A portion of Placer County has been placed under quarantine for Asian citrus psyllid (ACP) following the detection of multiple life stages on citrus trees within the City of Lincoln.
The quarantine zone in Placer County measures 118 square miles, bordered on the north by Riosa Road; on the south by the Roseville City Limit; on the west by Brewer Road; and on the east by Fowler Road. The quarantine map for Placer County is available online at: https://www.cdfa.ca.gov/plant/acp/regulation.html#maps. Please check this link for future quarantine expansions in this county, should they occur. Quarantines in new counties will be announced separately.
This is a case where an individual moved infested trees from a quarantine zone into a clean county and ended up moving psyllid with the trees. This is how so many of our current pests are moving around - Shot Hole Borer, 1000 Cankers of Walnut, Emerald Borer, Gold Spotted Borer. On and on, we are the culprits of our own destruction. Pretty soon every pest known to plants will be everywhere. Sorry for the rant.
