An experiment to study the effect of various chemical and conventional weed control methods on the performance of canola was conducted at the Agricultural Research Farm of NWFP Agricultural University, Peshawar during winter 1999-2000. The experiment was laid out in randomized complete block design with four replications. Minimum weeds per m2 (1.50) were observed in plots to which isoprotron 75 WP at the rate of 520 g per acre was applied. Plant height (161.8cm), number of pods per plant (609.9), number of grains per pod (28), 1000 grain weight (4.415g) and grain yield (1595 kg/ha) were maximum for plots applied with isoprotron 75 WP at the rate of 520 g per acre as pre-emergence herbicide. It is concluded that isoprotron 75 WP was the most effective herbicide for the control of most of the weeds as compared to other herbicides and conventional methods of weed control.
