As with most fungicides, insecticides and herbicides such as TZone SE Herbicide, keep children and pets out of the area during the application and once the area is completely dry (anywhere from 1 - 4 hours), then they can re-enter the area.
Please view the full product label for more information.
According to the product label, the TZone SE Herbicide can be used for sericea lespedeza. Unfortunately, we are unsure if it is safe to use on native grasses. We encourage you to contact the manufacturer for more specifics on your native grasses. You may reach PBI Gordon at (816) 421-4070.
