Does Speedzone weed killer kill poa annua?

I have Kentucky bluegrass and I'm having problems controlling poa annua. Is this a good product to use or what Is a good product that you would recommend? Thanks!


No, Speedzone Concentrate is not labeled to kill poa annua. We would recommend using Blindside Herbicide. It is safe to use on your KBG lawn and is labeled to surpress poa annua. You will use 0.075-0.15 per 1000 square feet. You will likely have to do a subsequent treatment.
