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.
