- 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
Comparison of traditional vs PWM
435hp Versatile tractor pulling a 1500 gal sprayer with 83 ft booms
Speed examples
- 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
