What must be completed even after pesticide application is finished?

The correct choice emphasizes the importance of clean-up after pesticide application, which is a critical step to ensure safety and environmental protection. Clean-up involves removing any leftover pesticide materials, applying appropriate cleaning methods for equipment, and ensuring that the application area is safe for people, animals, and the surrounding environment. This step is vital to prevent any unintentional exposure to residual pesticides and to maintain compliance with safety regulations.

While disposal of empty containers, recording application notes, and performing safety inspections are also important components of responsible pesticide management, the act of clean-up directly addresses the immediate hazards associated with the application process. It involves actions that mitigate risk and maintain safe conditions following the use of potentially hazardous materials, making it an essential part of integrated pest management practices.
