| Field experimentes were carried out at the farm of Dept. of Field Crop Sciences, College of Agriculture , University of Baghdad , during winter seasons of (2009-2011), to evaluate the response of wheat to weed control by some herbicides and their mixture of [Florasulam+ Aminopyralid] Lancelot+ [Pyroxsulam]Pallas), (Clodinafop-methyl) Topic Logran, (Terbutryn +Triasulfuron) and Chevalier (Iodosulfuron+Mesosulfuron) The treatment of lancelot 32gm .ha-2 +Pallas 500 cm3.ha-2 gave less density of weeds (3.1 plant.m2) and achived completel weed control such as Avena fatua L, lolium temulentem, Mava paraviflora, Ammi majus,melilotus indicus L and polygonum avicularo , also reduced dry weight of narrow leave weed to 93.5% and broad leave weed to 99.2% compared to weedy treatment. These result increased wheat yield and produced highest number of grain per spike (61.2 grain)and yield grain of 933.5 gm.m-2. Other herbicides treatments showed different result in reduceing number of weeds, for example chevalier gave 22.3 plant.m-2 and Topik gave 61.6 plant.m-2. The best treatment was the combination of (Pallas 500 cm3.m-2 +Lancolat 32g.m-2) which gave the highest grain yield of 933.5gm.m-2 | ||
