Abstract Corn (Zea mays L.) is an important crop in the Philippines, but an insect, the fall army worm (FAW) with scientific name Spodoptera frugiperda, threatens its productivity, causing a significant yield loss since it started invading corn crop in the country. They can be controlled with chemical pesticides, but they can pose risks to human health, non-target organisms, and the environment. This underscores the need to seed safer control alternatives like the entomopathogenic fungi (EPF). The study evaluated the effect of Beauveria bassiana at different conidial concentration levels of 1×107, 1×108, and 1×109 against the FAW larva at the third instar on potted corn plants at Northern Mindanao Agricultural Crops and Livestock Research Complex. The experimental area was laid out in a Randomized Complete Block Design (RCBD) with three replicates. The study aims to determine the effective concentration of EPF that can control fall army worm and assess the damage caused by fall army worm inoculated with EPF to the corn plants. The results revealed that Beauveria bassiana at 1×109 conidia/mL obtained the highest mortality and reduced the feeding damage incurred to the corn plant. To further assess the result of the experiment, a multi-location trial is recommended.
