| Use | Foukewei is also known as Caomiping, benzoic acid is a selective preseedling herbicide, and its chemical name is 2, 5-dichloro-3-aminobenzoic acid. Doukewei mainly inhibits the absorption of oxygen by mitochondria in cells, thereby killing weeds; crops such as soybeans have strong resistance and can be metabolized and lose their activity. It can be used for weeding before selecting buds in soybean fields, and can also be used for weeding in wheat, corn, tomatoes and vegetable fields. The main objects of action are annual weeds such as barnyard grass, Matang, Kanmai Niang, Setaria and so on. The medicine is less harmful and is not affected by the weather. |
| biological activity | Chloramben (3-Amino-2,5-dichlorobenzoic acid) is a pre-emergence herbicide used to inhibit the growth of seedlings of annual grasses and broadleaf weeds. |
| production method | is obtained by chloromethylation of paraformaldehyde, oxidation of potassium permanganate, nitration of nitric acid and reduction of tin particles. |
| category | pesticide |
| toxicity classification | poisoning |
| acute toxicity | oral-rat LD50: 3500 mg/kg; Oral-mouse LD50: 3725 mg/kg |
| flammability hazard characteristics | Combustion produces toxic nitrogen oxides and chloride gases |
| storage and transportation characteristics | warehouse ventilation and low temperature drying; separate from food raw materials storage and transportation |
| fire extinguishing agent | dry powder, foam, sand |
