Product Description


Sodium a-naphthaleneacitic acid is a auxin class broad-spectrum type of plant growth regulator, it can enter plant body through plant leaf and tender skin to arrive vigorous growth parts together with nutrition of conducting. Sodium a-naphthaleneacitic acid can promote root differentiation and form, speed up branches and transplanting nursery stock cutting root growth, induce flower open, accelerate chlorophyll synthesis,prevent flower and fruit-dropping, prevent become seedless fruits, promote earlier ripe and increase yield well. Meanwhile Sodium a-naphthaleneacitic acid can increase the ability of resist-dry, resist-cold, resist-disease, resist-Alkali.


1.Make into formulation in single

(1)Sodium a-naphthaleneacitic acid can made into water formulation, oil formulation, powder formulation. It can promote growth, root growth, keep flower and fruits, use in crops widely. Reference application dosage in following form.

(2)Sodium a-naphthaleneacitic acid use in soil: Sodium a-naphthaleneacitic acid can use in blunt, drip and irrigation, use 8-10g/667square meters, promote root developed, promote overground part stronger, increase ability of resist-disease and natural calamities to get harvest.

2. Mixture use

(1)Sodium a-naphthaleneacitic acid can used mix with auxin, this is called root stimulate. Normal root growth formulation: Sodium a-naphthaleneacitic acid mix with Potassium IBA scientifically, widely used in tissue culture, Rooting cuttings and low temperature promote root mention seedling,increase resist-ability. This mixture mainly effect of sodium a-naphthaleneacitic acid to promote fibrous root growth and differentiation generation. Make root developed, increase the absorptivity of water, N、P、Kand other nutrient element, increase the use ratio of fertilizer.

(2) Sodium a-naphthaleneacitic acid mix with sodium nitrophenolate produce into Nitro phenol and Naphthylacetic preparation, such as 2.85% Kuaifengshou to regulate plant growth. This have application over 20year in Japan, Taiwan. They can increase efficiency reciprocally to get yield twice the result with half the effort. They also used in soil application.

(3) Sodium a-naphthaleneacitic acid mix with other plant growth regulator: Sodium a-naphthaleneacitic acid together with Choline Chloride, usually used in sweet potato, cassava, potato, onion ginger, garlic, radish and other root tuber crops. Through light respiration can increase photosynthetic efficiency, promote the transportation of organic matter. Transport photosynthate into root tuber crops to increase yield highly. Sodium a-naphthaleneacitic acid mix with ethephon,mainly used in flower of lichee to increase yield.

(4)Sodium a-naphthaleneacitic acid mix with foliar fertilizer, wash fertilizer to increase fertilizer utilization ratio, promote root growth, keep flower and fruit. Ratio with foliar fertilizer is 2-10ppm spray on stem and leaf to promote growth. Mix with compound fertilizer and wash fertilizer can enhance root, if add sodium nitrophenolate, effect is best.

(5)Sodium a-naphthaleneacitic acid mix with fungicides: Mixture of Sodium a-naphthaleneacitic acid and methyl have good effect in control rot of apple.This can prevent pathogenic violations and increase fungicide efficiency highly.

(1)When sodium a-naphthaleneacitic acid under ionic condition, don't mix with strong acidity pesticides and fertilizer.

(2)When application, must take care some sensitive crops, such as melon, peach, apricot, plum, jujube, grape, strawberry, better do some test before use.
