plant commodity, the property operator must display all of the following information at a central location:

  • identification of the treated area

  • the time and date of the pesticide application

  • the restricted-entry interval

  • the product name, the EPA registration number, and the active ingredients

The information must be displayed when employees work within 1/4 mile of a treated field, and it must remain displayed until the area no longer meets the definition of a treated field or employees are no longer on the establishment, whichever occurs first. (See the Glossary for the definition of a treated field.)

Fieldwork During Pesticide Applica- tion. On farms or in forests, only the people making the application can be directed or allowed to enter or remain in a treated area.

In treated nurseries and greenhouses, only the people making the application can be directed or allowed to enter or remain in a treated area. The treated area boundaries of different sorts of nursery and greenhouse pesticide applications are described below.

If the pesticide is applied in a nursery

  • by aircraft, in an upward direction, or at a pressure of more than 150 pounds per square inch, or is applied as a fumigant, smoke, fog, or aerosol, the prohibited area is the treatment site plus 100 feet in all directions within the confines of the property

  • by ground, in a downward direc- tion from a height greater than 12 inches from the soil or other planting medium, as a fine spray, or using pressure of more than 40 pounds per square inch, but not more than 150 pounds per square inch, or that requires respiratory protection on the product label, the prohibited area is the treatment

site plus 25 feet in all directions within the confines of the property If the pesticide is applied in a greenhouse

  • as a space treatment with a fumigant, smoke, fog, aerosol, or mist or is a pesticide for which the product label requires respiratory protection, the prohibited area is the entire enclosed area plus any adjacent area that is not sealed sufficiently to prevent pesticide transfer from the treatment site, until the ventilation criteria have been met

  • as a spray from a height greater than 12 inches from the soil or other planting medium, as a fine spray, or using a pressure of more than 40 pounds per square inch, the prohibited area is the treatment site plus 25 feet in all directions within the enclosed area

Otherwise, in both the nurseries and greenhouses, the prohibited area is the treatment site.

Greenhouse Ventilation Criteria. When a greenhouse application involves a pesticide with label direc- tions that require respiratory protec- tion, or when any pesticide is applied as a fumigant, smoke, mist, fog, or aerosol, the greenhouse must be ventilated until:

  • the concentration is measured and found not to exceed any pesticide label standard OR

  • one of the following has occurred if there is no label standard:

    • A.

      ten air exchanges are complete

    • B.

      two hours of mechanical ventilation

    • C.

      four hours of passive ventila- tion

    • D.

      twenty-four hours, with no ventilation

    • E.

      any combination of percentage portions of A, B, C, and D above, the sum of which equals 100%
