  • Applications

    Imazosulfuron (CAS 122548-33-8) is a selective herbicide in the sulfonylurea family used in agriculture to control grasses and some broadleaf weeds in crop systems. It is typically applied post-emergence as part of integrated weed management programs, often formulated as tank mixes with adjuvants for cereals and other row crops. The mode of action is inhibition of acetolactate synthase (ALS), blocking the synthesis of branched-chain amino acids essential for weed growth. Its use is subject to local regulations and formulation limits.
