  • Applications

    Oxyfluorfen (CAS 42874-03-3) is used as a selective soil-applied herbicide in agriculture and horticulture, providing pre- and post-emergence control of certain grass and broadleaf weeds. Common applications include weed control in agricultural crops such as vegetables and other field crops, in ornamentals and greenhouse/nursery production, and in turf and landscape management. Use is subject to local regulations and formulation limits.
