Blindside Herbicide WDG is labeled for use on St. Augustine grass, and the label does not exclude any specific cultivars. If there is discoloration after applying Blindside, established turf will generally recover well. As with all herbicides, you should not apply to turf that is under stress from extreme heat, drought, disease, or other similar situations. It is recommended to apply Blindside at temperatures less than 85 degrees.
