Pest Detected in San Luis Obispo

The following press release was issued by the San Luis Obispo County Agricultural Commissioner’s office on Aug. 5, 2014. Additional details regarding potential regulatory implications for industry members will come soon.

San Luis Obispo, CA — The detection of an adult Asian Citrus Psyllid (ACP) in an insect trap in a residential neighborhood in northeast San Luis Obispo has prompted a high density trapping delimitation survey of the surrounding area. A quarantine restricting the movement of citrus nursery stock and citrus fruit will be established by the California Department of Food and Agriculture to prevent the spread of this serious plant pest. Control efforts will take place in the near future in the area immediately surrounding the detection.

This is the second detection of ACP in San Luis Obispo County. The first detection occurred this past March in Arroyo Grande; only a single ACP was detected. Intensive trapping and visual surveys are ongoing, but no additional insects have been detected. However, a quarantine restricting the movement of citrus nursery stock and citrus fruit remains in effect in a five-mile radius surrounding the Arroyo Grande detection site.

Multi-Cultural Outreach in San Francisco

The Citrus Pest & Disease Prevention Program and U.S. Customs and Border Protection recently collaborated on a press conference to raise awareness of the dangers of bringing citrus fruit and plant material into the country from other areas. The backdrop for the event was the San Francisco International Airport, a hub of global travel in a multi-cultural city where many residents enjoy fresh, homegrown citrus fruit.

Broadcast and print reporters set up at a baggage carousel in San Francisco International Airport to hear from Citrus Pest & Disease Prevention Program and Customs and Border Protection on the dangers of transporting citrus plant material.

Psyllid Management Areas in Tulare County

Developed by the top minds at University of California, California Citrus Mutual and Citrus Research Board, along with other industry leaders, a new area-wide treatment strategy is being introduced to citrus growers to organize the industry and allow for rapid communication if area-wide insecticide treatments are needed.

Coordinated treatments are the most effective way to manage the Asian citrus psyllid and thereby protect our state’s citrus from the incurable Huanglongbing disease, and this new strategy lays the framework for how neighboring growers should synchronize treatments to have the maximum impact on this pest. Right now, Tulare County is still in eradication mode, but the industry should plan for what may come next.

San Diego County Update from Grower Liaison Enrico Ferro

It has been a busy month for the San Diego County Asian Citrus Psyllid Task Force. We held three meetings to get growers thinking about their fall systemic coordinated treatments, and there were additional finds in the Rancho Santa Fe area – an area that has not had any finds in quite a while.

The meetings were held in Valley Center, Fallbrook and Pauma Valley and were well attended. As a new liaison in the area, the meetings not only helped open up the line of communication between me and the local industry, but they also served as a tool to keep growers informed about the Asian citrus psyllid and how to detect and manage a find. In fact, a grower recently contacted me to say that he could now find the psyllid after attending the meeting.

There are still many growers and homeowners with citrus who are unaware of ACP and HLB. I am now being contacted by people who are just learning about this problem and I will be visiting properties throughout July to make contact with the owners and bring them up to date. This includes properties with abandoned trees, new growers and homeowners with 10-25 trees.
