This product is formulated as a suspension concentrate (SC) and can be applied as an early preplant, preplant incorporated, preplant surface, or preemergence herbicide. It is also suitable for postemergence applications in certain scenarios. The herbicide is effective against a variety of annual and perennial grasses and broadleaf weeds. When using this product, technicians must be aware of significant environmental risks, including potential groundwater contamination and runoff into surface water, particularly in areas with sandy soils or shallow water tables. Users must follow specific engineering controls, such as using enclosed cockpit mixers and loaders, and must adhere to strict PPE requirements to prevent skin, eye, or respiratory irritation.
