Abstract:
The current study assessed the effects of common herbicides produced by different companies on broadleaved and grass weed control and quantitative traits of irrigated wheat. A two-year experiment (۲۰۱۳-۲۰۱۴ and ۲۰۱۴-۲۰۱۵) was designed as an RCBD with three replications. Experimental treatments included two control treatments (weedy and weed-free) and ۱۵ herbicides produced by three Iranian companies (Ghazal, Golsam-Gorgan, and Gyah) and three international companies (BASF, Nufarm, and Syngenta). The results showed that H۱۳ (bromoxynil + MCPA from BASF tank-mixed with clodinafop propargyl from Golsam Gorgan) and H۱۴ (bromoxynil + MCPA from BASF tank mixed with clodinafop propargyl from Ghazal) treatments in ۲۰۱۴ and H۵ (tribenuron methyl from Gyah) and H۹ (clodinafop propargyl tank-mixed with tribenuron methyl from Golsam Gorgan) in ۲۰۱۵ almost completely controlled broadleaved and grass weeds. In ۲۰۱۴, H۴ (۲,۴-D + MCPA from Nufarm) and H۱۳ treatments with the averages of ۷۵۰۵ and ۷۳۳۸ kg ha-۱ ranked first and second in grain yield, while H۹ and H۱۲ (bromoxynil + MCPA from BASF tank-mixed with clodinafop propargyl from Gyah) with the averages of ۷۹۶۶ and ۷۹۱۷ kg ha-۱ were known as superior treatments in ۲۰۱۵. Averaged by years, the grain yield was ۳۱۸۵ kg ha-۱ at weedy treatment (H۱۷). Although there were no significant differences between herbicides, the grain yield (averaged by years and herbicides) was boosted by ۸۸% compared with the weedy treatment. It was concluded that more rainfall and desirable air temperature positively affected the efficacy of the herbicides.
