Which of the following can lead to unnecessary pesticide safety risks?

Ignoring prevailing weather during pesticide application can significantly increase safety risks for both applicators and the environment. Weather conditions such as wind speed and direction, temperature, and humidity play a crucial role in the effectiveness and safety of pesticide application. For instance, applying pesticides on a windy day can lead to drift, where pesticides are carried away from the target area, potentially contaminating non-target areas, harming beneficial organisms, or posing risks to humans and wildlife.

Additionally, adverse weather conditions may affect how pesticides evaporate or degrade, further complicating their behavior in the environment. By neglecting to consider these factors, applicators may inadvertently expose themselves and others to higher levels of pesticides than intended and reduce the efficacy of the pest control measures they are attempting to implement. This highlights the importance of incorporating weather considerations into the pesticide application process to mitigate risks and ensure safety.
