  • Applications

    Flucarbazone-sodium (CAS 181274-17-9) is used as an active ingredient in herbicide products for selective weed control in cereals. It is a sulfonylurea herbicide that inhibits acetolactate synthase (ALS), enabling post-emergence control of actively growing weeds with limited crop injury when applied according to the label. The sodium salt form improves water solubility, supporting formulation and spray preparation for agricultural use. It is commonly employed within integrated weed management programs and can be tank-mixed with other herbicides or adjuvants to broaden spectrum and help manage resistance, subject to local regulations and formulation limits.
