What color is designated for coarse droplets in nozzle classification?

The correct answer is yellow, which is designated for coarse droplets in nozzle classification. This classification is important for aerial applicators because the size of the droplets affects how the pesticide is applied and how it interacts with the environment.

Coarse droplets reduce the potential for drift, which is a significant concern in aerial application. By using nozzles that produce coarse droplets, applicators can achieve better coverage on the target area while minimizing the risk of the product drifting away and affecting non-target areas. The color-coding system helps applicators quickly identify the right nozzles for the application they need, ensuring both efficacy and safety in their operations.
