摘要： Wild eggplant (Solanum torvum) has been used as a rootstock for eggplant propagation in China for decades. In the winter of 2011-2012, a severe disease with typical symptoms of small brown spots was observed on the leaves of wild eggplant in Chengmai County, Hainan Province, China. This disease had an incidence of about 30-65% among all the plants in the region (about 2 hectares in total). The causal pathogen was identified as Stemphylium solani based on morphological features, cultural characteristics and molecular identification. The pathogenicity was confirmed by Koch's postulates. This is the first report of natural infection by S. solani causing leaf spot on wild eggplant in China.
