What color indicates very fine spray nozzles?

The color that indicates very fine spray nozzles is red. Different colors are used to categorize spray nozzles based on their flow rates, droplet sizes, and other characteristics to facilitate selection for various aerial application tasks.

Red nozzles are specifically assigned to represent very fine spray patterns, which are ideal for herbicides and pesticides that require small droplet sizes for effective coverage and penetration into the crop canopy. This is crucial in aerial application, where precise droplet size can greatly influence the efficacy of the product being applied, helping to minimize drift and ensure the pesticide reaches its target area effectively.

Understanding the color coding system for nozzles helps applicators choose the correct nozzle for specific applications, maximizing the effectiveness of their treatments and improving safety without causing harm to non-target areas.
