I was told I could use this for crabgrass in my St. Augustine lawn and that it would not hurt the S.t Augustine. Is this true?
Hi-Yield Grass Killer Postemergence Herbicide could harm St. Augustine grasses or other turf. Hi-Yield Atrazine Weed Killer can safely be applied to St. Augustine grass for crabgrass suppresion. Be sure to follow the product label for complete application instructions.
