Selecting spraying nozzles for crop protection products

To select the required spraying nozzle, the following information must be known:

  • Application rate in l/ha

  • Working speed in km/h

  • Desired atomisation characteristic: fine droplets 5, medium droplets 6 or coarse droplets 7

  1. Determine the operating point 1 for the desired application rate and the working speed.
  2. Draw a vertical line downward from the operating point, until the line intersects the characteristic curve for the nozzle cross-section 3 in the area of the desired atomisation characteristic.
  3. The nozzle type 4, the nozzle cross-section 8 and the possible spray pressure range 2 are specified in the diagram.
