Wisconsin Pesticide Applicator Practice Test

Applicators of "restricted" use pesticides must keep records for two years of what?

1. Common name of the pesticide

2. Location and size of the area treated

3. Manufacturer of the pesticide

4. Weather conditions during application

The correct answer is: Location and size of the area treated

Keeping records for two years of the location and size of the area treated is essential for applicators of "restricted" use pesticides because it supports compliance with regulatory requirements. This information helps ensure that pesticides are applied correctly and responsibly, allowing for effective tracking of pesticide use and potential environmental impact. Documenting the specific location enables regulators to track the use of hazardous materials in proximity to sensitive areas, while knowing the size of the area treated helps in determining the appropriate application rates and ensures that the pesticide is used within allowable limits. Accurate records also assist in any investigations related to pesticide misuse or environmental contamination. While the common name of the pesticide, the manufacturer, and weather conditions during application are valuable pieces of information, the requirement to keep detailed records of the location and size highlights the importance of accountability in pesticide application practices.
