Harmful algal blooms (HABs) pose significant threats to freshwater ecosystems worldwide. This study developed an eco-friendly anti-algal agent derived from the bark of Syzygium cumini (L.) and evaluated its efficacy under controlled conditions. The formulation was prepared using natural extracts of bark and applied to algae-contaminated water samples. Over a 15-day period, treated water samples exhibited improvement in water quality parameters and reduced algal growth compared to controls. These findings provide baseline evidence for the potential of plant-based allelochemicals as sustainable alternatives to conventional algicides.
