Aspergillus leaf spot of field bindweed ( Convolvulus arvensis L.) caused by Aspergillus niger in China

Leaf spot was found on field bindweed (Convolvulus arvensis L.) in Shihezi City, Xinjiang Province, China, during the summer of 2015. Pathogens were isolated from the infected leaves of field bindweed and identified as Aspergillus niger based on morphological and molecular analyses (internal transcribed spacer rDNA and β-tubulin gene). A pathogenicity test confirmed that Aspergillus niger caused the healthy leaves of field bindweed to become diseased. To our knowledge, this is the first report of field bindweed infected naturally by A. niger.
