Now if the Prowl doesn't prevent the crabgrass and it emerges it is harder to kill. Commercial lawn crabgrass killers are expensive and the active ingredient is usually Mesotrione which is Callisto. Again generic Callisto isn't labeled for lawns but word on the street is that some people have used 5-6 oz. per acre to kill crabgrass but is a slow kill that takes up to 2 weeks......
