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.

It's great for food delivery and driver jobs
Size: 7''x3''
My husband got this for food deliveries and uber/Lyft. The app let him add several texts. I believe he added 4. He was able to design it how he wanted it. It seemed fairly easy and I liked how it looked. The words would scroll over, like... Uber eats, etc... It included a big roll of strong red tape. The led screen product is charged by wall plug, phone, or the car usb phone charger. I think it was a spectacular product. I thought it was limited to 4 letters since it is small in size.

Very good LED sign for cars, studios, desks, etc
Size: 1PCS 15''x4''
Great! Item really stands out. This LED sign by Ray home features way more than just devil eyes. There's a lot of pre-built templates for every gig work there is out there for your car. Item was described. A bit dim during the day but at night really shines stands out. You can customize it with uploads withdrawing. You can have programs that animate between the different signage. It's a great product for a car or for your home. To be honest, I can see a lot of uses for this. High quality design. Easy to work app. The adhesive is great for glass. It's reusable plus it comes with strips. If you want to mount it permanently not on glass. Overall a great deal.
