What is vapor drift?

  1. Pesticide particles carried away by air currents

  2. Water contamination from soil erosion

  3. Groundwater recharge during rain

  4. Visible pesticide droplets falling to the ground

The correct answer is: Pesticide particles carried away by air currents

Vapor drift refers to the movement of pesticide particles that have become airborne due to air currents. This phenomenon occurs when volatile pesticide formulations evaporate from treated surfaces and are then carried away by wind or other atmospheric conditions. Such drift can result in the unintended application of pesticides to non-target areas, which could lead to environmental contamination and harm to beneficial organisms. Understanding vapor drift is crucial for applicators to ensure they use pesticides responsibly and in compliance with regulations, minimizing the risk of unintended exposure to sensitive areas, such as water bodies, gardens, or neighboring properties.
