摘要： A severe leaf spot disease was observed in a commercial tomato greenhouse in Dalian, Liaoning Province, China in January 2014. Typical symptoms included necrotic spots with dark brown, slightly sunken, irregular lesions on the leaves and stems, leading to wilting. The causative pathogen was identified as Fusarium proliferatum (Matsush.) Nirenberg on the basis of morphological characteristics and PCR amplification and sequence analysis of five genes, namely translation elongation factor-1 alpha (TEF), beta-tubulin (BT), fumonisin biosynthetic polyketide synthase (FUM1), histone H3 (H3) and calmodulin (Cal). Pathogenicity was confirmed by fulfilling Koch's postulates. To our knowledge, this is the first report of leaf spot disease on tomato caused by F. proliferatum in China.
