Drones can now detect subtle soybean canopy damage from dicamba at one ten-thousandth of the herbicide’s label rate — simulating vapor drift — eight days after application. That advancement in remote sensing from the University of Illinois Urbana-Champaign provides a science-based tool to accurately detect and report crop damage at the field scale, reducing human error and bias.
