Citrus Pest and Disease Prevention Division

About Us

The Citrus Pest and Disease Prevention Division (CPDPD) was established in 2019 to protect California from damage caused by the introduction or spread of harmful citrus pests and diseases. The CPDPD provides leadership over pest prevention and management programs that protect the state’s agriculture and natural resources from invasive citrus pests and diseases.

The CPDPD conducts a statewide detection trapping program, detection surveys, pest and disease control programs, implements environmental monitoring practices, and engages in outreach and educational programs. The CPDPD consults with the California Primary State Scientists, United States Department of Agriculture (USDA), global subject matter experts, State regulatory agencies, County Agricultural Commissioners, citrus industry, and academia to continuously improve the Division's components.

The CPDPD enforces quarantine regulations to prevent the artificial spread of invasive pests within the state. The CPDPD works closely with the citrus industry to facilitate business operations while protecting California’s agriculture.

The CPDPD operates out of 12 field offices strategically located in areas near pest and disease infestations and in proximity to commercial citrus. The state is divided into three geographical districts (Northern, Central, and Southern) with each district lead by a District Manager. Each district works under the direction of the Branch Chief and Division Director located at the Sacramento headquarters office. The Northern District is responsible for activities in Alameda, Alpine, Amador, Butte, Calaveras, Colusa, Contra Costa, Del Norte, El Dorado, Glenn, Humboldt, Lake, Lassen, Marin, Mendocino, Modoc, Napa, Nevada, Placer, Plumas, Sacramento, San Francisco, San Joaquin, San Mateo, Santa Clara, Santa Cruz, Shasta, Sierra, Siskiyou, Solano, Sonoma, Sutter, Stanislaus, Tehama, Tuolumne, Trinity, Yolo, and Yuba Counties. The Central District covers the counties of Fresno, Inyo, Kern, Kings, Madera, Mariposa, Merced, Mono, Monterey, San Benito, San Luis Obispo, Santa Barbara, Tulare, and Ventura Counties. The Southern District is responsible for Imperial, Los Angeles, Orange, Riverside, San Bernardino, and San Diego Counties.

In addition to the field activities, the CPDPD, includes the Data Analysis and Visualization Unit (DAVU) and an Administration Unit. The DAVU analyzes detection data for citrus pests and diseases to generate products for our various stakeholders. These work products include maps for survey, treatment, and regulatory activities. The DAVU also coordinates with the USDA to design the statewide HLB risk-based survey program. The Administration Unit supports the field offices by conducting procurement, fiscal management and human resources activities.
