| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| toxicity | Acute oral LD50>825~1470mg/kg in rats, acute percutaneous LD50>4000mg/kg in rats, rats with acute inhalation of LC50>7.4mg/L (4H). Rats fed 2 years test dose of 3.6mg/kg per day. Trout LC50100 ~ 220mg/L (96H). The oral LD50 of quails was 250 ~ 500mg/kg. Safe for bees. |
| Use | phenoxypropionic acid herbicide, which belongs to hormone-type systemic herbicide. It has special effects on Polygonum palmatum and Polygonum Chunyu, and it is effective for the pig, and it is not effective for the pig. The recommended dosage for cereal crops is 1.2~1.5kg/hm2. Jing 2,4-drop propionic acid is an aryloxyalkyl acid herbicide, which is a hormone-type inhalation herbicide and is particularly effective for the spring and the horse. It can also be used to prevent the pig from suffering and breeding, but it has a certain effect on the flat storage. In cereal crops alone, the dosage of 1.2~1.5 (a. I.)/ha, or in combination with other herbicides. Can also be used at lower doses to prevent Apple fruit loss. |
| production method | methyl L-2-chloropropanoate ([α]20D-25.2 o) and methanol, 33% aqueous sodium hydroxide solution is mixed below 40 ℃, added to the mixture of 2, 4-dichlorophenol, sodium hydroxide and water at 90 ℃, heated at 90 ℃ for 1H, 4-drop propionate sodium salt. D-isomer> 87%. High 2,4-drop propionic acid can produce various esters. dichlorprop-p-isobutyl the molecular formula is C13H16Cl2O3;dichlorprop-p-dimethylammonium the molecular formula is c11h15cshi NO3,C.A.NO. [104786-87-0]. |
