  • Tame Your Turf

    T-NEX 11.3 ME reduces the frequency of mowing and the amount of grass clippings by regulating the growth of turfgrass. Full growth regulation by T-NEX begins within 3 to 5 days of application.

    T-NEX can be applied to well-maintained turf on golf courses and commercial sod farms. T-NEX reaches the growing point by foliar uptake. Application should be completed at least 3 hours before irrigation or rain. Areas treated with T-NEX should continue to receive regular maintenance, including irrigation, fertilization and weed, disease and insect control when necessary, as recommended for quality turf.


    Apply T-NEX no more than once every 4 weeks to actively growing turf. Apply only at the rates shown in Table 1 or as detailed on the product label. At these rates T-NEX provides approximately 50% growth inhibition.
