HLB Update
In San Bernardino County a single residential tree tested positive for the bacterium that causes HLB. As a result, the HLB quarantine has been expanded in the Montclair area. Also of note is an adult ACP that recently tested positive for the bacterium that causes HLB near Corona, outside of the HLB quarantine. See the latest HLB map for details: maps.cdfa.ca.gov/WeeklyACPMaps/HLBWeb/HLB_Treatments.pdf. As before, all HLB detections to date have been on residential properties, the infected trees have been or are being removed, and ACP treatments are applied on a recurring basis to remaining citrus in those areas. No HLB has been found in commercial groves via PCR testing.
Regulatory responses required by the state in response to an HLB detection are described in CDFA's Action Plan for ACP and HLB.
How Close Is HLB To Your Citrus? There's a New UC App For That!
Visit ucanr.edu/hlbgrowerapp , zoom to or type in your location and it shows your proximity to HLB+ detections, recommends best practices to protect your citrus from HLB based on your current proximity to know detections, and provides a link to the Voluntary Grower Response Plan for more information. As HLB detections via PCR increase and spread, it's important to be aware of possible actions you could take to further protect your citrus should an HLB detection occur in your area.
CITRUS REMOVAL PROGRAM: Citrus trees that are neglected or abandoned may harbor ACP and HLB, increasing risk to other citrus in the area. Abandoned and neglected trees may be reported to me or the county Ag Commissioner's office. The Citrus Matters ACT NOW program may be able to assist in citrus removal.
