AbstractThe experiment was carried out at al-Alkosh location in Nineveh Governorate in the agricultural season of 2009-2010. The aim of the present research is to study the effect of OD Pallas herbicide with three doses (45, 50.4 و 56.25g/donum) ,Chevalier (11.25g/donum) and Granstar(37.5g/donum) + Topic (15g/donum) herbicides in controlling broad and narrow leaf weeds growing with durum wheat um rabee variety and to obtain the effect of these treatment on the yield of wheat. The experiment was set out as Randomized Complete Block Design with three replicates. The results showed that OD Pallas gave a significant reduction in the number of broad and narrow leaf weeds and their dry weights and this results had a positive reflect in increasing the yield of wheat. The highest yield production of wheat was obtained with using OD Pallas at concentration of 125 cm³/donum(336,3 kg/donum) whereas the yield in the control treatment was only 110 kg/donum . Furthermore the presence of weeds in the control treatment led to a reduction in the yield production of up to 59,4%.
