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.

Works and is engineered exactly as I expected it to be. Unlike SO MANY OTHERS.
Color: 2-Speed Rechargeable Set with Charging Base
I've ordered about 4 different automatic shakers from different brands. They all have different problems, motor not strong enough, charging cable on the front of the charging base (in the way on a counter), hard to open refil covers, small containers not holding enough salt/pepper. FINALLY this one checks all the marks I've been looking for. Its weighty too since its made of stainless. Large refil container, easy to remove just a twist. Grind selector is a twist at th e base with a clear arrow showing size. Large press button at top so you can hold it in any rotation in your hand and not have to look for the button/switch to turn it on. No cover that needs to be flipped open and then closed to put back into the base. Contacts for charge are on the back side and not at the bottom where salt can corrode the contacts. The list can go on but you get the idea. Just buy this one and be done with it!

Nice product
Color: 2-Speed Rechargeable Set with Charging Base
Edit: Customer service actually did offer to replace it. Received the new set and it works fine. Nice set. Only gripe is I think that the motor could be a little stronger. Sounds like it’s struggling at times. Received a defective item reached out to customer support for Circle joy and they’re basically saying that it’s user error and not a defect in their product, even though I explained to them that the other one works fine. When adjusting the coarseness on one of the grinders, the grinder ends up loosening up, which ends up with you spilling the pepper corns everywhere. It’s a nice set if it worked right but for $40 I expect her device to be a little more polished.

great for my bad hands, hygenic, easy to use.
Color: 2-Speed Rechargeable Set with Charging Base
so far so good. I cook a couple times a day. I also have bad RA in my joints. this product has really helped already. from the clean size adjustment to the ease of charging. Like i have owned it for years is how easy this product has entered my kitchen routine. strong product and hygenic because you adjust the grind from twisting the body, not messing inside the grinder.
