  • Applications

    Ethofumesate is a soil-applied pre-emergence herbicide used to control annual grasses and some broadleaf weeds in agriculture. Real-world applications include weed control in field crops, root/tuber crops, vegetables (including leafy vegetables), and turf/landscape grasses, with product choices and registrations varying by region. Its use is subject to local regulations and formulation limits, and should adhere to agricultural management and safety guidelines. CAS 26225-79-6.
