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