What conditions may make early morning or evening a good time for application?

The choice indicating that early morning or evening may be good times for pesticide application is based on specific environmental conditions. During these times, wind speed tends to be lower, which minimizes the risk of drift when pesticides are applied. Drift can result in chemicals being carried away from the target area by wind, potentially harming non-target organisms or causing contamination.

Additionally, humidity is often higher during early morning and evening, which can enhance the effectiveness of certain pesticides. Higher humidity levels can help reduce evaporation and prolong the time the pesticide remains active on the target surfaces. This can be particularly beneficial for applications, as it allows for better absorption and effectiveness.

These combined factors of lower wind speed and higher humidity contribute to a safer and more effective application environment for pest control.
