Abstract

                                The control of sheath blight disease of rice caused by Rhizoctonia solani was attempted. Field experiments were conducted for two seasons with susceptible rice variety ADT. 31. The test fungicides viz., Benlate, Dexon, Wettable coresan. Daconil, Dithane Z-78. Dithane D-14. Kitazin, Hinosan, NF-48. Brassicol, Brostan. EL-273 Thiram and Demosan at 0.2 per cent level were sprayed twice, during maximum tiller- ing phase of the crop. The rice plants were inoculated with R. Solani before spraying. All the fungicides sprayed plots have reduced the disease and increased the grain yield. Benlate, Kitazin, Hinosan, Demosan and Daconil were found to be highly effec- tive in controlling the disease and these fungicides have also increased the grain yield significantly in both Kuruval and Theladi seasons.
