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

Suspensions are pesticide mixtures that consist of fine particles dispersed in a liquid, but they are not dissolved in that liquid. This characteristic sets suspensions apart from solutions, where the solute completely dissolves in the solvent. In a suspension, the solid particles are typically heavier than the liquid and can settle out over time if not agitated, necessitating some form of mixing before application to ensure even distribution.

Emulsions refer specifically to mixtures of two immiscible liquids, often oil and water, stabilized by emulsifiers, rather than fine particles. Solutions represent a uniform mixture where one substance is fully dissolved in another, resulting in a clear liquid. Concentrates are preparations that contain a higher concentration of the active ingredient, which may require dilution before use but do not specifically define the type of dispersion of particles.
