Abstract

Substituted 1-azolyl-but-2-ones and -2-ols of the formula ##STR1## in which B is --CO-- or --CH (OH)-- PA1 Az represents a 1,2,4-triazol-l-yl or -4-yl or imidazol-l-yl radical, PA1 R.sup.1 represents a hydrogen atom, an alkyl, alkenyl, alkinyl, optionally substituted cycloalkyl, optionally substituted cycloalkylalkyl, optionally substituted phenoxyalkyl or optionally substituted aralkyl radical, PA1 n is 0 or 1, PA1 R.sup.2 represents a cyano radical or a grouping of the general formula --X--R.sup.3 or --CO--NR.sup.4 R.sup.5, or, if n does not represent 0 at the same time as R.sup.1 preresents a hydrogen atom and Az represents a 1,2,4-triazolyl radical, PA1 R.sup.2 also additionally represents an optionally substituted aryl or alkoxycarbonyl radical, and wherein PA1 X represents an oxygen or sulphur atom or an SO or SO.sub.2 group, PA1 R.sup.3 represents an alkyl, halogenoalkyl, optionally substituted aryl or optionally substituted aralkyl radical, PA1 R.sup.4 represents a hydrogen atom or an alkyl or optionally substituted aryl radical, and PA1 R.sup.5 represents a hydrogen atom or an alkyl radical, or acid addition salts or metal salt complexes thereof, which possess fungicidal a…
