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.

Very pretty cookware
Size: 11-Piece Set
This is nice quality cookware for a great price. I have seen cooking shows that tell how to cook in stainless steel without it sticking. Unfortunately, my food still sticks. If I use a lot of oil, it isn’t so bad. One cooking show host says if you get it real hot before you add the oil, it won’t stick. It sticks. I am trying to get away from using Teflon because they say we have a lot of Teflon in our bodies from our cookware. I still go back to my Teflon a lot. But the cookware is very pretty, a nice weight, and cleans up fairly easily. I do soak the skillet before I clean it. I don’t have to do a lot of scrubbing. The sauce pans are great.

Cooks well, cleans easily
Size: 15-Piece Set
Bought this to replace old nonstick cookware. Looks good and not too heavy. Pot handles are cool enough to hold near the ends but tend to warm up close to the pot itself. Using on a gas range – heat spreads quickly and cooks. Best on low heat. Some sticking problems with food like cereal, lower heat advised. Glass lids are very handy with steam outlet. Have not used all of them yet, but they store and stack easily and I was looking for a good size stock pot and this should suffice. Not as heavy as other stainless steel cookware. Price reasonable for the number of pieces included.So far I am very pleased with this purchase.

Heat up well before use for "non-stick".
Size: 11-Piece Set
I really l Iike these stainless steel pots. I had to learn the trick to using them, and that is to make sure they are heated up properly before using. This makes them "non-stick" and your food won't stick to the bottom of the pot, especially if you're frying it. Also follow the manufacturers instructions and "season" the pots after you receive them, by coating the insides with oil and heat them up. They cook really well, are light weight, easy to use, easy to clean, very sturdy, shiny surface, and holds heat after you've finished cooking. Also, don't use harsh scrubbers in them because it will scratch the surface. Scotch Brite Scour Pads work well in these pots. If you scratch them, use the green Scotch Brite Scour Pads to polish the scratch marks out. Enjoy them!

EXCELLENT DEAL.
Size: 5-Piece Set
These are authentic food grade, stainless steel pots and pans sold for ten times more via other companies. I did the research and the part where we cook or boil is stainless steel. The core is aluminum (we don't get that when we eat) and the outside is stainless steel again. Beware, though, they are SUPER HEAVY. Lift weights before picking them up! We love them. Wish we'd bought them sooner. You can't cook on high with them, though, b/c it will burn the food, since it isn't nonstick. We've learned to cook low and slow. No need to scrub so much. That's the only drawback. Great quality!

Yeah 😎 get em why not? lol
Size: 5-Piece Set, Size: 5-Piece Set
Paid $85. These feel nice, look nice, these are heavy but shiny, quick warmup. These are heavy. The lids won't lift while cooking or make sounds for air or bubbles which is good. It worries me that the one pot I use everyday the big one, the glass lid starts making cracking sounds as if about to break... Weird... Every time I cook it feels as if I'm waiting for something bad to happen and ruin my dinner. Overall, giving 3 stars, due to the glass cracking thrill, and the bottom of the pots give weird stain spots after cleaning. I used aluminum foil and little water to remove those stains. Well... Dark dirt came out but now these are back to shining. So it is burnt something perhaps the olive oil I cook with? But yeah one must foil clean these pots at least once a week as it takes effort to clean those bottoms... Is there a product that resolves this issue? I guess I'm too young for this 😂 I would recommend if you like fancy at a good price. Ahh and that the flat one is the worst for egg frying, I tried 2 times once w olive oil and then with coconut oil both times fried eggs were really sad 😢 waste of eggs. Anyhow. ... Do the math and if you like 'em just get 'em.
