If you already have it then what you want is Quinclorac. It expensive but it works. You don't need name brand, any Quinclorac powder will do. I mix 1 TBSP per gallon and it kills the crabgrass dead. You'll see it all turn yellow and die within two weeks. I have bermudagrass it doesn't harm it. If you're putting that down, add in some 2-4D at 1oz/gallon. That kills every broadleaf weed. That's much cheaper than Quinclorac, which usually costs about $65-$70 for a seasons worth. 2-4D is about $20 for a gallon, which yields 16 gallons. One more thing I put in mine is MSM powder which kills ryegrass. I mix all 3 together and spray it about once every 4-6 weeks because my neighbors have a yard of weeds that blow over and it kills every single weed, ryegrass, and crabgrass. I used to work for Scott's back in the day.

I do not think it will kill existing crabgrass. Use a Scott's crab grass pre-emergent early next spring. Once crabgrass takes hold, my understanding is you usually have to spray it or pick it.

This could easily help or kill any random lawn.
I've heard that Spectracide has a good spray-on weed killer that you can use once they have already emerged. I've seen it in Home Depot. Wish I'd used it last year.
It's a pre-emergent. Time to put it down in the spring has to do with soil temps.
It's pretty much when the forsythia at your house or neighbors on same side of street have bloomed and started to fall. If I remember correctly you have about 10-15 days after the forsythia blooms.

Above note is for cool season grasses and not for locations in the South.
For same cool season grasses June is the time to put down insect control.

It's more pre emigrant. Crabgrass is something you really need to pretreatment for with a specific chemical before the soil reaches a certain temperature in the spring. Once is germinated and takes root, it's hard to get rid of.
