Cordana musae (Zimm.) Höhnel is the fungal pathogen responsible for the cordana leaf spot disease in many countries where banana is widely produced. The pathogen causes significant concern for farmers due to its destructive symptoms, particularly the appearance of large diamond-shaped spots on leaves and extensive tissue damage. Understanding how the pathogen invades and colonizes host tissues is critical for developing effective management strategies. Thus, the present study investigates the histopathological features and disease development of C. musae in two banana cultivars, Cardaba and Lakatan, to assess varietal differences in conidial morphology, symptom expression, and pathogen behavior. Leaf tissues were sectioned using a hand microtome with the aid of a cassava petiole, and sections were stained with 0.1% acid fuchsin in lactophenol for microscopic examination of the pathogen morphology and progression. Results revealed that the leaf spot symptoms caused by C. musae on banana leaves varied between cultivars. The pathogen in Cardaba variety exhibited smaller, oval to elongated lesions, whereas in Lakatan variety, it displayed small, oval to expanded lesions with diverse colorations, ultimately affecting photosynthetic activity of the plant. Microscopic examination further revealed the variations in the fungal morphology of conidia between Cardaba and Lakatan, suggesting distinct host-pathogen dynamics that may influence disease progression and management strategies. Further studies are needed to comprehensively elucidate the host-pathogen interactions of Cordana leaf spot disease on across banana varieties. Future research may focus on investigating the genetic basis of resistance, the role of environmental factors on disease development, and the efficacy of integrated disease management strategies.
