Dutch company Wingssprayer was set up by the spraying contractor Harrie Hoeben 12 years ago with the aim of putting all his ideas for reducing spray drift into commercial practice, His concept for a wing sprayer deflection system emerged back in 2010, and, in broad outline, the idea is to use a purpose-developed aerofoil to exploit airflow to reduce spray drift. Several developments along the way have refined the concept, including the nozzle holders that simplify installation and reduce overall weight.
