Unfortunately, Hi-Yield 2, 4-D Selective Weed Killer is not labeled for St. Augustine. In fact, according to the product label, it can cause injury to this type of grass. This product also does not state that bahiagrass is tolerant, so we cannot recommend that you use it on this grass species. Depending on the weeds you are targeting, you can look at using a product like Ferti-lome Weed Free Zone.
