    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.

  • Asked by Bart from Frisco, Tx
    06/15/2016
    Q
    When are the best times of the year to apply Certainty to kill Poa Annua?
    A

    The best time to apply Certainty for poa annua or for any of the other listed weeds on the label would be when they are actively growing. 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 will know exactly when you should apply it in your specific county.

    You can find your local county extension office information here:  http://www.csrees.usda.gov/Extension/index.html

  • Asked by Chad from Elizabethtown, Kentucky
    04/03/2012
    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
    Will Certainty Herbicide - 1.25 oz. bottle kill Dallisgrass?
    Is there a good post emergent selective herbicide for dallisgrass in bermuda? Also, what is the best preemergent to prevent dallisgrass?
    A

    Certainty Herbicide - 1.25 oz. bottle will suppress Dallis grass. Per the product label:

    For suppression of Dallis grass in Bermuda apply this product at a rate of 1.25 oz per acre in a tank mix with 2lbs MSMA per acre and .25 oz Non Ionic Surfactant. Re apply same tank mix 2-4 weeks after initial application. 

    Barricade 65WG would be an excellent pre-emergent product choice to treat dallisgrass(Paspalum).

  • Asked by Shaun from Braselton, Ga
    02/24/2019
    Q
    How long before noticing any symptoms on weeds especially poa annua when using Certainty?
    A

    You may notice signs of the poa dying (discoloration-yellowing or browning) within 2-3 weeks after you have applied Certainty but it is normal not to see anything for at least a month. Per the product label, you can make an additional application 4 or more weeks after the initial application as needed. Best results are obtained when target weeds are actively growing & not disturbed by mowing for at least 2 days before and 2 days after application. Warm, moist conditions following application will accelerate activity; cold, dry conditions will delay activity. Drought stressed weeds are less susceptible.

    Q
    Will Certainty Work For Me?
    I have a 0.40 acre lot that is infested with quackgrass. I am not sure what the grass type is, but I live in Minnesota. Will Certainty eradicate the quackgrass and is 1.25 oz enough?
    A
    Certainty is labeled to control quackgrass and is safe to apply on warm season grasses.  If you are unsure of your grass type we would recommend contacting a local lawn care company to help determine the type.  Without knowing for sure what your lawn is we cannot say that Certainty would be the product to use.
