Multiple discoveries of the Asian citrus psyllid — a pest that can spread a deadly and incurable plant disease called Huanglongbing — have prompted state agriculture officials to place a quarantine in portions of Santa Clara and Alameda counties. Residents are instructed to not move citrus fruit or plants from their property to other parts of the Bay Area or California because they could unknowingly spread this harmful insect and disease. You can view the quarantine area at: http://pi.cdfa.ca.gov/pqm/manual/pdf/maps/ 3435ACPSantaClaraAlameda.pdf. Fremont, Milpitas and San Jose are among the cities in the quarantine area.
Huanglongbing is not harmful to humans or animals but is fatal for citrus trees and there is no cure. While researchers are pouring resources into finding a cure, the best way to protect local citrus trees now is by keeping the Asian citrus psyllid out of the area, and not transporting citrus fruit or plants is key.
