Prograss is an emulsifiable concentrate herbicide containing 19% active ingredient, Ethofumesate. It is classified as a Group B herbicide and is designed for use on various turfgrasses, including perennial ryegrass, Kentucky bluegrass, creeping bentgrass, turf-type tall fescue, St. Augustine grass, and dormant bermudagrass. It is used to control annual and perennial grasses such as crabgrass, large crabgrass, smooth crabgrass, ryegrass, green foxtail, nut sedge, and kyllinga. The product is intended for outdoor use on commercial sod farms in Arizona and non-commercial applications on lawns, farms, nurseries, or greenhouses. Application timing varies by turf type and target pest, often involving spring or fall applications. Handling requires strict adherence to Personal Protective Equipment (PPE) guidelines, including chemical-resistant gloves, protective eyewear, and long-sleeved shirts/pants. Users must avoid contact with eyes and skin; if contact occurs, rinse immediately with water. The label notes that the product contains petroleum distillates, which may pose an aspiration pneumonia hazard. It is critical to manage spray drift to avoid non-target sites and to follow specific application rates to prevent turf injury or resistance development.
