Before you apply a pesticide, what should you always do?

Before applying a pesticide, reading the label is essential because it contains critical information regarding the proper use of the chemical, including safety precautions, application rates, and any specific restrictions or guidelines for that particular product. The label is essentially a legal document that provides detailed instructions designed to ensure effective and safe application.

Understanding the label helps to mitigate risks not only to human health and the environment but also enhances the effectiveness of the application. It contains vital information about personal protective equipment (PPE) requirements, the conditions under which the pesticide can be safely applied, and the appropriate methods for application. Adhering to the label ensures compliance with regulations as well, which is crucial in the pest control industry.

In contrast, the other choices do not align with best practices for pesticide application. For example, disposing of leftover pesticide without proper guidelines could pose environmental hazards. Mixing pesticides without consulting the label can lead to improper dosages or harmful reactions, and purchasing more pesticides than needed may lead to unnecessary waste and increased environmental impact. Therefore, the most responsible and fundamental action before any pesticide use is to thoroughly read and understand the label.
