Which pesticide formulation consists of finely ground particles?

• A. Granule
• B. Liquid
• C. Dust
• D. Emulsion

Answer: (C)

The correct answer is that a dust formulation consists of finely ground particles. This formulation typically contains active ingredients that are mixed with inert materials to create a dry, free-flowing powder. Dusts are designed to be applied directly onto surfaces where pests may be present, allowing for the active ingredient to remain effective for a prolonged period. The small particle size increases the surface area of the active ingredient, enhancing its effectiveness against pests. In contrast, granules are larger, pellet-like formulations that are also used for pest control but have a different mode of action and application method. Liquid formulations involve active ingredients dissolved in a solvent or carrier, which are typically used for spraying rather than direct dry application. Emulsions consist of mixtures of oil and water, where the active ingredient is suspended in the liquid, and they require agitation before use to maintain a stable mixture. Each of these formulations has specific properties and applications, but dusts are uniquely characterized by their finely ground particle composition.
