Abstract
A field experiment was carried out during the 2017/2018 winter season in the Abu Ghraib Research Station, Department of
Agricultural Research, Ministry of Agriculture to assess the effectiveness of control broad-leaf weeds growing in the field of
wheat variety Buhooth 22. The experiment included use three herbicides, Spotlight 75 DWG (80 g. h-1), 2, 4-D (1330 ml. h-1),
and Lintur WG (180 ml.h-1), as well as weedy treatment. The experimental design was a randomized complete block design
(RCBD) with three replication. The Lintur herbicide treatment has been achieved the lowest number of weeds (1.3 plant.m-2)
with control percent of 94.7%, and reduce the dry weight of the weeds (4.3 gm.m-2) with inhibition percent of 95.2% compared
to weedy treatment which recorded the highest average for the number of weeds was 26.7 plants.m-2 and the highest average
dry weight of weed plants (90.9 gm.m-2). The Spotlight and 2.4-D treatments did not differ significantly from Lintur treatment
in weed density, control ratio, weed dry weight, and inhibition percent. The treatment of Lintur WG gave the number of spikes
(364.0 sp.m-2), seed per spike (69.33), and 1000 seed weight (36.26 g), which was positively reflected in the increase of grain
yield by (68.8%) compared to the weedy treatment. We conclude from the above that all the herbicides used have reduced the
number of weeds and their dry weights have been reduced by varying percentages depending on the nature of the chemical
composition of the herbicide compared to the comparison treatment and thus increasing the yield and its components.
