Sudden Oak Death
The plant disease known as sudden oak death (SOD) first appeared in California in 1995. This disease is caused by a fungus-like pathogen Phytophthora ramorum and attacks at least 37 different plants species, including numerous kinds of trees and shrubs, and container grown nursery crops. Since 1995 SOD has been found in Oregon, Washington, and British Columbia.
In mid-March 2004, USDA notified the PA Department of Agriculture (PDA) that camellias potentially infected with the SOD pathogen might have been shipped to many Eastern U.S. states (including PA) from Monrovia, a large wholesale nursery stock producer in Azusa, CA. PDA plant inspectors are currently visiting PA sites that might have received shipments from Monrovia. Suspect plants will be placed under "stop-sale." Any symptomatic plants will be inspected and sampled for analysis at the Plant Disease Diagnostic Laboratory, PDA.
