Mode of Action
Quinclorac 1.5L Select is an auxin agonist and is classified as a quinoline carboxylic acid. It is absorbed by foliage and roots and translocated throughout the plant. The control symptoms exhibited by broadleaf weeds include leaf and stem curl or twisting, and chlorosis. Susceptible grasses demonstrate stunting, chlorosis, and gradual reddening followed by necrosis and death. Apply Quinclorac 1.5L Select to actively growing weeds as post-emergence broadcast or spot sprays using the turf species, rate and growth stages indicated on the lab.
The use of Quinclorac 1.5L Select before or after seeding or overseeding a turf area will not significantly interfere with the turf grass seed germination and growth of those grass types identified as tolerant or moderately tolerant on the label.

CrabGrass doesn't stand a chance. Saves your Gr-ass.
By Paul in Loganville on 07/25/2017
After failing miserably with name brand products from local retailers, I watched a DoMyOwn video on Youtube to see what to use on crabgrass. I landed on Quinclorac concentrate in an easy-to-use liquid dispenser. I ordered and paid online and was lucky enough to live 18 miles from the warehouse where the package was waiting for me when I arrived 30 minutes later. This stuff needs a surfactant to stop the water from beading up, so add that to your purchase.
