SANTA BARBARA COUNTY CITRUS UPDATES
ACP Update
The next Area Wide Management coordinated grower treatment window will be in January. Be sure to renew permits as needed with the County Agriculture Department. Growers are also encouraged to work with your pest management professionals to stay vigilant with regular monitoring of your trees for ACP, especially young trees and along grove perimeters. Research shows that in generally infested areas like Santa Barbara County, keeping ACP populations low reduces the risk of citrus trees acquiring the bacteria that causes the deadly HLB disease.
Please consider removing citrus that is no longer being cared for or is not worth the resources required to protect it from ACP & HLB.
Biological Control Releases
Monthly releases of the ACP biological control agent Tamarixia radiata continued in October in residential areas of Santa Maria, Guadalupe, and Orcutt in the northern part of the county, and to the south in Goleta, Santa Barbara, Montecito, Summerland and Carpinteria.

HLB Quarantine Update
As of October 28, a total of 3,942 trees and 501 ACP have tested positive via PCR for the bacterium that causes HLB. Trees that test 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. Recent expansions of the HLB quarantine occurred in Riverside and Orange counties. 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.
To help you prepare for the regulatory impacts of HLB, please refer to CDFA's Information for Citrus Growers/Grove Managers, Action Plan for ACP and HLB or this summary flier for information on regulatory and treatment requirements growers can expect when HLB is detected in or near your citrus grove or packing house.
