α-Naphthalene Acetic Acid

Description: Broad-spectrum plant growth regulator. It can promote cell division and expansion, induce the formation of adventitious roots, increase fruit set, prevent fruit falling, and change the ratio of female and male flowers. Naphthalene acetic acid can enter the plant body through the tender epidermis of leaves, branches and seeds, and be transported to the site of action along with the nutrient flow. Usually used in wheat, rice, cotton, tea, mulberry, tomato, apple, melon, potato, forest, etc. , is a good plant growth stimulating hormone. If used to prevent fruit falling, the concentration should not be too high, otherwise it will cause the opposite effect, because the high concentration of naphthalene acetic acid can promote the production of ethylene in the plant body; When used for root promotion, it should be mixed with indole acetic acid or other agents that have the effect of root promotion. Because naphthyl acetic acid is used alone, the root promotion effect of crops is good, but the seedling growth is not ideal. When spraying fruits and melons, it is appropriate to spray evenly on the leaf surface. The amount of spray liquid is about 7. 5kg/100m2 for field crops and 11. 3 ~ 19kg/100m2 for fruit trees. Treatment concentration: melon and fruit 10-30mg /L spray, wheat was 20mg/L sowed for 6-12h, cotton was 10-20mg /L spray 2-3 times in full bloom.
