“…In general, applications have been performed between 1.0 m to 3.0 m of height and 1.0 m s -1 to 7.0 m s -1 of velocity, as can be observed in the works of Liao et al (2019), Wang et al (2020 c), Ahmad et al (2020), andChen et al (2020). Wang et al (2020 d) showed that it is critical to find a balance between height and speed to achieve a satisfactory application. Tang et al (2018) studied the effect of flight height on application quality with an RPA in citrus.…”

“…Choosing a tip that produces fine droplets with good deposition and density may result in better control efficacy (Chen et al, 2020;Yan et al, 2020). Besides, the addition of adjuvants may help improve effectiveness by ensuring better deposition and coverage of the target or by prolonging the retention of the plant protection product on the surface (Chen et al, 2020;Qin et al, 2018).…”

“…There may also be a loss of solution directly to the soil due to the non-retention by the foliar. Wang et al (2020 d) evaluated a single-engine combustion RPA operating in a pineapple crop in China and observed that 90% of the drift was concentrated at distances from 3.7 m to 46.5 m under different operational conditions. The authors pointed out that such observations are related to flight height and speed, type of RPA used, and the meteorological conditions of the study region.…”

The Unmanned Aerial Vehicle (UAV) sprayer has the advantages of high work efficiency, simple operation, and high safety factor, and has broad application prospects UAV sprayer are widely used in the agricultural field, and the application of UAV sprayer spraying technology in agriculture has provided convenience and increased profits for farmers, and has also become a research hotspot in the field of agriculture. In recent years, although research has been conducted on the feasibility and application effects of UAV sprayer spraying crown shaped plants, there have been no experiments or studies in the field of garden plants. This experiment conducted a droplet deposition experiment of UAV sprayer spraying garden plants, exploring the droplet deposition effect of UAV sprayer in the field of garden plants, and conducting experiments on the influence of spray volume and nozzle type on droplet deposition. The experimental results showed that the canopy performance of small and medium-sized garden plants was better at a flight altitude of 1.5m, a spray volume of 180L/hm2, and a flight speed of 2m/s. Reducing flight altitude, increasing spray volume, and reducing flight speed can improve the distribution of droplets in the canopy. This experiment lays the foundation for the application of UAV sprayer for the prevention and control of pests and diseases in garden plants, as well as for the application of growth regulators, and provides a basis for further innovative research in the field of garden plant application technology.

“…In the studies by Yan [14] et al and Yongjun [15] et al, the penetration and deposition of droplets in the target were directly related to plant shape, canopy volume, and leaf area. It is thus important to conduct studies in a variety of crops that could benefit from this technology.…”

The use of unmanned aerial vehicles (UAVs), or drones, to apply crop protection products has been increasing; however, because this is a recently developed technology, data about its efficacy in many crops are still scarce. The objective of this study was to evaluate the deposition of a spray applied to a soybean crop with a UAV at two flight speeds and compare it to that of spray applied with a ground-based sprayer. The experiment used a DJI AGRAS MG-1 UAV to spray a soybean crop at the R3 growth stage. The experiment consisted of three treatments with eight replicates for each; the spray was applied using the UAV flying at 15.4 km/h or 21.8 km/h or a CO 2 -pressurized backpack sprayer. The application rate was 10 L/hm 2 with the UAV and 115 L/hm 2 with the ground-based sprayer. The following parameters were evaluated: deposition of a tracer added to the spray solution (500 g/hm 2 in all treatments) in the upper and middle parts of the soybean plants using spectrophotometry and droplet coverage, density, and size spectrum using water-sensitive paper cards. Flight speed did not alter droplet coverage, density, or spectrum. The coverage in the middle layer of the soybean canopy was low whether application was by the ground-based application (1.2%) or by the UAV (0.2%), which demonstrated the difficulty of reaching that part of the plants. Tracer deposition in the upper and middle parts of the soybean plants from the UAV was similar to that obtained with the ground-based application.
