What must be included if the pesticide application is made outdoors?

When a pesticide application is made outdoors, it is critical to include wind direction, speed, and temperature in the documentation. These factors significantly influence the application’s effectiveness and its potential impact on the surrounding environment. For instance, wind direction and speed can affect how far the pesticide may drift from the intended target, which is particularly important to avoid unintended harm to non-target plants, animals, or humans. Temperature can also affect pesticide volatility and efficacy—certain chemicals may be more potent or prone to evaporation at higher temperatures, which necessitates careful consideration in outdoor applications.

While the other options may pertain to the application process in some contexts, they do not directly relate to the environmental safety and efficacy of the pesticide application in the same critical manner as the meteorological conditions do.
