Citrus Quarantine Program (CQP)
The department’s Citrus Quarantine Program (CQP) supports and promotes the local citrus industry by enforcing Asian Citrus Psyllid (ACP) and Huanglongbing (HLB) quarantine regulations. Inspections conducted by CQP inspectors ensure compliance in order to suppress the movement of ACP and therefore mitigate the potential spread of HLB into the region.

First CLas-positive Asian citrus psyllid found in San Diego County – 12/31/2020
An Asian citrus psyllid (ACP) sample – confirmed positive for Candidatus Liberibacter asiaticus (CLas), the bacteria that causes Huanglongbing (HLB) – was collected from a residential property in the Fallbrook area of San Diego County. While the first confirmation of a CLas-positive ACP in San Diego County is concerning, as of today, HLB has not been detected in any San Diego County trees but surveying and sampling of area trees is ongoing.

New Special Permit Quarantine Commodity 1543 for Bulk Citrus Movement from Adjacent ACP Quarantine Zone into HLB Quarantine Area
Effective July 31, 2020, bulk citrus fruit may be shipped directly to a packinghouse or processor located within a Huanglongbing (HLB) quarantine area without meeting the ACP-free performance standard, provided that the shipment originates from the immediately adjacent, surrounding Asian citrus psyllid (ACP) bulk citrus regional quarantine zone. All shipments of citrus fruit must continue to be fully safeguarded with a tarp or enclosed vehicle while in transit. For more information, click here.
As of January 8, 2021, a total of 2,243 trees and 325 ACP samples have tested positive for the HLB bacterium on a total of 1,637 sites. The sites are located in the following counties: San Diego, Los Angeles, Orange, Riverside, and San Bernardino.

California Citrus Pest and Disease Prevention Committee (CPDPC)
endorses “Best Practices for Growers in Response to HLB in California.”
To provide California citrus growers with a strong toolbox of
options to protect their orchards from Huanglongbing (HLB), the Citrus
Pest & Disease Prevention Committee has endorsed the following
“Best Practices for Growers in Response to HLB in California.” The
recommendations – which are grouped based on a grower’s proximity to
an HLB detection – represent the most effective tools known to the
citrus industry at this time and are meant to supplement the
California Department of Food and Agriculture’s required regulatory
Growers are encouraged to use as many methods as feasible for their operation in order to limit the spread of the Asian citrus psyllid (ACP) and HLB, as the cost to manage the Asian citrus psyllid is far less than any potential costs or loss to the industry should HLB take hold throughout our state.
