Rimsulfuron 25DF is not labeled to be used on St Augustine grass specifically, only warm-season turf such as Bermudagrass, zoysia, and centipede. We would not recommend using this product on St Augustine grass. You could test a small area first for tolerance, but we cannot guarantee that it would not damage the turf. Keep in mind that this product is not for use on residential turfgrass. If you would like to tell us what weeds you are targeting, then we can recommend an alternate product for you.
