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.
