Is the statement true or false? The airborne movement of pesticide particles from the target area occurs only during application and is clearly visible when it occurs.

The statement is false because airborne movement of pesticide particles can occur not only during application but also after application due to environmental factors such as wind, temperature, and humidity. This means that even if the application is complete, residual particles can still be carried away from the target area by air currents.

Additionally, this movement is not always clearly visible. The dispersion of small pesticide particles may happen at such a fine scale that it cannot be easily seen, especially at distances further from the application site. Visibility can be affected by conditions such as ambient light, particle size, and the characteristics of the pesticide itself. Therefore, it is essential for applicators to consider the potential for drift and off-target movement at all times, not just during the immediate application process.
