    Q
    Did I just kill my garden plants by spraying them with Tenacity Herbicide?
    I have a lot of ornamental (sea) grasses, and just sprayed Tenacity over all my beds, in an effort to suppress an overgrowth of weeds. I also have seedling Crepe Myrtle bushes. Should I be worried, and is there anything that will counter-act Tenacity on a mis-sprayed plant?
    A

    Tenacity Herbicide should not be used around or on desirable ornamentals and/or trees or used within 3 feet of trees or ornamentals.  Unfortunately, there is not a product that can be used to reverse the effects of the Tenacity sprayed on intolerant plants.

    Q
    How many times per year can I spot treat using Tenacity?
    A

    There is not a specific limit on the number of spot treatments that you can make using Tenacity Herbicide as long as you do not exceed the annual maximum of 16 oz Tenacity per Acre or per crop. Typically you would wait at least 2-3 weeks between applications to the same areas. Be sure that you follow all the product label instructions as far as timing with seeding and other restrictions.

    Does Tenacity kill poa annua?
    A

    Tenacity Herbicide is not labeled to control Poa Annua/Annual Bluegrass as a post emergent application.  The label only states that it could cause injury to it if sprayed.  It is only labeled to be used to suppress poa annua when used as a pre-emergent.

  • Asked by Annette
    07/03/2017
    Q
    What can you put in the mixture of Tenacity Herbicide to turn the plant color until it dies?
    A

    We are not aware of anything that can be added to Tenacity Herbicide to cause the plant color to change as it dies and it already causes a color change itself.  Per the product label: 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. A non-ionic surfactant should be added in postemergence applications

  • Asked by Sidney from Wellington, Ky
    05/21/2019
    Q
    When do you apply Tenacity to the lawn - now, spring, or summer?
    A

    When you apply Tenacity Herbicide will depend on how you are using it. When using Tenacity as a post-emergent herbicide, you should spot treat target weeds when they are young and actively growing, which may be in spring, summer, or fall. Generally, you do not want to use any post-emergent herbicides when temperatures are over about 85 - 90 degrees since your desirable grass will be more sensitive and the target weeds will not be growing when it’s that hot. Tenacity should be used as a broadcast application pre-emergent when renovating lawns listed as tolerant on the product label. Since these are primarily cool-season lawns, this application is generally done in the fall.

  • Asked by Richard from Dalton Gardens, Id
    10/30/2019
    Q
    Will Tenacity Herbicide kill yellow iris around my pond?
    Digging iris does not rid my pond or area of it. It is now a weed and I tried roundup but it wasn't effective.
    A

    Tenacity is not labeled to control undesirable ornamental plants, although it may harm them if sprayed accidentally. You will need to remove physically all the parts of the iris - including the rhizomes in the soil – in order to prevent these plants from regrowing the following year. You can use a glyphosate product such as RoundUp QuikPro to kill the above ground plants, but you will need to remove the rhizomes after spraying. This article has easy-to-follow directions on this treatment, which is best done in the fall.

    If I apply Tenacity do I need to wait a certain amount of time before I bringing some topsoil to level out my lawn and add organic matter to the soil?

  • Asked by Sam from Winston Salem, Nc
    04/01/2019
    Q
    Can Tenacity and glyphosate be mixed together
    I know this might be strange question but looking for the benefit of tenacity’s pre-emergent characteristics and the immediate and total kill of glyphosate.
    A

    We would not suggest mixing Tenacity and a glyphosate product as there would not be much benefit in doing so. You could mix a pre-emergent like Dimension 2EW or Prodiamine 65 which would cover many broadleaf and grassy weeds.
