Under the authority of the  Pest Control Products Act, Health Canada's Pest Management Regulatory Agency (PMRA) has concluded that the addition of new uses on tuberous and corm vegetables (Crop Subgroup 1C), pome fruits (Crop Group 11-09), stone fruits (Crop Group 12-09), tree nuts (Crop Group 14), field corn, mint and popcorn to the product labels of Dupont Altacor or Dupont Coragen Insecticides, containing technical grade chlorantraniliprole, is acceptable. The specific uses approved in Canada are detailed on the labels of Dupont Altacor and Dupont Coragen Insecticides, Pest Control Products Act Registration Numbers 28981 and 28982, respectively.

The evaluation of these chlorantraniliprole applications indicated that the end-use products have merit and value and the human health and environmental risks associated with the new uses are acceptable. Details regarding the registration can be found in the corresponding Evaluation Reports that are available in the Pesticides and Pest Management section of Health Canada's website, under Public Registry, Pesticide Product Information Database.^{Footnote 1}

Before registering a pesticide for food use in Canada, the PMRA must determine the quantity of residues that are likely to remain in or on the food when the pesticide is used according to label directions and that such residues will not be a concern to human health. This quantity is then legally established as a maximum residue limit (MRL). An MRL applies to the identified raw agricultural food commodity as well as to any processed food product that contains it, except where separate MRLs are specified for the raw agricultural commodity and a processed product made from it.

In addition, the PMRA is proposing to establish MRLs for chlorantraniliprole on coffee and rice to permit the sale and import of foods containing these residues. The PMRA has determined the quantity of residues that are likely to remain in or on the imported food commodities when chlorantraniliprole is used according to label directions in the exporting country. The Agency has also determined that such residues will not be a concern to human health and is proposing to legally establish corresponding import MRLs. Details regarding the proposed import MRLs can also be found in the Evaluation Reports.

The MRLs proposed for pome fruits, stone fruits and certain livestock commodities in this action are to revise existing MRLs to accommodate changes in the labelled use pattern. Potatoes are excluded from the proposed MRL for tuberous and corm vegetables as the same 0.01 ppm MRL is already established for the commodity.

Consultation on the proposed MRLs for chlorantraniliprole is being conducted via this document (see Next Steps, the last section of this document).

To comply with Canada's international trade obligations, consultation on the proposed MRLs is also being conducted internationally by notifying the  World Trade Organization, as coordinated by the  Standards Council of Canada.

The proposed MRLs in Canada in or on food, to replace or be added to the MRLs already established for chlorantraniliprole, are as follows.

Common Name	Residue Definition	MRL (ppm)	Food Commodity
Table 1 footnotes ppm = parts per million Table 1 footnote 1 The MRL is proposed to replace the existing 1.0 ppm MRL for stone fruits and establish a new MRL for the additional commodities in the expanded 2009 crop group. Return to table 1 footnote A referrer Table 1 footnote 2 The MRL is proposed to replace the existing 0.3 ppm MRL for pome fruits and establish a new MRL for the additional commodities in the expanded 2009 crop group. Return to table 1 footnote C referrer Table 1 footnote 3 The MRL is proposed to replace the existing 0.01 ppm MRL for fat and meat byproducts of the listed livestock.

Chlorantraniliprole	3-bromo-N-[4-chloro-2-methyl-6-[(methylamino) carbonyl]phenyl]-1-(3-chloro-2-pyridinyl)-1H-pyrazole-5-carboxamide	9.0	Peppermint tops, spearmint tops
		2.5	Stone fruits (Crop Group 12-09)Footnote A
		1.0	Coffee (instant)
		0.4	Pome fruits (Crop Group 11-09)Footnote B
		0.15	Coffee (green beans), rice
		0.05	Fat and meat byproducts of cattle, goats, horses, and sheepFootnote C
		0.02	Tree nuts (Crop Group 14), field corn, pistachios, popcorn grain
		0.01	Tuberous and corm vegetables (Crop Subgroup 1C, except potatoes); eggs; fat, meat and meat byproducts of hogs and poultry

MRLs are proposed for each commodity included in the listed crop groupings in accordance with the Residue Chemistry Crop Groups webpage in the Pesticides and Pest Management section of Health Canada's website.

A complete list of all pesticide MRLs established in Canada can be found on the Maximum Residue Limits for Pesticides webpage in the Pesticides and Pest Management section of Health Canada's website.

International Situation and Trade Implications

MRLs may vary from one country to another for a number of reasons, including differences in pesticide use patterns and the locations of the field crop trials used to generate residue chemistry data. For livestock commodities, differences in MRLs can also be due to different livestock feed items and practices.

Table 2 compares the MRLs proposed for chlorantraniliprole in Canada with the corresponding American tolerances and Codex MRLs. American tolerances are listed in the  Electronic Code of Federal Regulations, 40 CFR Part 180, by pesticide. Note that there will be commodities in Canada without corresponding American tolerances as Canadian MRLs are proposed for the expanded 2009 pome and stone fruit crop groupings, in accordance with the Residue Chemistry Crop Groups webpage in the Pesticides and Pest Management section of Health Canada's website. Codex MRLs for chlorantraniliprole are listed on the Codex Alimentarius^{Footnote 2}  Pesticide Residues in Food webpage, by pesticide or commodity.

Please forward your comments to Publications. The PMRA will consider all comments received before making a final decision on the proposed MRLs for chlorantraniliprole and posting a corresponding Established Maximum Residue Limit document in the Pesticides and Pest Management section of Health Canada's website.
