    Tenacity is a systemic preemergence and postemergence herbicide for the selective contact and residual control of weeds in turfgrasses.

    Q
    After spraying Tenacity Herbicide, when the weeds turn white, do you pull them or just reseed?
    I was told I had nimblewill in my yard. It was a large portion with green blades and brown plus some other weeds. I purchased tenacity from you and applied it. The areas that were brown and green haven't turned white but the are scattered portions of other weeds that have. Does that mean anything? Also, am I supposed to pull them after they turn white and reseed?
    A

    After spraying with Tenacity Herbicide, 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. We would not recommend …

    Q
    What is the amount of Tenacity per gallon for application on a St. Augustine lawn per 1,000 sq ft?
    The label only discusses per acre application. How do you break that down per gallon in a sprayer or per 1000 sq ft application? I am using a 4 gallon backpack sprayer.
    A

    According to the Tenacity product label for smaller applications, you will need to mix 0.5 tsp of Tenacity and 1.5 tsp of surfactant to one gallon of water covering 1,000 sq ft.

  • Asked by Marlin from Evansville, In
    07/25/2015
    Q
    Would it be OK to apply Tenacity Herbicide in the evening, after it cooled down for the day?
    No application above 80 deg. Does that mean don't apply anytime when temps are consistently above 80 or just not at the exact time it's that hot? Would it be OK to apply in the evening, after it cooled down, even though it gets that hot during the day? Or should I wait a couple of months until consistently cooler temperatures set in?
    A

    When the label states that no applications should be made when temperatures are above 80 degrees, this means that the product should not applied when it is 80 degrees and above. Tenacity Herbicide can be sprayed in the evening time and/or early morning hours.

    Q
    How soon can I reseed after using Tenacity Herbicide?
    Assuming it kills creeping bentgrass in a few weeks, or maybe longer if more applications are needed, how long should I wait before reseeding?
    A

    Tenacity Herbicide can be used at the time of seeding or right after for most grass types. Fine fescue is the only grass seed that should not be used at the time of application. It is recommended that you wait 2-4 weeks after an application of Tenacity Herbicide to reseed with fine fescue.

    Q
    Can Tenacity Herbicide be stored after mixing with water and surfactant for use at a later date?
    I mix Tenacity, a surfactant, and water in one gallon batches to spot treat my lawn using a pump sprayer. I frequently have part of a mixture left over when I finish treating. Can I store it for two weeks and use it for a follow up treatment?
    A

    Tenacity that has been mixed with water and a surfactant should be used within 24 hours of mixing and then discarded. If it is in its original container and stored away from extreme temperatures, it will have a three year shelf life unmixed.

    Q
    If it is 70 degrees in the morning and will get up to 95 in the afternoon, can I still apply Tenacity Herbicide?
    I noticed a question about temperature and application of Tenacity, you stated it can be applied up to 80 degrees. Is that during application?
    A

    When mentioning Tenacity Herbicide and temperature, we are referring to the temperature at time of application. If it gets above 70 degrees after your application has dried, that is okay.

    Does Tenacity control creeping charlie?

    Yes, 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.

  • Asked by Mike from Wilton, Ct
    07/12/2015
    Q
    How long does Tenacity take to kill plants?
    I used the recommended spot treatment amounts of Tenacity with surfactant. Even applied 2nd treatment to most of it. Most leaves turned white as expected but not all and the weeds did not die. Now all it of appears to have recovered as most of it is a normal green. What do I do now? Try again? I am worried about applying too much but the nimblewill will not die but turned white.
    A

    The foliage of weeds treated with Tenacity cease growth after the application, then turn white (loss of chlorophyll), so death may take up to three weeks. A repeat application is required after two to three weeks for improved postemergence weed control.

    09/25/2015
    Q
    How long after apply Tenacity Herbicide can the grass be cut?
    Answer to Wayne is 2-3 days. Answer to Nancy is 5-7 days. Big difference! Also after applying tenacity when can the lawn go back to its watering cycle. Both of my questions, cutting and watering either pre or post, strive to allow the best conditions to get the best per application. I must have missed reading these things in your attached literature. Thank you. Lastly when can I continue with fertilizing the lawn after an application?
    A

    When using Tenacity Herbicide or other post-emergent herbicides, you should not mow at least 2 days before or 2 days after applying the product. You should avoid spraying on newly germinated turgrass plants, and wait until newly germinated turf has been mowed 2 times or 4 weeks after emergence (whic…

    Q
    Is it possible to use a hose end sprayer to apply Tenacity?
    A

    Tenacity should not be applied with a hose end applicator. Tenacity if not applied evenly across the yard can temporarily whiten your lawn and cause you to not see full control of the weeds you want to eliminate. Also most hose end sprayers will not dial down to the small amounts needed per 1000 sq/…
