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.

Wonderful
Format: Kindle
The amount of detail in this book is so interesting and the specifics of so much theoretical ideas revolving around true ideas makes it so fun to read. The writer does a great job and describing every situation enough where you get the point but not too much to try to bore you . The book is very easy to follow, keeps you on your toes, was pretty funny to me, and truthfully just a great book for anyone!

Read it in 2 days
Format: Paperback
This is science based science fiction. How refreshing to read science without turning the story into horror. Without a plethora of characters, it is easy to remember who is who. The story moves along well enough that I wanted to keep going. It us a p age turner in many respects. All this said, there were too many crises suddenly resolved like some Star Trek episode from 1966. It reached the point where I said to myself, "OK, this doesn't matter. Move along, nothing to see here." There was good humor, some surprising twists, and enough involvement with characters that I didn't want to put it down. As science fiction goes, it was good like pulp stories go. It wasn't like Ursula LeGuin or Robert Heinlein but I would probably pick up the next book he writes.

Excellent story
Format: Kindle
This book is worth your time. It is a great introduction to a variety of scientific disciplines without insulting the reader. It also respects and understands humanity, engineering, history and political science. Then it lays that foundation to tell the story of a unique friendship of two beings with mutual goals who have to communicate and problem solve together. Along the way, you can really contrast how Grace and Rocky do it, vice the Hail Mary team did it.

A book worth rereading
Format: Hardcover
This was a book club pick. Honestly, I wouldn't have chosen to read this myself, but I'm glad that I did. I would have missed out on an incredible story. I've been reading a lot of thriller and fantasy books lately, that I forgot how much I enjoy sci-fi. This brought it back for me. There's a lot of science-heavy discussions in the book and I loved it! When I got to a subject or term I didn't know, I would go online and learn more about it. I feel that Grace is a dork like me because he wouldn't curse. He had little anecdotes he uses in place of swearing. Something I definitely do myself! A lot of the book is the MMC talking to himself. Surprisingly, it worked. There's so much humor that it kept the story going. There was not a lull. Usually I dislike info-dumping as an introduction to get all the background story told, but I didn't mind it at all. Maybe I'm being biased because I love science talk. **SPOILERS AHEAD** What makes the whole plot engaging is the fact that the plot doesn't seem too fantastical. It's something that could happen. There's a lot of ethics and morals involved in determining what should be done. I would hate to be in a position where I have to chose what's best for everyone. That's why Stratt is a necessary character. I hated some of her decisions and how she operated, but you need someone who's focused on the general welfare of humanity. I would be too focused on myself, my family, etc. As much as it hurts to admit, I'm selfish (and a coward) like Grace. I wouldn't want to die. But was it right for Stratt to force him on the mission? This could also be taken religiously. If God has a plan and things happen for a reason, is it our right to deter what's going to happen? God wiped out the world many times because of humanity's sins, what if this was God's doing? So many questions and debates on right vs wrong, ethics vs morals, and religion vs humanity made for a incredible book club discussion. I love how this book ended. I wish I could continue reading about Rocky and Grace's adventures, it's that fascinating. However, I think Grace staying on Erid was the best outcome. If the roles were reversed, I don't think Rocky would have the same welcome. I feel that those in charge would have dissected and kept Rocky hostage, all in the name of science. Just as the Astrophage were first introduced, the first things the scientists did was poke and probe. Essentially torturing the Astrophage to see what makes them tick. I think Rocky would have the same fate. Oh, and my favorite part is the relationship between Rocky and Grace. I cried so many times when I was reading. Scared that something bad was going to happen to either of them. Especially in the scene where Rocky busted out of his tunnel to save Grace. I got upset and told the book that 'if Rocky dies, I swear, this is the worst book ever!' And the scene where Rocky learns about radiation poisoning. How he slowly becomes aware of what happened to his crew, his friends. I was a mess. This book is definitely one that I could go back and reread. I did watch the movie afterwards. There's a lot of differences to adapt the story to screen, but it was okay. They got the humor down pat, but I didn't get the direness of the whole situation nor the special bond that both MCs had.

A Brilliant, Emotional, and Unforgettable Sci-Fi Adventure
Format: Paperback
Project Hail Mary by Andy Weir is one of those rare novels that delivers everything you could want from science fiction: gripping suspense, fascinating science, humor, heart, and a genuinely moving story about survival and friendship. The novel follows Ryland Grace, a middle school science teacher who wakes up alone on a spacecraft with no memory of who he is or why he’s there. As his memories slowly return, the stakes become clear: humanity is facing extinction, and he may be the only person who can stop it. The mystery unfolds at a perfect pace, blending high tension with moments of discovery that keep you turning the pages. What makes this book stand out is how seamlessly it combines hard science with accessibility. Like the author’s earlier work, the scientific details feel authentic and well researched, but they never overwhelm the story. Instead, the problem-solving becomes the engine of the plot. Each obstacle feels real, and the solutions are both clever and satisfying. The biggest surprise—and the emotional core of the novel—is the relationship that develops during the mission. Without giving anything away, it adds warmth, humor, and depth that elevate the story far beyond a typical survival thriller. By the end, the novel becomes less about science and more about courage, trust, and the willingness to sacrifice for others. The pacing is excellent throughout, with a balance of suspense, humor, and heartfelt moments. If there’s a small drawback, it’s that some plot developments feel a bit convenient. But the strong characters and emotional payoff more than make up for it. Overall, this is a must-read for fans of science fiction, space exploration, and anyone who enjoys smart, character-driven storytelling. It’s thrilling, funny, deeply human, and surprisingly emotional. I finished it feeling both entertained and uplifted. Highly recommended.
