  • Asked by Jeff from Paxton, Il
    07/29/2016
    Q
    Can Certainty be tank mixed with Tenacity?
    A

    According the the product label on Tenacity Herbicide, there has not been any testing on whether there are any issues with it being mixed with Certainty Herbicide or not. The manufacturer recommends doing a test on a small basis for compatibility. According to the Certanty Herbicide product label you would need to add water to the tank, then Certainty, then the Tenacity for the best mixture.

    10/17/2016
    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 I use Certainty to effectively treat yellow nutsedge in my flower bed?
    While at the same time ensuring it does not kill my ornamentals in the flower bed.
    A

    Certainty is only labeled to be used in woody ornamental plantings and perennial groundcovers.  It may harm flowers if they are sprayed or drift contacts them.  Care should be taken to avoid this and only use as a spot spray directly to the nutsedge in this area.

  • Asked by Jason from Atlanta, Ga
    03/10/2018
    Q
    Is anyone know the easy way to apply Certainty Herbicide using a hose end sprayer?
    I got 14,000 square feet to spray.
    A

    Certainty Herbicide like most other herbicides should not be applied in hose end applicatiors. This type of sprayer sometimes is not very accurate, so you can wind up dispensing more/less product than needed in a given area, which can lead to less than desirable results.

    3 - 5 small scoops or 1 - 2 large scoops per gallon of water per 1,000 sq. ft. 
    * Use a Surfactant to Increase Effectiveness 
    * See label for complete application instructions

  • Asked by Thomas from Midwest
    05/21/2018
    Q
    Question about Certainty herbicide. Can it be mixed with Pendulum 3.3 without compatibility issues?
    I've done this with Prodiamine before but not with an EC.
    A

    Certainty Herbicide - 1.25 oz. can be tank mixed with Pendulum 3.3 EC following each labeled instructions and rates.  Certainty would be added first than the liquid herbicide.  Before tank mixing, a simple jar test is recommended to insure compatibility of herbicides as directed on the label.

  • Asked by Theresa
    12/27/2010
    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).
