Leaf spot and blight diseases are major factors limiting forest seedling production in nurseries, including economically important species, such as mahogany (Swietenia mahagoni). However, specific information on their incidence, severity, and causative pathogens remains limited. This study aimed to evaluate the incidence and severity of the diseases and identify the pathogenic fungi associated with mahogany seedlings at Rumpin Nursery, Bogor Regency. Observations were conducted on 3- and 4-month-old seedlings in the open growth area, with a 10% sampling intensity. Leaf samples showing symptoms were isolated, tested using Kochs postulate, and analyzed using ANOVA. Pathogen identification was performed through both morphological characterization and molecular analysis using ITS rDNA sequencing. The results showed a very high incidence of disease, namely 95.44% (3 months old) and 92.66% (4 months old), with a moderately severe severity (44.72% and 44.20%). Five types of pathogenic fungi were identified, namely Corynespora cassiicola, Pseudopestalotiopsis theae, Colletotrichum fruticola, Colletotrichum gloeosporioides, and Bipolaris setariae. The presence of pathogens with a wide host range, the ability to survive saprophytically, and their capacity to spread through water and air suggest that nurseries can serve as sources of inoculum and pathways for pathogen dissemination. Therefore, integrated disease management should be emphasized, incorporating sanitation, optimal spacing, irrigation control, and the use of biological agents.

This study revealed a very high incidence of leaf spot and blight diseases in mahogany seedlings at Rumpin Nursery, caused by five identified pathogenic fungi.The findings highlight the role of nursery environments as potential sources and pathways for pathogen spread due to the pathogens wide host range and ability to survive saprophytically.Therefore, implementing integrated disease management strategies, including sanitation, optimal spacing, irrigation control, and biological control agents, is crucial for maintaining healthy mahogany seedling production.

Penelitian lebih lanjut perlu dilakukan untuk memahami dinamika penyakit pada berbagai umur bibit dan musim, serta interaksi antara inang, patogen, dan faktor lingkungan. Studi mendalam mengenai efektivitas agen hayati lokal dalam menekan pertumbuhan patogen, khususnya Corynespora cassiicola, Pseudopestalotiopsis theae, Colletotrichum fruticola, Colletotrichum gloeosporioides, dan Bipolaris setariae, perlu diinvestigasi. Selain itu, penelitian mengenai potensi resistensi bibit mahoni terhadap patogen-patogen tersebut, melalui seleksi bibit unggul atau teknik pemuliaan tanaman, dapat memberikan solusi jangka panjang untuk pengendalian penyakit. Penelitian ini diharapkan dapat memberikan informasi penting bagi pengembangan strategi pengelolaan penyakit yang lebih efektif dan berkelanjutan di persemaian mahoni.
