What is this grassy weed?

Asked April 15, 2019, 1:16 PM EDT

Good Afternoon. I was wondering what the grassy weed in the picture is. I have been battling Poa Trivialis, but a few patches look different then my other Poa Triv areas. This grass has purple coloring to it on the sheath. A quick online search has me thinking it could be Fall Panicum or Jungle Rice if it's not Poa Triv. Thanks! Brian

This looks like roughstalk bluegrass (Poa trivialis). It is challenging to deal with since it cannot be controlled effectively by any selective herbicides currently on the market.
