What is most likely to occur if a pilot starts spraying too early while descending into a field?

The choice of off-target application arises from the fact that descending too early while spraying can lead to several issues. When a pilot initiates spraying before reaching the appropriate height and speed, the spray does not distribute evenly or accurately. This premature spraying can result in the pesticide or fertilizer being released in unintended areas, such as near water bodies, residences, or non-target crops, which can harm the environment and reduce the effectiveness of the application.

Safe and effective aerial application relies on specific altitude and speed that ensure the material reaches the intended target. If sprayed from too high, the droplets may disperse too widely, and if sprayed too low, the droplets might be affected by wind turbulence or other environmental factors, leading to off-target drift. Therefore, timing and height are critical in ensuring that the application is both effective and environmentally responsible, making off-target application the most likely consequence of an early descent.
