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.

Former celeb makeup artist thinks this is THE best!
Color: Soft Brown, Size: 1 Count (Pack of 1)
I was a pretty successful makeup artist based in NY for many years. I am OBSESSED with eyebrows because even a few millimeters and a different angle can affect the way the entire face looks. Most importantly-I started drawing my eyebrows on in the 1970’s at AGE 12 because I was tired of people asking me “why I plucked my eyebrows” at age 12. I hardly ever had any-so from a very young age I drew them on. Now I am 58-and nothing is more aging than a face with no eyebrows. I won’t even walk my dogs without drawing them on-lol! I am as obsessed with product quality as I was when working my career and at the top of my game, so I try EVERYTHING. I also put my brows on first thing in the morning and do not want them to move or wear off under any conditions-so these relatively new extreme wear products are genius. I have tried ALL the eyebrow “pens” and this is the best. I have almost zero natural brows now, so I draw on each hair with the fine tip (microblade style) in the shape I want. I use two shades, a lighter and a darker because it creates the most real looking optical illusion on my face. I do not have to blend-but a spoolie type thing is attached to the lid if needed. This is the only brand that stays on, never smudges when I work out and even stays on through the night if I wear no makeup and wash my face with a non oil cleanser lightly. (I usually use a cleansing oil and that is the best way to remove this product as well) You can also remove this brow pen with an oil based eye makeup remover (Garnier-but even then it resists removal-genius!) There are about 4 or 5 brow products I think are good enough (out of the 50 plus I have tried in my career) and due to ease of application, shades, fine tip and longest wear-this is holy grail for me.

Good product
Color: Soft Brown, Size: 1 Count (Pack of 1)
I do not buy Cover Girl products, but took a chance on this. I am happy I did. This is a nice eyebrow pencil, for a drugstore brand. It does not have the Cover Girl smell. The color was fine for me. It most certainly does not last 24 hours though. I've no idea why the company is allowed to use that in the name.
