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 Ingredients is 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.

These shoes adequately do the job they're meant to do
Size: 11, Color: Black, Size: 11, Color: Black
For shoes to wear daily for work, these are absolutely perfect. I give four stars simply because they are not 100% perfect; that is, they are a reflection of their cost and durability. With that said, these shoes are perfect for my role as a professor AND a person who walks half a mile from the train station to class and back 5x a week. Comfortable. Nice cushion on the heel. And they look really amazing - classy but not pretentious. I bought a second pair a week after the first just so I could have different colors, and it is likely I will get a third pair. For $40-ish dollars, they do the job they're meant to and they do it well. This picture shown are the originals I bought, but I also got the black pair, too.

Comfortable shoes that still look presentable
Size: 12, Color: Black
I wanted a pair of shoes that were more presentable than regular sneakers but did not feel like stiff dress shoes, and these fit that role well. They have the look of a casual oxford, but the mesh upper makes them feel much lighter and easier to wear. That makes them useful for days when I want to look a little more put-together without sacrificing comfort. They are breathable, easy to walk around in, and work well with casual outfits. The only thing I’d keep in mind is that the mesh material can take a little extra care to keep clean, but that is a reasonable tradeoff for the comfort.

Summertime Comfort
Size: 6.5, Color: Light/Brown
My husband has a small foot and the shoe was a perfect fit for him, size 6 1/2. Normally this is a difficult size to find in a shoe. He was very pleased with the color and weight of the fabric. The fabric is breathable and lightweight. The shoes are very well constructed with a nice solid heel and sole. They are a perfect summertime shoe. The shoes will go well with shorts or casual trousers.
