  • Asked by Ray

    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
    Do you recommend Tenacity for fall application to Michigan grass?
    My yard is being overtaken with Creeping Charlie and wild violets (along with numerous other weeds). Thought if I applied this now, in the spring I could re-seed

    The best temperature range to apply most herbicides, including Tenacity, is between 65-85 degrees. For the best specific application times for your region, we recommend contacting your local extension office directly and speaking with the Master Gardener.

  • Asked by Charlotte from Germantown, Tn
    03/05/2016
    Q
    Will Tenacity Herbicide harm monkey or mondo grass?
    I have mondo grass as a ground cover with many weeds. What can I use to kill weeds and not the grass?
    A

    Tenacity Herbicide is not labeled as safe for use around Mondo or Monkey Grass. Surflan has been used for pre-emergent control of broadleaf weeds in Mondo Grass and for post-emergent control, Sedgehammer is commonly used. Please refer to the product lable for instructions and applications rates.

    Surflan - Preemergence weed control when applied to established ornamental plants before weeds have emerged. This product performs better with incorporation after application with irrigation, rainfall or light tillage.

    Sedgehammer - Apply in landscaped areas with established woody ornamentals. Do not apply over-the-top of flowers, ornamentals, shrubs or trees.

    Q
    How soon after a pre-emergent appication of Tenacity can I apply a post-emergent spray of Tenacity?
    A

    After further information from the manufacturer they have verified that to making a pre-remergent application with Tenacity you will need to apply a post emergent application once you detect germination of the weed itself. Syngenta recommends to apply no more than 3 application per year.

    Q
    Can I now do my second round of Tenacity Herbicide on new grass?
    I got one round of tenacity on my lawn then i aerated & reseeded 3 weeks ago. I fixed some large bare spots as well. I have new grass growing, but I see more weeds and clover and Crabgrass coming back. Can I now do my second round of Tenacity on this new grass. I'm starting the win the battle looks like, but Crabgrass is still hanging in there on about 30 % of total lawn.
    A

    If you have already seeded, then you do not want to apply Tenacity Herbicide to the newly seeded turf until is has been mowed two times or four weeks after emergence (whichever is longer) before making a postemergence application.

    Q
    Any application restrictions for lawns in N.Y. State with Tenacity Herbicide??
    How early in the Spring can you can you spray in this climate? How damp or wet should you spray to insure proper coverage?
    A

    Tenacity Herbicide is not restricted in the state of New York.  It can be applied when the soil temperature reaches 55 degrees Fahrenheit. This should be broadcast across the lawn in areas where you are wanting to prevent weeds. Be sure to water the product in 0.5 inches to activate it. This product can be applied right before it is going to rain. We normally recommend applying Tenacity in early to mid April in cool season areas.

    Please check out our Cool Season Lawn Guide for tips on how and when to use products in your lawn.

  • Asked by Frank from Cleveland, Oh
    07/03/2017
    Q
    Would it be helpful to apply a greater amount of non-ionic surfactant in the mix with Tenacity Herbicide ?
    The recommended mixture seems to be a ratio of 3 to 1. IS it possible or allowable to mix a greater ratio of the surfactant (say 5 to 1) in order to insure that more of the herbicide adheres to the creeping bent grass & various other weeds ?
    A

    According to the manufacturer, it is not advised to apply more than the recommended amount of the non-ionic surfactant. We advise you to use the ratio recommended on the product label.
