| Abstract: | In June 2021, a new disease with necrotic symptoms affecting the leaves of Cucurbita pepo was observed in Yan'an city, Shaanxi province, China. Disease samples were collected and fifteen isolates (cucup1-cucup15) were obtained by tissue isolation and single spore purification methods. According to the morphological features and analysis of rDNA internal transcribed spacer (ITS) and RNA polymerase II second largest subunit (RPB2) sequences, the fungal isolates were identified as Curvularia spicifera, a new pathogen on C. pepo. The pathogenicity assay confirmed that C. spicifera was the pathogen causing this disease. This is the first record of leaf necrotic disease caused by C. spicifera in China. |
