Pylex Herbicide is not labeled to kill poa in tall fescue. There is not a good method to get rid of this weed once it is actively growing, other than to spot treat with a non selective product like Rounup QuikPRO and over seed in those areas The best way to treat for Poa Annua is by using a pre emergent like Ferti-Lome Broadleaf Weed Control with Gallery in the fall.
