Novel 3-aryl-4-cyanopyrrole derivatives of the general formula ##STR1## wherein R.sub.1 and R.sub.2 are each independently of the other unsubstituted or halogen-substituted alkyl, halogen, nitro or hydrogen, or R.sub.1 and R.sub.2, when taken together, are --OCF.sub.2 O, R.sub.3 is alkyl, cycloalkyl or benzyl, and R.sub.4 is hydrogen or an alkali metal or alkaline earth metal. The novel compounds are used for controlling harmful microorganisms, in particular phytopathogenic fungi. They can be used together with suitable formulation assistants as compositions, and are also suitable for preventing infestation of cultivated plants by harmful microorganisms.
新型3-芳基-4-氰基吡咯衍生物的一般式为##STR1##其中R.sub.1和R.sub.2各自独立地为未取代或卤素取代的烷基,卤素,硝基或氢,或当R.sub.1和R.sub.2一起取时,为--OCF.sub.2 O,R.sub.3为烷基,环烷基或苄基,R.sub.4为氢或碱金属或碱土金属。这些新化合物用于控制有害的微生物,特别是植物病原真菌。它们可以与适当的配方助剂一起用作组合物,并且也适用于防止有害微生物对栽培植物的侵害。
