Pedro from The Woodland, Tx writes

Which is better spectracide weed stop for lawns with Atrazine or Weed Stop for lawns crabgrass killer?

Which one of these is the best grab grass killer but will not harm my saint Augustine grass. Thank you

Answer:

Hi-Yield Atrazine Weed Killer would be the product to use on St Augustine.  Spectracide Weed Stop for Lawns Plus Crabgrass Killer Concentrate states Do not apply to St Augustine on the product label.  It contains Quinclorac which St Augustine is not tolerable to.
