Pre.emergent to kill seeds good. But the existing grass needs to be eliminated.
Dug out.or spot treat with round.up while still actively growing.

Yuck!! I may need 650 gallons of round up! It is sure actively growing....

Bonide and Hy-Yield are two brands that pop into my head off-hand.
Go to a Garden store, Farm store or hardware store as they should have some brand in stock.
If you have one I would start with the farm store.
Before you apply cut your grass as short as your lawn mower will allow it will work better usually, at least it has for me.
Crab grass is annual so getting the seeds onto the ground where the killer/preventer can hit them is better than if they are dangling in the air on a branch but they sprout as long as their is war weather.

The best way to control crabgrass is to mow your lawn a little higher and water less often but more deeply. The herbicide most often used as a pre-emergent against crabgrass is Pendimethain. One of the more common brand names is Scott's Halts Crabgrass Preventer.
Barbalee said:Thank you, Sue! I'd just as soon go with the pre-emergent. I've waited this long that I might as well wait to use pre-emergent and see if the terrible stuff comes back!

Thanks, Kent! Yes, we get sub-freezing, but what I'm reading here tells me the roots will still be growing underground. Not so?? That's what this thread says, but I thought it would be gone after winter and I'd just have to be ready with pre-emergent. Now I'm totally not sure what to do!
