Which formulation is used to minimize drift during application?

• A. Wettable powders
• B. Granules
• C. ULV formulations
• D. Emulsifiable concentrates

Answer: (B)

Drift happens when pesticide moves away from the target area, carried by wind or air currents. Granules are solid, relatively large particles that are applied with a spreader, not sprayed as a fine liquid. Because of their size and weight, they tend to stay near the ground and settle quickly, which greatly reduces the chance of being carried off-target.

In contrast, liquid formulations like ultra-low volume sprays and emulsifiable concentrates produce fine droplets that readily become airborne, increasing drift risk. Wettable powders can also become airborne as dust or droplets during application. So, using granules minimizes drift because their physical form and application method keep the material where it’s supposed to work.
