Name at least two formulations that require agitation.

• A. Wettable powders (WP), dry flowables (DF), and water-dispersible granules (WG, WDG)
• B. Granular formulations only
• C. Emulsifiable concentrates (EC) and solutions
• D. Gaseous formulations only

Answer: (A)

Formulations that need agitation are those that are not fully dissolved in water but must be kept evenly dispersed as a suspension during application. Wettable powders are fine solids that disperse in water but stay suspended rather than dissolve; if you stop stirring, they settle and you’ll get uneven coverage. Dry flowables behave similarly, being particulate and needing mixing to stay evenly distributed in the spray tank. Water-dispersible granules and WG/WDG are granule-based products designed to break apart and disperse in water, so agitation is required to create and maintain a uniform spray suspension. Granular formulations, on the other hand, are typically used as dry granules or in a way that doesn’t rely on keeping them suspended in water, so continuous agitation isn’t a defining requirement. Emulsifiable concentrates and solutions are liquids that mix with water, and while initial mixing is important, they don’t depend on keeping insoluble particles suspended the way the solid-particulate formulations do.
