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 trisubstit…
