An experiment was carried out during dry seasons of 1993 and 1994 at Cuttack (coastal alluvial soil) to evaluate herbicides for controlling weeds in puddle seeded rice. Among herbicides/herbicide combination sanilofos alone and in combination with 2,4-DEE showed higher degree of phytotoxicity on rice seedlings, while granular formulations of anilofos did not cause any phytotoxicity during 1993. During second year pre-emergence application of anilofos (0.4 and 0.6 kg/ha), anilofos +2,4 DEE (0.3 +0.42 kg/ha), butachlor (1.0 and 1.5 kg/ha) and pendimethalin (1.0 and 1.5 kg/ha) gave comparable yield to weed free treatment The weed control efficiency of these herbicides was upto 90.0 per cent. Application of anilofos + 2,4-DEE at both rates showed slight phytotoxicity during 1994.
