Quintessential Crabgrass Control

Quintessential™ with H-Value™ Technology takes quinclorac performance to the next level and is an excellent choice if you are going after crabgrass that has invaded your lawn. This is a selective, post-emergent herbicide that can be safely applied to many types of turf to control a variety of broadleaf and grassy weeds including crabgrass, foxtail, signal grass, and torpedo grass.

• 7.5 oz bottle covers up to 5,000 sq ft
• Up to 90-day control for both broadleaf and grassy weeds
• Active Ingredients is Dimethylamine salt of Quinclorac 18.92%
• Unique, patent-pending formulation powered by H-Value Technology, a proprietary performance additive that increases efficacy
• Great for controlling crabgrass, including the mid-tiller stage of growth

Product Description:

Quintessential alters the formulation of quinclorac in a way that improves the 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. 

This product can be applied to both residential and non-residential turf. Selective control means it doesn’t harm turf. Quintessential can be applied from seven days prior to seeding and up to twenty-eight days after selected weeds have emerged. The use of methylated seed oil, such as Duo Stick Select is recommended to enhance the effectiveness of the product. If you cannot get methylated seed oil, a non-ionic surfactant can be used.

Target pests Barnyardgrass, Black medic, Foxtails, Clover, Crabgrass (large & smooth), Daisy, Dandelion, Morningglory, Wild Violet, and more.
