异构体

The bioassays showed that the inhabitation rate of the mixture of two isomers, Z isomer and E isomer were reached 95%, 100% and 97% against Sphaerotheca fuliginea at 50 mg/L. The inhabitation rate of them was similar, so the mixture of the two isomers can be used without separation.

结果表明，当处理剂量为50 mg/L时，氯苯肟唑、Z-氯苯肟唑和E-氯苯肟唑的防效分别为95%、100%和97%，三者活性基本相当，故在实际中无须将两个异构体分离，混合体可直接应用。
