The effects of five natural products on the growth of three harmful algae species including C hattonella marina H ara et C hihara, A lexandrium tamarense B alech and K arenia mikimotoi ( M iyake & K ominami ex O da) G . H ansen & Ø . M oestrup were observed. Four products including ε ‐polylysine, betaine, stachydrine and berberine exhibited selectively inhibitory effects against the three algae. However, the other product chitosan had no obvious inhibition against the above algae. Berberine and ε ‐polylysine exhibited relatively higher inhibitory capability against C . marina , and betaine had the highest inhibitory effect against A . tamarense . While only berberine could effectively inhibit the growth of K . mikimotoi with LC 50 , 120 at 3.1 mg/L. The fast inhibitory effect against K . mikimotoi and environmental safety of berberine suggested that it might be a potential algaecide against K . mikimotoi .
