ABSTRACT
The article highlights sudden oak death, Phytophthora ramorum or Phytophthora canker disease, a fungus first identified on 1993 in Germany and in Netherlands on ornamental rhododendrons. According to the author, the name sudden oak death is used because of the rapid color change of leaves from green to brown. He added that fungus causes a bleeding canker on the stem of certain hosts, staining the surface of the bark and the lichens that grow on it. Moreover, the Phytophthora ramorum causes two types of diseases such as bark cankers that may kill the host and foliar blights that may serve as a reservoir for the pathogen. He emphasized that the sudden oak death has occurred primarily in California and southwestern Oregon.
