The invention relates to microbicidal mandelic acid derivatives of the formula I <IMAGE> (I) wherein X is the bridge member -CH= or -N=, Ar is a phenyl, diphenyl or naphthyl group, R1, R2 and R3 independently of one another are hydrogen, nitro, halogen, C1-C3alkyl, C1-C3alkoxy or C1-C3haloalkyl, R is one of the groups <IMAGE> R5 is C2-C10alkenyl which is unsubstituted or substituted by halogen; C2-C10alkynyl which is unsubstituted or substituted by halogen; or is a C3-C8cycloalkyl group or a phenyl group which is unsubstituted or substituted; or is a C1-C12alkyl chain which from C2alkyl may be interrupted by oxygen or sulfur and is unsubstituted or substituted by a member selected from the group consisting of halogen, phenyl, -COO-C1-C4alkyl, -CO-C1-C4alkyl, -CO-phenyl, an unsaturated or saturated 5- or 6-membered ring containing oxygen or sulfur as heteroatom, with each phenyl moiety being unsubstituted or substituted by one or more identical or different halogen atoms, is C1-C10alkyl, or is a phenyl or benzyl group, each unsubstituted or substituted R4 is C1-C12alkyl which is unsubstituted or substituted by halogen or C1-C4alkyl, or is phenyl or benzyl, each unsubstituted or substituted or is the -N(R9)(R10) group, wherein R9 is C1-C6alkyl and R10 is hydrogen, C1-C4alkyl, C1-C4haloalkylsulfenyl, -SC6H5 or -SC(CH3)2CN, and the acid addition salts and metal complexes thereof. |
