τ-Fluvalinatesolution,100ppm - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| toxicity | the original drug has an acute oral LD50 of 260~280mg/kg, an acute percutaneous LD50>2000mg/kg and an acute inhalation LC50>5.1mg/l in rats. It has mild irritation to skin and eyes. Subacute oral no-effect dose is 3 mg/kg per day, chronic oral no-effect dose is 1 mg/kg per day. Animal experiments have not seen carcinogenic, teratogenic, mutagenic effects, and no effect on reproduction. Carp LC500.0048 mg/L (96h), trout 0.0029mg/L (96h), Daphnia 0.0074mg/L (48h). Wild duck LC50>5620mg/kg feed. It has a greater impact on silkworms and natural enemies. |
| use | high-efficiency, broad-spectrum pyrethroid insecticide, acaricide, stomach poison and contact killing effect, crop safety, long residual period. It can be used to control cotton bollworm, cotton red bollworm, cotton aphid, cotton red spider, corn borer, cabbage worm, diamondback moth, citrus leaf miner, tea caterpillar, tea inchworm, peach heartworm, green blind toon, leafhopper, whitefly, wheat armyworm, soybean heart worm, soybean aphid, beet armyworm, etc. For example, control cotton bollworm and red bollworm during the full incubation period of the eggs, before the young insects are eaten into the buds and bolls, control cotton aphid during the full growth period of wingless adult nymphs, and spray with 1000~2000 times of 20% emulsifiable concentrate; control rapeseed aphid and rapae Brassicae, with 20% emulsifiable concentrate 2.25~3.75mL/100 m2, spray 7.5g of water; control soybean heart feeding worms and wheat armyworm, spray with 3000~4000 times of 20% emulsifiable concentrate. Due to long-term continuous use, pests have developed drug resistance to the agent, and caused a variety of pyrethroids to produce cross resistance, for the already resistant pests should stop using it. Calibration instruments and devices; evaluation methods; working standards; quality assurance/quality control; others. |
| Production method | Preparation method-α-bromoisovaleric acid is chlorinated with SOCl2 to prepare α-bromoisovaloyl chloride, and then it reacts with α-cyano -3-phenoxybenzyl alcohol to produce α-cyano-(3-phenoxybenzyl)-2 '-bromoisovalerate, finally, it is condensed with 2-chloro-4-trifluoromethylaniline to produce fluthrin. Preparation method Diα-aminisovaleric acid is brominated with hydrogen bromide to produce α-bromoisovaleric acid. Then it is prepared by reacting with difluoromethylaniline, N-chlorosuccinimide, and then reacting with α-cyano-3-phenoxybenzyl alcohol. Preparation of acid The preparation of alcohol can be seen in the preparation method of cyhalothrin. Synthesis of fluorothrin |
