Abstract |
An evaluation of algicides--what they are, their usage, how they are tested, their efficiency, and methods of application--is presented. Detailed are appropriate test organisms, culture and test media, the importance of algicidal versus algestatic effects, and effective chemical concentrations required to achieve potential toxicity. Characteristics of an algal problem, together with its environment, influence the methodology of application processes as well as detoxification, resistance, and synergism. Algal problems of water supply reservoirs and recreational lakes, fish ponds, swimming pools, and cooling towers are specifically discussed with suggestions for effective application of toxicants for their control.
