Pesticide drift is primarily caused by movement of the chemical by ____________.

Pesticide drift is primarily caused by movement of the chemical by ____________.

• A. evaporation
• B. runoff
• C. leaching
• D. wind or air currents

Answer: (D)

Pesticide drift happens when the sprayed chemical is carried through the air to locations away from where you intended to apply it. The main factor moving it is wind or air currents, which push and transport airborne droplets or vapors. Evaporation describes a change from liquid to vapor and can affect how long droplets stay airborne, but the actual movement is driven by air flow. Runoff and leaching involve water movement on the surface or through soil, not movement through the air. So the primary cause is wind or air currents.
