A pot experiment was conducted to study Setaria viridis L. control with different plant materials including: Common Sowthistle (Sonchus oleraceus L.) (whole aerial powder), Canola (Brassica napus L.) (seed meal), Lavender (Lavandula officinalis L.) (essential oil), Rosemary (Rosmarinus officinalis L.) (essential oil), Waxy Leaf Mustard (Boreava orientalis L.) (aqueous extract), in natural condition at University of Kurdistan, in 2018. The treatments arranged in randomized complete blocks design and were performed in 4 replications. The treatments were applied simultaneously with the sowing of Setariaseeds. The results showed that Lavender (345.6 mg) and Boreava aqueous extract treatments had the lowest leaf area and fresh weight compared to the control.Canola treatments had no significant effect on Setaria dry weight and there was no significant difference with control. The other treatments significantly reduced Setaria dry weight. Therefore, according to the results, using high concentrations of Lavender essential oil, as well as aqueous extract of wax mustard, can have a positive effect on population reduction and weed competition in valuable crops such as strawberries that are economically viable and may reduce the use of herbicides relatively.
