摘　　要：Insect infestation attacks in agricultural ecosystems are becoming more common because of global warming as well as farmland environmental circumstances,necessitating the development of new crop production technology.Pesticide application is one of the most common strategies for protecting the entire growing period of plants or shrubs against pests and pathogens in farms.The rapid,effective,and profitable application of plant control substances via unmanned aerial vehicle(UAV)crop spraying is anticipated to be a key new technique.When compared to ground spraying,UAV spraying saves chemicals,water,time,does not damage crop plants or balls of crop,and does not create soil compaction.When using UAV,pesticide drift and deposition must be managed in order to use pesticides safely,effectively,and efficiently.This paper focuses on agrochemical spraying by unmanned aerial vehicles and the key parameters that influence spray effectiveness,such as the operating parameters of nozzle type,flying speed,flight height,type of nozzle,and type of UAV model,for reducing drift and increasing application efficiency.The multirotor UAV is most suitable for spraying due to its fast operation,safety,not requiring a runway for takeoff and landing,and lower cost as compared to fixed-wing and VTOL.UAVs can also be used for crop disease identification,soil health monitoring,livestock monitoring,field mapping,etc.This paper aims to review the development of various UAV models,optimization of operating parameters,effect of nozzle on UAV spraying,characterization of droplet deposition,drift reduction technology,UAV-based remote sensing for plant protection,and cost comparison of UAV to conventional ground sprayer.
