Under what circumstances is a certified applicator required to be physically present at the application site?

A certified applicator is required to be physically present at the application site when state law or the product label specifies this requirement. Many pesticides have specific regulations that dictate the level of supervision necessary during their application, depending on the potential risks involved. These rules are often in place to ensure that safety measures are followed correctly, which can include observing the application closely to prevent drift, runoff, or unintended exposure to people and pets.

Product labels are legally binding documents that provide important instructions about how to use the pesticide safely and effectively, including details about usage conditions, required safety equipment, and application methods. If the label indicates that the applicator must be physically present, compliance with that requirement is essential for both regulatory adherence and the protection of human health and the environment.

While factors like weather conditions, urban areas, or the toxicity of materials might influence the management of the application process, they do not independently necessitate the presence of a certified applicator as much as the law or label does.
