What document must a pesticide applicator maintain while applying pesticides?

A pesticide applicator is required to maintain a record of all pesticide applications made to ensure compliance with regulations and promote responsible pesticide use. This documentation serves multiple purposes: it provides a clear history of pesticide usage, helps in tracking application rates, and can assist in integrated pest management strategies. Maintaining accurate application records is also crucial for public safety and environmental protection, as it enables regulators to review practices and assess any potential impact on non-target organisms and the surrounding ecosystem.

The other documents mentioned have their own significance, but they do not fulfill the primary requirement during the application process. A list of stored chemicals and safety data sheets are important for inventory management and safety protocols, but these documents do not specifically pertain to the act of applying pesticides in the moment. A schedule of application times may help with planning but does not serve the purpose of recording applications that have already taken place. Thus, maintaining a record of all pesticide applications is the key requirement for an applicator during their work.
