Howdy Dave, The Scotts Bonus S is for use on St. Augustine grass (including Floratam), centipede, zoysia, and carpetgrass lawns only. I wouldn't use it on Bermuda grass.
Bermudagrass is not an easy weed to control, especially when it must be controlled within an already planted turf, garden, or landscaped area. It can be managed by hand with a persistent program of removal, or over large areas by cultivation and by withholding water during the summer to destroy the root systems.
Covering with landscape fabric can also be effective over large areas. Control with herbicides requires careful timing and often more than one application.
Early spring is the best time to apply a grass-selective herbicide. For best control with these herbicides, make the first application in spring when new bermudagrass growth is less than 6 inches in length, then re-apply the herbicide before the regrowth reaches 6 inches again. Additional applications on regrowth may be needed through the spring and summer. It is important to be consistent to win the battle.
