  • 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    I wonder if it is out of date.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.

  • Asked by Victor from Richland, Wa
    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

  • Asked by Robert from Ellicott City, Md
    10/04/2019
    Q
    How do I apply Tenacity when the nimblewill has gone to seed?
    We've had a drought the past month (September/early October 2019) in the Baltimore/Washington DC area and the nimblewill has gone to seed (and my lawn service just arrived to mow my yard as i started typing this). I was pulling them but there is just too much and the ground is dry as a bone.
    A

    Tenacity Herbicide is applied to nimblewill when it is actively growing, and should be applied when temperatures are between 65 and 85 degrees.  You should make your application when no rain is in the forecast for 24 hours, and you should not mow 2 days before or 2 days after your application.  It is applied at the rate of 1 teaspoon of Tenacity, 3 teaspoons of surfactant, in 2 gallons of water per 2000 sq ft.

    10/14/2019
    Q
    Can Tenacity Herbicide be used in lawns in PA?
    I haven't seen in on store shelves and my local Ag dealer had not heard of it.
    A

    Tenacity Herbicide can be shipped and used in Pennsylvania. It can safely be applied to Kentucky Bluegrass, Centipedegrass, Buffalograss, Tall Fescue, Perennial Ryegrass, Fine Fescue, St. Augustine Grass (grown for sod only). This is a professional grade product, so you will not find it on the shelves of any big-box stores.

  • Asked by Ray
    03/30/2020
    Q
    I applied Tenacity on my turf grass during the first week of March. At least 90% of the lawn is light yellow
    In color 3 weeks later. How long would it be before turf returns to green? I live in NJ.
    A
    Yellowing or whitening of the turf after a broadcast application of Tenacity Herbicide is caused by the loss of chlorophyll. The product label states, "Tenacity may cause temporary whitening of turfgrass foliage. In general, symptoms appear five to seven days after application and last for several weeks. A repeat application to the same site causes less whitening of the plant tissue."

    Q
    I have crab and quack grass among perennial plants such as day lilies, will Tenacity work?
    A
    Tenacity is not labeled to kill Quackgrass. We recommend using a glyphosate product like Glyphosel Pro and spot treating. You can also use a product a selective herbicide like Certainty if you have warm season grass. Please make sure to always review the product label to make sure you are using the right product and mixing ratio for your needs.

  • Asked by Scott from Saint Joseph, Michigan
    05/08/2014
    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.

    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 Chau from Derry, Nh

    Q
    Should I use a surfactant when applying Tenacity Herbicide to a newly seeded lawn?
    Trying to restore my lawn and aerate/seed this past Saturday 9/3/2016. Waiting for my order of Tenacity and Surfactant to arrive sometimes this week. Should I use both products and apply to the new lawn even though it's a week after seeding? Also should I use surfactant with it for pre-emergence or is that only for post? Thanks in advance!
    A

    It is safe to apply Tenacity Herbicide at or near seeding for most types of turfgrass for pre-emergent control. You should avoid spraying Tenacity on newly germinated turfgrass plants. Please refer to the product label for complete application instructions. You would only need to use a surfactant when applying Tenacity for post-emergent weed control.

    10/31/2016
    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.

    Q
    Can I kill rye grass with Tenacity Herbicide? I live in the Northeast.
    A

    No, Tenacity Herbicide will not eliminate ryegrass.  If you want to eliminate ryegrass in cool season turf, we would recommend using Turflon Ester Ultra. The mixing rate is 3/8 - 3/4 oz. per 1,000 sq. ft.

  • Asked by Jack from Harrison City, Pa
    08/14/2017
    Q
    Will I get better results if I cut my grass short before applying Tenacity?
    A

    This will depend on the target weed you are dealing with in the lawn.  If you have a thick lawn that would prevent contact with the target weed you should mow for better contact before applying Tenacity.  It is recommended not to mow within 2 days before or after applying a herbicide.
