Which of the following statements about nozzles is true?

The statement that identifies hollow cone, broadcast, and oscillating as the main types of nozzles is accurate because these types encompass the primary designs used for various agricultural spraying applications.

Hollow cone nozzles produce a spray pattern that resembles a hollow cone, allowing for thorough coverage of plant surfaces, making them ideal for applications requiring good canopy penetration, such as fungicides and insecticides. Broadcast nozzles are designed to deliver a uniform spray over a wide area, ensuring broad coverage for herbicides or fertilizers. Oscillating nozzles distribute liquid in a back-and-forth motion, which can help achieve more even coverage on large areas and can be adjusted for different applications.

Understanding these main types is essential for selecting the appropriate nozzle for specific agricultural needs, as each type has unique functionalities that cater to different spraying goals. This knowledge contributes to better application efficacy and efficiency in various agricultural practices.
