What is the formulation that consists of active ingredients placed on a carrier such as clay and then suspended in a small amount of liquid?

• A. Flowable
• B. Granular
• C. Soluble powder
• D. Wettable powder

Answer: (A)

Flowable formulations are suspensions of finely divided solid pesticide particles in a small amount of liquid. The active ingredient is carried on a solid carrier, such as clay, and kept in suspension rather than existing as a dry powder. When you’re ready to use it, you mix with water to achieve the desired spray concentration, shaking as needed to re-suspend any settled particles. This matches the description of placing the active ingredient on a carrier and suspending it in a small amount of liquid.

Granular products are dry particles applied directly; soluble powders dissolve to form a solution in water; wettable powders are dry powders that disperse in water to form a suspension but start as a dry powder rather than being carried on a carrier in a small liquid.
