Which formulation requires moderate agitation to keep active ingredients mixed?

The formulation that requires moderate agitation to keep active ingredients mixed is indeed a suspension or flowable. This type of pesticide formulation consists of solid particles that are suspended in a liquid medium. Over time, these solid particles can settle out of the solution due to gravity. To ensure that the active ingredients are evenly distributed and remain effective when applied, moderate agitation is necessary before and during usage.

Suspensions typically require mixing to maintain a uniform consistency and ensure that the application delivers the proper dose of the active ingredient. Unlike true liquids or solutions, where the active ingredients are fully dissolved and do not need mixing, or micro-encapsulated formulations, which are designed to release the active ingredient slowly and do not require constant agitation, suspensions are distinctly characterized by needing regular stirring or mixing. Fumigants, on the other hand, usually exist in a gaseous form, which does not necessitate any mixing or agitation. Thus, suspensions or flowables stand out as formulations that actively demand agitation to maintain effectiveness.
