What information must be collected and maintained for RUP sales?

The requirement to collect and maintain specific information for Restricted Use Pesticide (RUP) sales is primarily concerned with ensuring accountability and traceability in the distribution of these potentially hazardous substances. The correct choice involves gathering the name and address of both the dealer and the purchaser, in addition to the quantity sold.

Understanding the necessity of this information is crucial. The name and address of the dealer and purchaser help regulatory bodies trace transactions and ensure that pesticides are being sold in compliance with laws designed to protect public health and the environment. Furthermore, maintaining records of the quantity sold is essential for monitoring usage patterns and ensuring that sales are appropriate to the purchaser's authorized use of RUPs.

Other choices do not encompass a comprehensive record-keeping requirement. For instance, capturing only the name of the pesticide or the quantity sold without purchaser identification fails to provide sufficient data to track how these substances are distributed and to whom. This lack of detail could undermine efforts to enforce safety regulations and effective pesticide management practices.
