1. Functional characteristics of a-Naphthylacetate 1. High-purity sodium a-naphthylacetate has a purity of more than 98% and contains no other organic impurities. It will not cause any harm to crops within its effective use concentration range, but ordinary a- Naphthylacetate contains 20% of organic impurities, and it will poison the young leaves, young shoots, and seedlings of young plants within the effective concentration range. The high-purity sodium a-naphthylacetate 5ppm (5μg/g) has a good effect, while the common sodium a-naphthylacetate needs to reach 20ppm (20μg/g) to have an effect. 2. High-purity sodium a-naphthylacetate has two water-soluble and oil-soluble properties, so it can be separately formulated into liquid formulations, powders, emulsifiable concentrates, granules, etc., and it is very convenient to use. The effect is very good. Because it is a single molecule in the solution, it is evenly distributed, which is good for plant absorption. However, 80% of the common content is only soluble in oil and it is inconvenient to use. Dilution with ethanol is required, and it is present in the form of micelles in the emulsion powder. It has poor dispersibility and is not easily absorbed by plants. The effect is naturally poor. 3. High-purity sodium a-naphthylacetate can be used in combination with many plant growth regulators, such as auxin, sodium nitrophenolate, fungicides, fertilizers, etc.; and normal sodium α-naphthylacetate has not been compounded so far. preparation. 2. Application Technology of a-Naphthyl Acetate 1. Separate use of high-purity sodium a-naphthylacetate can be formulated separately into water, powder, emulsifiable concentrate and other dosage forms, with various effects of high-purity sodium a-naphthylacetate. Rooting sprouting, keeping flowers and other fruits. 2. For compounding use (1), high-purity sodium a-naphthylacetate can be compounded with auxin compounds, such as compounding with auxin into rooting powder and other dosage forms. (2) It is used together with compound sodium nitrophenolate to protect flowers and fruits, such as 2.85% of nitronaphthalene water, which is a good regulator on the market. (3) Compounding with fungicides can prevent viruses and other diseases. (4) Compounding with fertilizer can increase fertilizer utilization and promote plant root absorption.
