What is a characteristic of a mechanical agitation system?

A mechanical agitation system is primarily designed to help in the mixing of different substances, particularly when dealing with wettable powders. Wettable powders are formulations that require thorough mixing with a liquid to ensure uniform distribution and effectiveness when applied. The agitation provided by a mechanical system enhances the mixing process, ensuring that the particles are suspended properly within the liquid. This results in a more effective application of the pesticide, as it allows for an even distribution across the treated area.

In contrast, while maintaining pressure is important for the operation of some spraying systems, mechanical agitation specifically focuses on mixing rather than pressure maintenance. Improving flow rate might be a benefit of certain systems, but it's not the primary function of mechanical agitation. Lastly, when it comes to chemical storage, mechanical agitation systems do not play a role; they are designed for use during the application process rather than for storing chemicals.
