Harmful algal blooms (HABs) are a severe hazard to human health in drinking water and freshwater ecosystems. Several methods including chemical, physical, mechanical, and biological strategies have been applied in HABs control. Nevertheless, the use of those strategies is generally not efficient because of their unforeseen ecological consequences, high costs, energy-intensive, and low efficiency. Recently, the application of natural substances such as volatile compounds is a promising eco-friendly alternative solution for harmful algae control in aquatic ecosystems. Through this work, we evaluated the potential algicidal activities of the essential oils from Cedrus atlantica, Pistacia atlantica and Schinus molle against a toxin-producing strain of Microcystis aeruginosa and an environmental strain of Chlorella sp. The essential oils composition was assessed by GC-MS. The anti-microalgal potential was evaluated qualitatively using the disc diffusion method, and quantitatively using the broth microdilution assay. The minimum cyanobactericidal and algicidal effects were also evaluated. The highest potential in solid media was showcased by Cedrus atlantica essential oils, whereas it was demonstrated by Pistacia atlantica in liquid media.
