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.

Love Time
Color: Pink, Color: Pink
I love this watch 😍 I usually get the smaller gray/black one. Though this one is A LOT bigger than I expected. Not remembering the size of my wrist, plus the old saying is ... Why do women have a hard time telling distance ? Because we were told this 🤏was six inches long 🤣. The color wasn't quite how I thought it would be either, so that through me off a bit. I love the colors & I have been wearing Timex Iron Man watches for 37 yrs. I will not wear anything else. They'll last for years. Once the battery dies, I just get a new one. I also wear mine almost 24/7. I discovered these when I was 18 & needed a good watch for work (food service) whitch take a lot of beating. What's the old saying ? Time takes a licking and keeps on ticking. It's so true!!! I did try a couple before my Timex Iron Man, yeah, Nope. Timex is the best !!

Reliable watch, bad shipping
Color: Pink
I have had a couple other Timex watches. My 1st lasted many years before it quit working. This watch is my 3rd. My 2nd Timex still works but was smaller than I prefer so I bought this one. I'd have given this one 5 stars if it had arrived on time and not had made my subscription order arrive late as well because my items ship to arrive on a set day. My auto ship happened to be when I ordered this watch. I was given a tracking # for USPS at first, to arrive on October 27. Then got notification it would arrive the 28th, THEN got an email saying November 2nd and coming by UPS. It arrived 4 days after it was supposed to. The watch is good, but the shipping was not.

Nice looking, easy to read, comfortable silicone strap, hard to buckle.
Color: Black
This watch has all the features other Ironman watches have plus a 100 lap interval timer. The interval timer is possibly the reason this watch is slightly more expensive than the other IM variants with the same size and general appearance. I find this watch to be nicer looking when going out to dinner than the more common multi-colored IM watches, though most of the functions are available on the others. My previous Ironman watch had a resin strap, which was somewhate stiff when putting it on. It was comfortable enough wearing on the river, but later in the day I sometimes took it off for comfort. This watch has a soft, stretchy, more comfortable silicone strap, that, sadly, is hard to buckle and tuck-in.

Longtime Ironman Wearer -- I Hate This Watch
Color: Black
I've worn the old Ironman 100 Lap Watch for Years I would still be wearing those watches if the Indigo on them didn't consistently fail. My main requisite is large, easy to read digital display, and the ability to turn the Indiglo on 20 seconds a day once or twice to see time in dark. If I could have found a simple watch with a large display made by any other reputable manufacturer I would have bought it instead. I have truly come to dislike Timex because their Indiglo fails so consistently, on (5) different Ironman's I've owned. Doubt this one'll be any better, viewing it a disposable purchase after a year. Unsurprisingly, Timex is an American company, all marketing no quality, and yes I'm an American, looking at something Casio Seiko, Swiss or Japanese made. They get fundamentals right in terms of quality. The band on this is redesigned. Grippier. Tougher to adjust or put on, but more apt to stay on and not slide once on. I'm used to the old band, don't love or hate this new one. I will usually take my watch off while typing for a long time, not as easy to do with this, not a dealbreaker, can see the sense in making a swimming and exercise watchband a bit tougher. I hate the branding on this watch. Bright red Ironman logo on both ends of the band near the watch. Even worse is the Timex and Ironman words ATOP the glass on the watch. This means they throw shadows down onto the watch face below the glass. This effect gets even worse with the magnification underwater. Inexcusable design flaw, simply so some corporation can self-advertise its products. The combination of these two sets of branding make the watch look cheap, gaudy, and inappropriate for any remotely formal wearing. This would not have been the case if it was understated in color scheme. Without the two red marks on the band, and the absolutely moronic decision to place the branding on the watch glass, you have something understated you could get away wearing all the time. Not with the branding. There are also two lines running horizontally above and below the time. I hate these when I'm looking at it underwater. Haven't tried the lap functions yet, I usually open lake swim, maybe the lines help with that, but for my use I hate them. I'm 6'4" tall, people complain the watch is big, it feels to me if anything a bit undersized or the proper size, others may find it big. I would rather have a slightly larger size with bigger numbers. Biggest plus is time SUPER easy to read. I'd love to be able to turn date off and only have time display and nothing else in some mode. I don't need to check the date 6 times a day. Love to have mode where I press one button, upper left say, and date shows for five seconds or something. Indiglo about the same as old big Ironman 100, excellent--when it doesn't break which it almost always does. I have many of these watches where the time still shows but Indiglo never works, Timex themselves admitted to me this is a known problem. The rounder face, versus rectangular, better looks, but wonder if it is optimal way to make most readable. I would pass on this watch. I have always liked Ironman watches, but the branding is so bad, glass especially, and the absymal quality of Timex Indiglo, are unacceptable.
