Abstract
A field trial was conducted to evaluate the efficacy of some selective herbicides on narrow leaf weeds grown in
wheat fields. Buhooth 22 was cultivated during the winter season 2017-2018 at the Abu Ghraib Research Station of the
Ministry of Agriculture’s Department of Agricultural Research. The trial included the use of three herbicides (Reward 10% EC,
Traxos 050 EC at two levels and Topik 100 EC) in addition to the weedy controlled treatment with three replications and using
a Randomized complete block design (RCBD). The Reward EC 10 % treatment attained the lowest density of weeds, reaching
one plant.m2 with a control rate of 96.96% and a lesser weeds dry weight (2.40 gm.m-2) with either an inhibition rate (95.74%)
in comparison with the control treatment, which provided an average of 33 plants.m-2 and revealed a positive average weed
dry weight (54.43 gm.m-2). The use of the similar herbicide culminated in a rise in grain. Grain with a rate of 37.94% and a weight
of 1000 grains by 32.43% and that was reflected in grain yield increment by 82.78% compared to the weedy treatment, which
gave the lowest yield rate of 3.328 tons.ha-1. We conclude from the above that both herbicides had a significant effect on all
the studied traits and at different rates compared to the weedy treatment, although the Reward 10% EC herbicide treatment
significantly outperformed other treatments in the low use rate, the number of weeds, the percentage (%) of control, inhibiting
and plant height, while there were no significant differences in the weedy treatment.
