Will Hi-Yield Postemergence herbicide stop Bahiagrass from seeding in a yard with Centipede and St. Augustine?


Hi-Yield Grass Killer Post-Emergence Herbicide is intended to kill grassy plants and is not labeled for use in desirable turf. This is also a post-emergent, rather than a pre-emergent, so it will not prevent new seed germination. The three grasses you have listed are all warm-season grasses, so any product that would affect seeding of one would affect all of them. You could use a non-selective herbicide such as RoundUp QuickPro to spot treat areas where you want to eliminate the bahiagrass and then reseed after two weeks.
