Sheath blight of rice caused by Rhizoctonia solani
(Khun) is a potential threat to rice cultivation causing yield losses ranging from 32-70%. There are no host resistant varieties available so far. Fungicidal management for its control are damaging to environment. Eco-friendly approaches had attained major role in the suppression of the pathogen. Research studies are undertaken in order to reduce the incidence of the sheath blight all over the world. Seed and foliar spraying with Microbial agents such as Bacteria and Fungi provide the biological control of sheath blight.
It infects all the stage of the crop. As the primary infection initiates with soil borne sclerotia. So the reducing the soil borne inoculum by the addition of organic amendments viz. rice chaff, neem cake, mustard cake, saw dust and farmyard manure helps in reducing the seedling infection. The application of Bioagents such as Trichoderma harzianum + Pseudomonas Floroscens + farmyard manure prior to transplanting in soil gives maximum reduction in the severity of the Disease. The application of bioagents along with organic amendments will manage the disease effectively and shows positive correlation in the yield. This review gives the overall innovative eco-friendly approaches using today worldwide for environment friendly and economical management of the most destructive disease in rice ecosystem (Sheath Blight).
