Abstract: Avena sterilis is problematic weed that affects wheat production. The aim of this study is to investigate the effect of Clodinafop-propargyl on A. sterilis 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. Trial were conducted in Ouazzane region of Morocco in January 2018. Treatments were carried out with a knapsack sprayer with the nozzle delivering a 3 bar jet. A quadrant of 1m x 1m was used to calculate percentage of A. sterilis density reduction and biomass reduction. A. sterilis dry biomass were determined using an oven at 75 ° C for 48 hours. Then, weighed with a precision balance. Results showed that treatments with Clodinafop-propargyl at 60 g/ha and 80 g/ha gave the best control of A. sterilis infestations recording respectively 96.1% and 99.4% of A. sterilis density reduction and 98.2% and 99.7% of A. sterilis dry biomass reduction. Clodinafop-propargyl at 40 g/ha recorded lower efficacies 75.3% and 80.1% respectively on A. sterilis density reduction, and A. sterilis dry biomass reduction.
