Field evaluation of an unmanned aerial vehicle (UAV) sprayer: effect of spray volume on deposition and the control of pests and disease in wheat.

The UAV had comparable deposition and efficacy control to the EAP at a higher spray volume (> 16.8 L ha-1 ) with coarse nozzles, but exhibited inferior deposition and efficacy control at a lower spray volume (<9.0 L ha-1 ) with fine nozzles. © 2019 Society of Chemical Industry.
