Hi - Yield Atrazine Weed Killer RTU is labeled to control poa annua for both emerged weeds and weeds from seed in St. Augustine and Centipedegrass only. It is not labeled for poa trivialis and cannot be used on another types of lawns. Acclaim is an option for Poa Trivialis depending on your turfgrass type.
