizanum  (FS),  T. viride (ST) + T. harizanum  (FS) , carbendazim  (ST) + propiconazole (FS)  and Control. Observations recorded on 90 DAT pertaining to mean per cent disease severity reveal that it was lowest with carbendazim (ST) + propiconazole (FS) 17.55, followed by T. viride (ST) + T. harizanum (FS) 18.96, P. fluorescens (ST) + T. harizanum (FS) 19.77, T. viride (ST) + P.  fluorescens (FS) 21.18,P.  fluorescens (ST) + T. viride (FS) 22.00, T. harizanum  (ST) + T.  viride (FS) 22.29,and control 29.10.
