Agriculture on the wings of science and technology: plant protection unmanned aerial vehicle (UAV) low-volume spraying technology reduces pesticide use and boosts control efficacy

Modern aviation industry for plant protection, represented by the low-volume pesticide application technology of plant protection unmanned aerial vehicle (UAV), developed rapidly during the 13th Five-Year Plan period of China. A large number of scientific research and field trials showed that the use of plant protection UAV application technology could increase the deposition of pesticides on target crops and reduce the loss of pesticides, and thus achieve precise reduction in pesticide application, which help solve the pest control problem when ground machinery cannot be operated. Pesticide application technology of UAV is characterized by the separation of man and machine, avoiding the occurrence of pesticide poisoning, reducing labor intensity, and greatly improving work efficiency. It achieves the purpose of reducing pesticide use and improving pesticide utilization. This article takes rice as an example to summarize the role of plant protection UAV in pesticide reduction, rice disease and insect pest control, technology simplification, pesticide utilization, rice yield increase, and cost-benefit improvement. The rapid development of the aviation industry for plant protection has accelerated the quality improvement of plant protection unmanned aircraft intelligent precision control system and the pace of new technology research and development. The popularity of plant protection UAV has drawn forward an urgent need for the research and development of pesticide, adjuvants and pesticide application drift risk control technologies. This article further summarizes the role and future development direction of plant protection UAV low-volume spray technology in reducing pesticide application and increasing efficiency.
