Hydrilla Program - CDFA Updated:11/2022

The Program is a statewide effort to detect the highly invasive weed hydrilla and mitigate its spread by quarantine and eradication methods. The goal of the Program is to eradicate all existing infestations of hydrilla within the State and prevent any new infestations from establishing in the future. This is achieved through: 1) prevention via education; 2) detection via surveys and outreach; and 3) eradication.

The California Department of Food and Agriculture (CDFA) conducts eradication efforts in multiple counties throughout California integrating various methods of control and management. The largest eradication effort is the infestation in Clear Lake which began in 1994. The Program has successfully eradicated hydrilla from 15 counties.
