Product Description

Powerful Post-Emergent Crabgrass & Weed Killer

LESCO® Quin-Way™ 1.5L is a professional-grade, selective post-emergent herbicide designed to eliminate tough grassy and broadleaf weeds like crabgrass, clover, and dandelion. Whether you're a homeowner maintaining a beautiful lawn or a landscape professional, Quin-Way delivers visible results fast—without harming most desirable turf types.

Why Choose LESCO Quin-Way?

  • Fast, systemic control of crabgrass and dozens of grassy/broadleaf weeds
  • Tank-mix compatible to boost performance with other herbicides
  • Safe to use at seeding or overseeding time on tolerant turf types
  • Trusted by professionals for use on residential, commercial, and sports turf

How It Works

Quin-Way™ contains 18.92% Quinclorac, a Group 4 herbicide that targets weeds at the root. It's absorbed through both leaves and roots and moves systemically throughout the plant, causing growth distortion and eventual death. You'll see twisting, yellowing, and die-off within days.

How to Use

  • Mix 1.45 fl oz per 1,000 sq ft in a sprayer
  • Add methylated seed oil (0.55 fl oz per 1,000 sq ft) to enhance absorption and weed kill
  • Apply post-emergently to actively growing weeds
  • Do not mow 2 days before or after application
  • Do not water for 24 hours after application

Note: Safe for use around seeding of tolerant grasses such as tall fescue, ryegrass, and Kentucky bluegrass. Not for use on St. Augustinegrass, centipedegrass, or desirable clovers.
