Sorry, another Poa A question

[southern-ct-4]

This is the side of my yard that I don't care too much about, but of course don't want it looking like the pic below either. I swear it wasn't this bad last weekend when I last mowed, otherwise I would have posted much sooner. I happened to look out the window just now and was like 'what the heck?'. I had no idea it was like this.

In any case, what would you guys do in this situation (I'm in southern CT with a mostly kbg yard, but there is some ff and pr throughout)? I'd really rather not nuke the whole area. Should I use start a regiment of Tenacity, Certainty, something else? Should I just glyphosate the poa a patches and see if good kbg fills it in? I'll likely use a pre-m this fall to hopefully stop this in the future.

Thanks for any thoughts/suggestions.

If it is Poa Annua, I would hit it with Tenacity. Tenacity is very effective against Annua. Every ten days.
