Abstract: The invention relates to novel 3-phenyl-4-cyanopyrrole derivatives of the general formula ##STR1## wherein X has the following meanings:A: hydrogen or CO--R.sub.1, wherein R.sub.1 is C.sub.1 -C.sub.6 alkyl which is unsubstituted or substituted by halogen or C.sub.1 -C.sub.3 alkoxy; or is C.sub.3 -C.sub.6 alkenyl, C.sub.3 -C.sub.6 alkynyl, or C.sub.1 -C.sub.6 alkoxy which is unsubstituted or substituted by halogen or C.sub.1 -C.sub.3 alkoxy; or is C.sub.3 -C.sub.6 alkenyloxy, C.sub.3 -C.sub.6 cycloalkyl, or tetrahydrofur-2-yl;B: S--R.sub.2, wherein R.sub.2 is C.sub.1 -C.sub.3 haloalkyl;C: CH(Y)R.sub.3, wherein R.sub.3 is hydrogen or C.sub.1 -C.sub.8 haloalkyl and Y is hydroxy, halogen or OC(O)R.sub.4, wherein R.sub.4 is C.sub.1 -C.sub.8 alkyl, C.sub.1 -C.sub.8 haloalkyl, C.sub.2 -C.sub.6 alkenyl, or C.sub.1 -C.sub.6 alkoxycarbonyl; orD: CH.sub.2 --Z, wherein Z is the group ##STR2## wherein each of R.sub.7 and R.sub.8 independently of the other is hydrogen, C.sub.1 -C.sub.6 alkyl or C.sub.1 -C.sub.6 alkoxycarbonyl, or both together form a fused aromatic ring; each of R.sub.9 and R.sub.10 independently of the other is hydrogen, C.sub.1 -C.sub.6 alkyl or C.sub.1 -C.sub.6 alkoxycarbonyl; and X is oxygen, sulfur, ##STR3## wherein R.sub.11 is hydrogen, C.sub.1 -C.sub.6 alkyl, formyl, C.sub.1 -C.sub.6 alkanol or C.sub.1 -C.sub.6 alkoxycarbonyl; and n is 0 or 1.The novel compounds are used for controlling harmful microorganisms, in particular phytopathogenic fungi. They can be employed together with suitable formulation adjuvants as compositions and are also suitable for protecting cultivated plants from attack by harmful microorganisms.
