Annual bluegrass (Poa annua). LINK It will die in the heat of summer. You can try atrazine + surfactant by itself (not the cocktail mixture) but it likely won’t be that effective b/c of the maturity of those plants and some degree of herbicide resistance of Poa to the herbicide.
The key to “eliminating” it going forward is to to apply pre-emergent herbicide, like Prodiamine or Dimension (dithiopyr), in Fall (mid-Sept/mid-Oct).
