    摘要： 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.
