Control Measures for Alligatorweed in Southeastern States

Alligatorweed, a flowering plant originally reported in Alabama in 1897, thrives in diverse habitats across the southeastern U.S. Characterized by its small, one-seeded fruits and distinct leaves that can be opposite and narrowly elliptic or spatulate, this invasive species can cause significant ecological disruption. To manage its spread, biological control measures such as the introduction of the alligator flea beetle (Agasicles hygrophila) were established in 1965. Understanding its characteristics and control methods is essential to mitigate its impact in aquatic environments.
