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.  2lcccTHEDIS  c24278d24278  00102lcc4070aMMSU_MAINbMMSU_MAINcTHESESd2024-12-09i7503pUTHESIS-7503r2024-12-09w2024-12-09yTHEDISzRoom Use Only
