Effect of Certain Fungicides on the Growth and Sclerotial Production of Rhizoctonia Solani

Twenty five fungiciles were tested against the growth of Rhizoctonia solani—the incitant of sheath blight disease of rice under laboratory condition. Of the twenty five fungieidee tested bavistin, NF-48, vitavax, benlate, brassicol, thiabendazole, hinosan, daconil, demosan and kitazin have completely inhibited the growth and selerotial production even at 0.025 concentration while the fungicides agallol, thiram, captan, EL-273, dexon and agrosan have inhibited the growth and sclerotial produc-tion of the fungus only at 0.2 per cent level. All the fungicides tested have inhibited the growth of the pathogsa to varying degreees compared to control.
