March 3, 2026 (Ramona) -- The California Department of Food and Agriculture on Monday declared a new citrus quarantine in Ramona after two citrus trees in a residential area tested positive for Huanglongbing, also known as citrus greening.
 
The detections were made during routine inspections, according to officials with the County of San Diego.
 
HLB is one of the most destructive citrus diseases in the world. The bacterial disease causes bitter, misshapen fruit unsuitable for sale or eating and eventually kills infected trees. Symptoms can include mottled yellow leaves that often appear in asymmetrical patterns.
