A field experiment was conducted during two monsoon seasons to find out the efficacy of certain low doses herbicides in transplanted rice. Echinochloa colona, Echinochloa crusgalli, Cyperus rotundus, Cyperus difformis, Fimbristylis milliacea and Ludwigia parviflora were the major weeds. Almix+2, 4-DEE at 15+500 g ha·1 applied eight days after transplanting was found most effective in controlling weeds and maximizing rice grain yield (5837 kg ha·1). This was on par with hand weeding done thrice at 20, 40 and 60 days stage. The weed competition in weedy check caused 46% reduction in grain yield.
