What function does an agitation system serve in pesticide application?

An agitation system in a pesticide application context is essential for ensuring that the pesticide product is properly mixed and remains homogeneous throughout the application process. Pesticides can settle or separate over time, especially when they contain solid particles or are formulated as suspensions. The agitation system stirs or mixes the pesticide product within the sprayer, preventing any settling or clumping that could affect the effectiveness of the application. By maintaining a consistent mix, the system ensures that the correct concentration of the pesticide is delivered at all times, allowing for effective pest control and minimizing the risk of under- or over-application, which can be detrimental to both pest management efforts and environmental safety.

The other options listed involve functions that are not primarily the role of an agitation system. For instance, filtering air is not a key function of an agitation system; its main purpose is to mix the pesticide. Cooling the pesticide is also not a standard function associated with agitation systems. Similarly, controlling the speed of spray application relates more to the equipment configuration and nozzle design rather than to the agitation of the pesticide mixture itself.
