Citrus Greening Found For First Time In California

Florida Citrus Show Extended Content Coverage: On A Mission

The California Department of Food and Agriculture (CDFA) and the USDA announced they had found the state’s first detection of the citrus disease known as Huanglongbing (HLB), or citrus greening. The disease was detected in an Asian citrus psyllid sample and plant material taken from a lemon/pummelo tree in a residential neighborhood in the Hacienda Heights area of Los Angeles County.

HLB is a bacterial disease that attacks the vascular system of plants. The Asian citrus psyllid can spread the bacteria as the pest feeds on citrus trees and other plants. Once a tree is infected, there is no cure; it typically declines and dies within a few years.

“Citrus is not just a part of California’s agricultural economy; it’s a cherished part of our landscape and our shared history,” said CDFASecretary Karen Ross. “CDFA is moving swiftly to protect the state’s citrus growers as well as our residential trees and the many prized citrus plantings in our parks and other public lands. We have been planning and preparing for this scenario with our growers and our colleagues at the federal and local levels since before the Asian citrus psyllid was first detected here in 2008.”

In fact, just three weeks ago CDFA’s acting director for Plant Health and Pest Prevention Services, Robert Leavitt, announced at the annual meeting of California Citrus Mutual (CCM) that the state was instituting a policy of zero tolerance regarding HLB. Any infected tree would be removed and the area sprayed with pesticides if HLB was found in any citrus tree, whether in a commercial grove or residential setting. “CDFA is committed to working with the industry to fight HLB tree by tree, state by state, and grove by grove,” Leavitt told the many growers and others affiliated with the  industry at the CCM meeting.

CDFA officials are making arrangements to remove and dispose of the infected tree found in LA and conduct treatment of citrus trees within 800 meters of the find site. By taking these steps, a critical reservoir of disease and its vectors will be removed, which officials say is essential. Treatment for HLB will be conducted with the oversight of the California Environmental Protection Agency (Cal-EPA). Officials emphasized the treatment will be conducted safely, with advance and follow-up notices provided to residents in the treatment area.

An intensive survey of local citrus trees and psyllids is under way to determine the source and extent of the HLB infestation. Planning has begun for a quarantine of the infested area to limit the spread of the disease by restricting the movement of citrus trees, citrus plant parts, green waste, and all citrus fruit except what is commercially cleaned and packed. As part of the quarantine, citrus and closely related plants at nurseries in the area will be placed on hold.

Residents of quarantine areas are urged not to remove or share citrus fruit, trees, clippings/grafts or related plant material. Citrus fruit may be harvested and consumed on-site.

CDFA, in partnership with the USDA, local agricultural commissioners and the citrus industry, continues to pursue a strategy of controlling the spread of Asian citrus psyllids while researchers work to find a cure for the disease.

HLB is known to be present in Mexico and in parts of the southern U.S. Florida first detected the pest in 1998 and the disease in 2005, and the two have now been detected in all 30 citrus-producing counties in that state. The University of Florida estimates the disease has tallied more than 6,600 lost jobs, $1.3 billion in lost revenue to growers and $3.6 billion in lost economic activity. The pest and the disease are also present in Texas, Louisiana, Georgia and South Carolina. The states of Arizona, Mississippi and Alabama have detected the pest but not the disease.

The Asian citrus psyllid was first detected in California in 2008, and quarantines are now in place in Ventura, San Diego, Imperial, Orange, Los Angeles, Santa Barbara, San Bernardino and Riverside counties. CCM officials say it is vital to keep the psyllid – and the deadly HLB it spreads – out of the San Joaquin Valley, the home of the state’s famed “Citrus Belt.” If Californians believe they have seen evidence of HLB in local citrus trees, they are asked to please call CDFA’s toll-free pest hotline at 1-800-491-1899.
