【 摘 要 】

A field experiment was conducted at Al-Qaim area 90 km north of Basrah Province, Iraq during the growing season of 2018-2019. The purpose of this study was to evaluate the efficacy of three different herbicides includes Pallas 4.5%OD (125ml.Donum-2), Spotlight75%DWG(5g.Donum-2) and Clodex100EC (150ml.Donum-2) to control the weeds growing with two cultivars of wheat (Ebaa-99 and Buhooth-22). The results showed that Ebaa-99 cultivar was superior in the average of plant height (77.99 cm), flag leaf area (29.15cm2), number of tillers (701.50 tillers.m-2), number of spikes (615.61 spikes.m-2), weight of 1000 grain (43.41g), grain yield (5203.34 Kg.ton-2), biological yield (15216.58 Kg/ha), harvest indicator (35.25%), dry weight of narrow-leaved (14.14 g.m-2) and broad-leaved weeds (43.64g.m-2). While Buhooth-22 cultivar revealed superiority in the number of grains per spike (28.66 grain.spike-2), length of the spike (7.76 cm) and protein content (10.47%). Spraying treatments by the formulation of the herbicides Spotlight and Clodex were significantly exceeded other treatments in all crop plant growing components.
