Both acetochlor and isoproturon are suitable for post-emergence or post-three-leaf soil sealing treatment in wheat fields and wheat fields. Both of them have certain control effects on weeds in seedling stage, and isoproterenol is relatively large. Weed control is also good. The two can be mixed and used. At present, the compounding agent of isoproturon and acetochlor is registered in the wheat field for weeding. After mixing, the herbicide spectrum is enlarged, and the relatively low dosage is beneficial to reduce the phytotoxicity. The herbicidal effect mainly depends on soil moisture, grass age and grass phase. It should be used in the early stage of weed seed germination or germination. The soil moisture is suitable for improving the control effect when applying the fertilizer. The herbicidal effect is poor when the soil is dry, and the soil is too wet. When the wheat seedlings are susceptible to acetochlor.
