The report came from a grove in the Woodcrest area of Riverside County. CDFA staff have been taking samples and conducting surveys across the perimeter of the site. Growers within a 250-meter radius are being encouraged to apply insecticides to stop the psyllid. The area is under quarantine to prevent the spread of the pest and disease.
