What is one way pesticides can move from an application area?

Pesticides can volatilize, which means they can change from a liquid or solid form into a gas or vapor. This process can occur post-application, particularly when temperatures rise or the pesticide formulation is sensitive to evaporation. When pesticides volatilize, they can be carried away by air currents, potentially impacting areas beyond the originally targeted applications. Understanding this movement is crucial for effective pest management and minimizing unintended environmental impacts.

The other options do not pertain directly to the movement of pesticides from an application area. Storing pesticides in impermeable containers prevents movement and leakage but does not address post-application scenarios. Applying pesticides during heavy rains can lead to runoff into water bodies but does not describe their movement as a result of physical processes like volatilization. Lastly, using biodegradable options may influence the breakdown of pesticides but does not directly relate to the process of movement from where they were applied.
