The San Joaquin County Agricultural Commissioner, in cooperation with the California Department of Food and Agriculture and the United States Department of Agriculture, is beginning an extensive survey in response to the detection of one additional Asian Citrus Psyllid (ACP) within the boundaries of the City of Tracy.
The ACP was positively identified on June 28  around South Cabe Road and West 11th Street within the City of Tracy. In response to the detection, an increased number of traps will be deployed and a visual survey initiated in the surrounding properties in an attempt to determine if there is an infestation. There will be an expansion of the existing Tracy quarantine making a continual quarantine area from Manteca west to the Alameda County line.
“The Asian Citrus Psyllid is a dangerous pest of citrus,” said Tim Pelican, San Joaquin County Agricultural Commissioner. “We are working to determine the full extent of this infestation so that we can protect our State’s vital citrus industry as well as our backyard citrus trees. Working together we can prevent the spread of this invasive species and the harm it can cause.”
All citrus and closely related species are susceptible hosts for both the insect and the 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. The citrus is safe to eat and the disease is not harmful to human health.
If you think you may have the pest do not remove it or any plant materials from the area. Residents in the area who think they may have seen the pest are urged to call the Pest Hotline at 1-800-491-1899. For more information on the Asian Citrus Psyllid and Huanglongbing disease, visit:
