Sorry to say that I cannot give it even one star. (but seems I have to)
Mixed it according directions for one gallon and used a tank sprayer. Since I had ordered it I "saved" an area along fence line as a teat--may have well cut it down with weed eater. Sprayed the mix and after a week called and was told it take 10 to two weeks for it to work. Three weeks later, weeds are standing tall--no effect at all. Sprayed again and weeds say "good morning" when I go out. Weeds are a mixture of dichondra, dollar weed and various broad leaf weeds.
Applied to centipede lawn to get rid of weeds. Got rid of the weeds perfect but yellowed out and killed half the grass yellowing first then browning out and dieing. Followed directions used appropriate amount I don't know what happened. Only thing I can think is we didn't have rainfall for over a week after application.
