Wisconsin Pesticide Applicator Practice Test

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

1. All of the above

2. Location and size of the area treated

3. Manufacturer of the pesticide

4. Weather conditions during application

The correct answer is: All of the above

The requirement for applicators of "restricted" use pesticides to keep records for two years encompasses a comprehensive set of information that ensures accountability and safety. These records are crucial for regulatory compliance and to contribute to safe pesticide usage practices. Keeping records of the location and size of the area treated is essential because it helps track where pesticides have been applied, which is important for environmental assessments and for managing any potential pesticide drift or contamination in sensitive areas. Documenting the manufacturer of the pesticide used allows for traceability in case of any adverse effects, providing a clear understanding of the specific products applied and facilitating communication with the manufacturer regarding safety data or incident reports. Recording weather conditions during the application is critical for several reasons. Weather can significantly influence pesticide effectiveness and the potential for off-target movement. For example, wind speed and direction can cause drift, while temperature and humidity can affect volatility or evaporation of the pesticide. This information assists in evaluating the conditions under which the pesticide was applied and determining if those conditions were appropriate. By requiring all of this information to be recorded, regulators can better ensure that pesticides are used safely and responsibly, helping to protect not only the environment but also human health.
