Sudden Oak Death

In early June 2019, KDA confirmed the presence of Sudden Oak Death (SOD) in Kansas. SOD is a plant disease that has killed large tracts of oaks and other native species in California and Oregon, and infected rhododendrons have been identified in 10 states in the Midwest, including Kansas. The infected plants that have been found in the Midwest have all been traced back to a common source.
