Abstract:
New phenoxypyridylmethyl esters of the general formula ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 have the meaning given in the description andR represents the radical ##STR2## wherein R.sup.4 and R.sup.5 have the meaning given in the description, and represents the radical ##STR3## wherein R.sup.6 and R.sup.7 have the meaning given in the description, are obtained by a process in which carboxylic acids of the general formulaR--COOH (II)wherein R has the meaning given previously, or reactive derivatives of these acids, are reacted with phenoxypyridyl alcohols of the general formula ##STR4## wherein R.sup.1, R.sup.2 and R.sup.3 have the meaning given above, or with reactive derivatives of these alcohols, if appropriate in the presence of acid acceptors, if appropriate in the presence of catalysts and if appropriate in the presence of diluents. The new phenoxypyridylmethyl esters of the formula (I) are distinguished by a high pesticidal, particularly insecticidal and acardicidal activity.

Abstract:
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, andR.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 formulaR.sup.1 --N.dbd.C.dbd.O (III)or with a carbamoyl halide of the general formulaR.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.
