MDARD Michigan Core Pesticide Applicator Practice Exam

Which of the following is considered a misuse of a pesticide?

1. Treating for a pest noted on the label

2. Using a pesticide at a recommended dosage

3. Using a pesticide at a lower dosage but more frequently than prescribed

4. Using a pesticide at a recommended frequency

The correct answer is: Using a pesticide at a lower dosage but more frequently than prescribed

Using a pesticide at a lower dosage but more frequently than prescribed can be considered a misuse because it does not adhere to the guidelines established on the pesticide's label. Pesticide labels are designed to provide specific dosage and frequency recommendations based on extensive testing and regulatory approval to ensure both effectiveness and safety. When a user opts to apply a pesticide at a frequency that exceeds the recommendations, even if the individual doses are lower, it can lead to increased risks of harm to non-target organisms, resistance development in pests, and potential environmental contamination. This practice may also compromise the effectiveness of the pesticide, as pests could become accustomed to lower levels of the active ingredient, making them harder to control over time. Adhering strictly to the label instructions for both dosage and application frequency is critical in responsible pesticide use, which promotes not only effective pest control but also protects human health and the environment.
