Diuron 4L Herbicide provides effective pre-emergence and early post-emergence control of many broadleaf weeds as well as annual and perennial grasses. It is labeled for use in a wide range of agricultural crops and non-cropland areas, helping reduce weed competition during critical crop establishment periods. When applied prior to weed emergence or shortly after emergence, Diuron 4L controls weeds while they are still in a weak seedling stage. With adequate moisture for activation, it delivers extended residual control, allowing crops to establish and compete more effectively. In non-cropland areas, Diuron 4L provides non-selective vegetation control. Diuron 4L is non-corrosive to equipment, non-flammable, and compatible with ground, aerial, and chemigation application methods when used according to label directions.
