Your Local Grower Liaison: On the Frontline in the Fight Against HLB


The battle to save California citrus from the Asian citrus psyllid and Huanglongbing (HLB) is a collaborative effort that involves local, county, state and federal officials, researchers, scientists and commercial citrus growers. To help facilitate pest management and disease eradication, the Citrus Pest & Disease Prevention Program (CPDPP) has identified a program manager and key individuals in each region to be a growers’ main point of contact for information and updates on activities occurring in their region.

Grower Liaisons are CPDPP’s boots-on-the-ground leaders in the fight against ACP and HLB and growers across the state are encouraged to interact regularly with their region’s representative. Learn more about your grower liaison below and request to be added to their email updates for timely updates impacting your area!
