Weeds are one of the organisms that interfere with plants and can reduce rice productivity because they compete directly for nutrients, light, water, and growing space. Controlling weeds using systemic and selective herbicides is considered more effective in controlling weeds in rice cultivation than other methods. This study aims to determine the effective mixture dosage of the herbicides Bispyribac Sodium 150 g/L and Cyhalofop-Butyl 50 g/L at a rate of 50–150 ml/ha to suppress weed growth and enhance the productivity of irrigated rice crops of the SR-P 08 variety. The study was conducted from August to December 2024 at the SPLPP Faculty of Agriculture, Padjadjaran University. The study was conducted using a Randomized Block Design with 7 treatments and 4 replications. The treatments consisted of the following herbicide mixture doses: Bispyribac Sodium 150 g/L and Cyhalofop-Butyl 50 g/L at rates of (A=50 ml/ha), (B=75 ml/ha), (C=100 ml/ha), (D=125 ml/ha), (E=150 ml/ha), (F=Manual weed control), and (G=Without weed control). The results showed that the herbicide mixture of Bispyribac Sodium 150 g/L and Cyhalofop-Butyl 50 g/L at doses of 50–150 ml/ha effectively suppressed the weight of broadleaf (Monochoria Vaginalis, Ludwigia Octovalvis) sedge (Cyperus iria), grasses (Echinochloa crussgalli) and total weeds up to 6 weeks after sowing and had a positive effect on the growth and yield of the rice variety SR P-08
