1-Naphthaleneacetic Acid (NAA, Naphthalene Acetic Acid, also named as α-naphthaleneacetic acid) belongs to a class of organic compounds of naphthalenes, which contain a naphthalene moiety of two fused benzene rings. NAA is a synthetic auxin plant hormone. It is used as a plant growth regulator to control preharvest fruit drop, flower induction and fruit thinning in various crops such as apples, potatoes, olives, and citrus fruits. It is used as a rooting agent and used for the vegetative propagation of plants from stem and leaf cutting. It is also used for plant tissue culture and as herbicide. Applied as a dust or spray it delays dissolution of the abscission layer, retarding the fruit drop. The effect of NAA on plant growth is greatly dependent on the time of admission and concentration. When used after four weeks, NAA stimulates shoot growth, while full-time use limits growth. When used in a 4-week pulse, adventitious root growth is greatly increased.

Chemical Properties:

Naphthalene Acetic Acid is a white crystalline solid, needles, powder, or colorless liquid. Odorless.

  1. Naphthalene acetic acid used in organic synthesis, as a plant growth regulator, and as a raw material for nose and eye cleansing and eye clearing in medicine.
  2. Naphthalene acetic acid used as plant growth hormone, also used in organic synthesis.
  3. Broad-spectrum plant growth regulator. It can promote cell division and expansion, induce the formation of adventitious roots, increase fruit setting, prevent fruit dropping, and change the ratio of female to male flowers. Naphthalene acetic acid can enter the plant body through the tender cuticles of leaves, branches and seeds, and be transported to the affected parts along with the nutrient flow. It is usually used in wheat, rice, cotton, tea, mulberry, tomato, apple, melon, potato, forest, etc. It is a good plant growth stimulator. If it is used to prevent fruit falling, the concentration should not be too high, otherwise it will cause the opposite effect, because high concentration of naphthalene acetic acid can promote the production of ethylene in plants; when used to promote roots, it should be combined with indole acetic acid or other root-promoting effects The mixed use of medicaments, because naphthalene acetic acid is used alone, although the crop root-promoting effect is good, the seedling growth is not ideal. When spraying melons and fruits, it is advisable to spray evenly on the leaves. Generally, the spraying amount is about 7.5kg/100m2 for field crops and 11.3-19kg/100m2 for fruit trees. Treatment concentration: 10-30mg/L spray for melons and fruits, 20mg/L for wheat soaking for 6-12h, and 10-20mg/L for cotton 2-3 times in full bloom. This product can be mixed with general insecticides, fungicides and chemical fertilizers, and the effect is better if it is sunny and rainless.
  4. Naphthalene acetic acid is a plant growth regulator that promotes the growth of plant roots, and it is also an intermediate of naphthalene acetamide.
  5. Naphthalene acetic acid is used in organic synthesis, as a plant growth regulator, and as a raw material for nose and eye cleansing and eye clearing in medicine.
    It belongs to a broad-spectrum plant growth regulator for plant growth hormone. Organic Synthesis. Herbicide use A plant growth regulator with auxin activity.
  6. Naphthalene acetic acid is a naphthalene plant growth regulator with auxin activity, which is absorbed by roots, stems and leaves. NAA is widely used in agriculture, forestry, vegetables, flowers, fruit trees and other fields to induce adventitious root formation, increase the survival rate of tree cuttings, increase fruit setting rate, and prevent fruit drop before harvest.
Storage condition: Cool Dry Place
Long term storage: The warehouse is ventilated, low temperature and dry; it is stored and transported separately from the food raw materials.
