Sudden Death of Oaks

Enrico Bonello, urban plant pathologist for Ohio State University, updated the group on the status of Sudden Oak Death Syndrome, a relatively new disease problem that is quite serious on tanoak and true oaks in California, caused by the fungus Phytophthora ramorum.

This fungus has been identified on rhododendrons from Germany and also now confirmed on oaks in Oregon, and is listed as a host of a number of plants, including California buckeye and other oaks including red oak and pin oak.

It causes large trunk cankers, is quite devastating, and has received a great deal of attention from the U.S. Department of Agriculture, which has approved $24 million in funding, including $19 million for research. Thankfully, it is not yet reported from the eastern United States.
