Since the planting of wheat, herbicides have not been used until now. There are not many weeds in the field. Can they be treated with isoproturon? Wheat seedlings have not been used until now, and the soil can be closed with isoproturon before the weeds are released. Isoproturon has both soil sealing and stem and leaf treatment effects. Application of weeds before weeding out prevents both weeds and weed seeds from germination.
