Description

Diagnosis of sudden oak death (SOD) in tanoak (Notholithocarpus densiflorus (Hook. & Arn.) Manos, Cannon & S.H. Oh) and susceptible red/black oak species (coast live oak, Quercus agrifolia Née; Shreve oak, Q. parvula Greene var. shrevei (C.H. Mull.) Nixon; California black oak, Q. kelloggii Newb.) is facilitated by the fact that infected trees commonly develop obvious bleeding bark cankers. In contrast, canyon live oak (Q. chrysolepis Liebm.) exhibits a different pattern of symptom expression, which has made it difficult to identify and document Phytophthora ramorum bole cankers in this species.
