A field experiment was conducted at experimental Farm in Department of Field Crop Science, College
of Agriculture – University of Tikrit. During seasons of 2016- 2017 the effect of the interaction of five
herbicides for the control of narrow and broadest leaf wheat weeds in the field of wheat variety ( Sham
6)was assessed (Topik and traxos herbicides ) selective as control narrow leaf and the interaction with
the broadest leaf weeds herbicides (Cranstar) , (Harmony Extra) and (Lantor) According to the
recommended quantities and the effect of these herbicides on some of the growth charaeters and yield
components , The experiment was carried out by design of integrated random sectors and three
replicates . Results showed that the density of the weeds at the interaction between the Topik and
Lantor, rate 64% , While the interaction with Topik and Harmony herbicide achieved the highest height
of the wheat plant 57,80 cm The treatment of Topik and Harmony number of activists reached 5.50
branch/plant The treatment Traxos with Granstar gave the highest length of the spike which was
8,40 cm. Treatment Traxos with Garnastar gave the highest number of grains / spike at 30.53g
