DIRECTIONS FOR USE

It is a violation of Federal Law to use this product in a manner inconsistent with its labeling. Read entire label before using this product. Use strictly in accordance with label precautionary statement and directions.

Do not apply this product in a way that will contact workers or other persons, either directly or through drift. Only protected handlers may be in the area during application. Keep people and pets out of the area during application. For any requirements specific to your State or Tribe, consult the agency responsible for pesticide regulation.

USE RESTRICTIONS

Do not apply this product by air or through any type of irrigation equipment. Do not use on golf course greens, tees and collars. Do not use on lawns with desirable clovers or legumes or on ornamentals. Not for use on sod farms in Arizona. For use in New York by spot treatment only (spray individual weeds only; adjust the sprayer to coarse spray to minimize wind drift, apply to the center of the weeds and spray to lightly cover). For use-specific restrictions in application rates and number of applications, please see APPLICATION INSTRUCTIONS AND RESTRICTIONS section.

USE TIMING

Apply Quincept to actively growing weeds as a postemergence broadcast or spot spray. Follow-up applications may be required for dense infestations of broadleaf and grassy weeds. Under certain conditions, application of Quincept made to annual grasses at 2 to 4-tiller may not provide complete control.

NEWLY SEEDED AREAS:

The application of Quincept to grass seedlings is not recommended until after the third mowing.

NEWLY SODDED, SPRIGGED, OR PLUGGED AREAS:

The application of Quincept to newly sodded, sprigged, or plugged grasses should be delayed until 3 to 4 weeks after the sodding, sprigging, or plugging operations. Delay applications for 4 weeks after seeding and emergence of Kentucky Bluegrass, Perennial Ryegrass and Fine Fescues.

SEEDING:

Delay applications for 4 weeks after seeding and emergence of turf species listed on this label.

MOWING:

It is recommended to not mow for two days before or two days after application. Clippings for the first three mowings should be left in the application area. Do not use clippings as mulch or compost around flowers, ornamentals, trees, or in vegetable gardens.

IRRIGATION AND RAINFALL:

If soil moisture is not sufficient prior to application, irrigation may improve weed control. For best results, DO NOT water or irrigate for 24 hours after application. If rainfall does not occur in 2 to 7 days after application, irrigation of at least one-half inch is required.

Do not apply this product by air or through any type of irrigation equipment.

MIXING INSTRUCTIONS:

Begin with a clean spray tank. Fill the spray tank with one-half the required amount of clean water. Slowly add Quincept while agitating, then complete filling the tank with water. maintain continuous agitation until spraying is complete. If left standing for extended periods of time, re-agitate to assure uniformity of the spray mixture.

Adding adjuvants may cause slight leaf burn, but turf vigor is not reduced. Delaying applications when relative humidity and temperatures are high may help to avoid potential for leaf burn and turfgrass damage. Low mowing heights may also increase the possibility of turf injury. The addition of chelated iron or sprayable solution nitrogen fertilizer will reduce slight yellowing.

For best results, the addition of methylated seed oil is recommended when it meets all of the following criteria.

  • be non-phytotoxic
  • contain only EPA-exempt ingredients
  • provide good mixing quality in the jar test.
  • be successful in local experience

Including additives when tank mixing with emulsifiable concentrate (EC) products may cause phytotoxicity. Adding oil, wetting agent, or other appropriate surfactant to the spray may be used to increase effectiveness on weeds but doing so may reduce selectivity to turf resulting in turf damage. Clean and rinse spray equipment using soap or detergent and water, and rinse thoroughly before reuse for other sprays.

This product can be mixed with some liquid fertilizers or liquid iron materials. Because liquid fertilizers and liquid iron differ in pH, free ammonia content, density, salt concentration and percentage of water, a compatibility test is recommended prior to mixing in the application equipment. All regulations, either State or Federal, relating to the application of liquid fertilizers or liquid iron and this product must be strictly followed.

Quincept may be tank mixed with EPA-registered preemergent herbicides (if compatible) for extended residual control. It is the pesticide user's responsibility to ensure that all products in the listed mixtures are registered for the intended use. Users must follow the most restrictive directions for use and precautionary statements of each product in the tank mixture.

The following compatibility test should always be performed prior to full-scale tank mixing.

  1. Pour 18 ounces of water into a quart jar.
  2. Add 1 ounce of either the liquid fertilizer or liquid iron to be used.
  3. Add 1 ounce of this product.
  4. Close jar and shake well.
  5. Watch the mixture for several seconds after shaking and check again after 30 minutes.
  6. If the mixture does not show signs of separating, the combination may be used. If the mixture foams excessively, gels, separates or gets very thick, do not combine for field application.
  7. Compatibility may be improved by the use of a compatibility agent. Follow the previously outlined test procedures and add 1/6 ounce of the compatibility agent between steps (the compatibility agent must be added to the fertilizer or iron before adding this product).
  8. If the mixture does not separate, gel, foam or get very thick, it may be used for field application. Mix only the amount to be sprayed. Do not allow to stand overnight.
  9. Sprayer Cleaning: Clean application equipment thoroughly before and after application to prevent cross contamination. Use a strong detergent or approved spray tank cleaner and rinse thoroughly.

