    Q
    When should Certainty Herbicide be applied to kill burweed?
    A

    Certainty Herbicide should be applied when the burweed is actively growing and healthy.  Usually weeds are best controlled when they have just emerged.  Please contact your local cooperative extension office to determine the more exact timing of the application as this will vary greatly from region to region.

    Q
    Can Fusilade II be used to effectively eliminate Quackgrass from a Kentucky Bluegrass lawn?
    A

    Fusilade Herbicide would not be recommended for KY Bluegrass. Quackgrass, unfortunately, is too closely related to Kentucky Bluegrass and most products that will kill quackgrass will also severely damage, if not kill, the KBG. The common recommendation is to kill the quackgrass with a glyphosate product like Roundup and then reseed with KBG. You might also check with a master gardener or local landscaping company in your area for their best recommendation.

  • Asked by Jim from Palm Coast, Fl

    Q
    How long does it take to see results after applying Certainty?
    A

    When treating with Certainty Herbicide it can take time to see results based on the weather. Per the product label:  Time to Symptoms: This product is absorbed by both the roots and the foliage of plants and rapidly inhibits the growth of susceptible weeds. Susceptible weed growth stops within 24 hours of treatment even though visual symptoms are slow to develop. Susceptible weeds usually show yellowing or browning within 2 to 3 weeks. Warm, moist conditions following application will accelerate herbicidal activity. Cold, dry conditions will delay herbicidal activity. Weeds stressed by drought are less susceptible to this product.

    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).

    Q
    How do I dilute Certainty Herbicide?
    If I am mixing this for 200 gallons and spraying at 2 gallons per minute, how much of this would I add? Also what is the best way of measuring this other than the scoop that comes with it?
    A

    The amount of Certainty needed will depend on the type of weed you are trying to control and the amount of water you use will vary as water only acts as the carrier and is not set on amount of product per gallon of water.  The rate range is 0.75 to 2.0 oz per acre mixed in 10 to 50 gallons of water per acre. The included scoop is generally the way to measure, but you can use another larger utensil (dedicated for this use or disposable) if desired.

    Q
    Can you mix Drive XLR8 and Certainty Herbicide together?
    I have segdes and crabgrass that we are trying to clean up in Celebration.
    A

    There are no restrictions on mixing Drive XLR8 and Certainty Herbicide together, as long as you follow both the Drive product label and the Certainty product label for the type of turf that you have. You should always follow the more restrictive label when mixing herbicides, and we would recommend performing a small tank mix to be sure the two products are compatible before mixing a large amount of solution. Another option would be Solitaire Herbicide, which controls both nutsedge and crabgrass. You should not add a surfactant to Solitaire Herbicide. For southern grasses, another option is Dismiss South Herbicide. Dismiss also should be used without a surfactant.

    Q
    Is Certainty Turf Herbicide a good selective post emergent herbicide for dallisgrass on Bermuda lawn? Also, what is a good pre-emergent?
    A

    For a post-emergent for dallisgrass, we would recommend using Certainty Turf Herbicide to supress the weed in bermudagrass. You will use 3-5 small scoops or 1-2 large scoops per gallon of water. This will treat approximately 1000 square feet.

    For a pre-emergent, we would recommend using Dimension 2EW Herbicide. You will use 0.28 - 0.73 oz. per 1,000 sq. ft. Please check the product label for times to use the product.

    Q
    Does Certainty Herbicide - 1.25 oz. absolutely kill Tall Fescue?
    Does certainty completely kill tall fescue, or only harm it? I'm looking to kill poa triv out of my fescue cool season lawn in a few spots. I'm thinking that if it only harms the tall fescue but kills that poa triv that would be great. Or, for a cool season lawn, is certainty essentially the same as glyphosate as it will kill all fescue, rye and blue grass?
    A

    For the poa trivialis there is not a good method to get rid of this weed other than to spot treat with a non selective product like Rounup QuikPRO and over seed in those areas, or you can use a pre-emergent like Prodiamine 65 WDG in the fall to prevent the poa from growing in the first place.  Certainty Herbicide is a selective herbicide with the active ingredient of Sulfosulfuron, which is not the same as a non selecetive Glyphosate product.

    Q
    Can Certainty Herbicide be used in or around vegetable gardens?
    I have an infestation of nut grass. Is there a better product to use against this infestation?
    A
    Certainty Herbicide cannot be used inside Veggie gardens. It can be used around the outside perimeter. Your best bet inside would be to spot treat with round up.

    Q
    Is it recommended to use a non-ionic surfactant with Certainty and Dismiss herbicides for St. Augustine grass?
    A

    Certainty is labeled to be applied to established St. Augustine turfgrass. Dismiss should NOT be applied to this type of grass as it is not labeled for any application on this species of turf. It is recommended to add a surfactant such as Non-Ionic Surfactant for Herbcides to Certainty.

  • Asked by Corey from Minnesota

    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
