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.

No No No
I had the worst nightmare using the APLB Tranexamic Acid Niacinamide Lotion. I used this product consistently for about three weeks, hoping it would help with brightening and hyperpigmentation, but instead it completely damaged my skin barrier. What started as mild irritation quickly turned into severe itching, redness, inflamed bumps, and intense skin sensitivity. Eventually, my skin developed dermatitis-like symptoms with painful inflammation, red rashes, and even slight bleeding in certain areas from constant irritation and scratching. Instead of improving, this lotion made my skin look worse — angry, inflamed, textured, and extremely reactive. The itching was unbearable, and the red bumps took a long time to calm down. If you have sensitive skin or are prone to eczema, contact dermatitis, or allergic reactions, please patch test very carefully before using this product. My experience was honestly terrible, and recovering my skin afterward took much longer than the three weeks I spent using it. (Still recovering after 2 months)

Just started using it
The scent is ok but I do notice that it takes a while to rub into my skin. I just started using it but will update later if it’s actually working.

Wow! So moisturizing!
OMGosh, this feels so good on your lips! I just got this today so I’ll have to update if the moisture doesn’t last. But so far it feels nice. I did have a slight issue with it melting onto itself in the one day it took to get to me. See photos. The tube itself was slightly concave because of the melting. But is still intact. So far though I love this stuff!

Pretty good stuff
Not a miracle cream, but I've certainly paid more for worse lip balm. The tallow is helping keep my lips hydrated, and it feels great when applied. Just got Invisalign, and I struggle with hydration normally, but this is helping keep the lips soft and smooth, and is miles ahead of the cheap drugstore brands that dry more than they help.
