Dora Agri-Tech is one of the biggest 1-Naphthylacetic Acid suppliers, we exported to South America and Western Europe for many years about 30mt per year. Due to the stable quality and competitive price.  1-Naphthylacetic acid is a broad-spectrum auxin plant growth hormones, which can enter the plant body through plant leaves and reach vigorous growth parts together with the nutritions conduction. NAA can promote root differentiation and formation, accelerate roots transplantings and cuttings, induce flowering, accelerate chlorophyll synthesis, reduce fruit dropping, promote crop maturity and increase crop yields. Specification of NAA Physical & Chemical Features CAS No.: 86–87–3 Appearance: White crystal Purity: 98%Min (HPLC) Common Name: 1-Naphthylacetic Acid Chemical Name: 1-Naphthaleneacetic Acid, a-Naphthaleneacetic Acid, Alpha-Naphthyl Acetic Acid, NAA Molecular Formula: C12H10O2 Molecular Weight: 186.21 pH: 3.0–5.0 Application of NAA 1. Prevent From Abscission Of Flowers And Pods On Bean; Prevent Flower Dropping On Capsicum 1) As for Bean, during the flower and pod stage, use 5~25 mg/kg NAA solution for spray, which can effectively reduce the abscission of flowers and pods. 2) As for Capsicum, during the flowering stage, use 50 mg/kg, spray 4~5 times every 7~10 days, which can obviously increase fruit set, promote fruit growth. 2. Prevent From Radish Become Hollow 25~30 days and 35~40 days after radish seeding, spray 10 mg/kg NAA, which can prevent hollowing during growth; spray 10 days before harvest, which can prevent hollowing during storage. 3. Contribute To Cutting Reproduction On Vegetables 1) Cut the lateral bine from the cucumber that grown in the open air, 2~3 joints every section, a quick soak in the 500 dilution solution, it will form root after sticking 11 days, the survival rate can reach 85%. 2) Cut the keel with one axillary bud of leaf base on cabbage and cauliflower, a quick soak in 500~1000 dilution solution (Do not soak the bud), sticking under the condition: Temperature(20?~25?), Humidity(85%~95%), the rooting survival rate can reach 85~95%.
