CAS NO.: 51218-45-2
Common name: Metolachlor
Chemical name: 2-chloro-6-ethyl-N-(2-methoxy-1-methylethyl)acetyl-o-anilide
Chemical Structure:
Molecular formula: C15H22CINO2
Molecular weight: 283.8
Physicochemical properties: The original drug is a brown liquid with a boiling point of 100°C (0.133 Pa). The vapor pressure is 1.73mpa at 20°C, and the solubility in water is 530mg/L at 20°C. The solvent content is between benzene and other organic solvents. Dole is not volatile photolysis, leaching is small, stable in nature. 72% Dole EC is a yellow-brown liquid with a density of 1.04 to 1.06 at 20°C. It can be emulsified into emulsion in water. The preparation is flammable with a flash point of 24 to 42°C (closed). Can be mixed with a variety of herbicides. Product storage is stable within two years.
Usage: In corn, soybeans, peanuts, cotton and other crop fields, before spraying the crop with 72% EC 150-20 ml / mu, spray 40-50 kg of water.
In transplanting cotton, tomato, pepper, rapeseed, cucumber, watermelon, eggplant, tobacco field, etc., it is appropriate to apply the medicine 3-5 days before transplanting. With 72% EC 150-200 ml/mu, spraying 40-50 kg of water.
Note: The drug is easily degraded by soil microorganisms and gradually disappears after 70 days. Using metolachlor for soil treatment, its control effect is greatly affected by soil moisture. After repeated tests and field use, it has been proved that the soil has high humidity, which is beneficial to the absorption of pesticides, and the effect of weeding is better. When the soil moisture is small, the effect is reduced.
Toxicity data: Acute oral toxicity LD50 of metolachlor to the female and male rats was 2330 mg/kg and 3160 mg/kg, respectively, and acute dermal toxicity LD50 was greater than 2150 mg/kg.
Packing specification: 200 kg/barrel, or according to customer requirements.
Quality index: Metolachlor content ≥ 95%, moisture ≤ 0.4%, acidity ≤ 0.1%
