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.

Perfect
Color: White, Size: 12x12 Inch
These are great quality pillow inserts. They arrived very securely vacuum packed. Be careful when opening. I followed the directions and they were fluffy within a few minutes. They are small, but this is the size that I needed. I am glad that I didn’t order a few inches larger, as recommended by many. They fit perfectly in my 12x12 inch pillow covers. I would recommend this brand and seller for purchasing this product.

Fluffy and Supportive Pillow Inserts
Color: White, Size: 12x20 Inch, Color: White, Size: 12x20 Inch
I used these pillow inserts for my couch cushions, and they’ve worked out really well. They give my throw pillows a nice full look without being too stiff or flat, which makes the couch feel more put together and comfortable. Filling quantity: They’re nicely filled and give good shape without feeling overstuffed. Durability: They seem well-made and hold their shape well even after daily use. Color: Clean, bright white that works well with different pillow covers. Appearance: They make my decorative pillows look fluffy and full, giving the couch a more finished look overall.

Very Straightforward and Easy to Use
Reload type: One Time Reload
I have used this several times, and it has always been a smooth and convenient experience. The biggest advantage is how intuitive the process is. Reloading the balance is simple, quick, and easy to understand without unnecessary steps or confusion. It is especially useful for managing spending, setting a shopping budget, or keeping funds ready for future purchases. Instead of entering payment details every time, having balance available makes checkout faster and more convenient. I also appreciate how quickly the funds are applied, allowing immediate use once the reload is completed. This is one of those simple Amazon features that works exactly the way it should. Overall, easy, efficient, and user-friendly. I have been very satisfied with it. Five stars.

Monthly reload for Subscribe & Save Orders
Reload type: One Time Reload
Not a glamorous review, but a genuinely useful tip for Subscribe & Save users. I reload about $100 to my gift card balance once a month, a week or two before my S&S order processes. Amazon pulls each Subscribe & Save item as a separate transaction, which means 10+ individual charges hitting your bank account on before or on ship day. A headache for budgeting and a minor anxiety trigger if you're watching your account for unauthorized activity. Loading the balance first consolidates everything into one clean transaction. Your S&S order then pulls from the gift card balance rather than your card directly, and your bank statement stays tidy. The side benefit is built-in budget discipline. I set about $100 as my monthly Amazon ceiling - if my cart runs over, something gets pushed to next month. It's a simple system that keeps spending intentional without any extra effort. If you're a regular S&S user who wants cleaner finances and less ""wait, who charged this and what was that charge?"" moments, this is worth making a habit.
