Which formulation is described as AI impregnated on clay and ground to a fine powder suspended in a small amount of liquid?

• A. Flowables (F)/ Liquids (L)
• B. WDG/DF
• C. Dusts
• D. ULV

Answer: (A)

The concept being tested is how certain pesticide formulations are prepared for spraying. A flowable formulation is a suspension of very fine solids in a liquid, designed to be sprayed after dilution. Here, the active ingredient is attached to a clay carrier, ground into a fine powder, and kept suspended in a small amount of liquid to form a ready-to-spray suspension. This setup matches flowables because the solid particles remain dispersed in liquid, making a stable sprayable product.

Dusts are dry powders used without a liquid carrier. WDG/DF are dry granules that must be dispersed in water to form a suspension. ULV formulations are designed for ultra-low-volume fogging and are typically concentrated liquids, not finely dispersed solids in a small amount of liquid.
