Which of the following is a recommended practice when dealing with low humidity and high temperatures?

In situations of low humidity and high temperatures, avoiding pesticide applications is recommended because these conditions can significantly affect the efficacy and safety of pesticide treatments. High temperatures can increase evaporation rates, leading to reduced effectiveness as the pesticide might evaporate before it has a chance to adhere to the intended target. Additionally, low humidity can lead to further evaporation and can also impact how well the pesticide spreads or penetrates the target area.

When pesticides are applied under these extreme conditions, there's a risk of drift, which is the unintended movement of pesticides away from the target area. This can increase environmental contamination and may pose risks to non-target organisms. Furthermore, applying pesticides during hot and dry conditions can lead to rapid degradation of some active ingredients, diminishing their potential effectiveness. Therefore, it’s best to wait for more favorable weather conditions to ensure successful pesticide application and minimize risks to both human health and the environment.
