Public Health Pest Control Practice Exam 2025 – Complete Prep Guide

The term "carrier" in pesticide use specifically refers to the primary material that is used to disperse the active ingredient of the pesticide. Carriers are important because they help in applying the pesticide effectively to the target area, ensuring that the active ingredient is delivered in a usable form. Carriers can include various substances such as water, oils, or solvents that enhance the spread and coverage of the pesticide on the surface or organism being treated.

Understanding the role of the carrier is crucial for achieving optimal efficacy of the pesticide application, as it influences how well the active ingredients adhere to and penetrate the target area, potentially improving the effectiveness of pest control measures. In contrast, methods of application, specific pesticide formulations, and spraying equipment pertain to different aspects of pesticide application and do not define what a carrier is.
