No such luck. Now I have weeds spread all over the lawn, some of which attach their seeds to our dog every time she goes out (several times a day). In the early summer I bought Weed B Gone for St. Augustine grass and applied it as directed. No obvious change. I applied it again last month. No obvious change. The weeds are thriving. I’m about to use Spectricide Lawn and Weed Killer which will kill everything, and I can lay sod on the dead areas in the spring. But before I take that drastic action, does anyone know of a product that actually works? I think plain water would work as good as Weed B Gone.

Since the pre-emergent didn't work sounds like your weeds are perennial. For St Augustine Provista use glyphosate 41% to kill the weeds. Tractor Supply and Rural King are the only places around here that sell glyphosate. If your lawn is not actively growing then mix the glyphosate at 50% or wait until spring to apply.

Thanks, I do mow my own lawn. I’ve always mulched it but this year I’ve used the bag to minimize seed dispersal.

Pay attention to what the original quoted post said "Roundup for Southern Lawns." It is a variation specifically meant for weed killing, and does not harm St. Augustine grass.

However, Atrazine is a much better choice, and is also safe for St. Augustine grass.
