The detection of Asian Citrus Psyllid in in the Arroyo Grande area of San Luis Obispo County has triggered the California Department of Food and Agriculture (CDFA) to issue a quarantine for the southern portion of the county. As reported in Spotlight last week, one psyllid was detected in the county and marks the ever-increasing spread of psyllid detections emanating from San Diego, north to a host of other counties, including Imperial, Los Angeles, Riverside, San Bernadino, San Diego, Santa Barbara, Ventura, as well as portions of Fresno, Kern and Tulare Counties.
