Efficacy of pyrazosulfuron-ethyl against weeds in transplanted rice was studied during 2008 and 2009 at Regional Research Sub-station, Chakdaha under Bidhan Chandra Krishi Viswavidyalaya, West Bengal. The experiment was laid out in randomized block design with seven treatments replicated thrice. The major associated weeds were: Echinochloa colona, Cyperus difformis, Ammania baccifera, Ludwigia octovalvis and Monochoria vaginalis. Pyrazosulfuron-ethyl at 42.0 g/ha applied at 3 DAT was most effective in managing associated weed species and yielded maximum grain yield (3.3 t/ha) of rice with lower weed index (10.8%).
