Unfortunately there is a not a good selective product that you can use to get rid of the dallisgrass without killing the surrounding grass, too. Your best options once it has emerged is to either spot spray or wipe on something like Round Up, or hand dig up the clumps of dallisgrass down to the root system and re-seed with the fescue. You could use a pre-emergent such as Dimension 2EW in the Spring and Fall to help prevent it from ever growing.
