Abstract
AbstractOkra (Abelmoschus esculentus), or Lady's finger, is a plant originating from Africa and is grown as a multipurpose crop in Asia, America and Europe nowadays. Grey mould disease was observed on okras in several okra fields in Ledong County, Hainan Province, and Shunyi District, Beijing City, during September to December in 2014 with the incidence varying from 20 to 55%. To identify the pathogen, the detailed morphological, cultural characteristics, pathogenicity test along with the DNA sequences for four gene regions ITS, G3PDH, HSP60 and RPB2 of our isolate were compared with those of some previously reported Botrytis cinerea and other similar species of the genus Botrytis. Results suggested this is the first report of grey mould disease on Abelmoschus esculentus caused by Botrytis cinerea in China.
