Negate 37WG is not labeled for Fescue but does great for poa annua in Bermuda. Because poa annua and Fescue are so closely related, there are few products that will kill the poa annua without also harming the Fescue. The only one we are currently aware of is called Prograss and it is very expensive. Your other options would be to either spot-treat with a Roundup-type product and then reseed with the Fescue in those areas, or you can use a pre-emergent like Prodiamine 65 WDG in the fall to prevent the poa from growing in the first place.

Negate 37WG Herbicide is not labeled for cool season turf therefore would damage your Kentucky Bluegrass.
Since poa annua and cool-season grasses are so closely related, there are few products that will kill the poa annua without also harming the lawn. The only one we are currently aware of is called Prograss which can kill & prevent poa and can be applied at seeding, however, it can only be applied to residential lawns by licensed applicators. You may want to see if a service local to you can provide this chemical treatment to your lawn.
Your only other option would be to spot-treat with a Roundup-type product and then reseed with the desirable grass type in those areas. Using a pre emergent such as Dimension 2EW or Pendulum 2G in the fall and spring when you are not overseeding to help prevent the poa from emerging. Typically a split treatment in the fall will yield to longer and better prevention of the weeds.

Per the new supplemental label, for poa annua, you would use 1.5 oz per Acre. If you are treating an area smaller than 1 Acre, then the manufacturer recommends diluting the entire 1.5 oz bottle in a gallon of water first (not in your sprayer but in a separate container) since there are different sized prills in the concentrate. You would then use 3 oz of your mixed solution in at least 1 gallon of water per 1000 square feet. The remaining initial solution can be stored for 2-4 weeks, just be sure you agitate the solution before mixing and re-applying. You can reapply on your dormant turf after 4 weeks if the target weeds are still present.
