I used a Dragon brand post-emergent for a few years that contained a chemical branded 'Trimec' that did a good job in a garden sprayer. Last year I switched to a new Bayer (yes, the same Bayer that makes aspirin) post-emergent concentrate that works incredibly well. I have a tall fescue blend lawn and mixed it to be a bit stronger than recommended and sprayed it on trouble areas. It left the grass completely untouched, but within 3 days all the crabgrass was yellowing. I have had experiences clike Clavus' where a bad mix does bad things to the stuff you want to keep - but this Bayer Advanced 'lawn weed killer' was really user friendly.
