In order to investigate the herbicides sulfosulfuron and mesosulfuron methyl + iodosulfuron methyl-sodium in pure form and together with salicylic acid in the control of weeds, yield and yield components of wheat, a study was carried out in 2021 in the research farm of Lorestan University. The experiment was carried out factorially based on a randomized complete block design (RCBD) in three replications. The first factor included the application of the recommended dose and 50% of each of sulfosulfuron (Apirus, 75% WG) and mesosulfuron methyl + iodosulfuron methyl-sodium (Atlantis, 1.2% OD) herbicides. The second factor was foliar spraying of salicylic acid in combination with herbicide treatments. The results showed that the lowest density (0.2) and dry weight (0.4242) was related to Asperugo procumbens L. Also, the reduction of dry weight of weeds and the highest number of seeds per spike, height, number of spikes per square meter, seed yield and chlorophyll (a and b) were obtained from the application of (Apirus + Atlantis with salicylic acid). Based on the obtained results, it is recommended to use salicylic acid along with herbicides to increase wheat yield and reduce weeds.
