Abstract:

The fungal disease sheath blight of rice caused by Rhizoctonia solani is an economically important disease of rice in India. A survey was carried out to find the disease severity of sheath blight of rice and collected the specimens from the different locations of Prayagraj district. Thirteen isolates of R. solani collected from different locations of Prayagraj district were studied for their morphological and cultural characterization. All isolates showed wide morphological and cultural variations in terms of colours (white, whitish yellow, light cream and pale-yellow) colony behavior (upper touch lid and no-upper touch lid), radial growth (slow, moderate and fast growing), sclerotia colour (brown, light brown, dark brown, and deep dark brown), sclerotia distribution pattern (scattered, peripheral and scattered-peripheral) and sclerotia weight (ranged between 0.123-0.233g).
