Edgeless® Concentrate is a turf growth regulator designed for the regulation of perennial turfgrasses. It contains two active ingredients: clethodim (13.2%) and imazamox (5.0%). This product is used to manage turf growth by inhibiting gibberellic acid (GA) biosynthesis, which results in more compact, denser growth and reduced trimming requirements. It is intended for use on specific turfgrass species including Cool-Season Turfgrasses (Kentucky Bluegrass, Perennial Ryegrass, Tall Fescue) and Warm-Season Turfgrasses (Hybrid Bermudagrass, Common Bermudagrass, Seashore Paspalum, St. Augustinegrass, Zoysiagrass). Application is performed via spray application, typically using a single nozzle sprayer with a 6-inch band. The product should be applied when turf is actively growing. Users must calibrate equipment to ensure correct rates per linear foot. Handling requires caution: it is harmful if swallowed and can cause substantial or temporary eye injury. Always wear appropriate PPE, including long-sleeved shirts, long pants, shoes, socks, and chemical-resistant gloves. Do not apply to surfaces where water runoff can reach sensitive areas or water bodies. Do not use with chemigation or through irrigation systems. Always read the full label for specific application rates and safety instructions.
