Will Q4 Plus Turf Herbicide harm a St.Augustine lawn?
The Q4 Plus Turf Herbicide product label states that it should not be applied to St. Augustine grass, so it is likely that it would be harmful to that type of grass. If you can tell us what type of weed(s) you need to treat, we will be happy to recommend a product to use that would be safe to apply to St. Augustine grass.
