False-green kyllinga (Kyllinga gracillima) has become increasingly problematic in the Mid-Atlantic and Northeast regions over the past several years. I have seen it a little in texas but its not a problem. Our problem weed is Dallas Grass, Paspalum dilatatum . The only way to kill it is with a total kill herbicide, and that will leave dead spots on the lawn. The only true way to get rid of it is to pull it.
