a plant growth regulator. Plant growth regulator. Used for control of preharvest fruit drop, flower induction and fruit thinning in various crops such as apples, potatoes, olives and citrus fruits 1-Naphthaleneacetic acid (NAA) is a plant hormone in the auxin family. It is a rooting agent and used for the vegetative propagation of plants from stem and leaf cutting. It is also used for plant tissue culture. NAA does not occur naturally. Under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), products containing NAA require registration with the Environmental Protection Agency (EPA) as pesticides. (Wikipedia)
