What is the primary use for a hollow cone nozzle?

The primary use of a hollow cone nozzle is to create a circular spray pattern that evenly covers foliage. This design allows for an even distribution of pesticides or herbicides over the surface of plants, making it effective for targeting pests and diseases. The hollow cone nozzle atomizes the liquid into fine droplets that can penetrate the plant canopy, ensuring that both upper and lower leaf surfaces receive adequate coverage.

Other options correspond to different nozzle designs or applications. For instance, applying a narrow band of herbicide is typically better suited to flat fan nozzles, which direct the spray more precisely with a controlled width. Broadcast spraying and some band applications also align with flat fan or air-induction nozzles, which provide a wider distribution for covering large areas efficiently. Delivering solid jets to distant targets generally relies on a different nozzle configuration, such as an adjustable nozzle designed for long-range application, rather than a hollow cone design.
