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

• A. Granules
• B. Pellets
• C. Dust
• D. Wettable powders

Answer: (B)

Uniform particle size and shape ensure even distribution and predictable performance in the field. Pellets are formed into discrete, identical units—each particle having the same weight and shape—so when you apply them, they spread and release consistently, giving uniform coverage and dose. Dust and wettable powders consist of many tiny particles with varying sizes and shapes, which leads to uneven mixing, dispersion, and coverage. Granules are larger particles and can be fairly uniform, but the explicit uniformity in weight and shape is most characteristic of pellets.
