| toxicity | acute oral LD50 of rats is 40~50 mg/kg [original drug 22.7~160 mg/kg (male),22.7 mg/kg (female)]. Acute percutaneous LD50>500mg/kg in rats and 359mg/kg in rabbits. Inhaled LC50 in rats was 34.5mg/l (male, 4h) and 12.6mg/L (female, 4h). Mild irritation to skin and eyes without sensitization. The 13-week feeding test of rats had no effective dose of 10 mg/kg feed or 0.7 mg/kg body weight. The 2-year feeding test of rats had no effect on the dose of 15 mg/kg feed or 0.6~0.7 mg/kg body weight. The mutagenicity test was negative, and the second generation of rats had no adverse effects. No carcinogenic effect was found under the test conditions. No delayed neurotoxicity was found in the hen test. The joint meeting of FAO and WHO recommended ADI to be 0.006 mg/kg body weight (1989). The agent is highly toxic to fish, LC50 is about 0.002mg/L(96h), acute oral LD50 of wild ducks is 200~750 mg/kg, pheasant 620~1000 mg/kg, quail 85~106 mg/kg. The contact LD50 of bees is 7.1 μg/bee and the oral LD50 is 6.9 μg/bee. |
| use | organochlorine insecticides. It has the effects of contact killing and stomach toxicity, has a wide insecticidal spectrum and a long duration. When the temperature is higher than 20 ℃, it can also be used to kill insects. It can be used for cotton, fruit trees, soybeans, tea, vegetables, tobacco, potatoes and alfalfa and other crops. It has contact killing and stomach poisoning effects on insects. It can be used for the control of cotton bollworm, red bollworm, cotton leaf curling moth, diamond diamond, beetle, pear heart-eating worm, peach heart-eating worm, armyworm, thrips, leafhopper, aphids, cabbage, long beetle and other pests, with 20% EC 300~500 times spray. To control aphids and mites on cotton and fruit trees, spray 500~1000 times 20% emulsifiable concentrate. Root irrigation with 200 times of 20% emulsifiable concentrate can prevent and control cutworms. In recent years, endosulfan has achieved good results in the control of resistant cotton bollworm, especially when mixed with cypermethrin. Food or feed crops were stopped 3 weeks before harvest. |
| production method | endosulfan is heated and reacted with hexachlorocyclopentadiene and 1,4-butenediol for 10h, cooled, filtered and washed to prepare endosulfan, then heated endosulfan and solvent to a certain temperature, added sulfoxide chloride dropwise, dripped, maintained for 1h, dehydrochlorinated under reduced pressure, cooled, crystallized and filtered to prepare endosulfan. See References [3] for details. |
