This is the only weed killer I have found, that kills cat-tails effectively. Not cheap, but worth it.

This killed the bermuda grass... and the plumeria that I was trying to save by killing the bermuda grass. Definitely not as selective as advertised. Didn't seem to hurt my mango tree, so it may be fine near trees.

If I could give a no star I would. Product didn't work. U can't return if open. Product takes up to 2 weeks to kill. I will not ever buy from this company again.

Hi-Yield Grass Killer has done an excellent job of killing the common bermuda in my centipede lawn. It took about two weeks to be totally noticeable, but it is certainly noticeable now. I regret that I waited so long in the summer to apply it. Plan to hit it hard next spring to try and totally eliminate it. I'm sure it has killed some othe unwanted weeds, but I mainly bought it for the common bermuda. This was done through spot treating.

This is the only product I have found that kills grasses that try to take over my iris and asparagus beds that doesn't affect the iris and asparagus. It does take patience as you won't notice the grass dying right away, especially in cooler weather with lows in upper 30's and daytime highs in the mid sixties. I sprayed initially 4 weeks ago with a second application a week later using dormant oil in the mixture. This is the first week that I can see more brown grass than green and it is definitely working on those hard to kill grasses that send runners all over.
