While the benefits of herbicides are well documented for row crop agriculture, there are often concerns about off-target movement of these products through spray drift. Hooded sprayers are drift reduction technology (DRT) tools that place a physical barrier around the nozzle to restrict most droplets from drifting horizontally. Hooded sprayers bring considerable benefits to ensure on-target applications, yet its adoption has been slow in the market. One reason might be due to the lack of documented cost-benefit analysis. This presentation will first provide an overview of hooded sprayer technology including its cost. Next, a few datasets from published literature as well as Bayer internal studies that document the benefits under field conditions will be presented. Finally, the presentation will provide some ideas as well as seek feedback on how to increase adoption of this excellent DRT for herbicide application.
