Which description best explains a DF/WDG formulation?

• A. They are dry flowables that disperse in water to form a suspension.
• B. They form a suspension in water.
• C. They are dry granules that do not dissolve in water.
• D. They are heavy liquids used for emulsions.

Answer: (C)

DF/WDG formulations are dry, solid pesticide forms designed to be mixed with water to spray. They do not dissolve in water. Instead, the solid particles—granules or fine powders—disperse and stay suspended in the water, forming a uniform suspension for spraying. This makes the description of dry granules that do not dissolve in water the best fit, because it emphasizes their solid, non-dissolving nature while acknowledging they must be dispersed in water to work. The other descriptions either imply a true solution or involve liquids and emulsions, which don’t apply to DF/WDG materials.
