Abstract: Lolium rigidum is a harmful weed specie in wheat crops. The aim of this study is to investigate the effect of Clodinafop-propargyl on Lolium rigidum infestation in a soft wheat crop. The experimental design was Randomized Complete Block Design (RCBD) with three replications. Each block contained 4 elementary plots, 3 plots of which were treated with three rates of application of Clodinafop-propargyl and one untreated control plot. Observations concerned Percentage of Lolium rigidum density reduction and biomass reduction. Results showed that treatments with Clodinafop-propargyl at 60 g/ha and 80 g/ha gave the best control of Lolium rigidum infestations recording respectively 95.1% and 96.8% of Lolium rigidum density reduction and 92.5% and 64.6% of Lolium rigidum dry biomass reduction. Clodinafop-propargyl at 40 g/ha recorded lower efficacies 65.7% and 61.9% respectively on Lolium rigidum density reduction, and Lolium rigidum dry biomass reduction.
