Use  For the prevention and control of rice pests, Rice Chilo suppressalis, Chilo suppressalis, rice leaf roller, Rice thrips have a good control effect

Preparation

Dimethylamine and liquid alkali were added dropwise to allyl chloride, and the reaction was heated to obtain N,N-dimethyl propylamine, which was acidified with hydrogen chloride and chlorinated with chlorine gas, 1-= methylamino -2,3-= chloropropane was obtained. By adding the chloride and liquid alkali prepared as described above to sodium thiosulfate, an aqueous insecticidal double solution can be obtained.

Use

Silkworm poison pesticide, is a biological insecticide. It is effective for lepidopteran pests, with strong killing, stomach poison, internal absorption and egg killing effect. By blocking the nerve conduction of the pest, the worm gradually softens and paralyzes to death. Insecticidal double on rice, wheat, corn, beans, vegetables, citrus, fruit trees, tea, forest and other crops of the main pests have excellent control effect, mainly used for the control of rice borer, rice longitudinally rolled leaf cicada, Rice thrips, negative mud insects, etc., can also be used to control citrus leaf moth, corn borer, aphids, cotton red spider, cabbage, etc., sericulture area is best to use granules, anhydrous paddy field particles should not be used.

Safety

The oral LD50 of male rats was 200 mg/kg, the oral LD50 of mice was -235mg/kg, and the percutaneous LD50 of mice was 2026mg/kg. Less toxic to bees and natural enemies of pests. It is toxic to silkworm.
