How does a hollow cone nozzle disperse pesticide?

• A. Sprays in a solid cone with droplets throughout
• B. Sprays in a circle, with no droplets in the center
• C. Creates a wide fan of spray
• D. Generates a mist that settles on the surface

Answer: (B)

A hollow cone nozzle is designed to produce a spray pattern that resembles a cone shape with a hollow center. This design allows for a specific distribution of droplets, creating a spray that is denser at the edges and minimal or nonexistent in the center. The primary purpose of this configuration is to ensure that the pesticide reaches the target area effectively, particularly useful when treating plants or areas with irregular shapes where coverage is critical. This type of nozzle is particularly advantageous in scenarios where thorough coverage is necessary along the perimeter of the treated area while the center may not require direct application. The unique dispersion pattern of the hollow cone nozzle allows for effective application of substances like fungicides or insecticides, particularly on leafy crops where canopy penetration is necessary. In contrast, other nozzle designs, such as solid cone or full cone nozzles, would not provide the same hollow center effect and would distribute droplets more uniformly throughout, or create different spray patterns unsuitable for specific applications.
