What risk is associated with applying pesticides at the wrong time of day?

Applying pesticides at the wrong time of day can lead to increased evaporation and drift, which poses significant risks to both the efficacy of the application and the surrounding environment or non-target areas. During hotter parts of the day, typically mid-afternoon, the temperatures are higher and humidity levels lower. This can cause the pesticides to evaporate more rapidly, reducing their ability to effectively target the desired pests.

Moreover, increased temperatures and winds can lead to drift, where pesticide particles are carried away from the intended application site, potentially affecting nearby crops, wildlife, water sources, and residential areas. This not only undermines the application’s effectiveness but also raises concerns about safety and compliance with agricultural regulations.

In contrast, making applications during cooler times, such as early morning or late evening, can significantly lower these risks, enhancing the overall success of pest management strategies while protecting the environment.
