520			_aThe study on the collection and identification of major fungal diseases on mung bean (Vigna radiata L.) in San Bernabe, Sarrat Ilocos Norte was conducted from February to April 2022. It aimed to assess and characterized fungal diseases affecting the seedling, vegetative, and reproductive stages of the Pag-asa 19 variety. The study used descriptive research design to describe the results of the different activities: field survey, collection of plant samples, identification of major fungal diseases, and characterization of the major fungal diseases of mung bean. Results showed that there are fungal pathogens attacking mung bean plants in the field at San Bernabe, Sarrat Ilocos Norte. The field that was surveyed has a total of 2500 m². Three (3) fungal diseases were observed affecting mung bean during the seedling, vegetative, and reproductive stage. During the seedling stage, the symptoms observed were wilting, yellowing of leaves, and reddish-brown lesion on the stem. The fungal pathogen, Fusarium sp., were isolated and observed during this stage. At vegetative stage, infected plants showed dark brown to black color lesion on the leaves with pale yellow margins. Leaf spot have a distinct ring, varying in shape and sizes that gives a rustic image, which eventually leads to the death of the leaves. The fungal pathogen, Culvularia sp., was isolated during this stage and was identified as the causal agent of Culvularia leaf spot. Furthermore, at the reproductive stage, almost the surface of the leaves was infected. Spots were dark brown to black causing the leaves to turn yellow and fall off. The spots reduced the photosynthetic area of the leaves. The fungal pathogen, Phyllosticta sp., was identified during this stage causing leaf spots. Considering the results of the study, there are (3) fungal pathogens causing major fungal diseases on mung bean in the area. These fungal diseases have potential to become economically significant in the next season if without proper management. Nonetheless, to accurately estimate yield loss, the extent of these fungal diseases must be subjected to pathogenicity test to verify their identity.
