1-Naphthaleneacetic acid is a plant growth regulator that promotes plant root growth. 1-Naphthaleneacetic acid promotes cell division and expansion, induces the formation of adventitious roots, increases fruit setting, prevents fruit drop.1-Naphthaleneacetic acid can enter the plant through the tender epidermis and seeds of leaves and branches, and is transported to the action site along with the nutrient flow. It is commonly used in wheat, rice, cotton, tea, mulberry, tomato, apple, melon, potato, forest, etc. It is a good plant growth stimulating hormone.
Recommended dosage on different crops
1.Wheat, rice: Soaking them with naphthalene acetic acid solution 20-40mg/L for (6-12 hours) or spraying them during growth period. It can promote growth, early maturity and increase yield.
2.Cotton: Spraying the leaves with 10-20mg/L naphthalene acetic acid solution during the flowering period of cotton. It can increase the yield of cotton.
3. Watermelon: Spraying it with 30-50mg/L naphthalene acetic acid solution at the flowering stage of watermelon, spray once every 7-10d, spray a total of 4-5 times, which can promote the growth of watermelon fruit.
4.Pear tree: Spraying it with 40mg/L solution in the flowering period of pear trees. It can save labor and have good effect for fruit thinning.
5.Melon: Spraying flowers with 200-300mg/L naphthalene acetic acid solution during the flowering period . It can increase the fruit setting rate of melon.
1. Naphthaleneacetic acid is hardly soluble in cold water. When preparing, it can be dissolved in alcohol first, then diluted with water
2. Although it has a good effect on rooting of cuttings, it has the side effect of inhibiting the growth of stems and branches on the ground at higher concentrations, so it should be mixed with other rooting agents.
3, When it be used as foliar spray, different crops or the same crop at different times, the use of different concentrations, It must be strictly in accordance with the instructions for use, do not arbitrarily increase the use of concentration.
