A simple extraction method was applied to control four selected cyanobacteria, solitary (SMA) and colonial Microcystis aeruginosa (CMA), and green algae, Scenedesmus quadricauda and Chlorella vulgaris using a domestic plant and mineral. Three kinds of concentrations (1, 5, and 10 mg $L^{-1}$) of three fresh plants Camellia sinensis, Quercus acutissima, and Castanea crenata, three minerals loess, quartz porphyry, and natural zeolite, and plant-mineral composite, totally seven materials were prepared with the simple extraction processes: drying and grinding of material, water-extraction by high temperature-sonication and filtering. Cyanobacteria SMA and CMA (over 60% of control) were effectively inhibited with the low concentration (1 mg $L^{-1}$) of plants Q. acutissima and C. crenata and natural zeolite, while green alga S. quadricauda (below 50% of control) also retarded in growth. Low concentrations (1 mg $L^{-1}$) of C. sinensis effectively increased the growth of C. vulgaris, while loess also induced the algal growth of S. quadricauda. Therefore, our results indicate that crude extract of domestic plants, Q. acutissima and C. crenata can be also useful to control the cyanobacterial bloom in eutrophic lake, whereas C. sinensis and loess may be a good growth factor or useful media for the algal mass culture.
