Abstract

In July and August 2013, blossom blight and soft rot of pods were observed on okra in experimental fields in Iksan and Jeju, Korea. Infection started in fading flower petals, spread to entire flowers and young pods, resulting in blighted blossoms and soft rot of pods. Severe infection caused early falling of blossoms and fruit drop, reducing plant vigour in the summer season. On the basis of the morphological characteristics and phylogenetic analyses of two molecular markers ITS rDNA and D1/D2 region of the LSU, the fungus was identified as Choanephora cucurbitarum. A pathogenicity test was carried out to fulfil Koch's postulates. To our knowledge, this is the first report of C. cucurbitarum on okra in Korea.
