What is the term for the pesticide formulation process where solid particles are dispersed in a liquid?

The correct answer is the term that describes the process of dispersing solid particles in a liquid, which is known as suspension. In a suspension, solid particles are evenly dispersed throughout a liquid, allowing them to remain suspended and not settle out over time. This type of formulation is crucial in pesticide application as it helps ensure that the active ingredients remain uniformly distributed, providing effective control of pests when sprayed.

In contrast, emulsification refers to the process of mixing two immiscible liquids, where one liquid is dispersed in another, often with the help of an emulsifier. Granulation involves forming solid particles from powders by agglomerating them into granules, which is a different process entirely and typically pertains to production methods for solid formulations. A solution involves a homogenous mixture where solutes are completely dissolved in solvents, unlike suspensions where the solid particles remain distinct and can eventually settle.
