"We have many different field trials... to prove that drones can be equivalent in performance or even better compared to ground sprayer or airplanes. Efficacy depends on following label directions and spraying under the right conditions."
"So the difference was 5 feet in height and also 100 micrometre in droplet size difference... those two things combined reduced the herbicide downwind drift by over 50 per cent."
"While low-volume application is possible, coverage and efficacy cannot be sacrificed. Unlocking the full value of drones will depend on continued research and supportive policy."
Research indicates that drone-based pesticide application can be as effective as traditional methods when operated correctly. Key performance measures include canopy penetration and spray deposition, with drones using lower water volumes. Adjustments in flight height and droplet size can drastically reduce herbicide drift. As Canada considers regulatory changes, maintaining coverage and efficacy in low-volume applications is crucial. Continued research and supportive policies are essential for maximizing the potential of drone technology in agriculture.
