Quintessential™ 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.

  • 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
  • Available in multiple sizes *

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

Great for sensitive skin
This was great to take on vacation. I went to Cancun and used this on my face. Never got burned. I have super sensitive skin and this didn’t cause any reactions. I’m also sensitive to smells and I don’t notice anything with this product. Will purchase again.

Buyer beware!
Awful! I sprayed my face with it and immediately felt my skin burning. I opened the bottle and noticed all that was in it was a yellowish fluid that smelled like straight rubbing alcohol. My face still has marks on it days later from whatever the substance was. I have used this brand before, and never experienced anything like this. The product was either years past expiration, or liquid was replaced with some kind of chemical.

Works well, smells great, goes on easily
Sun protection factor: 15 Sun Protection Factor (SPF), Size: 6 Count (Pack of 2)
It smells good. It goes on easily with the spray bottle. It keeps me from burning while out biking. It's a good price. Overall, a very nice product that does what it should. We carry it in our bike packs and in the car when we know we'll be out in the sun all day. Doesn't feel heavy when sprayed on so it smooths over your skin very well. Keeps me from burning.
