Silyl-benzimidazole-2-carbamic acid esters of the formula I ##STR1## where Y and Z are hydrogen or a silyl radical of the formula ##STR2## where R.sup.1, R.sup.2 and R.sup.3 independently of one another are unsubstituted or halogen-substituted alkyl, alkenyl or alkynyl of up to 12 carbon atoms, cycloalkyl of up to 7 carbon atoms which is unsubstituted or substituted by alkyl or alkynyl of up to 4 carbon atoms, or phenyl which is unsubstituted or substituted by halogen or alkyl of up to 4 carbon atoms, and R is alkyl of up to 4 carbon atoms, with the proviso that Y and Z are not both hydrogen, and their use as fungicides. The new active ingredients are particularly suitable for combating harmful phycomycetes, ascomycetes and fungi imperfecti.
化合物I的硅基苯并咪唑-2-羧酸酯的结构式为:##STR1## 其中,Y和Z为氢原子或式为##STR2##的硅基基团,其中R.sup.1,R.sup.2和R.sup.3分别独立地为未取代或卤素取代的碳数不超过12的烷基,烯基或炔基,碳数不超过7的环烷基,该环烷基未取代或取代为碳数不超过4的烷基或炔基,或为未取代或取代为卤素或碳数不超过4的烷基的苯基,R为碳数不超过4的烷基,但须满足Y和Z不同时为氢原子。该新活性成分特别适用于对抗有害的浅菌类、子囊菌类和不完全真菌。其用作杀菌剂。
