EverPreX is a herbicide containing 83.7% S-metolachlor by weight, formulated as an emulsifiable concentrate. It is designed for preemergence control of various annual grasses and certain broadleaf weeds in a wide range of crops, including corn, soybeans, cereals, vegetables, and more. The product works by inhibiting weed growth shortly after emergence. It can be applied as a preplant, preemergence, or postemergence treatment depending on the specific crop and weed target. Application methods include granular, liquid, or tank-mixed applications. Users should note that S-metolachlor can move through soil via water, potentially impacting non-target areas or groundwater. When handling, technicians must wear protective equipment including long-sleeved shirts, long pants, chemical-resistant gloves (such as barrier laminate or DuPont Viton), and shoes plus socks. Always follow specific rate and dilution instructions for the target crop to avoid crop injury, particularly in sensitive soil types or high-moisture conditions.
