Can isoproturon and Acetochlor be mixed?
Can isoproturon and Acetochlor be mixed? Please introduce that Acetochlor and isoproturon are suitable for soil closure treatment in wheat and barley fields before and after sowing, and both of them have certain control effect on weeds in seedling stage, and isoproturon has better control effect on older weeds. The two can be mixed and used. at present, the mixture of isoproturon and Acetochlor is registered for weeding in wheat field. After mixed use, the herbicide spectrum is expanded, and their respective dosage is relatively low, which is beneficial to reduce the drug damage. The weeding effect mainly depends on soil moisture, grass age and grass phase. It is appropriate to use pesticides before weed seeds germinate or in the early stage of germination. Soil moisture is suitable to improve the control effect, but the weeding effect is poor when the soil is dry. Wheat seedlings are vulnerable to Acetochlor when the soil is too wet.
