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

• A. Bait
• B. Granular
• C. Pellet
• D. Dust

Answer: (C)

Pellet formulations are made by shaping the active ingredient into uniform, compact units so every piece has essentially the same weight and shape. This uniformity comes from extrusion or compression during manufacturing, producing pellets that distribute evenly when applied and deliver a consistent amount of pesticide per unit. In contrast, dusts are fine powders with a wide range of particle sizes and shapes, which can lead to uneven coverage and drift. Granular formulations use larger particles that can vary in weight and geometry, also reducing uniformity. Baits are designed for attraction and may come in various forms, but the defining feature here is the consistent size and mass of the particles, which pellets provide.
