Brown spot of rice incited by Drechslera oryzae (Breda de Haan) Subramanian and Jain is the most important disease of rice. Regular occurence of disease and heavy yield losses caused by this disease in Bihar prompted us to undertake the studies. Out of seven fungicides tested Antracol 75 WP (1.5 g/l) and RIL-FA 200SC (2.5 ml/l) reduced the disease severity and increased the yield. Among the biopesticides Tricure (5 ml/l), Biotos (2.5 ml/l) and Achook (5 ml/l) were found significantly effective in checking the brown spot severity and increasing the yield.
