%X The effect of copper sulfate-ammonia complex on Microcystis aeruginosa (the dominant algae of Cyanobacteria algal bloom) was determined by a 15-day prolonged growth inhibition test in a landscape water sample. Elimination of chlorophyll-a was also studied. The results indicated that copper sulfate-ammonia complex at 0.10 mg·L-1 could completely inhibit the growth of Microcystis aeruginosa at the lag phrase and significantly decrease the concentration of chlorophyll-a in the landscape water sample in 4 days. Copper sulfate-ammonia complex showed a greater algaecidal effect for Microcystis aeruginosa at lag phrase than at log phrase, and a greater elimination effect for chlorophyll-a in the landscape water sample collected in April than in March and May. Therefore, better algaecidal effects can be achieved when the copper sulfate-ammonia complex was applied in early phrase of algal bloom.
