Different cultural practicesviz.burning, sun‐drying of the stubbles, formaldehyde treatment of the soil and flooding were tried to control stem‐rot disease of rice incited byMagnaporthe salvinii(Catt.) Krause and Webster(Sclerotium oryzaeCatt.) for six consecutive seasons both summer and winter from 1980–82. The burning of straw and stubbles was the best of all cultural treatments and reduced the severity of the stem‐rot of rice by about 85% over the control (untreated soil). Formaldehyde solution (2%) treatment also reduced the incidence of the disease to an extent of 54% over the control.
