What does the term "nozzle droplet spectrum" refer to?

The term "nozzle droplet spectrum" specifically refers to the range of droplet sizes produced by a nozzle during the application of liquids, such as pesticides. Understanding the droplet spectrum is crucial for ensuring effective application, as it directly influences factors like coverage, drift potential, and the effectiveness of the pesticide being used. Each droplet size interacts differently with air and the target surface, affecting how the chemical adheres to the plants or pests being targeted.

For instance, larger droplets may reduce drift but might not provide as even coverage, while smaller droplets increase coverage but can be more susceptible to wind drift and evaporation. Therefore, selecting the appropriate nozzle with the desired droplet spectrum is vital for accomplishing effective and safe pesticide application.
