Which form describes finely ground chemicals that may be mixed with diluents and are used with limited use due to hazards of drift and high cost?

• A. Dusts
• B. Granules
• C. Surfactant
• D. A sticker

Answer: (A)

Finely ground pesticide products are described as dusts. Their powdery form makes them easy to mix with a diluent to reach the desired application concentration, but the same fine particles can readily drift with air currents, leading to off-target movement. That drift risk is a major reason their use is limited and tightly controlled, since protecting non-target areas and people adds to handling precautions and regulatory constraints. The cost aspect often comes from the need for careful, targeted application and the extra measures required to manage drift, which can make dust applications more expensive per area treated. Granules are larger and stay closer to the application area, so drift is less of a concern; surfactants and stickers are not the primary pesticide forms themselves but adjuvants that modify spreading or sticking properties.
