I know this is an old thread. But I read through the old ones and I wanted to know how much luck or control and with what products anybody has used for the removal or suppression of Bermuda grass. I am in the transition zone and have cool season lawns with bermuda grass in them because of the warm summers. What chemicals have you used? When were they applied? (During transition?, spring,summer or fall?, what rate?, How often apart was it applied? what kind of control? How many seasons without it reappearing?.) I know these are alot of questions but I feel that anyone with this problem can benefit from your expertise. I have tried Round-up in late summer 3 apps. two weeks apart and have had no luck. And yes I do have a license!!!
