NAA-Na prevents flowers and fruits from falling and has an anti-fall function. In addition, it can also promote flowering and fruiting, promote luxuriant branches and leaves, increase yield, improve quality, and improve the crop's resistance to drought, cold, lodging and other stresses.

1-Sodium naphthaleneacetate: The original drug is white powder (free acid), soluble in water and oil, without precipitation and floating oil;

The melting point is 120℃, and it is stable at room temperature.

Toxicity LD50 (mg/kg): about 1000 for acute oral administration in rats and about 700 for mice (sodium salt); slightly irritating to the skin and mucous membranes. Use according to the prescribed dosage, it is non-toxic to bees. People should avoid inhaling drug mist and avoid contact between the drug solution and the skin and eyes; do not pour the residual drug solution into rivers, ponds, etc. to avoid polluting the water source. There is no specific antidote. If symptoms of poisoning occur, go to the hospital immediately.

Sodium naphthaleneacetate and naphthaleneacetic acid strong base weak acid sodium salt, after hydrolysis, produce naphthaleneacetic acid. Plants use ions, so as long as there are naphthaleneacetic acid ions, it can work. Naphthaleneacetic acid is a broad-spectrum plant growth regulator that can promote cell division, induce the formation of adventitious roots, change the ratio of male and female flowers, increase fruit setting rate, etc. Naphthaleneacetic acid is mainly through plant leaves. The epidermis of young branches enters the plant body and is transported to the active part along with the nutrient solution.

1. For soaking sweet potato seedlings, the method is to soak the base of the bundled potato seedlings 3cm in the liquid, the soaking concentration is 10~20mg/kg, and the time is 6 hours;

2. When transplanting rice, soak the roots of the seedlings, the concentration is 10mg/kg for 1~2 hours; for wheat, the concentration is 20mg/kg, and the time is 6~12 hours;

3. For cotton, it is used for leaf spraying during the flowering period, the concentration is 10~20mg/kg, and a total of 2~3 sprays during the growth period. If used to prevent fruit drop, the concentration should not be too high, otherwise it will cause the opposite effect, because high concentration of naphthaleneacetic acid can promote the production of ethylene in plants;

4. When used for root promotion, it is advisable to mix with indoleacetic acid or other root-promoting agents, because naphthaleneacetic acid alone has a good root-promoting effect on crops, but the seedling growth is not ideal. When spraying melons and fruits, it is advisable to spray the leaves evenly. The general spraying amount for field crops is about 7.5kg/100m², and for fruit trees it is 11.3-19kg/100m². Treatment concentration: 10-30mg/L spray for melons and fruits, 20mg/L soaking for 6-12h for wheat, and 10-20mg/L spray 2-3 times during the flowering period for cotton. This product can be mixed with general insecticides, fungicides and fertilizers, and the effect is better when the weather is clear and there is no rain.

100g/bag, 250g/bag, 500g/bag, 1000g/bag, 10kg/box or 25kg/barrel, provide packaging according to your needs.

1. Solubility: Because it exists as a single molecule in the solution, it is evenly dispersed and easily absorbed by plants, while ordinary sodium α-naphthylacetate with a content of 80% needs to be dissolved in ethanol, etc., which is very inconvenient to use. It exists in the form of molecular clusters in emulsifiable concentrate powders, with poor dispersibility and naturally poor effects.

2. High purity, no impurities, no toxic side effects: The purity of any plant growth regulator and pesticide is related to its effect. For example, high-purity α-naphthylacetic acid sodium 5ppm (5μg/g) has a very good effect, while ordinary α-naphthylacetic acid sodium needs to reach 20ppm (20μg/g) to be effective.

3. Good compatibility: High-purity α-naphthylacetic acid sodium can be used in combination with auxin, sodium nitrophenolate, rooting substances, fungicides, fertilizers, etc.
