Proxy is a Type II plant growth regulator that can be used in cool-season turf for growth regulation of desirable grasses and provides seedhead suppression of both Annual Bluegrass (Poa annua) and White Cover. As a plant growth regulator, Proxy promotes lateral growth while limiting top growth, which leads to denser, tighter-knit turf and improves playability when used as directed. By reducing seedheads, Proxy also aids in Poa management programs by reducing flowering during the Spring flush, which may gradually lower the seed bank in the soil.
