Keith from Tampa, Fl writes

Can I broadcast spray my entire St. Augustine lawn with Tenacity Herbicide or should I only spot-treat?

Answer:

Tenacity Herbicide is labeled for use on St. Augustine grass that is grown for sod only, not for use on residential St. Augustine lawns. Hi-Yield Atrazine Weed Killer is a pre- and post-emergent herbicide that can be used on St. Augustine lawns for a wide variety of weeds.
