Used as a selective herbicide in agriculture, particularly in wheat crops to control a broad spectrum of grass and broadleaf weeds. It works by inhibiting the enzyme acetolactate synthase (ALS), which is essential for branched-chain amino acid synthesis in plants, leading to cessation of cell division and plant growth. Effective at low application rates, it provides post-emergence control and is valued for its soil flexibility and favorable environmental profile. Commonly formulated with safeners to protect the crop while enhancing weed kill.
