The causal agent of leaf spot disease of oil palm (Elaeis guineensis) seedling nurseries in Thailand was identified as Curvularia oryzae. The fungus was isolated from leaves with disease symptoms, characterized by morphological properties, and pathogenicity tested. The identity of the phytopathogenic fungus was confirmed through polymerase chain reaction analysis using internal transcribed spacer (ITS) primers, which amplified about a 1 kb product. Sequencing this DNA product confirmed this pathogen was C. oryzae. Furthermore, the pathogenicity test showed that C. oryzae could infect oil palm seedlings. 相似文献
