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

Applying pesticides during the early morning or evening is beneficial primarily because wind speed tends to be lower and humidity is higher during these times. Lower wind speeds help reduce the risk of drift, which can lead to pesticide being carried away from the intended target area. This is crucial for ensuring that the pesticide effectively reaches its target without affecting non-target organisms or environmental areas that should not be treated.

Increased humidity can also enhance the efficacy of the pesticide application. Higher humidity levels can reduce evaporation rates, allowing the pesticide to remain active longer in the area applied. This might lead to better absorption by the plants or target pests, resulting in more effective pest management.

Although sunlight intensity and insect activity can influence the timing of pesticide applications, the primary factors that make early morning or evening advantageous for application are the combination of lower wind speeds and higher humidity levels, which optimize both safety and effectiveness.
