Which of the following describes a dry formulation with standardized particle size and shape?

• A. Suspension
• B. Dust
• C. Granule
• D. Emulsifiable concentrate

Answer: (C)

A dry formulation with standardized particle size and shape is a granule. Granules are created by binding or agglomerating fine particles into larger, uniform units, which gives a consistent size and shape and keeps the formulation dry. This uniformity helps ensure even distribution, accurate dosing, and reduced drift during application, which are all important for effective pest control.

A suspension is a liquid with solid particles dispersed in it, so it’s not dry. A dust is a dry powder, but it’s usually very fine and lacks consistent particle size and shape, making standardization and controlled application harder. An emulsifiable concentrate is also a liquid that forms an emulsion in water, not a dry granule.
