Infected tree removed

According to a CDFA statement, a CDFA crew removed and disposed of the infected tree and will conduct treatment of citrus trees for any Asian citrus psyllid (ACP) infestation within 800 meters of the find site.

The ACP pest is the primary vector of HLB.

“By taking these steps, a critical reservoir of disease and its vectors will be removed which is essential,” Secretary Ross said. 

CDFA reports an intensive survey of local citrus trees and psyllids is underway to determine if HLB exists anywhere else in the San Gabriel area.

Rapid quarantine expected

Planning has begun for an area quarantine to limit the spread of the disease by restricting the movement of citrus trees, citrus plant parts, green waste, and all citrus fruit except commercially cleaned- and packed-citrus.

As part of the quarantine, citrus and closely related plants at nurseries in the area will be placed on hold.

Currently, ACP quarantines are in place in 17 California counties.

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 onsite. 

Secretary Ross added, “We have been planning and preparing for HLB detections with our growers and our colleagues at the federal and local levels since before the Asian citrus psyllid was first detected here in 2008.”
