Tag Autor is very effective on sedges in turfgrass and also kills annual and perennial sedges, cool season grasses (Poa annua, Poa trivialis, tall fescue). It also controls broadleaf weeds that are in established, warm season, perennial grasses including bermudagrass, St. Augustinegrass and zoysiagrass, centipede, and kikuyu grass. It can be used to remove tall fescue and sedges from warm season & turfgrasses and Kentucky bluegrass.
