Abstract

The present invention relates to a process for preparing tetrazole-substituted anthranilamide derivatives of the formula (I)in which R1, R2, R3, R4, R5 and Z are each as defined in the description, and to a novel crystal polymorph of these derivatives and to the use thereof in agrochemical formulations.
