Hedera helix L. (common ivy) grows worldwide and is an evergreen root-climbing liana commonly used in parks, green belts (Metcalfe 2005), indoors as an ornamental, and as a traditional medicinal plant in China. In July 2019, a leaf wilt was observed on H. helix in Xiaofuhe wetland of Zibo, Shandong Province, China (36.79°N, 117.98°E). More than 100 m² of planting area was investigated, and the disease incidence reached about 30%. The place where the disease was found was a wetland park, mainly in a watery and humid environment. Initial symptoms on leaves appeared as small water-soaked lesions, yellow or brown in color and round or oval in shape. As the disease progressed, the area of the lesions gradually increased, forming round or irregular brown necrotic spots surrounded by a yellow halo, which eventually resulted in a wilt and death. To determine the causal pathogen, small pieces of the diseased tissue were collected and surface sterilized by 75% ethanol for 30 s followed by 5% NaClO for 1 min and then rinsed three times with sterile water. The treated samples were plated on potato dextrose agar (PDA) and incubated at 25°C for 2 days, and nine fungal isolates were obtained from 10 diseased leaves. The colonies were initially white, gradually turning gray-green to dark gray after 7 days, and the margin of the colony was regular, with abundant gray aerial mycelium. To verify identity, the partial coding genes of the internal transcribed spacer region, beta-tubulin, and translation elongation factor 1 alpha genes from the original isolate were amplified with primers ITS1/ITS4 (White et al. 1990), BT-2a/BT-2b (Glass et al. 1995), and EF1-728F/EF1-986R (Carbone et al. 1999), respectively. The sequenced genes (GenBank accession nos. MN633360, MN642587, and MN642588) exhibited 99.46, 100.00, and 99.00% homology with type specimen of Botryosphaeria dothidea CBS115476 (GenBank accession nos. KF293866, EU673106, and AY573218), respectively. The isolates were confirmed as B. dothidea on the basis of morphological and molecular results (Zhai et al. 2014). To assess pathogenicity, five healthy leaves from each of three 6-month-old healthy H. helix plants were wound inoculated with a sterilized needle. Mycelial plugs (about 5 mm in diameter) of B. dothidea from a 7-day-old culture on PDA were placed on the wounds, and five other sterile PDA plugs served as negative controls on the same leaves. All treated leaves and the whole plants were covered by sterilized plastic film and sprayed with water as needed. Ten days later, all inoculated plants developed similar symptoms to those previously observed outdoors, and the reisolated pathogen was identified as B. dothidea based on morphological and molecular results, whereas no symptoms appeared and no pathogen was isolated on negative controls. The pathogenicity test was repeated three times and showed similar results, confirming Koch’s postulates. To our knowledge, this is the first report on the presence of B. dothidea affecting H. helix plants in China. The discovery of this new disease is beneficial to the application and protection of H. helix, a common landscape and medicinal plant.
