Certainty® is a selective, post-emergent herbicide designed specifically for use in established warm-season turf. It targets some of the most difficult-to-control weeds — including nutsedge and unwanted cool-season grasses — without harming desirable warm-season turf when applied properly.

Ideal for homeowners and professionals managing Bermuda, Zoysia, St. Augustine, and other warm-season lawns.


Approved Turf Types

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

Do not apply to cool-season lawns such as Tall Fescue or Kentucky Bluegrass.


What Certainty Controls

  • Purple and Yellow Nutsedge
  • Kyllinga species
  • Globe and Annual Sedge
  • Annual Bluegrass (Poa annua)
  • Unwanted Tall Fescue
  • Perennial Ryegrass (transition removal)
  • Virginia Buttonweed (suppression)

Certainty is especially valuable for removing cool-season grasses from warm-season turf during spring transition.


When to Apply

  • Apply to actively growing weeds
  • Avoid mowing 2 days before or after treatment
  • Apply during warm, growing conditions for best uptake
  • Use a non-ionic surfactant for optimal performance

Application Rates (Per 1,000 sq ft)

Standard Rate: 0.028 oz per 1,000 sq ft

  • Repeat in 3–4 weeks if needed
  • Higher rate of 0.045 oz per 1,000 sq ft for dense infestations

Important: Always measure carefully. Certainty is highly concentrated and applied at very low use rates.


Why Choose Certainty?

  • Highly selective for warm-season turf
  • Excellent nutsedge control
  • Effective Poa annua management
  • Removes unwanted ryegrass and fescue during transition
  • Professional-level results with small application amounts

Certainty® is the go-to solution for precision weed control in warm-season lawns — especially when managing sedges and cool-season grass contamination.

Always read and follow the product label. Use only on labeled turf species.

Sensitive skin
Such a good product. I use after micro needling when skin is sensitive. Also a great product to use as a barrier serum when starting tretinoin cream.

Saved my skin during an eczema flare up
This saved my skin! I had an eczema flare on my face, and my usual products weren’t working. A friend recommended the Avene brand and within 3 days of using this rescue barrier serum, my flare was almost completely gone! This saved my face!

PLEASE REVIEW — FORMULA CHANGED!!!
I wish I would’ve posted a review PRIOR to the formula changing but just know that I LOVED this serum. I’ve struggled with hormonal acne (PCOS) and eczema for as long as I can remember. Finally, last summer my dermatologist put me on (3) different RX including Spironolactone and Accutane. I was so tired so I stopped everything except for CeraVe cleanser, retinol (Tretinoin) and CeraVe healing ointment. My made up skin routine was working until I used too much Tretinoin and burned my face. I had read great reviews about this product so I thought, I might as well try it — and IT WORKED! I’ve been using this product for almost a year and I loved it. However, 3 weeks ago when I ordered it, I noticed the bottle had a green tint. I could tell after one use that the feel of the serum was different, more watery, not as thick as it used to be. The smell was also different. Still, I kept using it for nearly 2 weeks and I experienced 2 breakouts! Sure enough, I stopped the product and within a few days, my skin was back to normal. I am very upset because as someone who has extremely sensitive skin, this worked but unfortunately, the new formula isn’t for me.
