What list represents the common liquid formulations?

• A. Water soluble concentrate (WS), emulsifiable concentrate (EC), liquid suspension (L)
• B. Wettable powders, granules, WDG-DF
• C. Oil solubles, invert emulsions, SP
• D. Dry flowables, WDG-DF, G

Answer: (A)

The concept here is distinguishing which pesticide formulations are liquids. Water soluble concentrate dissolves completely in water to form a solution, making it a true liquid formulation for spraying. Emulsifiable concentrate is a liquid that, when mixed with water, forms a stable emulsion, also a liquid form used in spray tanks. Liquid suspension is itself a liquid with the active ingredient suspended in a carrier liquid, requiring agitation to keep the suspension uniform but applied as a liquid spray. These three are commonly used liquid formulations because they directly mix with water to create spray solutions or stable sprays.

The other options describe dry or solid forms: wettable powders and granules are solid powders/granules that require wetting or dispersion; WDG-DF is a water-dispersible granular solid; SP (soluble powder) is a dry powder, and G stands for granules.
