Performance Evaluation of UAVs in Wheat Disease Control

Plant protection unmanned aircraft vehicles (UAVs) were developed rapidly in China. The operation performances of different models UAVs different. This paper systematically studied droplet deposition distribution; pesticide-mixture utilization rate; operational efficiency; wheat-disease control efficacy; and a comprehensive score three types UAVs, boom sprayer, knapsack sprayer. results showed the descending order penetration rate pesticide application equipment (PAE) was sprayer; UAVs; rates sprayer more than 50% while that electric only 27.8%. UAVs’ average labor productivity 5.75 ha per man-hour, which slightly less 21.3 times efficacy each machine on wheat Fusarium head blight 90%. performance 0.812, lower 0.929 for 3WPZ-700 self-propelled but much higher 0.399 3WBD-18 clearly potential improving efficiency, as well efficacy.
