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.

returned- for now
Style: Updated Formula
I was using the lotion version of this for about a year, then went to the balm for more hydration. However, it seems to be breaking me out. I think because it's spring, im not needing as much occlusion as i did during winter. I'm gonna go back to the lotion formula, then pick this up again next winter. It is a little hard to spread, but I spray the avene mineral water on, let it dry slightly, and press the balm into my skin when its still wet. That helps thin the balm just enough to rub in. Otherwise, it can actually feel kind of rough!

Impressive
Style: Updated Formula
Nice thick cream! I even saw results (skin improvement) within days. I like this way better than their Cicalfate+, as it’s easier to rub in, less greasy, and doesn’t have the water vs cream separation issue. I’m not a huge fan of the pump top for this one, but at least it’s a tube instead of a solid canister (where you can’t see how much is left or get to the last bit).
