                  Subpart D_Exemptions From Tolerances
 
Sec. 180.1122  Inert ingredients of semiochemical dispensers; exemptions 
from the requirement of a tolerance.

    (a) All inert ingredients of semiochemical dispenser products 
formulated with, and/or contained in, dispensers made of polymeric 
matrix materials (including the monomers, plasticizers, dispersing 
agents, antioxidants, UV protectants, stabilizers, and other inert 
ingredients) are exempted from the requirement of a tolerance when used 
as carriers in pesticide formulations for application to growing crops 
only. These dispensers shall conform to the following specifications:
    (1) Exposure must be limited to inadvertent physical contact only. 
The design of the dispenser must be such as to preclude any 
contamination by its components of the raw agricultural commodity (RAC) 
or processed foods/feeds derived from the commodity by virtue of its 
proximity to the RAC or as a result of its physical size.
    (2) The dispensers must be applied discretely. This exemption does 
not apply to components of semiochemical formulations applied in a 
broadcast manner either to a crop field plot or to individual plants.
    (b) A semiochemical dispenser is a single enclosed or semi-enclosed 
unit that releases semiochemical(s) into the

[[Page 565]]

surrounding atmosphere via volatilization and is applied in a manner to 
provide discrete application of the semiochemical(s) into the 
environment.
    (c) Semiochemicals are chemicals that are emitted by plants or 
animals and modify the behavior of receiving organisms. These chemicals 
must be naturally occurring or substantially identical to naturally 
occurring semiochemicals.
