Latest spray drift research
By Queensland Country Life
University of Queensland research is helping identify spray dirft reduction techniques.
University of Queensland researcher Andrew Hewitt said Australia leads the world in spray drift research thanks to wind-tunnel research and field-testing of ground spraying.
Rather than focus solely on droplet size, their research is also looking at their velocities, directions, trajectories and inclusions, such as air bubbles and emulsions, as well as drift potential through studies in several different working sections of our wind tunnel.
The latest drift-management tools include apps to determine suitable spraying conditions, and a new spray drift-mitigating adjuvant, Dead Sure, developed by Caltex, which can reduce spray drift by up to 70 per cent without reduction in herbicide efficacy when using low-drift nozzles.
