This experiment was conducted in the summer agricultural season 2021 in theagricultural field of a farmer in the village of Suleiman Al-Gharb of Hawija district -governorate, where the land was plowed by two orthogonal plows, and the field wasdivided into three replicates, and each replicator contains eight experimental units,and each experimental unit has dimensions of 4×4. Each experimental unit has fivelines. Trifluralin was sprayed before planting and mixed with the soil well. The localvariety of sesame seeds were planted and planted in the seventh month, 11/7/2021,and the amount of seeds was from (3-2.5 kg of acres) or 7- 12) kg hectare.The results showed the following:The superiority of Fluazi Fop-butyl + manual hoeing at a concentration of 2.400 cm2/ha in the percentage of total weeds, weeds dry weight, dry weight, 1000 grainweight, grain yield, yield and biological yieldFluazi Fop-butyl + manual hoeing was used at the recommended concentration for thetotal number of weeds, for the dry weight, for the weight of 1000 grains, as well as forthe biological yield, as well as the higher concentration than the recommendedamount of 500 cm 3 / ha-1
