In order to evaluate the effect of reducing the use of herbicides to control wild mustard in canola varieties were different densities in the province of Alborz as split - factorial randomized complete block design with three replications and treatments include: Rapeseed (C) as the main factor (MP) on 2 level (including: (C1) Zarfam and (C2) option 500), and wild mustard density (D) in three levels (including (D1) zero, (D2) 7 and (D3) 15 plants per square meter) and herbicides. (H) in three levels (including (H1) 100%, (H2) 75% and (H3) 50% recommended dose) are as minor as a factorial was. The dry weight of weed species, rapeseed yield components, and seed yield and growth parameters were analyzed. Based on the results, the highest percentage of dry matter loss than control weed (weed), respectively C₁D₂H₂ treatments and C₂D₂H₁ and C₁D₂H₁ with 19/78, 12/78 and 0/78%, the highest percentage of dry matter loss had the lowest percentage of weeds and weed dry matter loss (18/48) of treatment was C₂D₃H₃. By comparison, average grain yield, in the presence and absence of wild mustard showed that the highest grain yield and the lowest in Option 500 is Zarfam. Manuscript profile

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. Manuscript profile
