Which quality is characteristic of dry granules in pesticide formulations?

• A. High volatility
• B. Uniform particle size and shape
• C. Rapid dissolution in water
• D. Low bulk density

Answer: (B)

Uniform particle size and shape in dry granules affects how evenly the product flows, packs, and is distributed during application. When granules are uniform, they flow smoothly through hoppers and spreaders, mix consistently with other ingredients, and deliver a predictable, even coating on the target area. This reduces segregation of fines and coarse particles, minimizes clogging and dust, and ensures a consistent dose from batch to batch. High volatility would cause loss of the active ingredient, rapid dissolution in water would change how the product behaves in the spray, and low bulk density would hinder handling and dosing, making uniform size and shape the defining quality for dry granules.
