This review paper provides an assessment of nuisance aquatic plants and the problems associated with their control in the United States. Major emphasis is given to the sun belt states where aquatic plant control is critical due to introduction of exotic plants and extended growing season. The impact of aquatic plants (algae, non-native and native plants) and their management techniques are discussed as they pertain to water quality and aquatic life. Herbicide residue data, both in the soil and water, and herbicide toxicity to aquatic organisms are presented and discussed. The chronic or long-term effects of herbicide on aquatic organisms have not been fully investigated. Current information indicated that non-fatal physiological changes might cause mortality in test organisms if the organisms are exposed repeatedly. Effects of vegetation removal are discussed. Major research needs are identified for development of environmentally safe aquatic plant management programs.
