| Abstract |
The objective of this project was to discover a compound which would effectively and economically control the growth of nuisance species of bluegreen algae and would also exert a minimum impact on the more desirable aquatic life. Acomputer search was made of some 80,000 compounds and thirty-three were selected for testing. Those compounds which gave at least 80% control at 2.0 ppm against both Microcystis aeruginosa and Anabaena flos-aquae, the specified target species of blue-green algae, were selected for secondary screening tests at 1.0,0.5 and 0.1 ppm. Of the thirty-three compounds tested, four were selected for further research in the long-range algaecidal development program. In addition, an organism, Ochromonas ovalis, was discovered whose phagocytic action against Microcystis sp. was enhanced by compounds having algaecidal properties. (Author Modified Abstract) |
