Evaluating Integrated Pest Management Effects on Corn Resistance and Productivity Against Major Insect Pests in Indonesia

Abstract

Integrated Pest Control (PHT) is a strategic approach in corn cultivation to suppress major pest attacks effectively, sustainably, and environmentally friendly. Corn plants in Indonesia are susceptible to various pests such as armyworms (Spodoptera frugiperda), stem borers (Ostrinia furnacalis), and aphids (Aphis maidis) which can significantly reduce productivity. Evaluation of the implementation of PHT is needed to determine the effectiveness of control techniques such as pest monitoring, the use of resistant varieties, agroecosystem management, and the use of natural enemies. This study aims to examine the implementation of PHT in corn fields and assess its impact on the level of pest attacks and increasing plant resilience. The results of the evaluation showed that the combination of intensive monitoring, release of biological agents, land sanitation, and the use of selective pesticides based on economic thresholds was able to reduce pest attacks by more than 45% and increase productivity by 15–25% compared to conventional methods. This study confirms that PHT is an effective and sustainable approach in pest control in corn plants.
