What are the three main functions performed by nozzles during pesticide application?

The correct answer highlights three essential functions of nozzles during pesticide application: regulating spray volume, atomizing the mixture, and dispersing the spray.

Regulating spray volume is crucial because it determines the amount of pesticide being applied to a given area, ensuring that the application is efficient and effective. Nozzles are designed to manage the flow rate, which directly impacts the concentration of the pesticide on the target surface.

Atomizing the mix refers to the process of breaking the liquid pesticide into fine droplets. This is vital for achieving a uniform distribution over the area being treated, as smaller droplets increase the coverage and enhance the likelihood of the pesticide adhering to the target pests or surfaces.

Dispersing the spray involves spreading the atomized droplets evenly over a large area. This function is important to ensure that the pesticide reaches all intended spots, maximizing its effectiveness while minimizing the risk of runoff or drift.

In contrast, other options fail to encompass the primary functions of nozzles accurately. For example, controlling temperature is not a function performed by nozzles, nor do they measure pressure or count droplets. These tasks are important in the overall application process but are not specific to what the nozzle itself does.
