A pyrazole derivative represented by the formula (1)is low in toxicity and persistence and yet has an extremely high insecticidal efficacy
wherein A is CH, N or C-halogen atom, R1 is hydrogen atom, lower alkyl, lower haloalkyl, benzyl or phenyl, R2 is lower alkyl, lower haloalkyl, lower alkenyl, lower alkynyl, benzyl or phenyl, R3 is hydrogen atom, halogen atom, lower alkyl, lower haloalkylthio, phenyl, cyano, nitro or amino, R4 is halogen atom, R5 is lower haloalkyl, R6 is hydrogen atom, lower alkyl, lower haloalkyl or benzyl, R1 and R6 being not hydrogen atoms at the same time, l is 0 or 1, m is 0 or 1 and n is a number of 0 to 2.
由式(1)表示的吡唑衍生物毒性低、持久性强,但杀虫效力极高
其中 A 是 CH、N 或 C-卤素原子,R1 是氢原子、低级烷基、低级卤代烷基、苄基或苯基,R2 是低级烷基、低级卤代烷基、低级烯基、低级炔基、苄基或苯基,R3 是氢原子、卤素原子、低级烷基、低级卤代烷基硫基、苯基、氰基、硝基或氨基,R4 是卤素原子、R4为卤素原子,R5为低级卤代烷基,R6为氢原子、低级烷基、低级卤代烷基或苄基,R1 和 R6 不能同时为氢原子,l 为 0 或 1,m 为 0 或 1,n 为 0 至 2 的数字。
