alpha -Amino acid amides of formula (I) wherein the substituents are defined as follows: n is the number zero or one; R1 to R7 are as herein defined; R8 is C1-C6alkyl, C3-C6alkenyl or C3-C6alkynyl; R9 is C3-C8cycloalkyl; a C1-C6alkyl, C3-C6alkenyl or C3-C6alkynyl group substituted by one or more halogen atoms; or a group (a) wherein p and q are identical or different and are each independently of the other the number zero or one; and R13, R14, R15 and R16 are identical or different and are each independently of the others hydrogen or C1-C4alkyl; and X is hydrogen, in which case p and q must have the value zero; phenyl unsubstituted or mono- or poly-substituted by halogen, nitro, cyano, carboxy, C2-C6alkenyl, C2-C6alkynyl, C1-C6haloalkyl, C3-C6alkenyloxy, C3-C6alkynyloxy, C3-C7cycloalkyl, C1-C6haloalcoxy, C1-C6alkylthio, C1-C6alcoxycarbonyl, C3-C6alkenyloxycarbonyl, C3-C6alkynyloxycarbonyl, C1-C6alkyl or by C1-C6alkoxy; cyano; -COOR17; -COR18 or a group (b) wherein R17 and R21 are each independently of the other hydrogen, C1-C6alkyl, C3-C6alkenyl or C3-C6alkynyl, and R18 is hydrogen; C1-C6alkyl, C2-C6alkenyl, C2-C6alkynyl or phenyl, unsubstituted or substituted by halogen, nitro, cyano, C1-C4alkyl or by C1-C4alkoxy, and R19 and R20 are identical or different and are each independently of the other hydrogen or C1-C4alkyl, are valuable microbicides. They can be used in plant protection in the form of suitable compositions, for example in the control of fungal diseases.
