Will Oxadiazon SC Herbicide have any impact on the perennial rye used on over-seeded bermuda?

Oxadiazon SC Herbicide should be used only on dormant established Bermuda, St. Augustine, and Zoysia turf grasses. We would not recommend using this herbicide in areas where there is desirable rye or other cool-season grasses, or on new plantings until the turgrass is established.
