Slimicide (or antislime agent)^[1] is a broad-spectrum antimicrobial pesticide used to kill slime-producing microorganisms such as algae, bacteria, fungi, and slime molds.^[2][3] One primary application domain is in the papermaking industry, where it reduces the occurrence of paper holes and spots,^[4][5] as well as protecting the machinery from odor,^[4][6] clogs,^[6] corrosion,^[4][6] and breakdown. Slimicides come in variants effective in acidic and/or alkaline media,^[4][5] in liquid or solid form,^[6][7] and are based on chemicals such as aldehydes,^[4] bromium or quaternary ammonium compounds,^[8] and others.^[8] Additional significant application areas for slimicides include industrial water recirculation systems^[9] such as cooling towers,^[5] fuel storage tanks and wells,^[5][10] and in conjunction with fluids used for oil extraction.^[5][7] In some application domains, slimicides may be formulated specifically to target slime molds.^[2][3]
