Certainty Herbicide is not labeled for applications to carpetgrass so could injure it but is safe for bermuda. We are unable to find a selective that can be used for poa annua safely in this turf. You can use Dimension 2EW for pre emergent prevention of poa annua and spot treat actively growing poa with a non selective herbicide and reseed/sod the bermuda.
