Sudden Oak Death Becomes a Concern

Posted By Jim Calkins, Tuesday, June 18, 2019

Rhododendrons infected with sudden oak death were shipped to Indiana (and nine other, unnamed states) according to an article published in Nursery Management (https://www.nurserymag.com/article/sudden-oak-death-worse-than-thought-indiana/). Janna Beckerman from Purdue University Extension has also posted a Special Alert on the topic at https://www.purduelandscapereport.org/article/special-alert-sudden-oak-death/.

Sudden oak death (SOD), caused by a fungus (Phytophthora ramorum), is a serious disease and is regulated by USDA APHIS PPQ. SOD is not believed to be native to North America and has only been documented as being established in western California, one county in southwestern Oregon, and possibly in British Columbia in Canada. It has also been documented in several locations in Europe. Although the disease kills oaks (including at least some of our native species), more than 100 other species not related to oaks, including a number of important nursery and landscape species (woody and herbaceous), have been identified as hosts/potential carriers.
