What factors are influenced by the nozzle in a spray system?

The correct choice highlights that the nozzle in a spray system has a significant impact on several key factors: spray pattern, droplet size, and flow rate.

The spray pattern refers to the distribution of the spray in terms of width and coverage, which is influenced by the design of the nozzle and the pressure at which the liquid is released. A nozzle designed for a wide spray pattern will disperse the liquid more broadly, while one designed for a narrow spray may focus the liquid in a tighter stream.

Droplet size is also a crucial factor, as it affects how the pesticide interacts with the target species, including how well it adheres to surfaces, how easily it can be absorbed by plants, and how wind or evaporation might affect it. Different nozzles can produce varying droplet sizes; for example, a nozzle designed for fine mist may help in achieving better coverage on small, delicate plants.

Flow rate is the amount of liquid that the nozzle delivers over a specific period and is determined by the nozzle's design and the pressure applied in the system. The ability to control flow rate is critical in ensuring that the right amount of pesticide is applied for effective pest control.

Together, these factors influenced by the nozzle significantly affect the efficiency and effectiveness of
