Interpretive Summary: The rapid development and integration of unmanned aerial spray systems in the modern agricultural production environment has the potential to significantly impact current standard practices and methodologies. While the potential benefit is significant, there is a great deal of unknowns with regard to the overall efficiency, efficacy and potential environmental impact of these systems. Through a review of current international literature, a baseline understanding of the current state of the art, the critical limitations and the knowledge gaps with respect to these systems is developed and discussed in order to provide a guide for research and development moving forward.

Technical Abstract: With changing climate and farmland ecological conditions, pest outbreaks in agricultural landscapes are becoming more frequent, increasing the need for improved crop production tools and methods. UAV-based agricultural spraying is anticipated to be an important new technology in providing efficient and effective application for crop protection products. This paper reviewed and summarized the status of current research and progress of UAV application technologies for plant protection, and discussed the characteristic of atomization on unmanned aircraft application systems with a focus on spray application of agrichemicals. Additionally, the factors influencing spraying performance and a number of key technologies for reducing drift and enhancing application efficiency are considered. Based on the reviewed literature, future developments and impacts of UAV technologies are projected.
