Abstract

Over the past ten years， the unmanned aerial system （UAS） for crop protection has been developing rapidly in China and has been used for more and more crops. It has been applied not only to primary food crops such as rice， wheat， corn and so on， but also to long-stalk plants such as rubber and areca for controlling diseases and insect pests. The low-volume application technology of UAS for crop protection has been initially formed in China such as nozzles setup， pesticide products， spray adjuvants， flight parameters. The control effects on diseases and insect pests， including rice leaf roller， rice sheath blight， wheat aphid and corn armyworm， are more than 80%. The UAS plays an important role in the control of diseases and insect pests in different provinces. However， during the spray application of UAS for crop protection， there are still some problems such as the UAS crash， phytotoxicity by droplet drifting， pesticide solution separation and precipitation， and control efficiency instability. Through summarizing and analyzing the successful experience and safety accidents of UAS for plant protection in the control of important diseases， pests and weeds， this paper proposes that the low-volume spray technology of UAS will be more widely applied and it will make great progress in the unmanned aerial vehicle （UAV） in terms of special agents and auxiliary agents， variable dosage， multisensor data fusion， multiple machine synergy， precise application， pesticide product standard and so on. It will provide technical support for the development of modern agriculture and intelligent agriculture.
