Abstract
A method of combating fungi and bacteria which comprises applying to such fungi, bacteria or a habitat thereof, a fungicidally or bactericidally effective amount of at least one salt of 3-keto-2-, 3H-1,2-benzisothiazole 1,1-dioxide of the formula ##STR1## in which R.sup.1 represents hydrogen, alkyl having 1 to 18 carbon atoms, or alkyl which has 1 to 6 carbon atoms and is optionally monosubstituted to trisubstituted by hydroxyl and/or monosubstituted to trisubstituted by amino, or represents carboxyl-substituted alkyl having 1 to 4 carbon atoms, or phenyl which is optionally monosubstituted to trisubstituted by identical or different substituents from amongst nitro and chlorine, or represents cycloalkyl having 5 or 6 carbon atoms, or represents heterocyclic structures which are optionally saturated or unsaturated, are optionally monosubstituted to tetrasubstituted by alkyl having 1 to 4 carbon atoms or hydroxyl, and have 1 to 3 identical or different heteroatoms, and a total of 5 or 6 ring members, R.sup.2 represents alkyl having 1 to 18 atoms, or alkyl which has 1 to 6 carbon atoms and is optionally monosubstituted to trisubstituted by hydroxyl and/or monosubstituted to trisubstituted by amino, or represents carboxyl-substituted alkyl having 1 to 4 carbon atoms, or phenyl which is optionally monosubstituted to trisubstituted by identical or different substituents from amongst nitro and chlorine, or represent cycloalkyl having 5 or 6 carbon atoms, or represents heterocyclic structures which are optionally saturated or unsaturated, are optionally monosubstituted to tetrasubstituted by alkyl having 1 to 4 carbon atoms or hydroxyl, and have 1 to 3 identical or different heteroatoms, and a total of 5 or 6 ring members, and R.sup.3 represents hydrogen, alkyl, having 1 to 6 carbon atoms, NH.sub.2, ##STR2## benzyl, or hydroxyalkyl having 1 to 3 carbon atoms, with the exception of the mono-, di- and triethanolamine compounds, or R.sup.1 and R.sup.2 together with the nitrogen atom at which they are located, form a 5-membered or 6-membered ring which can optionally contain further heteroatoms, and can optionally be substituted by keto groups or fused-on 5-membered or 6-membered rings and/or alkyl having 1 to 4 carbon atoms, with the exception of the pyridine ring which is optionally mono- or disubstituted by methyl.
