Abstract

Sulphonyloxadiazolones of the formula ##STR1## in which A represents a single bond or represents alkanediyl, alkenediyl, alkinediyl or a grouping --*O--CH.sub.2 --, --*O--CH.sub.2 --CH.sub.2 --, --*CH.sub.2 --O--, --*CH.sub.2 --O--CH.sub.2 --CH.sub.2 --, --*CH.sub.2 --S--, --*S--CH.sub.2 --, ##STR2## or ##STR3## where the atom labelled by * is in each case attached to R.sup.1 and PA0 R.sup.3 represents hydrogen or alkyl, PA0 R.sup.1 represents hydrogen, optionally substituted cycloalkyl, optionally substituted cycloalkenyl, optionally substituted aryl or optionally substituted heterocyclyl and PA0 R.sup.2 represents in each case optionally substituted alkyl, alkenyl, dialkylamino, aryl or heterocyclyl, are highly suitable for controlling undesirable microorganisms in crop protection and in the protection of materials. PA0 Novel sulphonyloxadiazolones of the formula ##STR4## in which A and R.sup.1 are as defined above and PA0 R.sup.4 represents optionally substituted alkyl, optionally substituted alkenyl, dialkylamino, nitro-substituted phenyl which may also contain one or two further substituents, or represents optionally substituted heterocyclyl, but where R.sup.4 does not represe…
