Kills Grass NOT weeds
Contrary to what the label says, this will definitely kill your grass. In fact, it was quite effective in killing of the St. Augustine that within just a few days my entire lawn looked like crap. I’ve been flushing the soil with water everyday to try to get it out. Now on top of that the lawn has a fungus from the constant watering. A nightmare!

Worked within a few days even with a light rain after application. Waiting to see how long it takes for weeds to fully die off and how long they remain dead.

I would guess that 3/4 of the weeds are still alive. Maybe browned them a little bit but didn’t kill them. I think the spectra side grass and weed killer is better.
