This disclosure relates to a novel class of 2-alkyl-3-haloisothiazolium salts. These salts have been found to be useful in controlling the growth of bacteria and fungi. They have also been found to be useful intermediates in the preparation of novel and known antibacterial and antifungal compounds.
