§ 180.345 Ethofumesate; tolerances for residues.
(a) General. Tolerance are established for residues of the herbicide ethofumesate, including its metabolites and degradates, in or on the commodities in the table below. Compliance with the tolerance levels specified below is to be determined by measuring only the sum of ethofumesate, 2-ethoxy-2,3-dihydro-3,3-dimethyl-5-benzofuranyl methanesulfonate, and its metabolites 2-hydroxy-2,3-dihydro-3,3-dimethyl-5-benzofuranyl methanesulfonate, and 2,3-dihydro-3,3-dimethyl-2-oxo-5-benzofuranylmethanesulfonate, calculated as the stoichiometric equivalent of ethofumesate, in or on the following food commodities.
| Commodity | Parts per million |
|---|---|
| Beet, garden, leaves | 5 |
| Beet, garden, roots | 0.5 |
| Beet, sugar, molasses | 2 |
| Beet, sugar, roots | 1.5 |
| Beet, sugar, tops 1 | 4 |
| Cattle, fat | 0.05 |
| Cattle, meat | 0.05 |
| Cattle, meat byproducts | 0.05 |
| Garlic, bulb | 0.25 |
| Goat, fat | 0.05 |
| Goat, meat | 0.05 |
| Goat, meat byproducts | 0.05 |
| Grass, forage, fodder and hay, group 17, straw | 1 |
| Horse, fat | 0.05 |
| Horse, meat | 0.05 |
| Horse, meat byproducts | 0.05 |
| Onion, bulb | 0.25 |
| Shallot, bulb | 0.25 |
| Shallot, fresh leaves | 0.25 |
| Sheep, fat | 0.05 |
| Sheep, meat | 0.05 |
| Sheep, meat byproducts | 0.05 |
| 1 This tolerance expires on October 19, 2026. |
(b) Section 18 emergency exemptions. [Reserved]
(c) Tolerances with regional registrations. Tolerances with a regional registration, as defined in § 180.1(l) are established for residues of the herbicide ethofumesate, including its metabolites and degradates, in or on the commodities in the table below. Compliance with the tolerance levels specified is to be determined by measuring only the sum of ethofumesate, 2-ethoxy-2,3-dihydro-3,3-dimethyl-5-benzofuranyl methanesulfonate, and its metabolites 2-hydroxy-2,3-dihydro-3,3-dimethyl-5-benzofuranyl methanesulfonate, and 2,3-dihydro-3,3-dimethyl-2-oxo-5-benzofuranylmethanesulfonate, calculated as the stoichiometric equivalent of ethofumesate, in or on the raw agricultural commodities.
| Commodity | Parts per
million |
|---|---|
| Carrot, roots | 7 |
(d) Indirect or inadvertent residues. Tolerances are established for the combined indirect or inadvertent residues of the herbicide ethofumesate, including its metabolites and degradates, in or on the commodities in Table 3 to this paragraph (d). Compliance with the tolerance levels specified in Table 3 to this paragraph (d) is to be determined by measuring only the sum of ethofumesate, 2-ethoxy-2,3-dihydro-3,3-dimethyl-5-benzofuranyl methanesulfonate, and its metabolites 2-hydroxy-2,3-dihydro-3,3-dimethyl-5-benzofuranyl methanesulfonate, and 2,3-dihydro-3,3-dimethyl-2-oxo-5-benzofuranylmethanesulfonate, calculated as the stoichiometric equivalent of ethofumesate, in or on the commodity.
| Commodity | Parts per million |
|---|---|
| Animal feed, nongrass, group 18 | 1.5 |
| Grain, cereal, forage, hay, stover, and straw, group 16-22 | 1.5 |
| Vegetable, legume, forage and hay, group 7-22 | 0.5 |
