摘要： Okra (Abelmoschus esculentus) is an economically important plant in China which is widely used in food, medicine and manufacturing. In September 2014, diseased samples of okra were collected in Yanqing District, Beijing City, China. Symptoms were brown to brownish black, sunken cavities on the leaves and fruits. The disease occurred on okra plants with an incidence of 35-55% in different fields. According to morphological and cultural characteristics, and sequence analysis of the internal transcribed spacer (ITS) and actin (ACT) regions, the pathogen was identified as Boeremia exigua (Desm.) Aveskamp, Gruyter & Verkley. Pathogenicity of the isolated fungus was conducted on okra fruits and on potted plants. Symptoms similar to those occurring in the field were reproduced. This is the first report of Boeremia spot of okra caused by Boeremia exigua in China.
