Texas Pesticide Applicator Practice Exam

True or False: A pesticide becomes a pollutant when applied at a higher dose than recommended or when it drifts off target.

1. True

2. False

3. Not applicable

4. Only when it drifts

The correct answer is: True

A pesticide can indeed become a pollutant when it is applied at a higher dose than recommended or when it drifts off target. When applied beyond the recommended dosage, there is an increased risk of residual effects that may harm non-target organisms, contaminate soil and water, or disrupt local ecosystems. Similarly, when pesticides drift away from the intended application area, they can affect nearby crops, wildlife, and even human populations. This unintended dispersion not only impacts the environment but can also breach state and federal regulations regarding chemical use. Both scenarios contribute to the classification of the pesticide as a pollutant, demonstrating the importance of adhering to usage guidelines and being mindful of application techniques to protect public health and the environment.
