    Q
    I keep bees in my back yard. Can I use Tenacity on the bentgrass without harming my bees?
    A
    Tenacity Herbicide could potentially harm bees if they come in contact with the treated area. We recommend contacting your local cooperative extension office and speak with the master gardener in your area for advice on product that will not harm bees.

    Q
    Nimblewill and Crabgrass Post Emergent Treatment - Rain
    I want to do Post-Emergent Treatment of Nimblewill and Crabgrass cool season turf with mix of KYB, Fesue and Rye. What is the amount of time the Tenacity should dry before rain or irrigation? Should it be irrigated for Post-Emergent treatment? The overall area to be treated is 4300 sq ft. The weeds are dense in a 1600 sq ft area and then sparse (spot treat) through the rest of the turf . Is the dense weed area considered spot treatment, so that 1/2 tsp per gallon or is it consider large area treatment using the higher rate of 1 tsp per gallon ?
    A
    After treating with Tenacity you want the product to have at least 6 hours of dry time before any rain or irrigation occurs. You do not want/need to water after a post emergent application. We recommend using the spot treatment rate of Tenacity in the dense areas so as to not cause damage to your lawn. Tenacity is known due to its power to even with an accurate application to sometimes temporarily whiten the turf surrounding the weed areas. The color will normally return within 3-4 weeks so to minimize the chance of turf discoloration you will want to use the lower dose at first and be cautious to not overlap or too heavily apply the product. Please let us kow if you have any other questions.

    Q
    Is the application rate for a blanket spraying over entire yard the same as spot spraying with Tenacity?
    A

    According to the Tenacity product label you will need to mix 1 tsp of product + 3 tsp surfactant with 2 gallons of water for spot treatments. You will not apply more than 5-8 ounces of Tenacity per acre as a broadcast application. Please click on the product label link for mixing and applications according to the type of turfgrass you have.

    Q
    Does Tenacity control creeping charlie?
    A
    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. 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.

    Q
    I'm confused whether or not it will hurt new Kentucky Bluegrass seed?
    I've read the label but it say's it hurts Fescue's when seeding but it also says it suppresses Bluegrass, Annual Poa annua. I need this cleared up as I'm about to seed. I've already put 1 app of Tenacity down.
    A
    Kentucky Bluegrass (Poa pratensis) is different than regular Bluegrass (poa annua). It is true that Tenacity may reduce density of fine fescue seedings. Tenacity can be used on grass seed blends that contain less than 20% by weight of hard or fine fescue. It will not harm your Kentucky Bluegrass seeding. If you need more specific information on a turfgrass not mentioned on the product label you can reach the manufacturer at 866-796-4368.

    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.

    Q
    What is the shelf life of Tenacity?

    The shelf life on most liquid herbicides all depends on how they are stored. If the product has been tightly sealed and kept out of sunlight and extreme temperatures, the shelf life is 3-5 years.

  • Asked by Mike from Groton, Ma
    04/21/2014
    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/ft that the Tenacity requires. Tenacity is best applied with some form of a pump/tank sprayer in even strokes without excess overlapping.

    According to the Tenacity product label you will need to mix 1 tsp of product + 3 tsp surfactant with 2 gallon of water for spot treatments, using 1 gallon per 1000 sqft.

  • Asked by Anne from Horsham, Pennsylvania
    05/06/2014
    Q
    Is it possible to apply Tenacity to a large area (one acre) with a hose-end sprayer?
    A
    It is not recommended to use herbicides in hose end sprayers. The problem with using the hose end sprayer for the Tenacity Herbicide application is that they are not very accurate and you can wind up dispensing more/less product than needed in a given area which can lead to less than desirable results.

    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.

  • Asked by Claudia from Ness City, Kansas
    07/08/2014
    Q
    I bought Tenacity to kill some small spurge in Buffalograss. What strength should I use in a one gallon spray
    It doesn't seem to be killing it. Should I use it stronger or more often? At first I used it 1/2 tsp in 1 gallon with 1/2 tsp surfactant
    A
    Tenacity Herbicide does not list spurge as a weed that it controls on the product label so that would be why it is not working for this weed.  You would have better success using a product that specifically lists spurge on the label such as the Speedzone Southern.

  • 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.
