Product Description

Quinclorac 1.5L Select™ is a selective, post-emergent herbicide that can be applied to many types of turf, both residential and non-residential, to control a variety of weeds. Quinclorac 1.5L Select™ can be applied from 7 days before seeding and up to 28 days after emergence on selected weeds. 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-emergent broadcast or spot sprays using the turf species, rate and growth stages indicated on the label. The use of Quinclorac 1.5L Select™ before or after seeding or overseeding a turf area will not significantly interfere with the turfgrass seed germination and growth of those grass types identified as tolerant or moderately tolerant on the label.

Customers are mixed about the effect of the herbal supplement on crabgrass. Some mention that it not only kills crabgrass, but also Lespedeza which likes to grow in Bermuda. They say it's great for killing post-emergent crabgrass and torpedo grass. However, some say that it has not killed the crabgrass or that it killed all their grass in just few days.

Updated Review - Crabgrass Killer
I applied this per the instructions. Used the proper methylated seed oil. It went on a little heavy. It may have killed some weeds, hard to tell. But the crabgrass is still there.I tried a second application with what I still had left, and unfortunately it rained the next day, so no clue if it would have worked.-Changed review to 4 stars. It took a while, but it definitely worked. This is my lawn about a month later. Most of the crabgrass is dead.
