An experiment was conducted in randomized biock design with 7 treatments comprising butachlor 1.5 kg/ha at 5-7 DAT, bispyribac-sodium 25 g ha at 15-20 DAT, bispyribac-sodium 35 g/ha at 15-20 DAT, bispyribac-sodium 50 g/ha at 15-20 DAT, weed-free, until harvest, two hand weedings at 20 and 40 days'after transplanting and unweeded control. Results revealed that application of bispyribac-sodium 50 g/ha at 15-20 DAT resulted in significantly higher grain yield (5.70 t/ha), which was at par with bispyribac-sodium 35 g/ha at 15-20 DAT. Number and dry weight of weeds was also minimum in these treatments.
