What should be avoided during midday pesticide applications to minimize drift?

Choosing to avoid air stability during midday pesticide applications is critical for minimizing drift. Air stability refers to the condition in which the air does not mix well—often seen in early morning or late evening when the air is cooler and less turbulent. When the air is stable, pesticide particles released during application can remain concentrated in the same layer, increasing the chance of drift beyond the intended application area.

In contrast, conditions with good air turbulence help disperse pesticide particles more quickly and evenly, reducing the likelihood of drift. Therefore, applying pesticides during periods of instability, such as when the air is warmer and more dynamic, is a better practice to ensure that the pesticides are delivered effectively to the target area without unintended spread.

The other options do not directly contribute to minimizing drift during midday applications. For instance, low temperatures and high humidity can affect how pesticides interact with the environment, but they do not influence the stability of the air in the same way. Similarly, using low-pressure systems affects the application technique and delivery of pesticides but does not inherently address the drift issue tied to air stability.
