Abstract
Benzimidazolesulfonic acid derivatives of the formula I ##STR1## in which R.sub.1 is an unsaturated 5-membered heterocycle having not more than two hetero atoms N and/or S or is an unsaturated 6-membered heterocycle having not more than two N atoms, it being possible for each of the heterocycles to be substituted, and X is oxygen or sulfur, while R.sub.2, R.sub.3, R.sub.4 and n are as defined herein, are valuable microbicides. They can be used in crop protection in the form of suitable compositions, for example for controlling fungal disease.
