It's unrealistic to expect anyone to ID a grass based on a general
description and not even a picture. Take a sample of what you have to
the Rugers County Agricultural Extension Service. If it's a grass,
unless you use one of the specific herbicides that are effective
against some types, you're wasting your time. And as Peter pointed
out, for some grasses, there aren't any selective herbicides for turf.
