Microbicidal compositions Novel 3-aryl-4-cyanopyrrole derivatives of the general formula (I), wherein R1 and R2 are each independently of the other unsubstituted or halogen-substituted alkyl, halogen, nitro or hydrogen, or R1 and R2, when taken together, are -OCF2O, R3 is alkyl, cycloalkyl or benzyl, and R4 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.
