In the era of the 4th Industrial Revolution, drone technology has seen remarkable advancements, in agriculture. The unmanned aerial vehicles (UAVs) have been introduced to address issues such as the spread of pesticides in rural areas, caused by the use of conventional aircraft for pest control, and the aging farming communities. The utilization of drones for pesticide spraying, whether manned or unmanned, has seen an increase of the risk associated with pesticide spread problem. However, there are shortcomings in terms of specialized training related to spraying drones and the qualifications required for pest control operators, as well as a lack of manuals to address various issues on the field. The purpose of spraying drones is to eliminate pests and protect crops to increase productivity, making the widespread adoption of spraying drones crucial in replacing aging labor and reducing traditional spraying times. By acquiring various aerial photographs through drones, the progression of pests and the effectiveness of UAV pesticides can be analyzed, facilitating pest management. This paper aims to resolve operational challenges in spraying drone operations and manage pest control issues on-site based on aerial photography data, applying management techniques utilizing drones for comparison and analysis of the quality of public reserve grains and market-isolated dry rice. It is intended to use this study as a foundational research on drone spraying operations considering pests, integrating it with management and control systems in the future.
