New pyrazol-4-yl N-alkylcarbamates of the general formula ##STR1## in which R.sup.1 represents an optionally substituted alkyl group having more than one carbon atom or an alkenyl, alkinyl or cycloalkyl group, and R.sup.2 represents an optionally substituted alkyl, alkenyl, alkinyl, cycloalkyl, aralkyl or aryl group, can be obtained if a 4-hydroxypyrazole of the general formula ##STR2## is reacted with an isocyanate of the general formula R.sup.1 --N.dbd.C.dbd.O (III) or with a carbamoyl halide of the general formula R.sup.1 --NH--CO--Hal (IV). The new compounds are distinguished by a high degree of activity as pest-combating agents, in particular by their insecticidal and nematicidal activity.
通式为##STR1##的新型吡唑-4-基N-烷基氨基甲酸酯可以通过将通式为##STR2##的4-羟基吡唑与通式为R.sup.1 --N.dbd.C.dbd.O (III)的异氰酸酯或通式为R.sup.1 --NH--CO--Hal (IV)的氨基甲酸酯反应而得到,其中R.sup.1代表有一个或多个碳原子的可选取代烷基或烯基、炔基或环烷基,R.sup.2代表可选取代烷基、烯基、炔基、环烷基、芳基或aryl基。这些新化合物因其高度活性而作为杀虫剂和线虫灭活剂具有很高的活性。
