Abstract
Novel pyrrole derivatives of formula (I) wherein X is oxygen or sulfur; R1 is C1-C4alkyl unsubstituted or substituted, with the exception of CF3; C3-C6cycloalkyl unsubstituted or substituted; or halogen; R2 is hydrogen, C1-C4alkyl unsubstituted or substituted, C1-C4alkoxy unsubstituted or substituted, cyano or halogen; R3 is C1-C4alkyl unsubstituted or substituted; and A is orthosubstituted aryl; orthosubstituted heteroaryl; bicycloaryl unsubstituted or substituted; or bicycloheteroaryl unsubstituted or substituted. The novel compounds have plant-protective properties and are suitable for protecting plants against infestations by phytopathogenic microorganisms.
