Abstract
.alpha.-Azolyl-.beta.-hydroxy-ketones of the formula ##STR1## in which R.sup.1 represents optionally substituted alkyl or optionally substituted phenyl, R.sup.2 represents the grouping --CX.sup.1 X.sup.2 R.sup.3 or alkoxycarbonyl, R.sup.3 represents halogen, halogenoalkyl or optionally substituted phenyl, X.sup.1 and X.sup.2, which may be identical or different, each represents hydrogen or halogen, and Y represents a nitrogen atom or the CH group, or physiologically acceptable acid-addition salts or metal-salt complexes thereof which possess fungicidal properties.
