  • Applications

    Alachlor (CAS 15972-60-8) is a chloroacetanilide herbicide used in agriculture to control weeds pre-emergence; it is applied in crops such as corn, soybeans, and peanuts; formulations commonly include granular or emulsifiable concentrate products; it is typically used as a selective soil-applied herbicide within integrated weed-management programs; its role is to provide early-season weed control for crops while mitigating competition, subject to local regulations and formulation limits.
