Oregon Pesticide Practice Test

Which best management practice will help prevent contamination of surface water and ground water by pesticides?

1. Applying pesticides during the day

2. Following IPM principles

3. Using less water for application

4. Storing pesticides in open containers

The correct answer is: Following IPM principles

Following Integrated Pest Management (IPM) principles is a best management practice that significantly contributes to the prevention of pesticide contamination in both surface water and groundwater. IPM emphasizes a holistic approach to pest control that integrates various methods designed to minimize environmental impact, reduce pesticide reliance, and promote sustainable agricultural practices. By utilizing IPM, practitioners assess pest populations and determine the best control strategies that may include cultural, biological, mechanical, and chemical methods. This multifaceted approach allows for more efficient use of pesticides, ensuring they are only applied when absolutely necessary and in a manner that minimizes the risk of runoff or leaching into water sources. Additionally, IPM encourages careful timing and placement of pesticide applications, reducing the likelihood of unintended contamination. In contrast, applying pesticides during the day without consideration of environmental factors, using less water for application might not adequately dilute pesticides to reduce runoff, and storing pesticides in open containers increases the risk of spills and contamination. Implementing IPM strategies helps to address these concerns systematically, fostering better environmental stewardship and public health protection.
