In order to assess how effectively different herbicides work in controlling the wild radish weed that are connected with the growth of the wheat crop, The experiment included one factor he four types of chemical herbicides: Navigator, Tatsteler, Decimate and Mark zone,in addition to comparison treatment. and with three replications, according to the randomized complete block design (R.C.B.D). When the process of preparing the soil of the field was carried out, artificial infection of the wheat seeds the Al-Wafia variety was carried out, by adding 0.5 gm of wild radish weed seeds. After that, the polluted wheat seeds were sown, and when the wild radish weeds reached the appropriate stage for control, herbicides were added according to the recommendation of the producing company some characteristics were taken from the wild radish weed after 60 and 90 days of control, as well as some characteristics of the wheat plant and its yield components, results were as follows: excellence the two herbicide, Navigator and Decimate, were superior in reducing most of the studied traits of wild radish weeds, as shown the results show Navigator excelled by giving it the highest average of chlorophyll index, which reached 50.71 SPAD, and in flag leaf area, which averaged 49.64 cm, in ddition to its superiority in grain yield, with an average of 5.83 tons. ha-1 and in the harvest index also gave the highest average of %36.92, as it was noted that Tatsteler herbicide was superior in the tillers number with an average of 472.33 tiller m-2 and in the spikes number of also excelled with an average of 423.57 spike m-2 . as for the Mark zone herbicide, it excelled in the weight of 1000 grains, with an average of 40.10 g. also it was noted that Decimate had superiority in biological yield with an average of 15.13 ton ha-1, but it did not differ significantly from the averages of Navigator and Tatsteler, which were 15.09 and 15.06 ton ha-1 respectively.
