  • Applications

    Trinexapac-ethyl (CAS 95266-40-3) is a plant growth regulator in the gibberellin biosynthesis inhibitor class, used in agriculture and landscape management to control height and reduce lodging. Typical applications include turfgrass management on golf courses, athletic fields, and lawns to reduce shoot elongation and improve upright appearance; growth regulation in cereals and grains to lessen lodging and improve crop stand quality; height control in ornamentals, nurseries, and outdoor landscaping to achieve a more uniform plant architecture; and urban landscape maintenance to sustain balanced growth. Applications are typically delivered via foliar spray formulations and are subject to local regulations and formulation limits.
