it’s a weed killer, lots of different names. Best place to buy it though is agri supply, best price in town, they have a large display of it. Get the amine kind and get a gallon, depending on the size of your yard may last a season or two. Will kill weeds in all grasses, centipede can be a bit touchy with it but I’ve used it on everything in all types of grasses. If there is a cotton field near you though be careful, it will wilt cotton. I have 4 acres and I spray the stuff with a boom sprayer.
The bottle says to not use amine on bermuda. I am in a new house and my lawn is all bermuda and I am worried about ruining it. Have you used it on bermuda?
