Abstract
Collapsed vines of sweet potato (Ipomoea batatas) plants were observed in Jining fields in September 2019. In some cases, the whole plant had been killed due to the infection of crown. The size of sclerotia formed on infected tissues ranged from 0.6 to 1.5 cm in diameter. A number of sclerotia were sampled from infected fields and transferred to laboratory. After molecular assessment of the isolate SSd925 and fulfillment of Koch’s Postulates, the pathogen was identified as Sclerotinia sclerotiorum. To our knowledge, this is the first report of S. sclerotiorum on sweet potato in China.
