First report of anthracnose on Cynanchum atratum caused by Colletotrichum destructivum in China.
In September 2014, light brown spots (3-9 mm) with nut-brown annulations that gradually enlarged and turned black in the centre, were observed on leaves of Vincetoxicum atratum in Changchun Medicinal Garden, Jilin, China. The disease symptoms on V. atratum leaves were believed as anthracnose. The causal pathogen was identified as Colletotrichum destructivum based on morphological, molecular and pathogenicity analyses. This is thought to be the first report of anthracnose on V. atratum caused by C. destructivum in China.
