Certainty® Herbicide is a selective, post-emergent herbicide designed to effectively target and control a wide range of stubborn weeds in warm-season turf. It provides professional-grade results while keeping desirable grasses healthy and thriving.

Lawn Types Suitable for Certainty Herbicide

Certainty is ideal for use on the following warm-season turfgrasses:

  • Bermudagrass
  • Bahiagrass
  • Buffalograss
  • Centipedegrass
  • Kikuyugrass
  • Seashore paspalum
  • St. Augustinegrass
  • Zoysiagrass

This makes it a great choice for residential lawns, commercial landscapes, sod farms, and golf course applications.

Why Use Certainty Herbicide?

Certainty is specifically formulated to control hard-to-kill weeds without harming established turfgrass. It effectively manages:

  • Purple and yellow nutsedge
  • Kyllinga species
  • Globe and annual sedge
  • Tall fescue
  • Perennial ryegrass
  • Annual bluegrass (Poa annua)
  • Virginia buttonweed (suppression)

Its precision targeting allows for the removal of invasive weeds while maintaining the health of your lawn.

Best Time to Apply

For optimal results, apply Certainty when weeds are actively growing. Avoid mowing for at least two days before and after application to allow maximum absorption and effectiveness.

Mixing Rates and Application Guidelines

Proper mixing and application ensure the best results. Here are the recommended rates:

  • Sedge Control: Apply .028 ounces/1,000 sqft when weeds have reached the 3- to 8-leaf stage. If necessary, a second application of .028 ounces/1,000 sqft can be made four or more weeks after the first treatment.
  • Tall Fescue Control: Apply .028 ounces/1,000 sqft, followed by a second application of .028 ounces/1,000 sqft 21 to 28 days later. A single application of .045 ounces/1,000 sqft can also be used.
  • Dallisgrass Suppression (in Bermudagrass): Apply .028 ounces/1,000 sqft of Certainty combined with 2 lbs. of MSMA per acre and 0.25% nonionic surfactant (1 quart per 100 gallons of spray solution). A repeat application 2 to 4 weeks later improves results.
  • Annual Bluegrass (Poa annua) Control: Apply .028-.045 ounces/1,000 sqft, using the higher rate for dense infestations.
  • Overseeded Perennial Ryegrass Transition: Apply .028 ounces/1,000 sqft, followed by a second application 21 to 28 days later. For a single application, use 045 ounces/1,000 sqft.

For best results, always mix Certainty thoroughly with water and use a nonionic surfactant to improve herbicide absorption.

Certainty® Herbicide is the go-to solution for managing difficult-to-control weeds in warm-season turf. Its selective formulation ensures superior weed management without damaging desirable grasses. Whether you're tackling nutsedge, Poa annua, or invasive fescue, Certainty delivers professional-quality results, helping your lawn look its best year-round.

That ending 😫
Format: Kindle
I fell into a false sense of security and really thought this was gearing towards a happy ending. Then I realized there’s no work they don’t punish Andrew. I really liked Vale’s character. I don’t normally read books with pregnancy but going into this knowing she was pregnant made it more enjoyable for me. I loved Bishops devotion to her and her happiness. I also loved that Holt and Mercy couldn’t fight their attraction to her. I love scent matches so very much. I’m so curious to see how this duet will end up. And I need to pay more attention and notice that a book I’m starting is a duet to begin with lol

oh wow
Format: Kindle
I just knew there was something about Cooper! I’m wondering if he’s about to be included but damn I’m glad he’s at least not a rapist and creepy guy, he just got called on assignment and had to go! This should be interesting! She’s gonna run and then what’s his face is gonna grab her. I’m worried! Wow that was a great book and cliffhanger! Loving this!

A good read
Format: Kindle
A good read, just fluffy cuteness, no antagonism. I like all the characters. It could have used another round of editing however, glanfds being one error that cracked me up, and my personal pet peeve was that the author kept using the word fill instead of feel, which I promise you are not interchangeable haha, but it's definitely better than the majority of books I read on here mistake-wise.

amazing
Format: Kindle
Knot the Bride was a fantastic read! The characters were all amazing and well-developed. It was easy to like them all. Sophia, Luca, Nick, and Gavin were all perfect for each other. It was such a charming story that had me hooked the entire time. I did wish there were POVs from Luca, Nick, and Gavin but it was still an amazing book without it. I am excited to read the next book in the Willowside Omegaverse series! This is definitely a must-read for fans of omegaverse romance!. I received a free copy of this book and am voluntarily leaving a review.

3 Star Read,
Format: Kindle
This book wasn't bad, but wasn't my cup of tea. It's highly disappointing because the storyline is so original. There is no real conflict or resolution, so the entire thing feels flat. As a lover of omegaverse books, I know there is a ton of variety out there, and ov is really up to the author. But this one is weird. Omegas have multiple scent glands all over their bodies and go into week long heats every month. Alphas have knots in the middle of their shaft instead of the base, and the knot doesn't always swell, no explanation of when or why. It doesn't engage at all when the mouth is in play. I also didn't enjoy the author's writing style. Each paragraph is only 1 or 2 sentences long, and the entire book reads very stacato. The conversations are stiff and unnatural feeling. Everything is very repetitive, both in word choice and in thought. The same thing is repeated 3 or 4 times over a single page, multiple times over. I ended up doing so much skimming. The first 50% of the book is all slow burn, and the last 50% is almost straight mediocre spice. This wouldn't have been all bad if the grammar and spelling errors didn't start at the exact same time. Tongue is repeatedly misspelled in the middle of the spice.
