In the 21st century, technology is constantly evolving. For agriculture to follow the sustainable development of science and technology, it is necessary to accelerate the development of agricultural machinery and develop more high-tech modern agricultural equipment. Agricultural drones for crop protection are an important embodiment of scientific and technological agriculture, as they can perform large-scale agricultural operations and promote the modernization of farming. In recent years, the application scope of crop protection drones has gradually expanded—whether it's fields, orchards, tea plantations, etc.—drones can be seen everywhere. Various regions also consistently issue policies on subsidies for purchasing crop protection drones, while the market for these drones is experiencing explosive growth. Statistics show that the number of crop protection drones in China has currently exceeded 100,000 units.

Beyond direct fertilization and pesticide application, unmanned aerial vehicles (UAVs) can also deeply integrate with agriculture through modern information technologies such as the Internet of Things, artificial intelligence, and big data to achieve precise information perception management and intelligent control over the entire agricultural production process. The four main applications of intelligent agricultural production environments are UAVs, crop protection, autonomous driving in farming, enhanced seed selection, and agricultural IoT. As a vertical application area of intelligent agriculture, crop protection via UAVs depends on the development of intelligent farming.
