MICROBICIDAL AGENTS A B S T R A C T 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-benziso- thiazole 1,1-dioxide of the formula Image in which R1 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 represent cyclo- alkyl having 5 or 6 carbon atoms, or represents hetero- cyclic structures which are optionally saturated or unsaturated, are optionally monosubstituted to tetra- substituted by alkyl having 1 to 4 carbon atoms or hydroxyl, and have 1 to 3 identical or different hetero- atoms, and a total of 5 or 6 ring members, R2 represents alkyl having 1 to 18 atoms, or alkyl which - 2 - has 1 to 6 carbon atoms and is optionally monosubstituted to trisubstituted by hydroxyl and/or monosubstituted to trisubstituted by amino, or represents carboxyl-sub- stituted 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 caron atoms, or represents heterocyclic struc- tures 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 9 and R3 represents hydrogen, alkyl, having 1 to 6 carbon atoms, NH2, Image , benzyl, or hydroxyalkyl having 1 to 3 carbon atoms, with the exception of the mono-, di- and triethanolamine compounds, or R1 and R2 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.
