FPL | Hydrilla


Origin: Sri Lanka, southern India and Korea

Impacts: Hydrilla is described as the most serious aquatic weed problem in the state of Florida.

It can grow up to one inch per day. It is resistant to many control techniques, making it extremely difficult to manage.

It is an aggressive and competitive plant that displaces beneficial native vegetation that provide food for prey species, thereby reducing weights and sizes of sportfish.

The state of Florida spends approximately $14.5 million each year on hydrilla control.
