NAA can prevent fruits and vegetables from falling flowers, change female and male flowers ratio, reduce cotton ball falling, increasing fruit weight gain, improve quality.
NAA is a broad-spectrum-based plant growth regulator, it can promote cell division and expansion, induce the formation of adventitious roots, scope for cereal crops, increase tillers, panicle rate and grain weight; promote flowering fruit trees, anti-fruit drop, ripening increase.

a. Increase fruit-setting ratio:
1. Orange, apple, pear etc: to spray whole trees by 15-20mg/L in young fruit period; within 45days before picking, to spray the trees by10-20mg/L NAA liquid. Every 10-15days, it can accelerate fruit growth, prevent fruit from falling, and increase output obviously;
2. Watermelon, to spray the flowers in the earlier bloom period by 20-30mg/L NAA liquid, it can increase fruit-setting ratio, increase output;
b. Promote fruit and tuber enlarge quickly:
1. Sweet potato: to dip the young branch before transplant by 10-20mg/L for 6 hours, it can increase the activity ratio, enlarge the sweet potato, increase the output;
2. Cabbage, radish: Before sowing, to soak the seeds by 15-30mg/L for 12 hours, and then wash the seeds one or two times and then dry in the sun. It can accelerate fruit enlarge, and increase output about 15-20%;
3. Cotton: to spray the plants by 15-20mg/L NAA since blooming period, spray once in every 10~15days, total spray 3 times, it can prevent cotton-ball from falling, enlarge cotton boll, and increase output.
c. To promote plant grow quickly and stronger, increase output and improve quality:
1. Corn: Soak the seed by 20-30mg/L for 12 hours before seeding; To spray the plants by 15-20mg/L in growing period, it can accelerate growing, increase output.
2. Wheat, rice: Soak the seed before seeding by 10-20mg/L liquid; to spray the plants by 15-25mg/l NAA liquid before shooting period, it can make plant stronger; To spray by 20-30mg/l NAA liquid in tillering stage. It can increase fruit-setting ratio, increase weight, increase wheat quantity, and it can enhance wheat resistibility on dry-hot wind, chilliness, disease etc.
3. Tomato, eggplant, cucumber etc: To spray the plants by 5-20mg/L NAA liquid 1-2 times in growing period, it can promote growth , enlarge fruit and increase output about 10%-20%;
4. Beans: to soak the seed by 10-20mg/l NAA liquid before seeding, and to spray the plant by 5-20mg/L NAA liquid, it can accelerate growth, let beans ripe earlier, increase output.
d. To promote formation of adventitious root and root
NAA is not soluble in water, we also has its sodium salt: sodium-NAA, it has the same effect with NAA and it is soluble in water.
