ABSTRACT:
Pyridines of the formula ##STR1## where R.sup.1 is hydrogen, C.sub.1 -C.sub.6 -alkyl, C.sub.3 -C.sub.6 -alkenyl, C.sub.3 -C.sub.6 -alkynyl or an acyl radical COR.sup.2 ; R.sup.2 is C.sub.1 -C.sub.6 -alkyl, C.sub.3 -C.sub.6 -alkenyl, C.sub.3 -C.sub.6 -alkynyl, C.sub.1 -C.sub.6 -haloalkyl or substituted or unsubstituted aryl; A is one of the groups ##STR2## where R.sup.3 and R.sup.4 are identical or differ and each is C.sub.1 -C.sub.6 -alkyl, with the proviso that R.sup.3 and R.sup.4 are not simultaneously methyl; R.sup.5 is one of the groups (CH.sub.2).sub.n, CH.sub.2 OCH.sub.2, CH.sub.2 S(O).sub.m CH.sub.2, CH.sub.2 CH.sub.2 O or CH.sub.2 CH.sub.2 S(O).sub.m, n denoting 1, 2, 3, 4 or 5, and m being 0, 1 or 2; Ar is aryl which is unsubstituted or bears from one to five substituents selected from the group consisting of C.sub.1 -C.sub.6 -alkyl, phenyl, halogen, C.sub.1 -C.sub.6 -haloalkyl, C.sub.1 -C.sub.6 -alkoxy, C.sub.1 -C.sub.6 -haloalkoxy, C.sub.1 -C.sub.6 -alkoxyiminocarbyl, phenoxy, halophenoxy and benzyloxy, and the N-oxides and plant-tolerated acid addition salts thereof, and fungicides containing these compounds.
