Oklahoma Applicators License Core Practice Exam

Why is calibration of pesticide application equipment necessary?

1. To ensure faster application

2. To maximize pesticide residues

3. To ensure the correct amount is released to the target site

4. To minimize costs

The correct answer is: To ensure the correct amount is released to the target site

Calibration of pesticide application equipment is essential for ensuring that the correct amount of pesticide is released to the target site. This process involves adjusting and setting the application equipment so that it disperses the pesticide uniformly and at the intended rate. Proper calibration helps to optimize efficacy, ensuring that the pesticide effectively controls the target pest while minimizing potential harm to beneficial organisms, non-target plants, and the environment. When equipment is calibrated correctly, it allows for accurate application rates, which is crucial for achieving the desired pest control results. Over-application can lead to increased pesticide residues, potential harm to the ecosystem, and may contribute to pesticide resistance. Conversely, under-application may result in inadequate pest control, leading to economic losses. Therefore, effective calibration directly supports responsible pesticide use and environmental stewardship.
