• Controllable factors contributing to drift able droplets
    • Small nozzle size
    • High boom pressure
  • With the use of PWM pressure control you increase your nozzle size
  • You can maintain a constant pressure over a larger speed range
  • You have the ability to lower your pressure spraying against a susceptible crop while maintaining speed
  • Herbicides work best when they are applied at the correct droplet size
    • Too small and they may drift off target
    • Too large and they can bounce off target
    • The volume of eight 250 micron droplets equals the volume of one 500 micron droplet

Speed examples

speed

  • You are able to maintain a constant droplet size over a greater speed range
  • Borders, ditches and difficult parts of the field get the weeds killed also
  • Where conditions allow, greater speeds are achieved with less risk of drift
