| organophosphorus herbicide | glufosinate, also known as glufosinate, is a non-selective foliar-sprayed organophosphorus herbicide, it was first synthesized and developed by the Federal Republic of Germany Hoechst chemical company in 1976. The herbicidal action mechanism of Glufosinate is through the absorption of the leaves, with partial absorption, which can be transferred from the base of the leaves to the end, and less to other parts of the plant, no harm to undiscovered shoots and seeds. Ammonium metabolism in plants is disturbed in the short term after application, and strong cytotoxic ammonium ions accumulate in plants; The plants are poisoned and die. At the same time, photosynthesis was also severely inhibited, and the damaged plants were yellow and white after losing green, and began to die after 2~5 days. Loss of activity after contact with soil, only suitable for post-shoot spray. This information was edited by chemobook Yao Yao (2015-08-04). Application: Glufosinate is mainly used in orchards, nurseries, potato fields, nurseries, forests, ranches, ornamental shrubs, and non-cultivated field, to control annual and perennial Gramineae weeds, such as pinia, Wild Oats, malang, Humulus scandens, settail grass, Kentucky bluegrass, creeping grass, dog tooth root, shear, Reed, Festuca and so on. It can also control the broad-leaved weeds such as Chenopodium album, amaranth, Polygonum, chestnut, Solanum nigrum, purslane, pig, Sonchus, Thistle, Rosette, dandelion, etc, it also has a certain effect on the grass and the pteridophytes. When the Broad-leaved grass is sprayed on the weed population at a dose of 0.7-1.2/ha in the initial period of vigorous growth and the initial period of tillering of grass weeds, the control period is 4-6 weeks, if necessary, the drug can be administered again, which can significantly prolong the validity period. Potato field should be applied before Bud, It can also be sprayed before harvesting to kill the ground residues for harvesting. To control ferns, the dosage of 1.5~2kg per hectare. It is usually used alone, and sometimes it can be mixed with simazine, trichlorone or 2me4 chloride. FIG. 1 shows the chemical structural formula of glufosinate. |
| toxicity | Acute oral LD50 was 2000mg/kg in male rats and 1620mg/kg in female rats; male mice acute oral LD50431mg/kg, female mice were 416mg/kg; Dogs acute oral LD50200 ~ 400mg/kg. Acute percutaneous LD50>2000mg/kg in male rats and 4000mg/kg in female rats. No teratogenic, carcinogenic effect. Rainbow trout lc50320 mg/L (96H). |
| Use | organophosphate herbicide, glutamine synthesis inhibitor, non-selective contact herbicide. It has a certain role in the role of suction, can be used for the Orchard, yeast, non-cultivated land, can also be used for potato to control the annual or perennial dicotyledons and grass weeds and Cyperus, such as rat tail, horse, Tang, settail, wild wheat, wild corn, dactylit, Festuca arundinacea, curved grass, villous grass, ryegrass, Reed, Poa pratensis, wild oat, Brome, pig, baomai grass, wild sesame, solanum nigrum, flocks, creeping grass, shear, grass grass, field do not forget grass, dog tooth root, reverse branch amaranth, etc. The amount of use varies according to crops and weeds, and 1 ~ 2kg or more per hectare is used, such as the control of rubs and pteridophytes in forest and alpine pasture. The dosage was 1.5~20kg/hm2. It is used to control annual and perennial dicotyledonous and Gramineae weeds in orchards, nurseries, non-cultivated land, potato fields and so on, such as rat-tail damnique, Malang, bighead, wild barley, Lolium multiflorum, dog-tail grass, kenaf, wild wheat, wild corn, perennial grass weeds and Cyperus, such as: duck sprouts, curved grass, Festuca, and so on. |
| production method | O,O-diethyl methyl phosphonic acid is reacted with dibromoethane, brCH2CH2P (O)(OC2H5)CH3 was obtained by heating at 80 ℃ for 2H, and then (C2H5O2C)2CNa(NHCOCH3) was reacted at 85 ℃ to obtain (C2H5O2C)2C(NHCOCH3)CH2CH2P(O). (OC2H5)CH3 was refluxed with hydrochloric acid, and the resulting compound was reacted with 28% ammonium hydroxide at 60-70 ° C. For 8H to obtain glufosinate. In addition, glufosinate synthesis and high-pressure catalytic synthesis, low-temperature directional synthesis method, the use of the stroeckel reaction and micheresis plus, etc. See pesticides, Issue 9, 2002. |
