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.

Only for the pale skinned ones
Style: SPF 50, Size: 3 Fl Oz (Pack of 1)
Great coverage and texture! However, it left a white cast over olive toned skin. I looked sick. But looked perfect on my pasty redhead daughter.

Great everyday sunscreen
Style: SPF 50, Size: 3 Fl Oz (Pack of 1), Style: SPF 50, Size: 3 Fl Oz (Pack of 1)
Really impressed with this sunscreen. It’s a bit thick going on, but a little goes a long way. Once applied, it feels lightweight, not greasy or oily at all. Provides great coverage and protection, definitely a great product I’ll keep using.

The BEST sunscreen I've found
Style: SPF 50, Size: 3 Fl Oz (Pack of 1)
This is my MUST HAVE sunscreen. I've had almost every type of skin cancer (thankfully, caught early), so I NEED good sun protection, especially on my face. I have very fair skin. This product leaves a bit of a white cast, but after a short period of time, that white case is absorbed. The white cast of a mineral sunscreen might look chalky on a person with darker skin. The BEST thing about this sunscreen is I can put it on my eyelids and under my eyes, it doesn't irritate my eyes AT ALL. The other well-known sunscreen I used for a long time really made my eyes sting if a bit got into them. This is my favorite sunscreen of all time.

Solid mineral SPF with light coverage effect
Style: SPF 50, Size: 3 Fl Oz (Pack of 1)
I’m used to La Roche-Posay’s chemical sunscreens, so this was my first time trying their mineral version. The texture is actually quite nice for a mineral formula. It spreads evenly and doesn’t feel gritty or chalky. That said, it does take a bit longer to fully absorb compared to chemical SPFs. I’m already very pale, and I still notice a slight white cast. It’s not extreme, but it’s there. To be fair, most mineral sunscreens tend to do this, especially those using zinc oxide and titanium dioxide. Interestingly, on my skin it almost behaves like a very light tinted sunscreen. It slightly blurs and softens the appearance of minor blemishes and redness, which I appreciate on minimal-makeup days. It provides broad-spectrum SPF 50 protection and feels gentle on sensitive skin. I haven’t experienced irritation, pilling, or breakouts. It layers reasonably well over moisturizer but benefits from being applied in thin, well-blended layers, which adds some time to my morning routine so it's a little inconvenient. Overall, it’s a solid mineral option with good protection. Just expect a bit more blending time and a subtle cast.

Great for pregnancy (or regular use)
Style: SPF 50, Size: 4.05 Fl Oz (Pack of 1)
I searched far and wide for a safe mineral-based sunscreen for pregnancy. I settled on this one and I was not disappointed. It saved my skin from a lot of sunburn this summer! As other reviewers mentioned, it is harder to rub into the skin and can leave a whiteish tint, but that’s a small price to pay for a pregnancy-safe option.
