This invention offers an effective method of inhibiting the growth of toxic bloom algae caused by cyanobacteria Mycrocystis aeruginosa in freshwater environments comprising administering an effective amount of 5,6-dichlorogramine to the freshwater. Also, the invention offers an effective method of inhibiting the growth of toxic bloom algae caused by M. aeruginosa comprising administering an effective amount of 5,6,7-trichlorogramine to the freshwater. Both compounds, 5,6-dichlorogramine and 5,6,7-trichlorogramine, may be administered individually or in combination to the freshwater. Both compounds are individually very potent and only need to be administered at a very low concentration to be effective at inhibiting the growth of M. aeruginosa in freshwater environments. Both 5,6-dichlorogramine and 5,6,7-trichlorogramine are each individually effective at inhibiting M. aeruginosa at low concentrations, between about 0.01 mg/L and about 0.05 mg/L, or more specifically at a concentration of about 0.03 mg/L. Also, both 5,6-dichlorogramine and 5,6,7-trichlorogramine individually have long potency durations, needing to be added no more frequently than once every 60 days to freshwater to inhibit the growth of M. aeruginosa.
本发明提供了一种有效的方法,用于抑制淡水环境中由蓝藻微囊藻(Mycrocystis aeruginosa)引起的有毒藻类水华的生长,包括向淡水中投入有效量的5,6-二氯格拉明。此外,本发明还提供了一种有效的方法,用于抑制由M. aeruginosa引起的有毒藻类水华的生长,包括向淡水中投入有效量的5,6,7-三氯格拉明。这两种化合物,5,6-二氯格拉明和5,6,7-三氯格拉明,可以单独或联合向淡水中投入。这两种化合物分别非常有效,只需要以非常低的浓度投入即可在淡水环境中抑制M. aeruginosa的生长。5,6-二氯格拉明和5,6,7-三氯格拉明都在低浓度下单独有效,浓度在约0.01 mg/L至约0.05 mg/L之间,或更具体地在约0.03 mg/L的浓度下有效抑制M. aeruginosa的生长。此外,5,6-二氯格拉明和5,6,7-三氯格拉明单独具有长效持久性,只需每60天向淡水中添加一次即可抑制M. aeruginosa的生长。
