An experiment was conducted at Malakandher Research Farm, NWFP Agricultural University, Peshawar during 2000-2001 using RCB design, having four replications. Dunkled Variety of canola in a plot size of 6x3m2 was planted during the last week of October, 2000. The data were recorded on weed density m-2, days to 50% flowering, 1000 seed weight (g) and seed yield (kg per ha). None of the herbicides except Sencor WP70 had a phytotoxic effect on the crop. All the parameters were significantly affected by different herbicidal treatments. Minimum weeds 3.20 m-2 were observed in plots to which Treflan 4EC was applied as compared to 18.83 weeds m-2 counted in the weedy check plots. Thousand seed weight (3.68 g) and seed yield (1568 kg per ha) were also maximum in the plots to which Treflan 4EC was applied as pre-emergence herbicide.
