The present study investigated the seasonal dynamics of phylloplane mycoflora associated with Vigna radiata (mung bean) cultivated in the Arjuni/Mor Taluka of Gondia District, Maharashtra, India, in 2022. Phylloplane fungal diversity was assessed across three distinct seasons, summer, monsoon, and winter. Thirteen fungal species were identified, with Aspergillus flavus (80%), Aspergillus niger (73.33%), and Penicillium notatum (73.33%) exhibiting the highest overall frequencies. Seasonal variation influenced both the frequency and relative abundance of fungal taxa. The monsoon season had the highest species richness (13 species) and diversity indices (Shannon-Wiener H' = 2.5142, Simpson's D = 0.9147), indicating peak fungal activity, likely due to favorable humidity and temperature conditions. In contrast, the summer exhibited the lowest species richness (10 species). The dominant fungal genera include Aspergillus, Penicillium, Curvularia, and Fusarium, each with varying levels of occurrence across seasons. This study underscores the dynamic nature of phylloplane fungal communities in response to seasonal environmental changes and provides a baseline for future ecological and pathological investigations of mung bean agroecosystems.
