True or False: It is best to apply pesticide dust during midday when there is a breeze.

Applying pesticide dust during midday when there is a breeze is considered unfavorable due to several factors that can affect both the effectiveness of the pesticide and the safety of the application. During midday, temperatures are generally higher, which can lead to a faster evaporation of the active ingredients in the pesticide formulation. This evaporation can reduce the amount of pesticide that actually reaches the intended target, diminishing its effectiveness.

Additionally, applying pesticide dust when there is a breeze can cause drift, where the pesticide is carried away from the targeted application area by the wind. This drift can lead to off-target deposition, which poses risks to non-target organisms, such as beneficial insects, wildlife, and even humans who may be nearby. Ensuring that pesticides are applied under calm conditions—typically early in the morning or later in the afternoon—reduces these risks and enhances the pesticide's efficacy. Therefore, the statement that it is best to apply pesticide dust during midday when there is a breeze is false.
