Quali-Pro Quinclorac 1.5 L is a selective post-emergent herbicide designed to control a broad spectrum of annual and perennial grassy and broadleaf weeds in commercial turfgrass, golf courses, athletic fields, and sod farms. Its active ingredient, Quinclorac (17.79%), works by inhibiting weed growth through synthetic auxin disruption, effectively killing targeted weeds while remaining safe for many desirable turf species.
