Pesticidal compsn

HU--44005 A A pesticidal compsn. comprises a carbamic acid ester deriv. - of formula (I) as active ingredient in association with an inert carrier material. - In (I) R1 = 1-4C alkyl; R2 = 1-4C alkyl or when X = 1-12C alkyl, R2 = 1-2C alkyl; R3 = H, Me or H; n = R5 = H or halogen; n = 0, 1 or 2; X = 1-12C alkyl or 4-aryloxyphenoxyalkyl of formula (II). Also claimed is The present invention relates to pesticides containing carbamic acid ester derivatives of the formula (I), (I) to pesticide compositions containing these compounds and to a process for their preparation. In the general formula R1 is alkyl of from one to four carbon atoms R2 represents alkyl of from one to four carbon atoms or (when X is alkyl of from one to twelve carbon atoms) alkyl of from one to twelve carbon atoms R3 is H, methyl or ethyl R4 and R5 are, independently from each other, H or halogen atoms n=0, 1 or 2 X represents alkyl of from one to twelve carbon atoms or an 4-aryloxyphenoxyalkyl group of formula (II). (II) The pesticide of the invention can be used for controlling insects and mites.
