• Source: Algaecide

Algaecide or algicide is a biocide used for killing and preventing the growth of algae, often defined in a loose sense that, beyond the biological definition, also includes cyanobacteria ("blue-green algae"). An algaecide may be used for controlled bodies of water (reservoirs, golf ponds, swimming pools), but may also be used on land for locations such as turfgrass.




Types






= Inorganic compounds

=
Some inorganic compounds are known since antiquity for their algicidal action due to their simplicity.

Copper(II) sulfate remains "the most effective algicidal treatment". A related traditional use is the Bordeaux mixture, used to control fungus on fruits.
Hydrated lime, as a biocide, is allowed in the production of organic foods.




= Barley straw

=
Barley straw, in England, is placed in mesh bags and floated in fish ponds or water gardens to help reduce algal growth without harming pond plants and animals. Barley straw has not been approved by the United States Environmental Protection Agency (EPA) for use as a pesticide and its effectiveness as an algaecide in ponds has produced mixed results during university testing in the United States and England. It is unclear how straw actually works.




= Synthetic algicides

=
Synthetic algicides include:

benzalkonium chloride – "quat" disinfectant that attacks membranes
bethoxazin – "new broad spectrum industrial microbicide" in 2012, noted as "Canceled in U.S." in 2022 PubChem-EPA query
cybutryne – banned since 2023 in ship paint
dichlone – quinone fungicide/algaecide, not persistent in soil
dichlorophen – also kills invertebrate animals and bacteria
diuron – herbicide/algaecide, inhibits photosynthesis
endothal – herbicide/algaecide, inhibits protein phosphatase 2A
fentin – quinone fungicide/algaecide, discontinued
isoproturon – selective substituted urea herbicide, discontinued
methabenzthiazuron – substituted urea herbicide, discontinued
nabam – fungicide/algicide discontinued in the EU over cancer
oxyfluorfen – herbicide, "very toxic to aquatic life with long lasting effects"
pentachlorophenyl laurate
quinoclamine – herbicide/algicide, not used in most of the EU
quinonamid
simazine – herbicide/algaecide, inhibits photosynthesis
terbutryn
Tiodonium
