Abstract

Disclosed are pyrethroid compounds represented by formula (A), or their stereo chemical isomers, or the mixture of such isomers, and the preparation process thereof and the use thereof for killing pests. In the formula (A), R1 is methoxymethyl (-CH2OCH3) or H; and R2 is -CF3 or -COOCH(CF3)2. The test proves that the present compounds show better effect for repelling and controlling pests such as mosquito, musca and German cockroach.

Abstract

Disclosed is an optically active pyrethroid compound represented by general formula (A), preparation process thereof and the use thereof for preventing insect pests. The compound is dextrogyrate simple optical isomer, wherein R1and R2 is respectively same or different halogen. The present compound shows better insecticidal effect compared with that of the prior art.
