    Q
    Will Tenacity work on Pascopyrum smithii (Rydb.) western wheatgrass?
    I saw on label that it is OK?.... on Buffalo Grass
    A

    While Tenacity is labeled to be used on Buffalograss it is not labeled to control wheatgrass.  We are not able to find anything that is labeled to do so.  The best thing to do for this issue is to spot treat with a glyphosate based product like GlyPhoSel Pro and reseed/sod the treated area.

    Q
    Can I use my hand held weed wiper with Tenacity in it?
    A

    We are not sure if Tenacity Herbicide can be applied with your handheld weed wiper. If you can apply the labeled amount over 1000 square feet with water, we do not see an issue. It would be best to also consult with the manufacturer of your Weed Wiper.

  • Asked by Matt from Charlotte, Nc

    Q
    How do I eliminate Nimblewill in St. Augustine?
    I am trying to find out the best and most reasonably priced way to get rid of nimblewill that has started popping up. I know st Augustine is very sensitive and I have already bought blideside to control most of my broad weeds, but it doesn't seem to work on nimblewill. I know tenacity will work but again its on the more expensive side. I was seeing if there was another option you could recommend. I live in Charlotte NC.
    A

    Tenacity is labeled for post-emergent control of Nimblewill. Per the product label, you may need a second application after 2 to 3 weeks. Apply to young, actively growing weeds, and be sure to use a surfactant such as Southern Ag Non-Ionic surfactant for post-emergent applications.  Your other option would be to use a non-selective herbicide such as Roundup to spot treat the Nimblewill to kill it directly, and then replant St. Augustine in those areas.

    Q
    Will Tenacity Herbicide kill evergreens if used on the surrounding grass?
    A

    The product label for Tenacity Herbicide recommends that you avoid applications over the top of any exposed roots of trees and ornamentals. We would recommend keeping Tenacity outside the dripline of desirable trees for safety.

    Q
    Do I reseed during first or second application of Tenacity?
    I see instructions here saying that I should reseed at the same time as I apply the Tenacity, but also that I should reapply Tenacity after 2-3 weeks. Should I reseed during the first application or during the second?

  • Asked by Greg from Green Bay, Wi
    07/18/2018
    Q
    To kill extensive bentgrass, is it best to apply the first application of Tenacity as soon as the grass begins to come back or wait until the grass is completely back and fully green?
    All bentgrass is dormant now. Wisconsin climate. Looking to apply late summer/early fall.
    A

    Your first application of Tenacity Herbicide in the fall to control bentgrass will be most effective just before the onset of new growth. You can then apply at 2-3 week intervals. You do not want to wait for it to be fully re-established to start treatment.

  • Asked by Mark from Palo Alto, Ca
    09/14/2018
    Q
    What is the best time to use Tenacity on nimblewill?
    Have applied Tenacity once three weeks ago, but if September - February is nimblewill dormancy, should the remaining two or three applications wait until say March 2019?
    A

    Per the label for Tenacity Herbicide, it is best to treat nimblewill with 2-3 applications which are 2-3 weeks apart. If the nimblewill is still green, then you can go ahead and retreat now. If it is already dormant, then it would be best to wait until it is green again to treat with herbicides.
