Used as a selective herbicide in agriculture, particularly in forestry and non-crop areas. Controls a broad spectrum of annual and perennial broadleaf weeds and some grasses. Commonly applied in pine plantations, rangeland, and industrial sites due to its effectiveness at low application rates. It works by inhibiting the enzyme acetolactate synthase (ALS), disrupting plant amino acid synthesis. Due to its residual activity in soil, it provides long-term weed control but requires careful use to avoid carryover to sensitive crops.
