In 2015, a new leaf spot disease was observed on strawberry seedlings in Wanju, Korea. Tanned
brown spots appeared on the leaves of the infected plants, and often coalesced to form larger
necrotic areas, resulting in the death of foliage. An isolate was obtained in pure culture. On the
basis of morphological characteristics and molecular analysis of internal transcribed spacer rDNA
sequence, the causal agent was identified as . Pathogenicity tests revealed the
isolate was pathogenic to the leaves and fruits of strawberry. To the best of our knowledge, this is
the first report of P. concavum causing tan-brown leaf spot on strawberry in Korea.
