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.

Actually stands up to use
Size: 4.5", Size: 4.5"
I have a pitbull who is a toy destroyer. All those toys, even the ones that say tough enough for destroyers, never hold up. THESE BALLS ARE AWESOME! I bought the 2 pack of the 4.5 inch balls and they lasted a year. I literally am writing this review after ordering a new set. These are well worth the money and Ghost (my dog) loves them. Hes a 103lbs pitbull and his life mission is cuddles and destroying his toys... and these lasting a year of everyday use is friggin awesome. Both toys failed in the same way eventually. They gave out in a circle around the "squeker".

Our German Sheppard loves these
Size: Medium
These cost a bit more than tennis balls, but they are so much nicer and longer lasting. For starters, they stay cleaner than tennis balls because they’re smooth rubber. Dirt won’t build up on them and if anything does stick, like grass or soil, it falls off once the dog slobber dries. They’re also thick, so they don’t fall apart or blow out like a normal tennis ball does in our dog’s jaws after 30 seconds. Our GS chomps on these like crazy and the only damage they’ve suffered is a crack that developed from the edge of the hole, but the crack is growing very slowly and none of these balls have totally failed yet. The balls do whistle when thrown ant high speed and that may help a dog track and locate it, but I’m not sure. Our neighbors hear the whistling too so it’s far from silent. Lastly the orange ball is easy to locate out in our yard, but the dark blue practically disappears.

Great for smaller dogs
Size: Small
These two balls are perfect for the smaller mouthed dog that loves to play fetch. These balls are not only super durable (lots of teeth biting), but float in the baby pool we use for our miniature dachshunds. The value here is much better than you’d find anywhere else. The noise, if bitten hard enough, was “low” at best. Easy to spot/find if overthrown. Will definitely buy again once these are in bad repair; so far, so good-love these for my fur babies!

My dogs favorite balls
Size: Medium
These are great for my dog who always has to have a ball in her mouth. Not too hard so I don't have to worry about her teeth. They last for ever. They do lose their shape a little over time (like I said, she always has a ball in her mouth) they become a little oval in shape. They still bounce, she still chases it and she still chews on it so I don't think she notices or cares. I've gotten her a bag full of these over time and I have only seen one that she chewed a chunk out.
