It doesn't work, by the way. I mean, it's obviously toxic to the bahiagrass, but it doesn't kill it--just stunts the growth a little. I need something more powerful. Google says I should try sethoxydim, which kills it a little better but is poisonous to just about every grass. In fact it's sold as grass killer--but it doesn't kill centipede. Fortunately my yard is mostly centipede. I really don't like centipede by the way. It's the weakest growing grass there is. Supposedly it's good for drought and shade but the roots are so shallow in clay soil that it's a really poor performer in both, especially under a tree that takes all the water. It also has a yellowish cast to it unless you constantly give it iron.
