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.

Transforming Space: A Tale of Two Stunning Room Dividers
Color: Black, Color: Black
The four-panel screen room divider is absolutely stunning! Unfortunately, the first one the FedEx driver delivered ended up at the wrong address. After notifying Amazon, they promptly sent me a “replacement” room divider through UPS, which arrived right on schedule. Now, I find myself with two beautiful dividers! They both enhance the aesthetic of my home. I informed Amazon that my first room divider magically appeared today in my building’s lobby. I’ve placed one of the new screen dividers in front of an old one, and the modern Roundhill divider really makes my older piece look outdated! The Roundhill screen divider is sleek, bold, and refreshing—I’m in love with it. The second divider serves a practical purpose by hiding my bulky grocery cart, fan, and vacuum cleaner. These items used to clutter my living room closet, making it difficult to access due to the abundance of coats I had stuffed in there. Now, all those items are neatly tucked away behind the elegant Roundhill four-panel screen divider, bringing a sense of order to my space. Thanks, Amazon! ♥️ Thanks, Roundhill! ♥️

Beautiful, Sturdy, Well Made, good Value for the money
Color: Black
I don’t know what the bad reviews are about. This is a beautiful, well made 4 panel screen. The screen print appears to be a standard print that is likely the same on every screen they produce (not hand painted by two different people). It is beautiful. Everything about it, including the colors and the screen print image on rice paper, is more lovely than the photos. The wooden frame (black) is solid and sturdy. The hinges are stable and well positioned. When people say lightweight it sounds misleading. It is lightweight enough to easily maneuver but this four panel screen is sturdy and stable. It is slim and tall so someone could conceivably bump into it and jostle it. But no more so than any number of other items in one’s home. I highly recommend this beautiful, lovely, fine piece of home decor. I purchased this as a divider between my work station (office) and my living room. Also, even though there was a slight dent in the package when it was delivered, it wasn’t a deep enough gash to damage the screen. When I pulled the screen from the box my first thought was just how study it is. So very pleased with this purchase.

Beautiful Room Divider
Color: Black
This room divider is so beautiful and elegant yet very functional, study and very well made! I have had many compliments on its beauty and elegance. They have said it is much nicer than blurring my background. Which affects how you look on a teleconferencing meeting. I do zoom meetings at times for my religious meetings when I cannot go in person! And this is exactly what I have needed to obscure my private bedroom space. The size is perfect for my size desk. It covers completely the whole area not showing any of my bedroom to the public. When not in use I fold it up and put it away. It is lightweight and very easy to move around. The height doesn’t make it awkward to move and yet tall enough to obscure my whole background. MORE IMPORTANTLY~NO ASSEMBLY NECESSARY ‼️ You will not be at one moment disappointed by this purchase instead you will love it!💖💕💖

Excellent sport sock!
Size: One Size, Color: (100) White / White / Halo Gray
Molds onto foot, super soft and breathable. A lot of my ankle socks tend to slip or cut off blood circulation. This one literally is a perfect fit. No slip. After playing hours of tennis every week, my feet don't feel sore or bruised. Must buy!
