What does Quinclorac primarily control in turfgrass?

Quinclorac is a selective herbicide primarily effective against certain annual grassy weeds and some annual broadleaf weeds in turfgrass. It is particularly known for controlling specific grass species like crabgrass and foxtail, making it an important option for maintaining healthy turf by managing these problem weeds.

By targeting annual grasses, Quinclorac helps turf managers effectively reduce competition from these unwanted species without harming established perennials or desired turfgrass species. The herbicide works by interfering with the growth and development of the targeted plants.

While it may have some activity against a few annual broadleaf weeds, its main strength lies in its effectiveness against annual grasses, which is crucial during the growing season when these weeds can proliferate quickly. Understanding this aspect of Quinclorac is essential for turfgrass management professionals aiming to maintain optimal quality and health of cool-season turf.
