What color code corresponds to nozzles that produce extra fine spray droplets?

The color code that corresponds to nozzles producing extra fine spray droplets is purple. This color designation is part of a standard system used to help identify the droplet size produced by different nozzle types. Understanding these color codes is crucial for aerial application because they directly affect the efficacy and safety of pesticide application.

Extra fine droplets are typically used for applications where very precise coverage is necessary, such as for reaching difficult-to-penetrate areas in dense vegetation or where the target pest resides. The use of purple-coded nozzles is associated with minimizing drift, which is essential in preventing contamination of non-target areas and sensitive crops.

Knowing the significance of each color code helps operators choose the appropriate nozzle for their specific application needs, ensuring they adhere to both safety regulations and agricultural best practices.
