What is the primary use of flooding fan nozzles?

• A. Surface application of herbicides incorporated into soil.
• B. Foliar spraying on leaves.
• C. Root zone soil injection.
• D. Aerial spraying from aircraft.

Answer: (A)

Flooding fan nozzles are designed to lay down a broad, heavy spray over the soil surface with large droplets, minimizing drift. This makes them ideal for applying herbicides that are intended to stay on or just above the soil so they can be incorporated into the soil, often through irrigation or rainfall. They’re not meant for spraying onto leaves (foliar) or for injecting herbicides into the root zone, and they’re not used for spraying from aircraft. So the primary use is surface application of soil-incorporated herbicides.
