| 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, uniform spray deposition pattern should be guaranteed to deliver recommended rate of pesticide. Field trials were conducted on Virginia Tech's Glade Road Research Facility in Blacksburg, VA, USA to examine the influence of five different spray height (2, 4, 6, 8, and 10-m) of ASD (DJI MG-1P, 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 base and placed on the level fairways. 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) Polynomial regression curve was generated for the area above, below, and total deviation from the expected deposition pattern curve. It shows decreasing trends for area above and total deviation from the expected deposition pattern curve as the ASD height increases. For the area below expected curve, it increases as the ASD height increases. Data also indicate that maximum deviation from the expected spray volume is 60% higher for 2, 4, and 6-m ASD height than that of the ground-based sprayer. However, the minimum deviation from the expected spray volume for ground-based sprayer is at least 25% higher than all ASD heights. The results suggest that significant deviation from expected deposition pattern curve was observed on all ASD heights compared to the ground-based sprayer." |
