CAS No.: 86-87-3

Molecular formula: C12H10O2

Brand Name: Colorcom

Shelf Life: 2 Years

Place of Origin: China

Product Specification:

Product Description:
Naphthaleneacetic acid can promote plant growth, rooting of cuttings, thinning flowers and fruits, prevent flower and fruit drop, promote flowering, inhibit budding, promote early maturity and increase production.

Application: 

1. Promote the formation of adventitious roots and roots

(1) Grapes. Before cutting, dip the branches with 100-200mg/L solution to promote rooting, rapid germination, and strong plant development.

(2) Tree transplanting. Dip the roots with 100-200mg/L solution before transplanting to promote rooting and increase survival rate. For tea, mulberry, oak, metasequoia, etc., dip the base of the cuttings with 10-15mg/L solution for 24 hours to promote rooting.

2. Promote the rapid expansion of fruits and tubers

(1) Sweet potatoes. Bundle the potato vines and soak the sweet potatoes. The method is to soak the base of the bundled potato vines 3cm in the solution, with a concentration of 10~20mg/kg, and transplant the seedlings after 6 hours; or use 80~100mg/L solution to dip the seedlings 1 inch for 3s and transplant them immediately; this can improve the survival rate, expand the tubers, and increase the yield.

(2) Radish and cabbage. Soak the seeds in 15~30mg/L solution for 12h, remove and rinse with clean water 1~2 times, and sow after drying. This can promote fruit expansion and increase yield.

3. Improve fruit setting rate, preserve flowers and fruits, and prevent fruit drop

(1) Citrus. Spray the fruit stalk with 40~60mg/L solution 15d before harvesting to prevent fruit drop before harvesting and increase yield.

(2) Apple, pear, and red date. During the young fruit stage, spray the whole plant with 15-20 mg/L solution, starting 45 days before harvest, spray once every 15 days, and spray the whole plant 2-3 times to promote growth, prevent fruit drop before harvest, and increase yield.

(3) Watermelon. When the female flowers first bloom, soak or spray the flowers with 20-30 mg/L solution to increase the fruit setting rate.

(4) Cotton. Spray the leaves of cotton at the beginning of the flowering period, with a concentration of 10-20 mg/kg, at intervals of 10-15 days, and spray 2-3 times during the growth period to prevent buds and bolls from falling off.

The concentration should not be too high, otherwise it will cause the opposite effect, because high concentrations of naphthaleneacetic acid can promote the production of ethylene in plants;

(5) Pepper. Spray the whole plant with 20 mg/L during the flowering period to prevent flower drop and promote pepper setting.

4. Promote growth, strengthen plants, increase yield, and improve quality

(1) Wheat. Soak the seeds in 10-20 mg/L solution for 6-12 hours, remove and rinse with clean water 1-2 times, and sow after drying; spray 15-25 mg/L solution before jointing; spray 20-30 mg/L solution on the flag leaf and panicle during the tillering period to promote tillering and increase the panicle rate. After application, the salt-alkali resistance can be improved, the yield can be increased, the thousand-grain weight can be increased, the number of panicles can be increased, the dry hot wind resistance can be increased, and the yield can be increased.

(2) Rice. When transplanting rice, soak the roots of the rice seedlings at a concentration of 10 mg/kg for 1-2 hours; soak the seeds of wheat at a concentration of 20 mg/kg for 6-12 hours before transplanting; spray the flag leaf and panicle with 20-30 mg/L solution to promote greening, make the plants strong, and increase yield. Use a concentration of 3-10 mg/L in the rice seedling field and spray on the leaves to regulate the growth of rice.

(3) Corn and millet. Soak the seeds in 20-30 mg/L solution for 12 hours, remove and rinse with clean water 1-2 times, and sow after drying; spray the leaves with 15-20 mg/L solution during the growth period to promote growth and increase yield.

(4) Cotton. Use 1-8 mg/L concentration for stem and leaf spray to regulate growth.

(5) Tomato and eggplant. Before planting and at the beginning of flowering, spray the leaves with 5-12 mg/L solution, spray once every 10-15 days, for a total of 3 times, to promote growth and increase yield.

(6) Cucumber. Spray the whole plant with 5-20 mg/L solution 1-2 times during the growth period to increase the density of female flowers and regulate growth.

(7) Beans. Soak the seeds in 10-20 mg/L solution for 0.5-1 hour before sowing; spray 5-20 mg/L solution 2-3 times during the growth period to promote growth, accelerate maturity, and increase yield.

(8) Potato. Soaking the tubers with 10-20 mg/L solution for 12-24 hours can promote growth.

(9) Pineapple. Spray leaf buds and flower buds with 10 mg/L solution before flowering. Spray young fruits with 20 mg/L solution 2-3 times when fruits are formed. In the late stage of vegetative growth, inject 30 mL of 15-20 mg/L solution from the center of the plant to promote growth and increase yield.

(10) Sugarcane. Spray the leaves with 15-20 mg/L solution 2-3 times during the tillering period to promote growth and increase yield.

(11) Apple. Use a concentration of 30-50 mg/L and spray the leaves 1-2 times to significantly increase yield.

(12) Lemon. Spraying the lemon crown with 0.1% solution can accelerate fruit ripening and increase yield.

(13) Tobacco. Spray the leaves with 10-20 mg/L solution 2-3 times during the growth period to regulate tobacco plant growth and improve tobacco leaf quality.
