PS/5-17627/= Microbicidal compositions Abstract of the Disclosure Novel benzothiophene and benzofuran derivatives of the general formula I (I) Image wherein X is oxygen or sulfur9 Rl is hydrogen, halogen, C1-C4alkyl or C1-C4haloalkyl, R2 is hydrogen, halogen, C1-C4alkyl or C1-C4haloalkyl, R3 is hydrogen, C1-C4alkyl or halogen and R is a 4-cyano-3-pyrrole radical of which the N atom carries one of the following substituents: A: hydrogen or CO-R4 in which R4 is unsubstituted C1-C6alkyl or C1-C6- alkyl substituted by halogen or by C1-C3alkoxy; C3-C6alkenyl, C3-C6- alkynyl, unsubstituted C1-C6alkoxy or C1-C6alkoxy substituted by halogen or by C1-C3alkoxy; C3-C6alkenyloxy, C3-C6cycloalkyl or tetrahydrofur- 2-yl; B: S-R5 in which R5 is C1-C3haloalkyl; C: CH(Y)R6 in which R6 is hydrogen or C1-C8haloalkyl and Y is hydroxy, halogen or OC(O)R7 in which R7 is C1-C8alkyl, C1-C8haloalkyl, C2-C6- alkenyl, 2-tetrahydrofuryl, 2-tetrahydropyranyl or Cl-C6alkoxycarbonyl; D: CH2-Z in which Z is one of the groups a) Image or b) Image or c) Image wherein R8 and R9 are each, independently of the other, hydrogen, unsub- stituted C1-C6alkyl or C1-C6alkyl substituted by cyano or by C1-C6alkoxy- carbonyl; C3-C6alkenyl, C3-C6alkynyl, C3-C7cycloalkyl, unsubstituted phenyl or phenyl substituted by halogen, by C1-C6alkyl, by C1-C6haloalkyl and/or by C1-C6alkoxy, with the proviso that only R8 or R9 may be hydrogen; R10 and R11 are each, independently of the other, hydrogen, C1-C6alkyl or C1-C6alkoxycarbonyl; R12 and R13 are each, independently of the other, hydrogen, C1-C6alkyl or C1-C6alkoxycarbonyl; and R15 is oxygen, sulfur, Image or Image , wherein R14 is hydrogen, C1-C6alkyl, formyl, C1-C6alkanoyl or C1-C6alkoxycarbonyl; and n is one of the numbers 0 or 1. The novel active ingredients serve to control harmful microorganisms, especially phytopathogenic fungi. They can be used together with suitable formulation adjuvants in the form of compositions, and are suitable also for preventing attack on cultivated plants by harmful microorganisms.
