Which dry/solid pesticide formulation consists of particles that are the same weight and shape?

• A. Dust
• B. Pellet
• C. Granule
• D. Tablet

Answer: (C)

Uniform particle size and weight in a dry pesticide formulation helps it flow consistently, mix evenly, and spread predictably during application. Granules are made up of many small particles that are designed to be the same weight and shape, which gives uniform behavior when handling and applying them. Dust, on the other hand, is composed of very small particles that vary in size and shape, leading to inconsistent coverage and more drift. Pellets are larger rounded pieces and treated as single units rather than a bulk of identical particles, so they don’t fit the idea of uniform particles. Tablets are compressed into one solid mass, not a collection of identical particles. So the formulation with particles that are the same weight and shape is granules.
