Storage method
Ventilation and low-temperature drying in the warehouse; Separate storage and transportation from food ingredients.
Refrigerate at 0-6 ° C.
Synthetic method
1. 2-phenylbenzoyl chloride is synthesized by reacting 2-phenylbenzoic acid with SOCl2, and then reacted with dimethylformamide to obtain the corresponding 2-phenylbenzoamide. It is then reduced by lithium aluminum hydride to obtain 2-phenyldimethylbenzylamine. 2-phenyldimethylbenzylamine is reacted with CH3I to obtain the corresponding ammonium salt, which is then isomerized and reacted with ethyl chloroformate to obtain 2-methyl-3-phenylchlorobenzyl. Finally, in the presence of KOH, the corresponding acid was refluxed in acetonitrile for 16 hours to obtain bifenthrin. Preparation method 2 is obtained by condensation, cyclization, and dehydrochlorination of 2,3-dimethyl-1-envalerate 2-methyl-3-phenylbromobenzyl bromide
2. Obtained from 3,3-dimethyl-1-envalerate 2-methyl-3-phenylbromobenzyl through condensation, cyclization, and dehydrochlorination.
Main uses
1. Prevent and control more than 20 types of pests, including cotton bollworm, cotton spider, peach fruit moth, pear fruit moth, hawthorn leaf mite, citrus red spider, yellow spot bug, tea winged bug, vegetable aphid, cabbage caterpillar, diamondback moth, eggplant red spider, tea caterpillar moth, greenhouse white planthopper, tea geometrid, and tea caterpillar.
2. Pyrethroid insecticides and acaricides. It has the characteristics of strong knockdown effect, broad-spectrum, high efficiency, fast response, and long residual effect. It mainly has a touch killing effect and gastric toxic effect, without any internal suction effect. It can be used to control cotton bollworm, red bollworm, tea geometrid, tea caterpillar, apple or hawthorn spider, peach fruit moth, vegetable aphid, cabbage worm, vegetable moth, citrus leaf miner, etc. For the prevention and control of cotton bollworm and red bollworm in the second and third generation egg hatching period, before larvae boring into buds and bolls, or for the prevention and control of cotton red spider, in the adult and nymphal mite occurrence period, 10% emulsifiable concentrate 3.4~6mL/100m2 is used to spray 7.5~15KG of water or 4.5~6mL/100m2 is used to spray 7.5~15KG of water. And it can also treat cotton aphids, bridge worms, leaf rollers, moths, thrips, etc. To prevent and control tea geometrid, tea caterpillar and tea moth, spray 10% emulsifiable concentrate with 4000-10000 times of liquid spray.
