Which dry formulation characteristic is accurate?

• A. Pellets are uniform in particle weight and shape
• B. Dust is uniform in particle weight and shape
• C. Granules are uniform in particle weight and shape
• D. Tablets are uniform in particle weight and shape

Answer: (A)

Uniform particle weight and shape in a dry formulation are essential for predictable flow through applicators and even deposition on the target area. Pellets are manufactured to a consistent size, weight, and geometry, which means they flow smoothly from hoppers, bridge less often, and spread more evenly when applied. That consistency translates to a more accurate and uniform delivery of the active ingredient across the treated field.

Dusts, on the other hand, typically consist of many tiny particles with a wide range of sizes and densities, which leads to variable flow, greater drift, and uneven coverage. Granules can be fairly uniform, but their consistency isn’t always guaranteed across products, whereas tablets aren’t designed for routine field dispersion and don’t provide the same uniformity in spread.
