John from Eighty Four, Pa writes

Will Tenacity Herbicide kill Poa Annua and leave my rye and blue grass alone?

Answer:

Tenacity Herbicide is not labeled to control Poa Annua/Annual Bluegrass in a post emergent application, it only states that it could cause injury to it if sprayed. Kentucky bluegrass and ryegrass are tolerable to it so would not be harmed.  It is only labeled to be used for suppression of poa annua when used as a pre-emergent.  Unfortantely there is not a post emergent product that would remove it and not harm the KGB as they are too similar.  We recommend that you spot treat the poa annua using a non-selective herbicide such as GlyPhoSel Pro. Your best option for poa annua is to use a pre-emergent herbicide more suited to preventing it like the Prodiamine 65 WDG.
