More California Citrus Placed Under Psyllid Quarantine
March 27, 2015 An additional portion of Madera County has been placed under quarantine for the Asian citrus psyllid (ACP) following the detection of one psyllid east of the City of Madera, in the Bonadelle Ranchos-Madera Ranchos area.
The quarantine expansion adds 79 square miles, bringing the total quarantine area in Madera County to 179 square miles. The 79 square mile expansion is bordered on the north by Avenue 15; on the south by Avenue 9; on the west by Main Canal; and on the east by State Highway 41.
The quarantine prohibits the movement of citrus and curry tree nursery stock out of the quarantine area and requires that all citrus fruit be cleaned of leaves and stems prior to moving out of the quarantine area. An exception may be made for nursery stock and budwood grown in USDA-approved structures that are designed to keep ACP and other insects out.
Residents with backyard citrus trees in the quarantine area are asked not to transport citrus fruit or leaves, potted citrus trees, or curry leaves from the quarantine area.
In addition to a portion of Madera County, ACP county-wide quarantines are now in place in Imperial, Los Angeles, Orange, Riverside, San Bernardino, San Diego, Santa Barbara, Tulare, and Ventura counties, with portions of Fresno, Kern, San Joaquin, San Luis Obispo, and Santa Clara counties also under quarantine.
The ACP is an invasive species of grave concern because it can carry the disease huanglongbing (HLB), also known as citrus greening. All citrus and closely related species, such as curry trees, are susceptible hosts for both the insect and disease.
There is no cure once a tree becomes infected, the diseased tree will decline in health and produce bitter, misshaped fruit until it dies. HLB has been detected just once in California – in 2012 on a single residential property in Hacienda Heights, Los Angeles County. This plant disease does not affect human health.
Residents in the area who think they may have seen ACP or symptoms of HLB on their citrus trees are urged to call CDFA’s Pest Hotline at 1-800-491-1899. For more information on the ACP and HLB, please visit the website established by the California Department of Food and Agriculture.
