An experiment was conducted at Sher-e-Bangla Agricultural University, Bangladesh to evaluate the efficacy of different fungicides against major foliar diseases of rice, namely brown spot (Bipolarisoryzae), blast (Pyriculariagrisea), narrow brown leaf spot (Cercosporaoryzae) and sheath rot (Sarocladiumoryzae). Nine fungicides such as Knowin 50 WP 0.2%, Score 250 EC 0.1%, Control 15 EC 0.1%, Proud 25 EC 0.1%, Tilt 250 EC 0.2%, Folicure 250 EW 0.1%, Sunvit 50 WP 0.7%, Cupravit 50 WP 0.7% and Bordeaux Mixture (CuSO4 2.27g: CuO 2.27g: H2O 100ml) were sprayed at maximum tillering stage to control the diseases. All fungicides were effective in reducing the incidence of aforesaid diseases at flowering, milking, dough and maturity stages. The effect of Tilt 250 EC 0.2% (Propiconazole) and Proud 25 EC 0.1% (Propiconazole) were better than the other fungicides in controlling those diseases, resulted higher yield. In maturity stage, the highest disease severity of brown spot and sheath rot were found in the control (untreated) while the lowest severity was observed in Tilt 250 EC 0.2%. Proud 25 EC 0.1% also showed the lowest severity of blast and narrow brown spot at maturity stage. The highest grain yield (4.75t ha-1) was recorded at treatment, Tilt 250 EC 0.2%. Therefore, Tilt 250 EC 0.2% and Proud 25 EC 0.1% can be recommended to control the foliar diseases of rice which help to increase the grain yield of that crop.
