Jason from Atlanta Georgia writes

Can I use this on dormant St Augustine grass to kill winter ryegrass?

Answer:

While it is safe to apply Hi-Yield Atrazine Weed Killer to fully dormant St.Augustine grass, it is not labeled to control rye grass. Sertay Herbicide (Generic Certainty can be used to control perennial ryegrass.
