In recent years, fenvalerate is one of the main varieties of pyrethroid insecticides developed in the world. Its common name is Fenvalrate, its trade name is Sumicidin, code S-5602. Chemical structure: It is reported that the original drug at 23 ℃ for the yellow oily liquid, the proportion of 1.17 g / ml. Do not dissolve in water, soluble in xylene, acetone, methanol and other organic solvents. Stable in acidic solution, easy to decompose in alkaline solution. Heat resistance and light stability are better. The acute oral toxicity to rats, LD 50, was 310 mg / kg for males and 400 mg / kg for females. Dermal toxicity, male and female rats were greater than 5000 mg / kg. Subacute and chronic toxicity tests, found no pathological changes and mutagenesis, teratogenicity.
