Bonus S which contains the herbicide atrazine will only control broadleaf weeds, not sedges (nutgrass) or true grasses. To control sedges an effective product is Sedgehammer (with halosulfuron). To control sedges in an established warm-season turfgrass (bermudagrass, centipedegrass, seashore paspalum, St. Augustinegrass, or zoysiagrass but NOT bahiagrass) Image (with imazaquin) is also a suitable option. For control of grasses your options are very limited and depend on what type of turfgrass you are growing.

Floratine St. Augustinegrass (if it is really Floratine) is more like Bitterblue. Both are a little more sensitive to atrazine than Floratam and can show gray leaf spot disease (which in a lawn is mostly cosmetic) after atrazine application and in response to heavy nitrogen fertilization. Otherwise your options are similar. Any St. Augustinegrass if it receives sufficient water, nitrogen fertilizer, sunlight, and regular mowing, can outgrow most kinds of weeds.
