Field trials were conducted during 2015-19 by planting commercially grown rice cultivar TPS5 and TPS3 varieties during Kharif season (June–Sept) and Rabi season (Oct – Feb) respectively to investigate the management strategy for sheath rot and grain discolouration by using bio control agent, plant products and fungicides. Seed treatment with P. fluorescens (Pf1) @ 10g/kg + two foliar spray with Azoxystrobin 23SC (0.1%) performed better with lowest per cent incidence of sheath rot 9.09 and grain discoloration 8.46 in TPS5 rice variety during Kharif season and sheath rot 10.73 and grain discoloration 9.53 in TPS3 rice variety during Rabi seasons of 2016 to 2019 respectively. This treatment also recorded highest yield of 5252 Kg/ha in TPS5 and 5286 Kg/ha in TPS3 with a cost benefit (C:B) ratio of 1:2.02. This was followed by seed treatment with P. fluorescens (Pf1) @ 10g/kg + two foliar spray with liquid formulation of P. fluorescens (Pf1) @ 5ml /lit and has recorded comparatively better C:B ratio of 1:1.81.
