Patriot WDG Herbicide is not labeled for use on any home lawns, and it is not labeled to control or suppress zoysiagrass. We recommend you take proper care of your desirable Bermudagrass to help it out-compete any undesirable plants, and you can spot treat any zoysia carefully using a non-selective herbicide such as Killzall.
