    Q
    Will Tenacity kill seedling trees?
    I have a newly planted tree grove (last year) and there are many growing broadeaf weeds that are taking over.
    A
    Tenacity Herbicide is not labeled for trees so spraying around the trees could possibly harm them. We would recommend contacting the manufacturer directly for instructions on spraying around new trees. Here is the number: 866-796-4368.

  • Asked by Brenda from Port Hope, Mi

    Q
    What product do you recommend to kill Creeping Charlie in our lawn?
    I do want a product that is not harmful to our lawn grass. Thank you
    A
    Tenacity is labled 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 be sure to find out what type of turf you have and review the product label to make sure your turf is tolerant to this product.

    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.

    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.

  • 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.
