I bought this herbicide because the label says it can be used to kill or suppress Bermudagrass in a Zoysia lawn. I have this problem in my lawn in Central Florida. I spot applied Ornamec 170 about 3-4 weeks ago, and put on another application after two weeks. The label states that the treatment may take one to two growing seasons to completely eradicate the problem.
At this point I can state that Ornamec is certainly suppressing the Bermudagrass, and it effects the Zoysia as well but not as severely. I believe the turf will survive and the Bermudagrass will die, but do not know how long this will take. I will revise this review or add another one in the Fall when I know more.
