Atrazine Screw Up…

I thought I had St. Augustine and applied Atrazine to kill off the weeds. It killed the weeds fine, and only a small amount of grass, nothing I can’t deal with. Now I find out I have Bahia, not St. Augustine!
Everything I have read on Atrazine and Bahia says that post emergence could have some intolerance and is not registered, pre-emergence isn’t registered with no information.
So what do I do now? I wanted to re-seed the lawn and now that I know I have Bahia, I want to use Bahia seed. What will the Atrazine do to the seed? I applied it about 10 days ago. How long should I wait? Am I totally screwed? Please help!

The atrizine will do the same thing to your your new grass sprouts that it does, as it’s designed to do, to new weed sprouts…kill them. Wait a year, without using any weed killer, and try again.

If I remember correctly, doesn’t Atrizine persist in the soil for longer than a year? I have heard stories about farms being turned into housing developements and Atrizine being an issue with new lawns.
I would not want to wait a year and see what happens. I would treat the lawn with activated charcoal and try to nutilize the Atrizine.
Good Luck………..
