Name a reason for using a protective barrier when applying pesticides.

Using a protective barrier when applying pesticides is essential for preventing contamination of non-target areas and safeguarding the applicator. This practice ensures that the pesticide is directed only where it is needed, minimizing the risk of affecting beneficial organisms or surrounding environments that should remain pesticide-free. The barrier acts as a physical shield, reducing drift and runoff, which can lead to unintended exposure in areas where pesticides could be harmful. Additionally, it protects the applicator from direct contact with the chemicals, thereby promoting health and safety during application. This consideration is crucial for both environmental stewardship and the well-being of individuals involved in the pesticide application process.
