A field experiment was carried out in the fields of one of the farmers in the province of Wasit Al-Ahrar area during the agricultural season 2015-2016 to control the wild barley and other weeds accompanied with the wheat. The experiment included six herbicides (Sulfon using 50 g.h−1, Granysam with 15 g.h−1, Granysam at the rate of use of 25 g.h−1, Bonanza rate of use of 100 g.h−1, Bonanza rate of use of 125 g.h−1 and 2,4 - D use rate of 1320 ml. h−1) and the treatment of weedy. Sulfon, Bonanza 100 g.h−1and Bonanza 125 g.h−1 herbicides affected significantly in reduced of weeds number of narrow leaves and its decreasing dry weight. While Sulfon, Granysam at a rate of 15 g.h−1, Granysam at a rate of 25 g.h−1 and 2.4-D in reducing weeds number of broad leaves and Its decreasing dry weight. The effect of herbicides in reducing the number of weeds and inhibiting their growth was reflected in a significant increase in the characteristics of the biological yield and the harvest index. The herbicides treatmeants were gave average of grain yield values 6.10, 5.28, 5.60, 5.55, 5.63, and 5.17 ton.h−1. average of biological yield values 14.17, 13.37, 13.23, 13.27, 13.8 and 12.93 ton.h−1. harvest index 43%, 40%, 42%, 42%, 41% and 40% respectively. It is concluded that the increase in grain yield with Sulfon was higher than the increase in other herbicides, due to the effect of this herbicides on a certain percentage on the broad weeds as well as its effect on the narrow weeds. This shows that the two-effect herbicides have a more positive result in increasing the yield. The efficacy of Bonanza herbicide affects reducing of wheat hight by a small percentage. The efficacy of Bonanza herbicide and Sulfon herbicide in control wild barley the numbers of weeds and its dry weight as well as their effect on the leaves narrow weeds. Granysam and 2.4-D had an effective effect in reducing the number and dry weight of the broad-leaf weeds.
