Topics include updates on ACP/ HLB treatments & research, regulatory updates on HLB and other citrus pests, and an update from the new County Ag Commissioner, Jose Chang.

Asian Citrus Psyllid Update
The next ACP Area Wide Management treatment window for growers will be September 3 - 23. In the meantime, please continue to regularly monitor new flush for signs of the psyllid, and consult with your pest management professional if ACP is present. Tender new citrus flush is ideal habitat for ACP to feed, lay eggs and build new populations, and an increase in ACP numbers and feeding can increase the risk of HLB. If your citrus is no longer being cared for or is not worth the resources required to protect it from ACP and HLB, consider removing it.
HLB Quarantine Update
As of May 26, a total of 5.115 trees and 709 ACP have been confirmed positive for the bacterium that causes HLB. Trees confirmed positive are treated for ACP and removed, and the HLB quarantine may be expanded. Additional ACP treatments and HLB detection surveys are conducted on a recurring basis to remaining citrus within 250 meters of each detection.
Counties where HLB has been detected via PCR testing are Los Angeles, Orange, San Diego, Riverside, San Bernardino and San Diego, with the majority of detections in Orange County. To see a map of the current HLB quarantine areas, and other details of locations and numbers of HLB detections, please visit maps.cdfa.ca.gov/WeeklyACPMaps/HLBWeb/HLB_Treatments.pdf.
HLB Detection Response Guide for Growers
To ensure California citrus growers are well prepared in the event of a potential commercial grove detection of Huanglongbing (HLB), the Citrus Pest and Disease Prevention Program (CPDPP) has developed the Response Guide for a Confirmed HLB Positive Detection in a Commercial Grove, which details the steps taken by CDFA and actions required of the property or grove owner, as outlined in CDFA's Action Plan and Information for Citrus Growers/Grove Managers.
