Fungicidal pyridinylpyrimidines of the formula ##STR1## in which R.sup.1 represents hydrogen, halogen, alkoxy, alkylthio, halogenoalkyl, amino or dialkylamino, where, in the case of dialkylamino, the two radicals may, together with the nitrogen to which they are bonded, form a 5- to 7-membered, saturated or unsaturated ring which optionally contains a further hetero atom and which is optionally substituted by 1 or 2 alkyl groups; or R.sup.1 represents in each case optionally substituted aryloxy, arylthio, aralkyloxy or aralkylthio, R.sup.2 and R.sup.3 are independent of one another and are identical or different and in each case represent hydrogen, halogen, alkyl, halogenoalkyl, alkoxy, alkylthio or alkoxycarbonyl, or R.sup.2 and R.sup.3 together represent anaylene chain having 3 to 6 carbon atoms which are linked via the ring positions 3 and 4 or 4 and 5, R.sup.4 represents hydrogen, halogen, alkyl, halogenoalkyl, hydroxyl, alkoxy, mercapto, alkylthio, amino or (di)alkylamino, where, in the case of dialkylamino, the two radicals may, together with the nitrogen atom to which they are bonded, form a 5- to 7-membered, 4-phenyl-2-(2-pyridyl)-pyrimidine and 4-chloro-6-phenyl-2-(2-pyridyl)-pyrimidine (disclosed in J. Org. Chem. 32 (5), 1591-6 (1967)). Furthermore, it has been found that the new pyridinylpyrimidine derivatives of the formula (I) ##STR2## in which R.sup.1 represents hydrogen, halogen, alkoxy, alkylthio, halogenoalkyl, amino or dialkylamino, where, in the case of dialkylamino, the two radicals may, together with the nitrogen atom to which they are bonded, form a 5- to 7-membered, saturated or unsaturated ring which optionally contains a further hetero atom and which is optionally substituted by 1 or 2 alkyl groups; in which furthermore R.sup.1 represents in each case optionally substituted aryloxy, arylthio, aralkyloxy or aralkylthio, R.sup.2 and R.sup.3 are independent of one another and are identical or different and in each case represent hydrogen, halogen, alkyl, halogenoalkyl, alkoxy, alkylthio or alkoxycarbonyl, or R.sup.2 and R.sup.3 together represent an alkylene chain having 3 to 6 carbon atoms which are linked via the ring positions or R.sup.2 and R.sup.3 together represent an alkylene chain having 3 to 6 carbon atoms which are linked via the ring positions 3 and 4 or 4 and 5, R.sup.5 represents hydrogen or alkyl and Ar represents unsubstituted or substituted aryl,
