Citrus Quarantine Program (CQP)

Asian Citrus Psyllid

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.

NEW HLB Find in Tijuana, Mexico

    An ACP (Asian Citrus Psyllid) on the outskirts of Tijuana tested positive for Clas, the bacteria that leads to Citrus Greening (a.k.a. HLB). The infected psyllid was found seven miles south of the US-Mexico border. This is the first time an HLB positive psyllid has been found in the area since the United States Department of Agriculture (USDA) began its cooperative program with Mexico. The USDA works cooperatively with Mexico to conduct area wide treatments, biocontrol and surveys in the border region to help prevent the spread of HLB. The find site is currently being treated and surrounding trees and ACP are being tested for HLB. Updates to follow as more info becomes available. 

    As of February March 10, 2020, a total of 1,847 trees and 293 ACP samples have tested positive for the HLB bacterium on a total of 1,310 sites. The sites are located in the following counties: 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 response.

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.
