There is not a product that can be used in the home lawn as a selective herbicide. A study from the University of Nebraska details ways to reduce Poa trivialis which allows other grasses to out compete this grassy weed. It also details use of non-selective herbicides and the correct timing for use on this grass, along with reseeding the areas as the rough bluegrass is in decline from use of herbicides in spring. See the following research information: https://turf.unl.edu/turfinfo/5-18_Poa_triv.pdf
The one area that rough bluegrass is not easily managed is where the soil stays wet from poor drainage or from heavy watering.
