What kind of pesticide mixtures consist of fine particles dispersed in a liquid?

Suspensions are pesticide mixtures that consist of fine particles uniformly dispersed in a liquid. In a suspension, these particles do not dissolve but remain suspended within the liquid until they settle over time. This characteristic makes them particularly effective for certain applications, as they can deliver active ingredients more effectively to target pests.

Emulsions refer to mixtures of two immiscible liquids, often oil and water, that require an emulsifying agent to stabilize the mixture. Solutions are homogeneous mixtures where the solute is dissolved completely in the solvent, leading to a clear liquid with no particulate matter. Concentrates typically refer to formulations that contain a high amount of active ingredient, which may need dilution before use, and are not inherently defined by particle suspension.

Thus, suspensions are distinct in that they maintain suspended solid particles within a liquid medium, which is crucial for certain pest management strategies.
