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....
