The invention relates to the use of (hetero)cyclylcarboxamides of general formula (I) and to the agriculturally useful salts thereof for controlling plant pathogenic fungi, the variables in formula (I) having the following designations: A represents phenyl or an at least monosaturated five-membered or six-membered heterocycle with 1, 2 or 3 heteroatoms as ring members selected from N, O, S, S(═O) and S(═O)2, where phenyl and the at least monosaturated five-membered or six-membered heterocycle can be unsubstituted or substituted according to the description; Y represents oxygen or sulphur; R1 represents H, OH, alkyl, cycloalkyl, alkoxy, halogenalkyl, halogencycloalkyl or halogenalkoxy; R2 and R3 represent H, halogen, nitro, CN, alkyl, cycloalkyl, alkenyl, alkinyl, alkoxy, halogenalkyl, halogencycloalkyl, halogenalkenyl, halogenalkinyl or halogenalkoxy; R4 represents halogen, nitro, CN, alkyl, cycloalkyl, alkenyl, alkinyl, alkoxy, halogenalkyl, halogencycloalkyl, halogenalkenyl, halogenalkinyl or halogenalkoxy; R5 represents hydrogen, halogen, nitro, CN, OH, alkyl, cycloalkyl, alkenyl, alkinyl, alkoxy, alkenyloxy, alkinyloxy, alkoxyalkoxy, halogenalkyl, halogencycloalkyl, halogenalkenyl, halogenalkinyl or halogenalkoxy; alklthio, halogenalkylthio, alkylsulfinyl, halogenalkylsulfinyl, alkylsulfonyl, halogenalkylsulfonyl, —(CR6)═NOR7, —C(O)R8, NR9R10, —C(O)NR9R10, —C(S)NR9R10, phenyl or phenylalkyl, the phenyl ring in the last two radicals optionally comprising between 1 and 4 of the radicals cited for R4; R6, R7, R8, R9 and R10 have the designations cited in the description; the two radicals R4 and R5 bound to adjacent carbon atoms can also represent an alkylene chain with 3 to 5 members, wherein 1 or 2 non-adjacent CH2 groups can also be replaced by O or S, and part or all of the hydrogens can be replaced by halogen; Ar represents phenyl, naphtyl or a five-membered or six-membered heteroaromatic radical with 1, 2 or 3 heteroatoms as ring members selected from N, O, and S, that can optionally also carry a fused benzene ring; and n represents 0, 1, 2, 3, or 4. The invention also relates to crop protection agents containing said compounds.
