Methoxyfenozide Summary of Analytical Chemistry and Residue Data (Addendum) DP Barcode D429009 

This addendum to the previous methoxyfenozide residue chemistry summary document has been 

issued in order to correct one of the commodity definitions recommended by HED in that 

document, and to revise Table 2.2.2 to reflect this corrected commodity definition. The earlier 

summary document (D425285; W .T. Drew; 31 March 2015) recommended removal of the 

existing 400-ppm tolerance in herb subgroup 19A, except chive, and the concomitant 

establishment of a 400-ppm tolerance in herb subgroup l 9A. Instead, a 400-ppm tolerance 

should be established in herb subgroup 19A, except chive, fresh leaves. 

Also, a row has been added to Table 2.2.2 to include the proposed removal of the tolerance in 

pistachio, as part of the conversion of tree nut group 14 to tree nut group 14-12. Although the 

removal of this tolerance was mentioned in the text of Sections 2.0 and 6.0, it was inadvertently 

omitted from Table 2.2.2; the corrected table is shown below. Revisions inserted in the table are 

shown in bold, highlighted font.

Chive* 4.5* Remove Covered by new chive tolerance in 

§ l 80.544[a][ 1]. 

* A tolerance is currently established at the listed level in the corresponding commodity. 

Additionally, the sentence "Subgroup l 9A only includes dried chives, not fresh" was deleted 

from the Table 2.2.2 Comments column in the third row under the 40CFR § 180.544[a](l] 

header.

Furthermore, wherever in the document the establishment of a tolerance in herb subgroup l 9A is 

mentioned, the reader should infer that the tolerance is actually being established in herb 

subgroup l 9A, except chive, fresh leaves.
