Used as a selective herbicide primarily in agriculture, especially in crops like corn, sugarcane, and certain vegetables. It controls broadleaf weeds and some sedge species by inhibiting the enzyme acetolactate synthase (ALS), which is essential for plant amino acid synthesis. Due to its selectivity and effectiveness at low application rates, it is favored for pre- and post-emergence weed control. It degrades relatively quickly in soil, reducing the risk of carryover to subsequent sensitive crops. Commonly applied in granular or liquid form, it helps manage resistant weed populations when rotated with other herbicides.
