  • Applications

    Dimethachlor (CAS 50563-36-5) is primarily used as a soil-applied pre-emergence herbicide in agricultural crops to control annual grasses and broadleaf weeds. It is commonly formulated as an emulsifiable concentrate or granular product and is applied to the soil before or shortly after planting according to crop guidelines. In practice, it is used as part of weed-management programs in cereals, vegetables, and other row crops, often in tank mixtures with other herbicides or adjuvants to broaden spectrum and enhance efficacy. Its use is subject to local regulations and formulation limits.