It's not glamorous but it works wonders - even while I am on Accutane!
Size: 19 Ounce (Pack of 1)
This is the best, most luxurious lotion I have ever used. And the only lotion that I can even stand to be on my skin. I started Accutane (for acne) last year and was told that my skin would dry out horribly and that I needed to find a good moisturizer to limit the peeling and cracking that I would inevitably experience. Prior to the medicine my skin was oily and very acne prone and every lotion that I had tried either made me feel like I was wearing a latex suit or broke me out horribly. After doing some research I read that this was a great solution and figured I would give it a try. I started it out right away to try to avoid getting dry and was shocked at how well it worked. Even at the beginning when I was still oily this lotion never felt too heavy. Now don't get me wrong-it goes on like frosting and initially feels like a lot-but within minutes it soaks in and leaves your skin feeling like a little kids (not the sticky kind of little kid though-the good clean little kids with undamaged skin). It will last for days too. No need to reapply because it has soaked in to your skin and doesn't just sit on the surface. My skin has never been this soft. And here I am, nearly 9 months in to my Accutane medication regimen and I am not flaking or peeling. In fact, my skin has never looked better or more healthy. My doctors are shocked at how my skin has stayed moisturized because nearly everyone peels. And it doesn't break you out which is obviously something super important. Now, could I be an anomoly? Maybe, but I don't think so. I honestly think this lotion is Just. That. Good! The price isn't bad either!

Great for dry skin and the whole family
Size: 19 Ounce (Pack of 1)
We use this at home for everyone, including the kids, and it works really well. We all have pretty dry skin, and this cream keeps it hydrated for hours. I apply it after showering and it leaves the skin soft without feeling greasy. It has no strong scent, doesn’t irritate, and hasn’t caused any breakouts. I also feel comfortable using it on my kids because it’s gentle and effective. The jar lasts a long time since a little goes a long way. I would definitely buy it again.

Dry Skin Miracle!
Size: 8 Ounce
I have very dry skin, and around my chin and nose, it flakes and turns red, exposing my inner layer of skin due to severe dryness. I could never seem to hydrate it or get rid of the flakiness. I thought it was just my skin at this point, and I could do nothing to solve it. Now, I've never considered using Cerave; I've always heard negative things about it. However, I've never been a makeup person until now, when I want to try to elevate my look (not to mention I'm always in pain from a lack of hydration). The problem is, my skin is so dry that it cracks the makeup, preventing it from setting well on my face. Another problem is that around my nostrils, the flakiness looks like boogers, nasty. It's incredibly annoying. So I did a little research, and now I'm here. LET ME TELL YOU! This cream is amazing! I love how thick it is, and how a little goes a long way! My face, for the first time in my short life, is not dry! It's not buttery smooth, as in your hand won't glide against my face, but it won't feel the flakiness and roughness of my skin—and that's a game changer! I'm genuinely obsessed with randomly rubbing my face to feel the almost barrier of hydration, especially around my nostrils! I cannot explain the level of amazement I felt when I touched my nostril area to feel practically smooth skin. I felt as if it were a miracle. I've only used it for a week now, keep in mind, and this is how I feel. PLEASE BUY THIS IF YOU'RE LIKE ME! I'M SO HAPPY WITH THIS PURCHASE, AND IT'S WORTH ALL MY MONEY 🙏

Quietly effective leave-on exfoliant that smooths pores
Size: 1 Fl Oz
I bought this to tackle clogged pores and the occasional blackhead and to even out my skin without scrubbing harshly. I wanted a gentle option I could use daily without irritation, especially on the more sensitive areas around the nose and cheeks. In everyday use, I cleanse, pat dry, then apply a few drops and let it sink in. It dries down quickly, leaves no fragrance, and doesn’t feel sticky or harsh. It’s a liquid leave-on with 2% salicylic acid that helps unclog pores while smoothing dead skin, and I can follow with moisturizer and sunscreen without any trouble. What stood out the most is how it clears inside the pore and smooths texture over time. After several weeks I notice my skin looks more even and the fine lines around my eyes and mouth appear a touch softer. It feels hydrating while still doing the exfoliating job, which is nice to experience without extra dryness. A small note: there can be a brief, mild tingling if my skin is dry or I use too much at once, so I started with a smaller amount and every other day for a week. Sunscreen is still important during the day. Overall, it fits my routine well and I would rate it five stars.

Amazing exfoliating toner
Size: 4 Fl Oz
I am almost 40 and have had acne since puberty. I have tried so many products. The products that showed some improvement (like Proactiv) changed the texture of my face. Literally made my face feel like a basketball. I’ve tried some products that I’ll notice an improvement after a week or so, and the it would just stop working. I have never used something that so drastically helped my face in such a short amount of time. Notably, within 5 days my blemishes were almost gone. Within a week, my chin felt smooth instead of feeling the bumps of every clogged pore. The discoloration of my face, such as the redness, hasn’t totally disappeared, but it is improving. My face doesn’t feel oily throughout the day. My skin feels tighter, like I got a facelift. Moisturizer along with this product is important. And it is important to follow the directions and start slowly with this product. Use it every other day for the first week, gradually working your way up to daily and then twice a day. It is a shock to your skin and can dry it out if you go overboard. But for what I needed this product for, it has exceeded my expectations in every way. I couldn’t recommend it more. Just a heads up, it is applied like a toner. I expected a face wash, but it is a liquid that you apply to cotton and rub on your face. I wash with CeraVe SA cleanser, follow it with this, and apply whatever moisturizer you prefer—I’ve been using moisturizer with SPF so as to not damage my skin more than I already have.
