    03/28/2019
    Q
    What application rates should be used when combining Tenacity with Barricade pre-emergent weed control?
    A

    Tenacity Herbicide would be mixed at the same rates listed on the label on your turfgrass for using solo when tank mixing with Barricade.  You would only used reduced rates if mixing with atrazine, bentazon or simazine.

  • Asked by Sam from Winston Salem, Nc

    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.

  • Asked by Jacky from Ca
    05/01/2019
    Q
    When applying Tenacity Herbicide as a post-emergent how does it work? Do I spray the weeds directly or broadcast the entire lawn?
    Can I reuse?
    A

    When Tenacity Herbicide is used for post-emergent control of weeds the weeds are sprayed directly. According to the product label, when used postemergence, susceptible weeds absorb Tenacity through foliar contact and soil absorption. 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 Kent from Lincoln, Nebraska
    05/02/2019
    Q
    Will Tenacity kill thin-bladed fescue?
    I'm starting a new lawn and that's the type of grass I'm going to use. I don't want to kill it before I get anything growing.
    A

    Tenacity Herbicide should not be used if the seed you are putting down is more than 20% fine fescue. If you have a fescue blend that is less than 20% fine fescue, then it should be safe to use Tenacity before or at the same time as seeding. Please refer to the product label for full application instructions.

  • 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.

    Q
    Best times to apply Tenacity for zone 6b
    I want to use Tenacity for Nimblewill as a broadband post emergent now and later as a pre emergent to control re-infestation. Right now it is brown/tan in color in my lawn. Is it too late in the growing season to use it now?
    A

    Broadcast treatments would be recommended if you are needing to actually treat the entire lawn for pre-emergence, if you are only needing to treat small areas or use as a post emergent then you can spot treat. Consult your local Cooperative Extension Service for more specific applications timings for your local area. Their contact information can be found by clicking the link below.

  • Asked by Francis from Columbus, In
    07/19/2014
    Q
    What is the prefered PH? Also, the tank mixed 1/2 life?
    A

    There are certain products that are susceptible to problems with high pH balances in water. If a product label does not specifically address this issue it is because this particular product does not usually have any issues with pH.  The product label for Tenacity does not list anything regarding pH levels.

    Once mixed with water you should use the product within 24 hours.

  • 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.
