The color blue signifies which type of spray nozzle?

The color blue typically signifies a coarse spray nozzle. Coarse nozzles are designed to produce larger droplets of spray, which can minimize drift and provide better coverage on target surfaces, particularly in aerial applications. These nozzles are often preferred when applying pesticides or fertilizers to ensure that the material reaches the intended area effectively while reducing the potential for off-target movement, which can occur with smaller droplets.

Coarse nozzles are advantageous in windy conditions since their larger droplets are less susceptible to being carried away by air currents, making them a popular choice among aerial applicators who need to maintain efficiency and precision during application. The color-coding system for nozzles helps operators quickly identify the intended use and characteristics of the nozzle type, ensuring they select the appropriate one for their specific application needs.
