The critical period for weed control was found to be between 20 - 40 days after <br />planting of soybean (c. v. Wilis) grown at a planting distance of 40 x 10 cm. It did not coincide with the fastest <br />growth  in  terms of  trifoliate  leaf number. Further studies were suggested  to understand the physiological <br />growth of soybean related to weed control. <br />Pendimethalin at 660- 1320 g a.e./ha applied one day after sowing did not cause any phytotoxic effect to <br />soybean and had good weed control performance.
