Abstract

First report of leaf spot of Phlox paniculata caused by Septoria phlogis in Korea.

Abstract

Leaf spot was observed on garden phlox (Phlox paniculata) in Yesan, Korea, in 2008. Based on the morphological characteristics of the fungus and the host genus, the isolate was identified as Septoria phlogis. Internal transcribed spacer sequences of rDNA of the isolate confirmed its close affinity to previously known species of Septoria. In 2010 and 2011, the disease was observed in Hoengseong, Korea. This is the first report of Septoria leaf spot on garden phlox in Korea.
