Used as a selective pre-emergence and post-emergence herbicide in agriculture, Diuron solution controls broadleaf weeds and grasses in crops such as cotton, coffee, sugarcane, and citrus. It is effective in industrial settings for weed control on non-crop lands, railways, and roadways. Commonly applied to soil, it inhibits photosynthesis in target plants, providing long-lasting residual control. Due to its persistence, it is often used in areas where infrequent reapplication is needed. Also utilized in algae control in irrigation systems and water reservoirs.
