Dismiss will not control Bahiagrass in St. Augustine. St. Augustine is very fragile so it is very difficult to control Bahiagrass in it. Blade is labeled for use in St. Augustine but there are some conditions for this application. The grass needs to be well established and healthy and you cannot spray when it is over 85 degrees. You should use a ½ ounce rate per acre of Dyneamic Surfactant with the Blade, and a second application 4 weeks later if the Bahia is still growing. Blade can stunt St. Augustine if the grass is not strong, so adding a good foliar fertilizer with the application is good to do. Coron 28-0-0 + Turf Nectar well help the St. Augustine grass overcome this.
