I have used another product or two (I'd have to go out to the garage and find the bottles to say which ones) -- but haven't had much success. I was hoping the Ornamec would do the trick. Dennis -- I'm sorry to hear it didn't work well for you. I've got a couple of 8-foot sections along the fence that are seriously infested with Bermuda. I wouldn't be surprised if those roots were six feet down, and very very thick. I'll have to do some serious digging for sure -- was hoping to use the Ornamec ahead of digging, and as follow-up treatment.
