WDG and DF are examples of which category of pesticide formulations?

• A. Dry/solid formulations
• B. Liquids
• C. Gases
• D. Emulsifiable concentrates

Answer: (A)

Pesticide formulations are grouped by their physical form into solids, liquids, or gases. WDG and DF are solid, dry forms. WDG stands for water-dispersible granules, which are solid granules that break apart and disperse in water to make a spray. DF stands for dry flowable, which are fine dry particles that readily disperse in water to form a suspension. Because the active ingredient is already in a solid form and only needs mixing with water to apply, these are classified as dry/solid formulations. This differs from liquids like emulsifiable concentrates, which are already liquids that form emulsions in water, or from gases used for fumigation.
