(a) General.
(1)
Time-limited tolerances are established for combined residues of 2,6-DIPN, including its metabolites and degradates, in or on the commodities in the table below as a result of the post-harvest application of 2,6-DIPN to potatoes, when 2,6-DIPN is used in accordance with good agricultural practices. Compliance with the tolerance levels specified below is to be determined by measuring only 2,6-DIPN in or on the commodities.
| Commodity | Parts per million | Expiration/revocation date |
|---|---|---|
| Potato, granules/flakes | 5.5 | 5/18/12 |
| Potato, wet peel | 6.0 | 5/18/12 |
