What is an important consideration when applying pesticides regarding weather conditions?

Wind speed is a critical consideration when applying pesticides because high winds can lead to drift, where the pesticide does not reach the intended target area and affects unintended plants, animals, or water sources. Accurate application relies on an optimal environment that keeps the pesticide where it needs to be for effective treatment. Low wind speeds help ensure that the product remains concentrated on the targeted infestation rather than being carried away by the breeze.

Furthermore, while the other weather conditions can be influential in various contexts, they do not have the same direct impact on application efficiency and safety as wind speed. For example, rain expected soon after application can wash away the pesticide, reducing effectiveness. Extremely high or low temperatures can also affect the product's stability and efficacy, but managing wind is paramount to prevent unauthorized pesticide dispersal. In contrast, humidity may influence certain applications but isn't universally critical like wind control.
