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.

Promise made. Promise kept.
Excellent! I could see a significant difference in days and the results are now awesome: even skin, fewer wrinkles (not that I had many, but that was a pleasant surprise 😄) and a slight glow (not sure why). Three drops of the hyaluronic, three or the niacinamide and two of the caffeine (one per eye) and you're done. Recommendation: follow the suggested order for layering them. I do caffeine, niacinamide then hyaluronic. Bonus: They go one smoothly and are light. I used to use mostly L'Oréal, but this stuff is much lighter and smoother. Best bonus of all: a friend noticed the improvement in my skin and he switched as well. Trust me: there's nothing ordinary about The Ordinary.

Staple in my skin care
I buy these over and over. I used to get these from ULTA- however, having them shipped to my door is not only more convenient but also saves me money from wandering around ULTA LOL. Initially, I loved how light weight these serums are. The application was easy and smooth. My skin felt so hydrated after all three AND i noticed my face evening out in color! I am almost out of these three- and about to order them again.

Best Skincare Set — My Second Time Buying & Still Obsessed!
This is truly the best skincare set I’ve ever used! This is my second time purchasing it, and I’ll definitely continue using it. My skin feels smoother, more hydrated, and just healthier overall every time I use these products. The formulas are gentle yet effective, and everything works so well together as a routine. I love that the set is high‑quality, consistent, and gives visible results. It’s become a staple in my skincare lineup, and I honestly don’t want to be without it now. Highly recommend — especially if you’re looking for a reliable set that actually delivers!

Nothing ordinary about it…
I bought this for my 14 year old niece for Christmas and it was a big hit. Apparently The Ordinary is on all of my nieces’ Amazon wish lists, and I have no shortage of nieces. I see it pop up every time I check their lists for birthdays, Christmas, graduations, and every other buying holiday in between. When you’re a teenager, having clear, fresh looking skin is basically a top priority, and she was really excited to start using these. She’s been experimenting with different skincare lately, and so far this is the only brand that hasn’t caused her to break out, which is a pretty big win at 14. She said it feels light on the skin and leaves her face feeling clean and hydrated without being heavy or sticky. And honestly, there’s nothing ordinary about this stuff except the name. It’s a great little starter set for someone getting into skincare, and judging by the reaction I got when she opened it, it also earned me favorite aunt status, which I’ll gladly take.
