Will this QuickSilver Herbicide kill Prostrate Knotweed?

I have been fighting with Prostrate Knotweed in my lawn for 2 years now and its starting to take over and invade my gardens which I is bad. I need to kill this weed, but most things I've tried it just laughs at.


Yes, QuickSilver Herbicide will control Prostrate Knotweed. The QuickSilver Herbicide product label recommends applying QuickSilver Herbicide at rates of 1 to 2 fluid ounces per acre, or 0.023 to 0.048 fluid ounces per 1,000 square feet.
