This study aimed to investigate Tasyrlfksh used in canola on the growth and competitiveness of the plant with weed in 1388 in a randomized complete block design with four replications in Alborz Province (Hashtgerd) came into force. The treatments were: Lasso (alachlor), Butyzan Star (Mtaraklr + Queen Merak), Tryduks (Dymtaklr), Treflan (trifluralin), Gallant Super (Hallux Fup-R-methyl ester), Sonalan (Ethalfluralin), Treflan + Gallant Super, without control and weed control. In this experiment, characteristics such as percent dry weight of weed species, yield and yield performance were analyzed. The results showed that among herbicides, Butyzan Star (5/2 Lit / ha) had the highest percentage of weed dry weight loss (42/86) and herbicide Treflan (2 Lit / ha) had the lowest percentage of dry weight the weeds (55/65), which is why most (2307 Kg / ha) and lowest (1990 Kg / ha) grain yield was highly above mentioned treatments. In between treatments, the highest yield without weed control with 2409Kg / ha and the lowest yield weed control with 1862Kg / ha and accounted for.
