Abstract: A field experiment was conducted at Kalyani \'C\' Block Farm, Bidhan Chandra Krishi Viswavidyalaya during kharif seasons of 2012-13 and 2013-14 to study the bioefficacy of Chlorimuron Ethyl 25% WP on transplanted rice cv. Shatabdi (IET 4786) in Inceptisol of West Bengal. Chlorimuron Ethyl 25% WP from @ 3.0 - 12.0 g.a.i. ha–1 recorded better weed control efficiency and twice hand weeding recorded the highest grain yield . However, Chlorimuron Ethyl 25% WP@ 6.0, 9.0 and 12.0 g.a.i. ha–1 and Kloben @ 6g a.i. ha-1 were statistically at par with each other. There were no significant variations on the microbial population of the soil in the rhizospere region of the transplanted rice due to the application of testing herbicide chlorimuron ethyl 25% WP..
