Gordons Ornamec 170 Grass Herbicide is safe only on tall fescue and zoysia turfgrasses as labeled for Bermudagrass suppression. Unfortunately, we do not currently have a product labeled for suppression of Bermudagrass that is also safe for buffalograss. We recommend spot treating the Bermuda with a non-selective herbicide such as Killzall and then reseeding any bare spots.
