While Grass Out Max (Clethodim Herbicide) is labeled to control poa, it is also labeled to control your cool season lawn such as the kentucky. Unfortunately there is no selective herbicide to remove the poa from a cool season lawn. You will need to spot treat it with a non-selective such as Roundup QuikPRO - 5 x 1.5 oz. packs & reseed those areas. You could also use a pre-emergent such as Pendulum 2G Granular Herbicide in the fall to try & prevent it
