    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.

Questions & Answers

Have a question about this product?
  
Q
Controlling quackgrass in Kentucky Bluegrass

The Michigan State University extension website says "If your lawn is primarily Kentucky bluegrass, there is a selective herbicide that will remove the quackgrass without killing the rest of your lawn. This product is only available to professional lawn care operators, and they need to make two applications on a 14-day interval. The name of the product is Certainty." However, your Q&A section includes an answer that says Certainty is not "labeled for use on Kentucky Bluegrass." Can you clarify the apparent disconnect?

A
Since we do not make this product we have to go by what the manufacturer supplies us with. Kentucky Bluegrass is not on the label so we have to assume it cannot be used on that type of grass. However, here is Monsanto's telephone number 800-332-3111. We recommend contacting Monsanto and speaking with the customer service agent there to verify if this product is safe for kentucky Bluegrass.

Q
Quackgrass - Is Q4 effective at killing quackgrass?

Are there any chemicals available through your company that can eradicate quackgrass?

A
Quackgrass is a grassy weed, so you need a product labeled for grassy weeds.  Certainty is our most popular product for quackgrass and other grassy weeds.

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!

A
According to the product label, you should wait at least 3 weeks before re-seeding or over-seeding with Certainty.

Q
How do I kill tall fescue in a KBG lawn?

I thought I was going to be able to use Certainty to kill the tall fescue in my KBG lawn until I read the note on the label change after 2011. What is the right product to use now?

A
We do not carry a product that will take fescue out of kentucky blue grass.  Unfortunately they are so closely related that you cannot selectively remove it with any product that we are aware of.  Your best option in this scenario is to kill the fescue with a Ranger Pro (glyphosate) product and then re-seed with your KBG.

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.
