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

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.

Still looking for a better brand
Flavor Name: Original Beef
These are fine for what they are and are better than most brands. I loved their discontinued Cranberry Habanero beef sticks. Those worked great within my KETO lifestyle and were their best tasting offering. Then, these fools decided they wanted to basically cater to Carnivore or Carnivore-leaning lifestyles and did away with the best version of their meat sticks. They've never gotten the basic Habanero beef sticks to where I like the taste. This plain version will do as will the Salted Beef sticks until I find another brand that does a decent Cranberry Habanero or similar offering without the ick. However, the last box of Salted Beef sticks that I purchased directly from Chomps both tastes and feels underdone to me and I have to heat before eating them. I also ordered and tried their limited edition Smoky BBQ beef sticks. They were just meh. Had my brother try them and he also said they were meh. Decent brand but I am still looking for a brand to come into the arena and lay waste to all of the others. UPDATE: I purchased two boxes directly from Chomps. They are trash. Got sick after eating two. Some smell absolutely horrible upon opening and others in the boxes taste disgusting. The ones that haven't smelled or tasted bad at first bite, DONT TASTE DONE. That's it. I won't be purchasing from Chomps either through Amazon or directly. I no longer like or recommend this brand.

Great tasting
Flavor Name: Wagyu Beef Steak, Size: 20 Count (Pack of 1)
I ordered both the wagyu beef and the venison . Just received them today. I’ve only tried the wagyu beef so far and I’m very impressed. It’s not overly salty and more like a dried hamburger beef. Not to dry to need a flosser like other Jerky’s. The venison is way to salty I definitely prefer the Wagyu

The best meat sticks!
Flavor Name: Wagyu Beef Steak, Size: 20 Count (Pack of 1)
These are the best meat sticks I’ve found so far! They are very clean and go down well. Very tasty. If you need more protein on the go-these are a no-brainer. Slightly pricey, but worth it!

Not bad. Read the box.
Flavor Name: Wagyu Beef Steak, Size: 0.8 Ounce (Pack of 10)
First of all, this isn't really beef jerky and nowhere do they state that it is. Simply put, it is not your typical beef jerky. I don't know how these are processed because there are not nitrates, nitrites, or even celery powder - which are the ingredients used for curing meat. Yes, these are ground and formed meat strips, just as it says on the box and on each individual strip wrapper. These lack all the extra preservatives and additives that other strips and jerkys have. And although some of the other meats that they have are flavored with cranberry, apple, or bacon, these don't have much flavoring at all. Just added honey, which keeps it from being totally vile. When I first opened the package, the scent was that of old time (not ancient) jerky. The way jerky looked and tasted in the 70s. But the flavor is really meaty/bloody tasting, with little hint of honey that makes it palatable. I'm not hating on this, it's rather not really too bad... just gotta get used to that bloody raw meaty taste. I've had their beef/bacon/cranberry bars and those were not edible. They were totally disgusting. Maybe it's because these are thinner and more like jerky (you get less of a mouthful) that I find them easier to swallow. I'v had quite a bit of their "bacon" bars (note, they are bars, not strips), and really wish they'd make the bacon bars thin like these strips as well. Although I like the bacon best, sometimes it's just too much... it's like spam but not as tasty. The texture of these is much better. Bottom line, if you expect these to taste like O'berto stips, then don't get them. If you expect something that tastes like a caveman's dinner, then this is it.

Meh
Flavor Name: Wagyu Beef Steak, Size: 20 Count (Pack of 1)
This is not beef jerky but rather and "ground and formed" meat snack. Not particularly rich, not particularly flavorful, and thus not particularly Wagyu.
