What color represents coarse droplets when referring to nozzles?

In the context of nozzle color coding for aerial applicators, yellow is designated to represent coarse droplets. This classification system helps applicators quickly identify nozzle types and their droplet sizes, which is crucial for ensuring proper application rates and minimizing drift. Coarse droplets are generally preferred in situations where reduced drift is essential, as they tend to fall to the ground more quickly compared to finer droplets.

Each color in the coding system signifies specific droplet sizes, helping aerial applicators make informed decisions about the application method based on environmental conditions and target areas. Understanding these color codes is critical for effective and safe pesticide application, directly impacting both efficacy and regulatory compliance.
