  • Asked by Scott from Saint Joseph, Michigan

    Q
    How do I get rid of Bermuda Grass in my yard?
    I bought Tenacity from your company hoping it would do the trick. We have Kentucky Blue Grass and we live in Michigan. Maybe it's to soon to tell since I applied two applications in the last two weeks.
    A

    The product label states that Bermuda grass is sensitive to Tenacity but it would not be recommended as product to eliminate it since it is not labeled for this use.  Turflon Ester would be a better option for removing bermuda from cool season turf.

    Q
    Can I speed up the three spraying intervals for Tenacity to 10 days instead of 2/3 weeks?
    Trying to get plenty of time for aeration and Fall seeding.
    A

    No, Tenacity Herbicide must be used per labeled instructions or it could cause damage to your lawn if used otherwise.  Applying Tenacity Herbicide more frequently than the label allows could cause unnecessary stress to your turf or worse, it could kill your desirable turf.

    Q
    Can I put down lime between Tenacity treatments?
    I have applied 1 application of Tenacity 1 week ago and plan on waiting another week or two before applying another application. Am I able to put down lime in the yard between treatments or will this effect the ability of Tenacity to work?
    A

    You can reapply Tenacity Herbicide after 2-3 weeks for post emergence control of actively growing weeds for best results. There should not be an issue applying lime after the application. We would encourage you to get a soil test to determine the pH level of the soil you are treating also. This can be done at your local cooperative extension.

    Q
    How long should I wait until I can put a winterizer on my lawn after an application of Tenacity Herbicide?
    A

    There is no specific time that you need to wait after using an herbicide like Tenacity before you can apply a fertilizer. As long as the turf is healthy and you are following the directions on the product labels for what you are applying, then you should not come across any problems.

    08/25/2019
    Q
    Can I spray Tenacity over all my lawn in the fall for pre-emergence?
    I need pre-emergence selective herbicide for fall and spring before weed germinate. Is Tenacity can be used for this purpose to broad cast the whole yard of around 7000 square feet? Is this chemical very toxic for human and pet? Can it be used anytime in the year no matter what temperature out there?
    A

    Tenacity Herbicide can be used as a broadcast application for pre-emergent control of the listed weeds on the label.   It can be used anytime of year depending on target weeds.  As long as you keep pets/children out of the area while you treat and until the product has had time to completely dry or settle it is safe for pets and people to return and resume normal activity

    new lawn loaded with poa now seed heads everywhere I also do have some issues with bent grass I have used tenacity for it is the a product to control the poa annua pre or post apps spring and fall to kill and control?????
    A
    Tenacity Herbicide is labeled for both pre and post emergent control of selective weeds. The label specifically states that bentgrass and poa annua are sensitive to this product and will likely kill it. With poa annua, it is labeled for pre-emergent control only. Tenacity will kill bent grass both pre and post emergently.

  • Asked by Jacky from Elk Grove, Ca
    05/02/2019
    Q
    Are these the correct Pre-Emergent and Post-Emergent applications with Tenacity Herbicide?
    I wanted to confirm if I am correct with the following: Pre-Emergent -- when using as pre-emergent, you spray your entire lawn. Post-Emergent -- When using as post emergent, you will spot spray the weeds. Thank you,
    A

    In general, this is correct. Tenacity is typically only used as a pre-emergent when seeding or over-seeding with turf types that are listed as tolerant on the product label. For post-emergent weed control, you should just spot treat to avoid whitening on your desirable turf.

  • Asked by Marc from Chesaning, Mi
    06/23/2018
    Q
    Can Tenacity be tank mixed with 2-4D?
    A

    Per the manufacturer, " Tenacity has been tested in tank mixtures with Barricade 65WG Herbicide (prodiamine), Vanquish® (dicamba), Turflon® ester (triclopyr), Spotlight™ (fluroxypyr), Quicksilver™ (carfentrazone), Basagran® (bentazon), Princep® (simazine), and AAtrex® (atrazine) for safety and efficacy on turfgrasses. Tenacity must be applied at reduced rates (4 fl. oz./A or less) if tank mixed with atrazine, bentazon or simazine. Other tank mixture partners may be safe but have not been tested. Turf managers wanting to tank mix Tenacity with other herbicides should test on a small basis for compatibility, safety and efficacy before treating large areas. See product labels for directions and precautions."

    Q
    Can I mix the Tenacity Herbiicide with Eagle 20EW Specialty Fungicide, Dismiss Turf Herbicide & Talstar P (Talstar One) for turf?
    A

    It is not recommended to mix certain insecticides, herbicides, or fungicides with Tenacity Herbicide.  You should wait to apply insecticides 7 days after treating with Tenacity Herbicide to avoid potential turf injury. Other ingredients in the fungicides or herbicides would be fine to use at the same time if there are no resttrictions on the product label.

    05/01/2017
    Q
    When is it too late to apply Tenacity as a pre-emergent for crabgrass control?
    A

    Tenacity Herbicide can be applied any time before the weeds start to germinate. Weeds absorb Tenacity as they emerge from the soil. For the best time to apply pre-emergents in your county we recommend contacting your local cooperative extension office here. Crabgrass seeds will start to germinate when soil temperature are around 55 degrees, so you need to apply it before you have those temperatures for best results.
