  • Asked by Kim from Palestine Texas
    09/01/2021
    Q
    Is there a maximum soil temperature to apply T-Nex Plant Growth Regulator?
    My soil temp is 96 degrees, I am wondering if that is to hot to apply this.
    A

    There not a specific temperature restriction for T-Nex Plant Growth Regulator only that it should be applied when the turf is actively growing. Generally that is when you are still mowing the lawn. 

    Lower rates should be used when when turf is going dormant due to high or low temperatures, or lack of moisture.

    06/28/2021
    Q
    When should I apply T-Nex Plant Growth Regulator?
    I just added fertilizer to my lawn. It's well established and about to add micro nutrients, etc. The yard has had nothing done to it for years. It's Saint Augustine I live in the gulf coast of Texas. I need to spray RoundUp for Southern Lawns. To get rid of weeds. So when should I add the Growth Inhibitor. I spent years confined to bed. But now able to walk again. PTL
    A

    T-Nex Plant Growth Regulator should be applied when the lawn if actively growing and will last for 8 weeks. Depending on the type of turfgrass you have, the application rates should be adjusted based on the grass height at application. Please view the Application Rate Table on the product label for application rates for your turfgrass. The lower the height of cut of the particular turfgrass species, the less material is required to provide the desired turf growth regulator effect.

  • Asked by William from Omaha, Ne
    10/12/2021
    Q
    How soon after seed germination can I apply T-Nex plant growth regulator?
    Mostly KBG existing lawn. Used T-Nex on September 6th. Mowed at 1.5" and overseeded September 10th. Good germination on September 16th. New grass is as tall or taller than existing grass as of October 12th. How soon after germination can I apply more T-Nex?
    A

    The T-Nex Plant Growth Regulator can be applied now based on the timeline you have given for your seeding and mowing, and the height its currently at. Once your new grass gets to the height of the existing grass and you've mowed it to where they are pretty even, you can put the T-nex on the lawn without any issue and it will give the result you are looking for from the lawn.

  • Asked by Hermilio from Champaign, Illinois
    06/04/2021
    Q
    Can T-Nex Plant Growth Regulator be mixed with Propiconazole 14.3?
    A

    You could potentially mix a PGR such as T-Nex Plant Growth Regulator with a fungicide like Propiconazole. Be sure you are using the correct application rates for both. We also always recommend a small jar test first to check compatibility before mixing a larger tank. Also be sure there is good agitation if you are using a larger capacity sprayer.
