3-Cyano-4-(2,3-dichlorophenyl)pyrrole is suitable for controlling phytopathogenic microorganisms and is markedly superior in activity to preparation of a similar structure. Said compound may be employed for seed dressing, either along or in the form of compositions.

Fungicidal use of a cyanopyrrole derivative and method for producing same

A microbicidal composition comprising at least one microbicidal acylaniline derivative such as metalaxyl, furalaxyl and the like, and H.sub.3 PO.sub.3 or a salt thereof, exerts a synergistically potentiated activity against plant diseases, especially also against acylaniline-resistant pathogens. The composition may optionally comprise a third protective fungicidal component. The three active components may be applied in succession in any order or simultaneously.
