ALGAECIDE FOR SUPPRESSING DEVELOPMENT OF CYANOBACTERIA AND GREEN ALGAE BASED ON METABOLITES-HETEROTELERGONE OF AQUATIC PLANTS Russian patent published in 2019 - IPC C02F1/50 A01P13/00 

FIELD: biotechnology.

SUBSTANCE: invention relates to biotechnology, in particular to algaecides based on organic acids – metabolites of aquatic plants, used for treatment of artificial aquatic ecosystems – aquariums, aquaculture pools, in order to selectively inhibit bloom caused by cyanobacteria and green algae and maintain ecosystem development. Described is an algaecide for selective suppression of flowering caused by cyanobacteria and green algae in artificial aquatic ecosystems, characterized by that the composition includes gallic, tetradecanoic, heptanoic, octanoic acids and ethanol, and using a natural mechanism of allelopathy to control development of cyanobacteria and green algae, in the following concentrations, (g/l) (% of active compound): gallic acid C₇H₆O₅ (Gallic acid) – 70 (25); tetradecanoic acid C₁₄H₂₈O₂ (Tetradecanoic acid) – 70 (25); heptanoic acid C₇H₁₄O₂ (Heptanoic acid) – 70 (25); octanoic acid C₈H₁₆O₂ (Octanoic acid) – 70 (25); ethyl alcohol – rest (1 l).

EFFECT: high efficiency of controlling development of cyanobacteria and green algae in aqueous systems and ensuring environmental safety of the algaecide.
