What is the name of a pesticide formulation that consists of finely ground solid particles suspended in a liquid?

A pesticide formulation that consists of finely ground solid particles suspended in a liquid is correctly identified as a "Flowable." Flowable formulations typically involve a viscous liquid that helps maintain the suspension of solid particles, allowing for easy application through standard spraying equipment. This type of formulation is particularly advantageous because it can be easily mixed with water and applied as a liquid, ensuring uniform distribution and effectiveness of the pesticide.

While "Dust," "Granular," and "Wettable powder" are all types of pesticide formulations, they do not fit the description provided in the question. Dusts are typically dry formulations that consist of finely comminuted particles that can be applied in a dry form. Granular formulations consist of larger particles that are often used for applications in soil or on the ground rather than being dissolved in a liquid. Wettable powders do require mixing with water to create a suspension, but they involve particles that are not inherently designed to remain suspended without agitation and may need further mixing to achieve homogeneity. In comparison, flowable formulations are specifically designed to be stable in their liquid state for effective application.
