Which formulation often contains up to 90% AI by weight and is delivered as granules?

• A. WDG/DF
• B. Wettable Powders
• C. Dusts
• D. EC

Answer: (A)

Granular formulations that carry a very high portion of the active ingredient are designed for potency and ease of handling. Water Dispersible Granules (WDG) and Dry Flowables (DF) are made as granules so you can pack a large amount of AI into each particle. Because of this granule structure, these products can contain up to about 90% active ingredient by weight, with the remaining portion being inert material that provides bulk, flow, and helps dispersion in water. When you mix a WDG or DF in water, the granules break apart and release the active ingredient to form a uniform suspension or solution for application. This high AI content means you apply less product to achieve the same effect, and the granules help reduce dust and improve handling compared with powders. Wettable powders are actual powders that form suspensions but are not granules and can be quite dusty. Dusts are also powders, not granules. Emulsifiable concentrates are liquids you dilute in water, not granules. So the granule-based option with the very high AI load is the Water Dispersible Granules or Dry Flowables.
