What would be considered a no contact activity in a pesticide-treated area in which the REI has not expired?

Operating a tractor from an enclosed cab is considered a no contact activity in a pesticide-treated area while the Restricted Entry Interval (REI) has not expired. During the REI, there are specific activities that are permissible without coming into contact with treated surfaces, and operating machinery like a tractor from an enclosed cab falls into this category. The enclosed nature of the cab provides a barrier between the operator and the treated area, thereby preventing direct exposure to pesticide residues.

In contrast, hand-pulling weeds would involve direct interaction with the ground and potentially with the pesticide residue, which is not allowed during the REI. Inspecting plants closely also means coming into contact with those plants potentially treated with pesticides, violating the no contact rule. Distributing fliers about pest management, while seemingly benign, does not fall under activities that specifically allow for no contact with treated surfaces as it may still lead to exposure depending on where the distribution occurs relative to the treated area. Thus, option B is the only choice that meets the criteria for no contact activity.
