Bio-efficacy of anilofos formulations on weed dynamics in transplanted rice (Oryza sativa L.) was studied during rainy season of 2006–07 at Varanasi. Application of anilofos 600 g/ha 30 Gr with emulsifier (T3) was most effective in minimizing the density of Echinochloa colona and total weed density as compared to other herbicidal treatments at all the stages of observation and it were at par to anilofos 450 g/ha Gr with emulsifier (T2). Among the herbicidal treatments maximum density of Echinochloa colona as well as other weed species recorded with anilofos 300 g/ha Gr without emulsifier (T4). Anilofos 600 g/ha Gr with emulsifier (T3), significantly reduced density of Echinochloa colona and other weeds, resulted maximum crop growth, yield attributing characters and grain (5761 kg/ha) and it was closely followed by anilofos 450 g/ha Gr with emulsifier (T2) and anilofos 600 g/ha without emulsifier (T6). These herbicides had stunted growth and discoloration of rice plant and necrotic spot on the leaf 11 DAT, but within a week crop recovered these phytotoxic effects.
