  • Asked by Robert from Orlando, Fl
    05/14/2018
    Q
    Is Tenacity Herbicide a good choice crab grass control in Centipede grass?
    I live near Orlando, FL and have centipede grass. What is a good product that I can use for general weed control? I have several areas with weeds, but not all over the entire yard. I'd like something I can put in a pump sprayer. I know one of the weeds I have is crabgrass, but not sure what the other ones are.
    A

     

    Tenacity Herbicide? would be a great option for you to control crabgrass, along with many other common weeds, without harming your Centipede lawn.  Tenacity needs to be tank mixed with a non ionic surfactant? or the best results and stick to the leaf surface of the weeds, and its advised to use a dye like Turf Mark Blue? with it so you can make sure to not overlap if you plan to do a broadcast application on the property. According to the Tenacity product label you will need to mix 1/2 tsp of product + 1 1/2 tsp surfactant with 1 gallon of water for spot treatments. After spraying with Tenacity Herbicide, the foliage of treated weeds cease growth after application, then turn white (loss of chlorophyll), and death may take up to three weeks. A repeat application is required after two to three weeks for improved postemergence weed control.

  • Asked by Keith from Delavan Wi
    05/19/2014
    Q
    Will Tenacity kill creeping charlie?
    A
    Tenacity is labeled to control Ground Ivy "Creeping Charlie" as post emergent control. We highly recommend using a temporary turf colorant like Turf Mark Blue so that you can see where you spray with the Tenacity to avoid overlapping. Tenacity is a great product, but also a very strong product so too much overlapping or mixing the product too strong can cause temporary damage and whitening to your turf around the ground ivy. The color will come back in the lawn after 3-4 weeks but to avoid this potential problem it is best to use a colorant to make sure no overlap occurs. To get optimum results for post emergent control it is recommended you use a Non Ionic Surfactant in your mixture as well. Please make sure that you check the label to verify that it is safe for your type of turfgrass as you did not indicate the kind of lawn you will be applying the product to. Please let us know if you have any questions.

  • Asked by David from Hermitage Tn
    08/05/2019
    Q
    Is Tenacity safe to use around ornamental plants and shrubs such as coneflower, hostas, rhododendron?
    Crabgrass has infested our ornamental beds which also have sky pencil hollies, black eyed susans, clethra and spirea. Can I safely spray the crabgrass without killing the ornamentals? Thanks.
    A

    Tenacity Herbicide should not be used within 3 feet of desirable trees or ornamentals.   If treating actively growing grassy weeds, Fertilome Over The Top II Grass Killer can be used. The manufacturer recommends that you use caution during application because the spray can cause damage if it comes into direct contact with foliage.

  • Asked by Aball from Annapolis, Maryland
    08/04/2019
    Q
    When I am finished using Tenacity Herbicide, how do I dispose of it?
    Curious if I dump this down the drain, on the lawn, in a storm drain, or if it needs to go to the dump. I live close to a creek which dumps into a river.
    A

    We do always recommend that only mix the amount of Tenacity Herbicide you can use at a time.  To dispose of any remaining you would not pour down any drain, but can use to go over some of the areas you were treating or you can pour into the dirt right next to the foundation of the home to prevent any run off to the nearby creek.

  • Asked by Rodolfo from Yakima, Wa
    09/15/2016
    Q
    How do I apply Tenacity only to a couple of small Patches of bent grass on my lawn?
    How do I apply a small amount. What is the mixture ratio of water and tenacity to cover this small area - both patches are maybe 8 feet square?
    A

    According to the Tenacity product label you will need to mix 1 tsp of product + 3 tsp surfactant with 2 gallons of water for spot treatments applied at a rate of 1 gallon per 1,000 sq ft. If you can acurrately measure a smaller amount it could be halved to do 500 sq ft but anything smaller would not be recommended.

    Q
    How often do I apply Tenacity to healthy lawn to keep the bentgrass out?
    I have killed the Bentgrass with Tenacity and reseeded. New grass is now growing in those areas. It is mid-October in NW Oregon. How often should I apply Tenacity to prevent the Bentgrass from coming back?
    A
    You can reapply Tenacity Herbicide when the newly germinated turf has been mowed two to three times or four weeks after emergence, which is longer. Repeat applications can be done after two to three weeks for continued post emergent weed control.

  • Asked by Al from Waterford, Michigan
    10/19/2016
    Q
    How soon can I reseed after applying Tenacity Herbicide to kill bentgrass?
    I applied 3 applications in two-week intervals. The lawn was 80% bentgrass. Is it getting too late in fall to seed?
    A

    Per the product label on Tenacity Herbicide, apply at grass seeding or close to seeding for best preformance. If you are not close, meaning within a week of application, then you would need to wait 6-8 weeks to re-seed, As for your questions is it too late ot re-seed, we recommend you contact a master gardener in your area or your Local Extention Office to get more information on that.

    Q
    Is Tenacity Herbicide Safe on Spruce Trees?
    Can I spray this product as both an herbicide and pre emergent in and around blue spruce ornamental trees (weeds emerging through bottom branches)? If yes, what is a safe application rate?

Tenacity will also act as a pre emergent for listed weeds.

    Q
    Will Tenacity Herbicide kill wire grass in our tall fescue?
    A

    Wiregrass is a form of bermudagrass.  The product label states that bermuda grass is sensitive to Tenacity but it would not be recommended as a product specifically used to kill it.  Fusilade II can be used to get rid of bermuda grass in tall fescue.  Please be advised that bermuda grass is extremely difficult to control and you will likely need to make several applications.

  • Asked by Jack from Harrison City, Pa. 15636
    08/13/2019
    Q
    How do I mix Tenacity Herbicide?
    I want to broadcast spray my entire lawn. 4,000 sq ft Thanks.
    A

    Tenacity Herbicide calls for 5 to 8 oz of per acre, unless treating St. Augustine turf grown from sod, you would use 4 oz per acre. If you plan to use Tenacity at low rates of 5 oz per acre then you would use 0.11 oz per 1000 sq/ft or  0.45 oz per 4k sq/ft. If you want to use the high rate of 8 oz per acre then you would use 0.18 oz per 1000 sq/ft or 0.72 oz per 4k sq/ft. Be sure to use at least 1 gallon of water per 1000 sq/ft that you treat, and mix your non-ionic surfactant into the tank at the rate of 2 teaspoons per gallon of water. Spray foliage of target weeds until wet but not until the point of runoff. If a reapplication of Tenacity is needed, you can reapply after 2-3 weeks from your initial application.
