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 Ingredient: 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.

Huron crushes it!
Style: Shampoo & Conditioner Set
I have no idea how other reviews can speak of low lathering and not so manly scent. First, heavy lathering is not a good thing, you want a light lather so as to not remove too much natural oils. And the scent is absolutely phenomenal. A little goes a long way. It is suggested to use a quarter size amount which for me proves to be a bit too much. And the lathering is perfect. The shampoo is amazing and my hair feels as though it was conditioned even though I have not applied the conditioner yet. As for the conditioner, the ingredients are far better than any within a drug store type product. My hair remains soft and fantastically conditioned all day and night. Absolutely outstanding product. Far better than American Crew and other big name brands which immediately went into the trash after my second use of Huron. The scent is totally manly and well done. The menthol is not overwhelming and the citrus comes through very well. Every other brand has a far too powerful tea tree and/or peppermint scent that actually burns my eyes. After my second use I immediately started a subscription at their website usehuron.com. I am looking forward to using their soap bar. I prefer a bar of soap to a body wash. I have finally found my absolute go to shampoo and conditioner. No more purchasing others for comparison. Huron is at a good price point for top tier products. It deserves way more hype when it comes to best products on the market. I am totally sold on Huron.

The Real Deal
Style: Shampoo & Conditioner Set
Fresh, clean and potent. I have probably experimented with 20 shampoo and conditioners over the past 5 years looking for one that does everything I want it to. It's a sparkling mint meets teakwood meets citrus—refreshing without being overpowering. Little goes a long way: a pea-size amount lathers well, and it's left my hair noticeably softer and more manageable over time. This high quality and light but present fragrance have made this worth it for me.
