Asian Citrus Psyllid Quarantine Established in San Luis Obispo County
April 3, 2014
Breaking News: NEW ACP Discovery
Victoria Hornbaker, APHIS Citrus Program Manager, announced TODAY the first confirmed Asian citrus psyllid find in San Luis Obispo County as reported in a San Luis Obispo County Ag Commissioner’s press release.
Hornbaker also announced a Science Advisory Panel Report Stakeholder meeting will be held on April 16, 2014 at 9 am at CDFA headquarters, 1220 N Street, Room 220, Sacramento, CA 95814. To participate via conference call, please call 866-692-3158 and use participant code 87947483.
The meeting agenda follows this article.
Martin Settevendemie, Agricultural Commissioner/Sealer, County of San Luis Obispo announced detection of an adult Asian Citrus Psyllid in an insect trap on March 26th in a residential landscape near Arroyo Grande. The discovery prompted a high-density trapping delimitation survey of the immediate and adjacent area - about a nine square mile area - and no other ACPs were found.
A quarantine restricting the movement of citrus nursery stock and citrus fruit within a five-mile radius around the detection site has already been established by the California Department of Food and Agriculture to prevent the spread of this serious plant pest. “We are working with growers to get everyone in compliance with the regulation. This will help them understand what the requirements are to move any product outside of the quarantine area,” said Settevendemie.
CDFA announced that they will be conducting spray eradication treatments approximately 800 meters around the detection to eradicate this pest.
The first detection of the Asian Citrus Psyllid in California occurred in San Diego County in 2008. Since then, it has been found throughout southern California.
“This insect pest is of serious concern to California’s commercial citrus because it is responsible for spreading Huanglongbing, also called citrus greening disease, a plant disease that is fatal to all types of citrus trees. This includes citrus trees in countless landscapes across the county as well as local commercial citrus orchards valued at over $13 million in 2013,” according to Settevendemie.
Over the past ten years nearly 50% of the commercial citrus groves in Florida have been killed by this disease. 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 for the state. The disease does not affect human health.
A single orange tree infected with Huanglongbing was found in a Los Angeles County backyard in 2012. To date no additional detections of the disease in California have occurred.
Staff from the San Luis Obispo County Agricultural Commissioner’s office and officials from the California Department of Food and Agriculture continue to search for this pest by monitoring hundreds of insect traps placed in urban neighborhoods and commercial orchards throughout the county.
“It is difficult to close off all potential pest pathways into the county. An engaged community of all county residents is critical in successfully excluding pests such as Asian Citrus Psyllid,” said Settevendemie.
Community members can do the following to protect backyard citrus trees and the local citrus industry:
Buy Local! Purchase citrus trees from reputable local sources selling plants that have been routinely inspected by the Agricultural Commissioner’s staff.
Do not transport citrus plants or plant parts into the county from quarantine areas. Call 805- 781-5910 for information about quarantine areas.
Check residential landscaping often for signs of unusual symptoms or strange insects. Contact the local University of California Cooperative Extension’s Master Gardener Program at 805-781-5939 for help in identification of unusual plant symptoms or pests.
If asked, allow the Agricultural Commissioner’s staff to place an insect trap in your yard and cooperate with officials if it becomes necessary to exclude or eliminate Asian Citrus Psyllid from San Luis Obispo County.
