Hygrophila polysperma can become an invasive problem in some tropical and temperate regions outside of its native range. In this study, I evaluated the prospects for classical biological control of this invasive weed.

Hygrophila polysperma interferes with navigation and has been known to compete with other aggressive non-native invasive plants. It has also been reported in Northern Mexico. East Indian hygrophila (Hygrophila polysperma) has replaced hydrilla (Hydrilla verticillata) as the major aquatic weed in some parts of Florida, and is considered by the state's Exotic Pest Plant Council to be one of the most invasive non-indigenous aquatic plants in this part of the USA.
