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.

Almost perfect
Great for sublimation but it is thin. Only 0.2cm if it is 0.3cm it would be perfect. I will get 0.3cm next time. Not this one.

This is by far the best sublimation ink! I’ve tried other brands and this is the most vibrant and cheaper than most!
