Overview | bifenthrin is one of the new varieties of pyrethroid insecticides developed rapidly from 70 to 80, which is widely used in the world. Bifenthrin moderate toxicity to humans and livestock, the drug has a high affinity in the soil, insecticidal activity is very high, the insect stomach poison, contact killing effect, used in a variety of crops to control aphids, mites, cotton bollworm, pink bollworm, peach caryolysin, leaf hopper and other pests. |
toxicity | Acute oral LD50 was 54.5mg/L in rats and acute percutaneous LD50>2000mg/kg in rabbits, the skin and eyes of rats and rabbits were not stimulated, and the skin of guinea pigs was not sensitized. Animals were fed two trials with no effect concentration of 50mg/kg. No carcinogenic, teratogenic or mutagenic effect was found in animal test, and no abnormality was found in the third generation reproductive test. It is highly toxic to fish, with LC50 of 0.35 μg/L (96H), l500.15 μg/L (96h) for rainbow trout and l500.16 μg/L (48h) for Daphnia. Wild duck acute oral LC50 concentration of 1280mg/kg feed (8d), quail LC504450mg/kg feed (8d). |
Use | pyrethroid insecticides and acaricides. With a knock-down effect of strong, broad-spectrum, efficient, fast, long residual effect in the characteristics, to kill the role of contact and stomach toxicity, no absorption effect. Can be used for the control of cotton bollworm, pink bollworm, tea geometrid, tea worms, Apple or Hawthorn Red Spider, peach Carina, vegetable aphid, cabbage, vegetable moth, citrus leaf moth. Such as the prevention and control of cotton bollworm, pink bollworm in the second and third generation of egg incubation period, young insects into the bud, before the Boll, or control of cotton Red Spider, in the formation, if the occurrence of mites, spray with 10% ~ 6mL/3.4 m 2 or 7.5~6mL/4.5 m 2 of water. And can also be treated cotton aphid, bridge worm, rolled leaf worm, thorn moth, thrips and so on. Control of tea geometrid, tea worms, tea moth, with 10% emulsifiable concentrate 4000~10000 times liquid spray. it can kill both insects and mites, and has a good control effect on cotton, vegetables, fruit trees, tea tree and other pests control cotton bollworm, cotton red spider, peach, pear, hawthorn spider mites, Citrus Red Spider, macular mists, tea wing mists, vegetable aphids, cabbage worms, diamondback moth, eggplant Red Spider, tea moth and other more than 20 kinds of pests, whitefly, tea geeerigeron, tea worms. |
production method | preparation method-2-phenylbenzoyl chloride is prepared by reacting 2-phenylbenzoic acid with socl2, the corresponding 2-phenyl benzamide is obtained by reaction with dimethylformamide, and 2-phenyl dimethyl benzylamine is obtained by reduction with lithium aluminum hydride. The corresponding ammonium salt was prepared by reacting 2-phenyldimethylbenzylamine with CH3I, and then reacted with ethyl chloroformate after isomerization to obtain 2-methyl-3-phenylchlorobenzyl chloride. Finally, Bifenthrin was prepared by refluxing the corresponding acid in acetonitrile for 16h in the presence of KOH. Preparation Method 2 is prepared from 3, 3-dimethyl-1-enopentanoic acid 2-methyl-3-phenylbromobenzyl by condensation, cyclization and dehydrochlorination. |
