What is required on the pesticide sign posted on a treated property according to Rule 23?

The requirement for signage on a treated property is designed to ensure that individuals are informed about the chemical treatments that have taken place. The correct answer specifies that the sign must include the chemicals applied, the applicator's number, and the date of application. This information is crucial for several reasons:

1. Transparency: Listing the chemicals applied allows anyone on or near the property to know what substances were used, which is particularly important for individuals who may have sensitivities or concerns about certain pesticides.

2. Accountability: Including the applicator's number helps identify who performed the application. This is vital for regulatory oversight and for property owners or residents who may need to follow up regarding the application.

3. Safety Timing: Providing the date of application informs people of when the treatment occurred. This helps individuals understand how long they should be cautious regarding potential exposure or re-entry into the area after treatment.

While details about the pesticide's risks are important for safety and handling, the specific information required by Rule 23 focuses on what was applied, who applied it, and when, rather than providing a detailed risk assessment or the exact quantity used.
