Physical and chemical properties: The pure product is a colorless transparent oily liquid with a special odor. The original drug is a light yellow to brown oily liquid. Soluble in organic solvents such as propyl ether, ethanol, ether, chloroform, benzene, toluene, slightly soluble in water (3g / L, 16 ° C), insoluble in petroleum ether. 7. Toxicity: moderate toxicity 8. Category: Plant Growth Retardants 9. Main dosage form: 80%, 90% pyridinol emulsifiable concentrate 10. Functional characteristics: 80% pyridinol EC can inhibit the growth period of crops, promote root growth, make stems thick, thicken leaves, green leaves, enhance photosynthesis; control crop growth during crop reproductive period Promote reproductive growth, increase seed setting rate and increase 1000-grain weight; increase the number of nodules of legumes, increase nitrogen fixation capacity, reduce soybean pod formation, increase pod number and fruit number, promote early maturity and high yield; Certainly prevent disease and lodging resistance. 11. Using technology Soybean Vietnamese song 200mg / L concentration of pyridinol solution soaked for 2h, seed dressing with 80% pyridinol EC 4mL sprayed on 667m2 of soybean seeds, mix well, dry and sow. The leaf surface was sprayed once in the initial flowering stage and the full flowering stage, and 3 kg of 80% pyridinol emulsifiable concentrate per 667 m2 was added with water of 16 kg. Seed dressing +4 mL of 80% pyridinol emulsifiable concentrate and 667m2 of ground seed. Spray 4 mL of 80% pyridinyl emulsifiable concentrate and 15 kg of water between the initial flower and the full flower. This method has the best effect. Peanuts were soaked in 100 mg/L pyridinol solution (ie 90% pyridinyl emulsifiable concentrate 5.5 mL plus water 50 kg) for 4 h or 200 mg/L before peanuts were sown (ie 90 pyridine alcohol emulsifiable concentrate 11.1 mL plus water 50 kg). Soak seeds for 2 h, soak 40~50 kg of peanuts per 50 kg of liquid, and dry them after soaking. It can also be sprayed with a 500 mg/L concentration of pyridinol at the initial flowering stage or full bloom stage, ie, 667 m2 with 90% pyridinyl alcohol 27.8 mL plus water 50 kg. The sunflower was soaked in a 300 mg/L concentration of pyridin solution for 2 h before sowing, and then sown after drying to promote seedling growth and increase yield. 12. Notes (1) The concentration should be accurate and should not be too high to avoid excessive inhibition. Test before application to avoid loss. When dispensing pharmaceutical liquids and handling, avoid splashing liquid into your eyes or splashing on your skin. (2) The application of the field should strengthen the management of fertilizer and water to prevent water shortage, drought and lack of fertilizer and affect the normal growth of the plant. (3) This agent is highly toxic to fish, and should prevent the liquid from flowing into fish ponds and rivers when applying. (4) It should be kept in a safe place, and it is strictly forbidden to eat by humans and animals.
