| Abstract/Contents: | "Agricultural spray drones (ASD) have become increasingly accessible in recent years, but little is known regarding their use for pest control. Only a few studies have evaluated weed control efficacy, and these generally focus on canopy penetration compared with conventional ground-based sprayers. (Chen et al. 2018; Martin et al. 2020) To utilize ASD for pest control, a uniform spray deposition pattern should be guaranteed to deliver recommended rates of pesticides. Field trials were conducted at Virginia Tech's Glade Road Research Facility in Blacksburg, VA, USA to examine the influence of five different spray heights (2, 4, 6, 8, and 10-m) of ASD (DJI MG1P, China) on spray deposition pattern, and it is compared to the spray deposition pattern of a ground-based sprayer. Total 30-m x 0.3-m white craft paper was clipped on top of rigid vinyl and placed on level turf. 50% Blazon blue dye (Milliken, USA) solution was sprayed with ASD and ground-based sprayer moving perpendicular to the paper. Then, the paper was cut, scanned, and analyzed with Turf Analyzer software (Green Research Services, USA) or with the absorbance of extracted dye via spectrophotometer. Polynomial regression curves were generated for the area above, below, and total deviation from the expected deposition pattern curve. It shows that the ASD over-applied to the targeted area when flown at lower heights and under-applied when flown at higher heights. In addition, the ASDs deposition pattern improved in uniformity as the ASD height increased. In summary, the ASD operated at 8 or 10 m delivered a smoother pattern overall, less deposition in the targeted area, and more deposition outside the targeted area (significant pattern at up to 14 m on either side of the drone). The results suggest that ASD applications will deviate significantly from expected deposition patterns and more so than the deposition patterns delivered by ground-based sprayers." |
