Two additional huanglongbing-positive trees have been confirmed in a residential backyard in the San Gabriel region of Los Angeles County. The finds, which bring the total number of HLB-positive trees in California to 30, were found on a property that had infected trees previously confirmed and removed. At this time, the California Department of Food and Agriculture is working with the property owner to have the trees removed. The finds are a result of ongoing intensive HLB surveys being done in the area.

Two more trees have been confirmed positive for Huanglongbing (HLB), the plant disease carried by an invasive insect called the Asian citrus psyllid (ACP).
One tree is located in San Gabriel and the other is in Hacienda Heights, in very close proximity to the original HLB find from 2012. As always, the California Department of Food and Agriculture worked quickly to contact the homeowners and remove the infected trees. The tree in San Gabriel has already been removed, and the tree in Hacienda Heights is scheduled to be removed today.
The Citrus Pest & Disease Prevention Program outreach team has been active with HLB education in Los Angeles for many months....
