    Q
    How much Certainty Herbicide do I need to get rid of broad leaf weeds?
    I have a normal turf lawn, and am interested in getting rid of the broad leaf weeds. I need to cover for a lawn of 3 acres.
    A
    Certainty should only be used on certain types of warm season grasses.  We can better answer your question if you can tell us what type of grass you mainly are trying to control the broad leaf weed in?

    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
    Will Certainty kill Chamberbitter without harming St. Augustine?
    I live in East Texas. These things look like miniature Mimosa trees, and they are very prolific. They are apparently quite hardy, Sedge Hammer won't kill them.
    A
    We recently started carrying herbicides due to customer request, but they are not yet our specialty.  We would like to refer you to the manufacturer since they are the experts on their Certainty product.  The manufacturer is Monsanto and you can reach them at (800) 332-3111. You can also contact your local cooperative extension office and request advice from the local master gardener who is well versed on the plant life in your region.

    Q
    When and what should I use to treat brown patch in St. Augustine grass in Texas?
    We had brown patch last fall and did not treat it. There are several huge patches in once acre of St. Augustine grass. We were told by the extension office to use Daconil and Immunox. I'm not seeing a suggestion or sale of these two products on your web site. What do you recommend for brown patch? We want to treat it now in the Houston, Texas area, so we do not have this in the spring-summer. Thanks
    A
    While we do carry many products to treat brown patch due to customer demand, our area of expertise is structural pests. We recommend that you either follow the advice of the extension office or call a landscape company that specializes in St. Augustine grass and ask them to come give you a free estimate (they usually will tell you what product they would use).

    Q
    Does Certainty kill Kentucky blue grass?
    Will it kill grassy weeds withot harming KBG?
    A
    Certainty is not labeled for use on Kentucky Bluegrass. We do carry several herbicides such as SpeedZone Lawn Weed Killer Concentrate and Tenacity Herbicide which are labeled for use on Kentucky bluegrass. We strongly recommend that you read over the product label of the product you choose (product label link will be under the picture of the product on each individual product page) to make sure you can use the product on Kentucky Bluegrass and to make sure the weeds you are trying to eliminate are listed. You can search Kentucky Bluegrass on our online store to see other products that may meet your needs.

  • Asked by Chad from Elizabethtown, Kentucky

    Q
    I am looking for the herbicide for dandelions, chickweed, and clover. I have tall fescue.
    A
    Certainty is not labeled for use on Fescue.  It actually will kill the fescue. 

    Our most popular general weed control product that is selective, meaning it will not harm your turf grass but it will kill your weeds, is End Run.  

    End Run is labeled for just about any weed you could have including clover, dandelions, and chickweed and will not harm your grass.  Best of all, it comes with a surfactant already mixed in the product so you do not have to purchase and mix a surfactant separately like you do with most of the other herbicides that we sell.

    Here is a link to the End Run:  http://www.domyownpestcontrol.com/endrun-herbicide-with-trimec-p-1501.html

    Please let me know if you have any further questions.

    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.

    My zeon zoysia lawn (sodded last summer) is being taken over by water grass
    A
    Certainty is a selective herbicide that kills many grassy weeds which water grass is a generic term for, in warm season grasses like zoysia.  It will kill the grassy weeds and not the zoysia grass.

  • Asked by Corey from Minnesota
    08/02/2012
    Q
    When is the best time to apply Certainty to kill Tall Fescue?
    I want to kill my Tall Fescue. I've read it is a "cool season grass." What is the best time of year to apply Certainty? In addition, is a surfactant necessary or does it simply aid the absorption? I have about 1/2 acre to treat Thanks
    A

    You should mix Certainty with a surfactant to increase its effectiveness. 

    It would be best to call your local county extension office for when to apply any type of herbicides or insecticides in your area.  They would know better than we would since we are not the manufacturer and we live in Georgia.  They will know exactly when you should apply it in your specific county.

    You can find your local county extension office information here:  http://npic.orst.edu/pest/countyext.htm

    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
    How many sq. ft. does a 1.25 oz. bottle of Certainty herbicide cover? .
    I am trying to get rid of kyllinga weeds in my centipede lawn and need to know how much coverage I will get with this 1.5 oz bottle of Certainty herbicide.
    A
    One bottle can treat from 10,000 square feet to over 35,000 square feet depending on the weed and grass you are treating. For the selective control of Kyllinga use 1.25 ounces per acre on Centipede lawns. The amount of water you use will vary as the water acts as the carrier. On average with herbicides you will use 2-3 gallons of water per 1000 sq/ft to give sufficient coverage.
