Which of the following is NOT required to be posted on a treated property under Rule 23?

The requirement for posting information on a treated property is aimed at ensuring safety and transparency for those who may come into contact with the area after pesticide application. According to Rule 23, certain critical details must be made available to the public. This includes the name of the pesticide used, which enables individuals to identify the specific chemical involved and understand any potential hazards it may pose.

Additionally, the applicator's phone number is essential as it provides a direct line of communication for inquiries about the treatment, allowing residents or passersby to ask questions or express concerns regarding safety or follow-up actions. The date of application is also a vital piece of information, as it indicates when the treatment occurred and helps determine when it is safe to re-enter the area or resume normal activities.

In contrast, the customer's address is not required to be posted. While it might offer some context about the location of the application, confidentiality and privacy considerations typically prevent the address from being made publicly available. Thus, keeping this information private helps protect the customer's identity and personal information while still providing essential safety details to the public.
