Bio-efficacy of Some New Herbicides against Weedin Transplanted Rice (Oryza sativa L.)

Pyrazosulfuron-ethyl at 25 g ha⁻¹ applied 10 days after transplanting (DAT), tank mixed (3 DAT) or sequential application of butachlor 938 g ha⁻¹ (3 DAT) and Almix at 4 g ha⁻¹ (25 DAT) were identified as promising alternatives to the commonly used herbicide butachlor at 1:5 kg ha⁻¹.
