On-field spray downwash characterisation and comparison of Agras T10 and T50 UAV for spray application
Pagliai et al. (University of Florence), Wageningen Academic Publishers, 2025-06-18In field measurements of spray downwash and deposition, the T50's measured effective swath was about 3.5-4.5 m, at the low end of or below the maker's published 4-11 m spray width range.
Government or academic field trial Shows a limitation
Vloeistofverdeling en driftdepositie van spuitdrones (liquid distribution and drift deposition of spraying drones), report WPR-1426
Wageningen Plant Research, 2025Deposition measured with collector cloths on grass: the T50 at its coarsest droplet setting and 1.5 m height gave indicative drift deposition about 4 times higher than a T10 fitted with 75% drift-reducing nozzles. (Spraying from the air is banned in the Netherlands; this was a research test.)
Government or academic field trial Supports the job fit
The Influence of Unmanned Aerial Vehicle Wind Field on the Pesticide Droplet Deposition and Control Effect in Cotton Fields
Li et al., Shihezi University; Agronomy 15(5):1221 (MDPI), 2025-05-17Cotton field trial comparing four DJI spraying drones (T30, T40, T50, T60) with a boom sprayer: pesticide utilisation was 75.5-77.9% for the drones versus 58.9% for the boom sprayer.
