  • Applications

    Linuron (CAS 330-55-2) is a phenylurea herbicide used in agriculture to control broadleaf and grassy weeds in sensitive crops such as lettuce, carrots, potatoes, sugar beets, and other vegetables; it is typically applied pre-emergence or early post-emergence to minimize weed competition and improve crop performance; common formulations include emulsifiable concentrates (EC), granules, and suspension concentrates (SC) designed for soil or pre-plant applications; Linuron is commonly incorporated into crop protection programs and is subject to local regulations and label provisions.
