A synethetic auxin used as a plant growth regulator to control top fruit pre-harvest fruit drop, for fruitlet thinning and for striking hard and softwood cuttings.
1. Promote fruit and tuber enlarge quickly:
To used on 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;
To used on 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%;
To used in 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.
2.To increase fruit-setting ratio:
To used on 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;
To used on watermelon, to spray the flowers in the earlier bloom period by 20-30mg/L NAA liquid, it can increase fruit-setting ratio, increase output;
3.To promote formation of adventitious root and root:
4.To promote plant grow quickly and stronger, increase output and improve quality:
To used on 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.
To used in 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.
To used on 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%;
To used on 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.
