A field experiment was conducted during rainy (Kharif) seasons of 2013 and 2014 at Agriculture Research Station, Mahatma Phule Agricultural University, Kasbe Digraj, Sangli, Maharashtra. Significant weed density reduction was recorded with fluthiacet-methyl at increased application rates of 5 g/ha to 15      g/ha. Fluthiacet-methyl 15 g/ha + 0.25% NIS controlled broad-leaved weeds effectively. Biomass and total broad-leaved weed density were the lowest with fluthiacet-methyl 15 g/ha + 0.25% NIS. Weed control efficiency was higher (80.86%) with fluthiacet-methyl 15 g/ha + 0.25% NIS. Seed yield was the highest (1.91 and 1.93 t/ha during 2013 and 2014, respectively) in weed free plot followed by fluthiacet-methyl 15 g/ha + 0.25% NIS applied as post-emergence (2-5 leaf stage of weeds) with the highest B:C ratio.
