Toxicity | LD50 in rats, mice, Japanese quail, rabbits (mg/kg): 5800, 3700, 4997, 2680 orally; LD50 i.p. in rats: 550 mg/kg (Williams) |
EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
toxicity | acute oral LD50 in rats is 5800mg/kg, while that in mice is 3700mg/kg. The acute percutaneous LD50 was 3200mg/kg in mice and more than 2000mg/kg in rabbits. Rats were fed with 5000mg/kg diet for 3 months without adverse effects. No teratogenic, carcinogenic and mutagenic phenomena were found under the experimental conditions. No irritation to the skin. The LC50 for rainbow trout was 428mg/L (96h). |
use | it is suitable for preventing and controlling diseases caused by uniaxial mold and frost mold on fruit trees, vegetables, flowers and cash crops systemic fungicides, with upper and lower bidirectional conduction. It is effective for many diseases of the genus Phytophthora, Phytophthora, and uniaxial frost, and has a long duration. Mainly used for cucumber, vegetables, lettuce, grape downy mildew, with 40% wettable powder 400~600 times liquid spray, once a week, a total of 3~4 times. In addition, it is also used for tomato, potato, eggplant cotton blight, watermelon brown rot, citrus root rot, stem ulceration, pineapple heart rot, rice ear neck blast and striated orange disease, etc., and also has good effects. High-efficiency, low-toxicity, broad-spectrum systemic organic phosphine fungicides are used to prevent and control diseases of vegetables, fruit trees, flowers, and cash crops. |
Production method | Diethylphosphite is reacted with ammonia to prepare ammonium salt, and then aluminum sulfate is metathesis to obtain ethylphosphorous aluminum. The purity of the obtained original drug can reach above 90%. Raw material consumption quota: 1150kg/t diethylphosphite, 940kg/t concentrated ammonia water and 998kg/t solid aluminum sulfate. Phosphorus trichloride and ethanol remove hydrogen chloride in the presence of a small amount of water to generate diethylphosphite and a small amount of monoethylphospheneate; under the action of a slight excess of ammonia or sodium hydroxide, it generates monoethylphosphonic ammonium (or sodium); then reacts with a slight excess of aluminum sulfate to produce aluminum triethylphosphonate. |
