Abstract

Minnesota lakes have an invasive species problem: invasives are outcompeting our native plants and causing ecological degradation. Herbicides are used in Minnesota to help alleviate the stress that invasive plants put on the ecosystem, but continued use of herbicides has its own environmental downside. An analysis of five common aquatic herbicides including, diquat, endothall, 2,4-D, fluridone, and copper-based solutions was completed to find specific ecological downsides. Sediment degradation, effects on various fish life stages, zooplankton, and other non-target organisms were analyzed. This study offers alternative managements strategies and presents a decision tree to help lake associations manage invasive plants.
