How does a hydraulic sprayer work in pesticide application?

A hydraulic sprayer operates by using a pump to generate pressure, which forces a mixture of pesticide and water through a series of hoses and nozzles. In this system, water acts as a carrier fluid, diluting the pesticide to ensure an even distribution during application. This dilution is essential because it allows the pesticide to be effectively dispersed in a fine mist or spray, resulting in better coverage of the target area. The nozzle design further assists in achieving the desired droplet size, which is crucial for optimal coverage and efficiency in pest control.

The other choices do not accurately describe how a hydraulic sprayer functions. Releasing gases into the air, spreading granules, and forming vapors from solid pesticides involve different mechanisms that do not align with the principles of hydraulic spraying and its reliance on liquid solutions for effective pesticide application.
