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, 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 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.
这项发明涉及新的2-氰基苯并咪唑衍生物。这些化合物对应于以下式子(I):##STR1##其中:n为0、1、2或3,R为卤素;可选择卤素取代的较低烷基或烷硫基;较低烷氧基,可选择由一个或多个卤素或苯基基团取代;较低烯基;较低炔基;氨基,可选择由一个或两个烷基取代;NO.sub.2--; CN--; CNO--; NCS--; , SCN--; 较低烷基磺酰基;磺酰胺,可选择由一个或两个烷基取代;较低烷基亚砜基;可选择取代的酰基;或烷氧羰基,R'为可选择卤素取代的较低烷基,氨基,可选择由一个或两个烷基基团取代,或由两个形成杂环的基团取代的氮原子,该杂环含有4至6个环成员和1至3个环内杂原子。它们可以在农业中使用,特别是用于对抗植物病原真菌和对抗螨虫。
