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

• A. Pellets
• B. Dust
• C. Granules
• D. Tablets

Answer: (A)

Uniform particle size and shape in a dry pesticide formulation ensure that every particle delivers a consistent amount of active ingredient and behaves the same way when it’s distributed. Pellets are made as identical small units through binding and compression or extrusion, so each particle has the same weight and shape. This uniformity allows spreader settings to yield even coverage and predictable performance, with less drift or clogging and more reliable pest control.

Dust, by contrast, is a mix of very fine particles with a wide range of sizes and shapes, which makes distribution inconsistent. Granules are larger and can vary in size and shape, though they’re discrete particles. Tablets are uniform and compacted solids but are not typically used as a dry, spreadable formulation in field applications.
