Bachelor of Science in Agriculture, Major in Crop Protection – Plant Pathology. Don Mariano Marcos Memorial State University – North La Union Campus, College of Agriculture, Bacnotan, La Union. Adviser: Angeles, Yolanda B., Ph.D. Corn (Zea mays L.) is one of the largest plant-based sources of food and considered as the second staple crop next to rice in the Philippines. It is regarded as one of the world’s most productive and predominant crops because of its usefulness for both human and livestock consumption as well as for industrial purposes. This study aimed to determine the occurrence, identify the etiology, know the morphological characteristics of the observed leaf spot diseases, and test the pathogenicity of the fungal pathogens infecting corn in Tagudin, Ilocos Sur particularly on the five barangays: Pudoc East, Pudoc West, Lantag, Pacac, and Baritao. A total of 15 corn fields were randomly selected and surveyed for the presence of these fungal diseases during the dry season. The results of the survey showed that four genera of fungal diseases were present in the corn fields of Tagudin, with Curvularia sp. being the most prevalent from December to April, followed by Colletotrichum sp., Physoderma sp., and Bipolaris sp. The severity of these diseases varied across the different fields, with some fields showing only mild symptoms while others had severe disease outbreaks. The occurrence of these fungal diseases can have a significant impact on the yield and quality of corn in Tagudin. Therefore, it is essential for farmers to identify and manage these diseases effectively to minimize their impact on corn production. Overall, this study highlights the need for continued surveillance and management of corn diseases in the region to ensure sustainable corn production. | |
