The cyanobacteria blooms caused by eutrophication has received widespread attention in recent years，which endanger the environment，destroy ecological environment and affect the normal life of human beings. The control of cyanobacterial blooms is one of the important issues to be solved at present. The chemical method of adding algaecide is very effective for timely control of cyanobacteria blooms. However，few studies have comprehensively summarized the practical application of common algaecides despite the attention given to their development. Some algaecides which have received much attention in recent years for the typical species of cyanobacteria were focused on. For Microcystis aeruginosa， a typical cyanobacteria， the algicidal effect，the working mechanism，the effect on the microcystin（MC），and the practical applications of these algaecides were reviewed. It was hoped to provide guidance for the selection of algaecides. Moreover，the potential risks of excessive background concentrations of allelopathic substances and long-term use of non-allelopathic substances have also been noted. Considering the algicidal effect and safety，the characteristics of the ecologically friendly algaecide were summarized. Additionally，strategies such as slow release and combined use were proposed to address current algaecide limitations.
