What type of drift refers to vapors moving off target after pesticide application?

The term "vapor drift" specifically describes the phenomenon where pesticide vapors move away from the intended application target. This type of drift occurs when volatile chemicals evaporate and are carried by the wind or air currents, potentially affecting nearby plants, animals, and ecosystems that were not the intended areas for pesticide application. Understanding this concept is crucial for minimizing unintended exposure and environmental impact.

In contrast, particle drift refers to the movement of solid pesticide particles, while soil and water drift do not pertain to vapor movement but rather to the contamination or transport of pesticides in those mediums. Thus, identifying vapor drift as the correct response highlights an awareness of the specific risks associated with airborne pesticide vapors post-application.
