  • Applications

    Flupyrsulfuron-methyl sodium (CAS 144740-54-5) is a sulfonylurea herbicide with selective systemic action, used in agriculture to control weeds by inhibiting the ALS enzyme. Typical applications include selective weed control in cereal crops (for example wheat and barley); weed management in fruit and ornamental cropping systems; weed control in turf and sports turf settings (lawns and golf courses); and integration into comprehensive weed-management programs (IPM) to reduce resistance pressure and optimize application rates. The sodium salt form is commonly used to improve water solubility and spray performance, subject to local regulations and formulation limits.
