Which color signifies a very coarse spray nozzle?

The color that signifies a very coarse spray nozzle is green. In aerial application and pesticide spraying, various nozzle colors are standardized to indicate different spray qualities, including droplet size. A green nozzle is specifically designed to produce very coarse droplets, which are important in applications where minimizing drift is a priority.

Coarse droplets are less susceptible to wind drift, making them ideal for targeting specific areas and reducing the likelihood of off-target applications that could affect surrounding crops, non-target plants, or bodies of water. Understanding these color codes is essential for operators to choose the appropriate nozzle type based on the requirements of the job, environmental conditions, and the type of pesticide being used.
