# 180.723 Spiropidion; tolerances for residues.

(a) *General.* (1) Tolerances are established for residues of the insecticide spiropidion, including its metabolites and degradates, in or on the commodities in Table 1 to this paragraph (a)(1). Compliance with the tolerance levels specified in Table 1 to this paragraph (a)(1) is to be determined by measuring only the sum of spiropidion [3-(4-chloro-2,6-dimethyl-phenyl)-8-methoxy-1-methyl-2-oxo-1,8-diazaspiro[4.5]dec-3-en-4-yl ethyl carbonate] and its metabolite SYN547305 [3-(4-chloro-2,6-dimethylphenyl)-4-hydroxy-8-methoxy-1-methyl-1,8-diazaspiro[4.5]dec-3-en-2-one] calculated as the stoichiometric equivalent of spiropidion, in or on the following plant commodities:

Table 1 to Paragraph (**a**)(1)

| Commodity | Parts per
million |
| --- | --- |
| Cucumber | 0.8 |
| Muskmelon | 0.9 |
| Pepper, bell | 1.5 |
| Pepper, nonbell | 1.5 |
| Potato | 1.5 |
| Pumpkin | 0.9 |
| Soybean, seed | 3 |
| Tomato | 0.8 |
| Watermelon | 0.9 |
| There are no U.S. registrations for this commodity as of July 20, 2022. |  |

(2) Tolerances are established for residues of the insecticide spiropidion, including its metabolites and degradates, in or on the commodities in Table 2 to this paragraph (a)(2). Compliance with the tolerance levels specified in Table 2 to this paragraph (a)(2) is to be determined by measuring only SYN547305 [3-(4-chloro-2,6-dimethylphenyl)-4-hydroxy-8-methoxy-1-methyl-1,8-diazaspiro[4.5]dec-3-en-2-one] calculated as the stoichiometric equivalent of spiropidion, in or on the following livestock commodities:

Table 2 to Paragraph (**a**)(2)

| Commodity | Parts per
million |
| --- | --- |
| Cattle, fat | 0.03 |
| Cattle, meat byproducts | 0.3 |
| Goat, fat | 0.03 |
| Goat, meat byproducts | 0.3 |
| Horse, fat | 0.03 |
| Horse, meat byproducts | 0.3 |
| Sheep, fat | 0.03 |
| Sheep, meat byproducts | 0.3 |
| There are no U.S. registrations for this commodity as of July 20, 2022. |  |
