In what scenario must pesticide use records be maintained for two years?

Maintaining pesticide use records for two years is essential for records of restricted use pesticides. This requirement is in place to ensure compliance with regulatory standards, facilitate tracking of pesticide use, and safeguard public health and the environment.

Restricted use pesticides are those that have been determined by the Environmental Protection Agency (EPA) to pose a potential risk to human health or the environment, and as such, their use is more tightly controlled. Keeping accurate records for this category allows for better oversight and accountability regarding their application. This practice is critical for ensuring that these substances are used in a manner consistent with safety guidelines and labeling instructions.

In contrast, general applications of all pesticides, commercial applications, and record-keeping only when requested by clients do not have the same stringent record-keeping requirements as those for restricted use pesticides. The focus on the need for thorough documentation for restricted use pesticides reflects higher safety concerns associated with their usage.
