Product Overview

Certainty Turf Herbicide is a selective, post-emergent herbicide that controls labeled weeds in residential and commercial turf and ornamentals.

Certainty Turf Herbicide is easy and flexible to use.  Certainty weed killer offers excellent control of both purple and yellow nutsedge, Kyllina, globe and annual sedge, and broadleaf weeds.

With Certainty Turf Herbicide, you get the most complete package of turf safety, application flexibility and broad-spectrum weed control versus the competition.

    Kills poa annua in centipede

    By Rich on 02/22/2015

    Verified Purchase

    After fighting poa annua for the last few years it is good to find something that works. It seems expensive for such a small amount of product, but the amount used per gallon of water is so small it is cost effective. Works much better than the atrazine I used before. Great product and produced results in only 2 weeks.

    Quackgrass Dead On Arrival!

    By Ken on 05/26/2016

    Used properly per instruction, quack grass started turning yellow on 3rd day, bright yellow by the 7 day, and wilting over 2 weeks out. Must use the Dyne Amic with this product. See my other review for (Drive) product. Newly planted Princess 77 lawn. Killed all the Quackgrass, the Bermuda kept smiling!

    Awesome

    By Jeff on 07/07/2015

    I had a bad infestation on nutsedge and we were getting a lot of rain everyday decided to mix it up and give it a shot in front of the rain one day only three hours before receiving half an inch of rain but within 7 days the sedge is already 90% dead. Well worth the money

    Green Kyllinga in Florida St Augustine grass

    By Homeowner on 04/30/2014

    I applied Certainty to my St Augustine lawn in April. The St Augustine did not show any signs of stress. Kyllinga did not shrivel up and die the next day, but it did stop coming up in my lawn. I'm very satisfied. The rest of the 1.25 oz bottle should last me for years to come so it is cost effective in the long run.

Q
I am applying Certainty Herbicides and the instructions indicate I need Non-ionic surfactant. What would be an example of that?

I will be applying this to my bluegrass lawn.

A
We offer DyneAmic Surfactant on our website. DyneAmic is a high quality non-ionic surfactant that greatly enhances the effectiveness of Certainty and other herbicides and fungicides on lawns, ornamentals, trees and landscape areas. The surfactant helps penetrate the natural waxy tissue of plants.

Q
How soon can I re-seed after application of Certainty?

Live in MA. Have a predominantly KBG lawn, with some tall fescue creeping in places that I would like to get rid of. After application, how soon can I re-seed any bare spots or over-seed the whole lawn? Thanks!
