Which weather condition would generally indicate safe conditions for aerial application of pesticides?

The presence of stable temperature is a significant indicator of safe conditions for aerial application of pesticides. Stable temperatures suggest that there are minimal fluctuations in the air that could lead to unpredictable changes in drift or dispersion of the pesticide. This helps ensure that the pesticide is applied accurately and that it will remain effective on the intended target area without unintended environmental impacts.

In contrast, high winds can lead to increased drift of pesticides, causing them to spread to unintended areas, which can harm non-target crops, wildlife, and even humans. Cumulus clouds might indicate changing weather conditions, such as the potential for thunderstorms, which can complicate or impede aerial application efforts. Rainy weather can wash away pesticides before they have a chance to adhere effectively, reducing their efficacy and impacting the overall treatment plan.

Thus, stable temperature conditions are preferable for ensuring that the pesticide application is both safe and effective.
