What is this weed in my Bluegrass
I have tried many home center weed killing products to try and kill a weed I have in my lawn, but none truly work. A couple of years ago I mixed a concoction of Weed be gone, Crabgrass killer, and a third by doubling each of the amounts. This killed the weed after 2 applications and also killed much of the grass around it. I still have areas of this grass in existence and my neighbors are filled with it and I am always fighting it back. I have some patches, some areas where it is sparse now, and other areas where it is nicely spread everywhere. I have a picture so I can get help to identify so I can find the correct way to kill it. It is lighter green than my Kentucky Bluegrass. It grows taller and has a wider blade. It has a good root systems and branches off.
I think this may be Bermuda Grass, but not just sure yet as my area doesn't seem to be susceptible to that based on a recent map I saw.
