Abstract
The invention relates to new 2-cyanobenzimidazole derivatives. These compounds correspond to the formula (I): ##STR1## in which: n is 0, 1, 2 or 3, PA0 R is halogen; optionally halogen-substituted lower alkyl or alkylthio; lower alkoxy optionally substituted by one or more halogens or by the phenyl radical; lower alkenyl; lower alkynyl; amino optionally substituted by one or two alkyls; NO.sub.2 --; CN--; CNO--; NCS--; , SCN--; lower alkylsulphonyl; sulphamoyl optionally substituted by one or two alkyls; lower alkylsulphinyl; optionally substituted acyl; or alkoxycarbonyl, and PA0 R' is optionally halogen-substituted lower alkyl, amino optionally substituted by one or two alkyl radicals, or a nitrogen atom substituted by two radicals forming a heterorcyclic ring with this nitrogen atom, the heterocyclic ring containing from 4 to 6 ring members and from 1 to 3 hetero-atoms in the ring. They can be used in agriculture, in particular for combating phytopathogenic fungi and for combating mites.
