Trin-Pac Select is a turf growth regulator that slows the top growth of the plant. By limiting the vertical growth, the energy in the plant is redirected to strengthening the root structure as well as prompting greater lateral growth. Using Trin-Pac Select will result in a reduction in the frequency of mowing and the amount of grass clippings, while increasing the color, quality and density of the turf. Trin-Pac Select is effective only through absorption and not by plant uptake through the soil.
