Abstract
The experiment was carried out at College of Agriculture and forestry , Mosul Univ. at Hammam Al-Alil in 2003 growing season to determine the effeicency of six systemic herbicides with three levels of concentration for control Sorghum halepense(L) . Data was subjected to the conventional analysis of randomized complete block design (R،C,B,D)as a sample experiment with three replicates .Results indicated that glyphosate (232ml a.i / ha) , Focus altra (150 ml a.i./ha) and Fuselate (33 ml a.i ./ha ) had completely control S . halepenses , while others herbicides such as Topic , Illoxan and super galant had less effected .These three herbicides had more effect on rhizom dry weight than on shoot of plant which reduce 76.6 % for Topic , 46.6 % for Illoxane and 66.6 % for super galent if it compered with the check treatment ( no herbicide).
