High-purity sodium naphthalene acetate is a growth hormone-type plant regulator that enters the plant through leaves, young epidermis, and seeds, and is transported via the nutrient flow to vigorously growing parts (growth points, young organs, flowers, or fruits). Sodium naphthalene acetate significantly promotes the development of root tips (rooting powder), induces flowering, prevents flower and fruit drop, facilitates the formation of seedless fruits, promotes early maturation, and increases yield. Additionally, it enhances the plant's resistance to drought, cold, diseases, saline-alkali conditions, and dry hot winds. Tests conducted in Japan, Taiwan, and other regions have shown that the efficacy of high-purity sodium naphthalene acetate far surpasses that of ordinary sodium naphthalene acetate.
