Abstract

AbstractPepino (Solanum muricatumvar. pepino) plants were found affected by an extensive leaf spot caused by plant pathogenic fungi during a survey in the Cameron highlands, Pahang state, Malaysia. Symptomatic leaf samples were collected from infected pepino plants and cultivated onPDAmedium, and the pathogen was isolated and purified; then, consequently, all isolates were identified asStemphylium lycopersicion the basis of their cultural and morphological characteristics and combined sequences of the internal transcribed spacer (ITS) and glyceraldehyde‐3‐phosphate dehydrogenase (gpd) regions. A pathogenicity assay on detached leaves further confirmed thatS. lycopersicicauses leaf spot disease. To the best of our knowledge, this is the first report ofS. lycopersicicausing leaf spot on pepino in Malaysia and worldwide.
