Physical and chemical properties:

Off-white powder, soluble in hot water, acetone, ethanol and caustic soda, slightly soluble in water.

Functions:

Naphthalene acetic acid naphthalene Plant growth regulator with Auxin activity, absorbed by roots, stems and leaves Naphthalene acetic acid is widely used in agriculture, forestry, vegetables, flowers, fruit trees and other fields to induce adventitious root formation, improve the survival rate of tree cuttings; Fruit rate, to prevent pre-harvest fruit drop.
1, it stimulates cell division and tissue differentiation, promote ovary enlargement, induce parthenocarpy, promote flowering.
2, in a certain range can inhibit cellulase, to prevent falling fruit.
3, low concentration can promote the growth and development of plants, high concentrations can produce dwarf and ripening increase the role.

Method of use:

1, naphthalene acetic acid and indole butyric acid can be used as rooting agent to promote rooting of watermelon, which can increase rooting rate of sugarcane.
2, naphthalene acetic acid and calcium chloride mixture can prevent tomato disease.
3, Naphthylacetic acid and sodium nitrophenolate complex use, (1.2% naphthalene acetic acid +1.65 sodium nitrophenolate sodium.) In wheat, rice heading stage to the use of grain filling, can increase production; peanut, soybean podding period Use, can have a significant role in production.
4, Naphthylacetic acid and compound vitamins combined use, the magnolia plant rooting has obvious synergistic effect.

Cautions:

1, although the rooting on the effect of good, but at a higher concentration of inhibition of the ground stem and branch growth side effects, so with other rooting agent compound used better.
2, for foliar spray, different crops or the same crop at different times in different concentrations, do not arbitrarily increase the concentration, in order to avoid phytotoxicity.
3, used as a fruit agent, pay attention to the flower as much as possible to spray the whole plant to promote fruit set, to a small number of times, and with the foliage Fertilizer with better.
