Postharvest rot on carrot caused by Ceratocystis fimbriata and Chalaropsis thielavioides (equivalent to Thielaviopsis thielavioides) in China

摘要

In April 2012, postharvest carrot roots were found with circular black lesions and more often rotting tissue covered with white to black mould in farmer markets around Kunming city, Yunnan Province, China. Based on pathogenicity, morphology, and sequence of the rDNA internal transcribed spacer, Ceratocystis fimbriata caused the black lesions and Chalaropsis thielavioides (equivalent to Thielaviopsis thielavioides) caused the moldy rot. This is the first report of C. fimbriata and C. thielavioides as pathogens of a postharvest rot and mould of carrot (Daucus carota) in China. Better understanding of their incidence and ecology is needed to control these postharvest diseases.
