Quintessential Quinclorac Herbicide for Crabgrass and Turf Weeds - 7.5 Oz.

Prime Source


Quintessential with H-Value Technology alters the formulation of quinclorac in a way that improves absorption of the product into the plant. That means faster activity and higher rate load in the targeted weed, as well as improved performance in drought stress or rainfast situations. And unlike any other herbicide on the market, Quintessential demonstrates improved control of crabgrass at all growth stages, including the problematic 3-5 tiller stage. Quintessential will be the essential tool for combatting crabgrass and other troublesome turf weeds.

Key Benefits:

  • Controls crabgrass including the mid-tiller stage of growth
  • Unique, patent-pending formulation powered by H-Value Technology, a proprietary performance additive that increases efficacy
  • Enhanced drought stress and rainfast performance
  • Enhanced absorption by foliage and roots and transported throughout the plant
  • Stunted grasses exhibit chlorosis, gradual reddening, and necrosis followed by death

*HomeandGardenSupply.com always recommends reading the entire product label before use, and following all necessary safety precautions, mixing instructions and proper application methods.

    Good grassy week control

    It works well on grassy as well as some broad leafs as well. I think it would work quicker if I had ordered and used Metholated Seed Oil as a surfactant. I used dish soap, which is really not advised. I also used laundry detergent in another application which seems to make the product stick better on the grassy weeds. Crab grass is slowly turning brown and drying. Some crab grass that I hit hard is fried.
