Manage sheath rot of rice

A new combination fungicide TAQAT 75% WP (Captan 70% + Hexaconazole 5%) was tested in different doses against rice sheath blight (ShB), sheath rot (ShR) and stem rot (StR) diseases under field conditions during Kharif 2013 and Rabi 2013-14.

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.

Rice, Results obtained in the experiments conducted to find out effect of seed bio-priming on management of sheath blight and sheath rot diseases of rice in field condition revealed that seed bio-primed with Trichoderma harzianum applied at imbibition was proved to be an excellent bio-agent to manage sheath blight (Rhizoctonia solani) with minimum disease incidence (25.67%) and severity (21.63%) whereas Pseudomonas fluorescens applied at imbibition significantly manage sheath rot (Sarocladium oryzae) with minimum disease incidence (28.67%) and severity (23.41%).

Prior to the introduction of the modern varieties, the rice crop survived for centuries with traditional varieties with robust plant type but low yield. The farmers started applying higher doses of fertilizers in general and nitrogen in particular as these varieties were fertilizer responsive and these changes in rice cultivation resulted in an altered microclimate, which led to the accentuation of the insect pest and disease problems. Many diseases such as sheath blight, sheath rot, false smut and leaf scald have become severe in several parts of the country.

Sheath rot disease caused by S. oryzae has emerged as one of the major diseases of rice inflicting yield losses ranging from 9.6 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.

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.
