Unfortunately, Halo 75WDG Select Herbicide is not labeled to help control poa annua. In cool season turfgrasses, you are limited to spot treating with a non-selective, like Roundup, and reseeding because poa annua is technically a cool season grass like Fescue. We recommend reading over our guide on How To Kill Poa Annua Grass for further tips and info.
