Texas Pesticide Applicator Practice Exam

Which option is a common consequence of pesticide exposure?

1. Higher crop yields

2. Pesticide resistance in pests

3. Injury to humans and animals

4. Decrease in agricultural efficiency

The correct answer is: Injury to humans and animals

Pesticide exposure can lead to injury in both humans and animals, making it a significant concern in agricultural practices. This injury may manifest in a variety of ways, including acute reactions such as skin irritation, respiratory problems, or gastrointestinal issues, as well as chronic health effects over time. The safety of applicators, farmworkers, and nearby communities relies heavily on understanding and mitigating the risks associated with pesticide use. Regarding the other options, while pesticide resistance in pests is a notable consequence of repeated pesticide applications, it reflects how species evolve in response to chemical pressure rather than the immediate effects of exposure. Crop yields can potentially be increased with proper pesticide application, but excessive or improper use can lead to environmental damage, which might diminish yield over time. Likewise, while decreased agricultural efficiency could occur due to negative effects on ecosystem health or resistance development, it is not as direct a consequence of exposure as the potential injury to humans and animals.
