Used as a plant growth regulator to promote root development in cuttings and tissue culture applications. Enhances rooting in a wide range of ornamental and agricultural plants when applied at low concentrations. Commonly used in horticulture for vegetative propagation of difficult-to-root species. Also utilized in laboratory settings to induce callus formation and support somatic embryogenesis in plant cell cultures.

In agriculture, it aids in the production of seedless fruits through parthenocarpy, increases fruit setting rates in certain plants, and prevents premature flower and fruit drop.

Its sodium salt form improves water solubility, making it suitable for use in liquid formulations and nutrient media.
