application | glyphosate is a plant growth regulator, which has remarkable effect on ripening and sugar enhancement, low toxicity and low residue, and can be used for growth regulation of sugarcane, sugar beet, sweet potato, fruit, soybean cotton and other crops. In addition, glycosylphosphine has a methylphosphonic acid structure, which conforms to the structure of phosphonic acid corrosion inhibitor, and can also be used as a metal corrosion inhibitor. Organic phosphonic acid corrosion inhibitors can chemically react with Ca2 ,Fe2, etc. in water or solution to form a layer of insoluble precipitate or complex, and continuously deposit on the metal surface to form a layer of dense protective film, The metal surface is separated from the corrosion environment to reduce the metal corrosion rate. |
ripening agent | Glyphosate is also called ripening phosphorus and glycymphos. The trade name is Polaris. Chemical name: N,N-bis (phosphonate methyl) glycine. A ripening agent. It can inhibit the activity of sugar cane acid invertase and inhibit sucrose hydrolysis, thus increasing sucrose accumulation. Spraying 4~8 weeks before harvest can delay the growth of sugarcane plants, become shorter, improve field ventilation and light transmission, and promote maturity. High concentrations of glyphosate also have the function of herbicides. |
mode of action | through plant foliar absorption, it has ripening and sugar-increasing effects on crops such as sugar cane and sugar beet. |
mechanism of action | glyphosate is a medicine that can stimulate plants to produce ethylene. It has a significant effect on the ripening and sugar content of sugarcane and sugar beet. In sugarcane, it has the effect of preventing the conversion of acid invertase to sucrose, thus accumulating sucrose and increasing the yield. In the case of high concentration, it has herbicide effect and is used as cotton defoliant. |
control objects and methods | foliar spraying can increase sugar content. Spraying 0.56kg/hm2 of sugar beet 30 days before harvest can increase sucrose yield by 10%. Can promote the growth and ripening of sugarcane. 2~6kg/hm2 was applied 9 weeks before sugarcane harvest, and the effect of increasing sucrose content was the best. Spray 0.56kg/hm2 of cotton during pod opening, and 70% ~ 80% of cotton can be defoliated within 7 days. Spraying 1500mg/L for apples and pears 9 weeks before harvest can increase the soluble solid content by 1% ~ 1.5%. |
precautions | (1) this product has weeding effect under high concentration, so the dosage of drugs should be strictly controlled when it is used as a production regulator to promote crop yield increase. (2) Low toxicity to animals, irritating to eyes and skin. General protection can be used during use and storage. When splashed on the skin and eyes, immediately rinse with plenty of water. (3) No special antidote, such as accidental poisoning, take symptomatic treatment. |
analysis method | potentiometric titration was carried out with 0.1N sodium hydroxide standard solution. The first jump point is about pH4 and the second jump point is about pH9. The difference between the two standard solutions is glycine content. The product content can be obtained by deducting glycine alkali consumption from the first sudden jump point. |
allowable residue | the allowable residue in sugarcane is 3 mg/kg. |
toxicity | acute oral LD503925mg/kg in rats and maximum lethal dose of percutaneous absorption in rabbits> 5010 mg/kg. It has strong irritation to the eyes and moderate irritation to the skin. Acute oral LD502825mg/kg of the original drug on mice. |
use | a foliar applied plant growth regulator, which can also be used as a defoliant before crop harvest. Mainly used for ripening and increasing grain of sugar cane and sugar beet. The United States was first introduced to the market as a sugarcane ripening agent in 1972. The best medication time is 9 weeks before sugarcane harvest, with a dosage of 24-45g of active ingredients/100 m2, which can make sugarcane mature 15-40 days earlier and increase sucrose yield by about 1%. If it is used for sugar beet 30 days before harvest, the dosage is 5.7g/100 m2, and the sugar is increased by 10%. It is used for defoliation of cotton and sprayed at the flocculation stage with 5.7g/100 m2 of medicine, and 75% ~ 99% of cotton leaves are defoliated within one week. Glycophos is a foliar application of plant growth regulator, can also be used as a defoliant before harvest. The main use is sugar cane and beet ripening and increasing sugar content. It was the first commercial sugarcane ripening agent in the United States and was put on the market in 1972. The best medication time is 9 weeks before sugarcane harvest, and the dosage is 2.4-4.5kg (active ingredient)/hm2. It can make sugarcane mature 15-40d in advance and increase sucrose by about 1%. It can be applied to sugar beet 30d before harvest, 38g per mu, which can increase sugar 10%. Used for cotton defoliation, 38g per mu is sprayed during the flocculent period, and 75-99% cotton leaves fall off within 7 days. Used as plant growth regulator |
Production method | It is prepared by reacting glycine with formaldehyde and phosphorus trichloride at 110 ℃. Raw material consumption quota: phosphorus trichloride 1400kg/t, glycine 1370kg/t, formaldehyde 1400kg/t. phosphorus trichloride method is prepared by reacting glycine with formaldehyde and phosphorus trichloride at 110 ℃. The phosphorous acid method is prepared by one-step condensation of glycine, formaldehyde and phosphorous acid in acidic medium. It can also be synthesized from phosphorous acid, a by-product in the production of palladium. The chloromethylphosphonic acid method is prepared by methylphosphonic acid of glycine and chloromethylphosphonic acid. |
