Detection of HLB in VC establishes new quarantine area
October 3, 2023

CDFA has declared a quarantine in Ventura County following the detection of the citrus disease Huanglongbing (HLB), or citrus greening, in two citrus trees on one residential property in the city of Santa Paula. These detections are the first HLB-positive trees in Ventura County. CDFA is working with the USDA and the Ventura County Agricultural Commissioner on this cooperative project.

The detection will require a mandatory five-mile-radius quarantine area around the find site to restrict the movement of citrus fruit, trees, and related plant material. The quarantine area is bordered on the north by Ojai Road; on the south by E Los Angeles Avenue; on the west by Wells Road; and on the east by Balcom Canyon Road. HLB quarantine maps for Ventura County are available online at:
