Abstract :This study was conducted to investigate the effect of various concentrations of Apyrus and Othello herbicides on the common mallow weed control and their possible negative effect on wheat yield in 2017-18 in Ahwaz, Iran. The treatments were Othello at concentrations of 1.25, 1.5, and 1.75 L/ha and Apyrus at 24.6, 26.6, and 30.6 g/ha. Results showed that herbicide treatments significantly reduced common mallow weed density and dry weight after spraying insert ignore into journalissuearticles values(15 and 30 days after application);. Best results in reducing the common mallow weed density and dry weight were recorded in 30.6, 26.6 g/ha of Apyrus, and 1.75 and 1.5 L/ha of Othello. The effect of treatments was also significant on wheat plant height, spike number per plant, grain number per spike, 1000-grain weight, biological yield, and grain yield. The highest wheat grain yield insert ignore into journalissuearticles values(4359 kg/ha); was obtained in no-weed control, and among the herbicide treatments, the highest wheat grain yield insert ignore into journalissuearticles values(3981 kg/ha); was obtained by 1.75 L/ha of Othello, followed by 26.6 g/ha of Apyrus; while, these yields were not significantly different. Therefore, to control the broadleaf common mallow weed in wheat fields by using Apyrus herbicide, a lower dose of this herbicide insert ignore into journalissuearticles values(dose of 26.6 g/ha); could be used. Also 1.75 L/ha is a more acceptable application rate for Othello herbicide to control the common mallow weed in wheat fields.
