  • Asked by Len from Wyoming, Pa
    03/02/2016
    Q
    What is "broadcast application" and when is it preferable to use spot application with Tenacity Herbicide?
    A

    When using Tenacity Herbicide a broadcast application would be considered spraying over the entire lawn area. A spot treatment is used when you only have certain spots or areas that need to be treated versus the entire lawn. For most post-emergent applications with Tenacity, you will just spot treat to avoid whitening the desirable turf. Please follow the specific directions on the product label for your needs.

  • Asked by Bill from Minneapolis, Mn

    Q
    Does Tenacity Herbicide have any effect on quackgrass?
    I know the product is not listed for quack grass, but when I sprayed a patch, while spraying for bent grass, the tips of the leaves turned white. Would additional spraying have any beneficial effect?
    A

    Since quackgrass is not on the label to be controlled by the Tenacity, we cannot recommend you use it for this application. We do, however, carry Certainty, which is a selective post-emergent herbicide like Tenacity, that does have Quackgrass listed on the label under weeds controlled. You can see the dilutions and what grasses are tolerant of Certainty on the product label.

    Q
    When can I reseed after applying Tenacity?
    A

    Tenacity Herbicide should be applied at grass seeding or close to seeding for best results. If you are not close, meaning within a week of application, then you would need to wait 6-8 weeks to re-seed.

  • 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
    Will Tenacity Herbicide kill orchard grass?
    A

    Tenacity Herbicide is not labeled to control orchardgrass. Unfortunately, we do not know of any selective herbicide that will kill orchardgrass without harming your desirable turfgrass.  It is usually recommended to spot treat the orchard grass as much as possible with a non-selective product like RoundUp QuikPro, and then replant in those areas in a couple of weeks when the orchard grass is gone.

  • 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 Shaun from Salisbury, Nc
    05/17/2019
    Q
    Can Tenacity be used under a tree canopy? Can't find any info on this.
    I really need a post-emergent herbicide for use under some oak trees on typical lawn weeds (dandelion and clover etc...). My lot is small and the tree drip lines extend past my lawn (my whole lawn is under the massive tree canopies). So anything I use is going to be near surface roots. I've seen a neighbor knock the leaves out of his trees one year with Speedzone. That is a scary thought considering the cost of removing a tall oak tree.
    A

    Tenacity Herbicide states on the product label: Avoid applications over the top of exposed roots of trees and ornamentals.  Just about all herbicides are going to have the restriction that applications should be kept out of the dripline of desirable trees.  The best you could do is carefully spot treat the weeds themselves and not broadcast in these areas.

  • Asked by Ronnie from Charlotte
    12/15/2019
    Q
    Is Tenacity Herbicide supposed to be a white color like milk?
    I wonder if it is out of date. Is it supposed to be clear? Mine looks like milk, and I see no sign of it killing anything after one week.
    A

    According to the Safety Data Sheet, before Tenacity Herbicide is diluted, it should have a beige to tan liquid appearance. If the product has been tightly sealed and kept out of sunlight and extreme temperatures, the shelf life is 3-5 years. When using Tenacity, 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.  A non-ionic surfactant should be added in post-emergence applications. Please review the product label for more information about this product and applications.

    Q
    Will Tenacity Herbicide kill Bermuda grass in a Fescue lawn?
    A

     The product label states that bermuda grass is sensitive to Tenacity but it would not be recommended as a product specifically used to kill it.  Fusilade II can be used to get rid of bermuda grass in tall fescue.  Please be advised that bermuda grass is extremely difficult to control and you will likely need to make several applications.

    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
