Just wanted to see if there is any better chemicals to use
on crabgrass than drive. i have also tried q4 but it just seems
to not kill it off.

All post products I use stop the annuals from seeding out, not totally getting rid of them.

Barricade, Simazine, Prodiamine are all pre-emergents which are of no help this time of year. Drive which is Quinclorac is the same thing that is in Q4. Q4 contains other brodleaf herbicides along with Methylated Seed Oil. When using Drive you must use MSO, not a standard spreader sticker. Results are much better. I have killed crabgrass with Drive.
