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.
