On 20 December 2006, Health Canada's Pest Management Regulatory Agency (PMRA) published for consultation Proposed Maximum Residue Limit document PMRL2006-01, Transitioning the Legal Establishment of Maximum Residue Limits (MRLs) for Pesticides from the Food and Drugs Act to the Pest Control Products Act: Consultation on Proposed MRLs. The document included MRLs proposed by the PMRA, prior to the Pest Control Products Act (PCPA) coming into force on 28 June 2006, and that had not been prepublished for comment in the Canada Gazette, Part I.

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

Appendix I summarizes the comments received in response to PMRL2006-01 and provides the PMRA's responses. Certain comments have led to the re-examination of supporting residue data,which has affected the MRLs to be established as a result of this action.

There have been several minor revisions to commodity descriptors to reflect current preferred terms and crop groupings but the scope of the MRLs identified herein are consistent with those proposed in PMRL2006-01, except where otherwise noted.

The MRLs identified herein are legally in effect as of the date of publication of this document.

A complete list of all MRLs established in Canada can be found on the PMRA's MRL webpage.

1.0 Comments Regarding MRLs for Lambda-cyhalothrin

Comments regarding MRLs proposed in Canada for residues of lambda-cyhalothrin in or on various fruit commodities were raised by four of the five respondents.

1.1 Stone Fruits

An American state agricultural trade association and the United States Department of Agriculture (USDA) were concerned that stone fruit¹ exports to Canada, its top export market (accounting for 10% of the state's production), may be negatively impacted given the differing residue limits for stone fruits in the two countries. While recognizing the need to maintain and promote consumer protection, the association believes that accepting American tolerances equally protects the Canadian consumer. The USDA requested information regarding the lambda-cyhalothrin use rates and patterns used to develop the proposed Canadian stone fruit MRLs.

The state agricultural trade association recognizes that the use pattern, including rates, differs between Canada and the United States but remains concerned regarding trade issues. The association has contacted the registrant regarding the need to set higher Canadian import MRLs consistent with established American tolerances.

The tolerance in the United States for lambda-cyhalothrin on stone fruits is 0.5 ppm while the trade association indicated that Canada was proposing an MRL for stone fruits of 0.07 ppm, which in fact only applied to nectarines and peaches (and not to cherries and plums). The following table compares proposed lambda-cyhalothrin Canadian MRLs and established American tolerances (as per  40 CFR 180.438) for stone fruit commodities.

Response

There are several reasons for differences in MRLs. Lambda-cyhalothrin is an insecticide that has been registered in Canada for use on stone fruits since the late 1980s. The proposed MRLs are based specifically on crop field trials conducted in regions representative of Canadian growing conditions (i.e. climate and soil types) and according to the Canadian use pattern. In Canada, the accepted use pattern is based on the lowest effective rate (i.e. use of the minimum amount of product at the lowest frequency that achieves adequate pest control). As noted by the USDA and summarized in the following table, the Canadian use pattern for stone fruits is considerably different from the American use pattern in regards to the rate per application, frequency of application and preharvest intervals (PHIs). The PMRA has a policy to keep the use rate and frequency of pesticide use at a level that is commensurate with sustainable pest management. Specific details regarding the Canadian use pattern for cherries, peaches, nectarines and plums are available on the Matador 120EC and Warrior Insecticide labels (PCPA Registration Numbers 24984 and 26837, respectively).

Use Patterns - United States and Canada

Country	Trade Name	Crop(s)/Crop Group	Application Rate (g a.i./ha)	Max. No. Applications per Season	Max. Seasonal Application Rate (g a.i./ha)	PHI (days)	Use Directions and Other Limitations
Canada	Warrior (PCPA Reg. No. 26837) Matador 120EC (PCPA Reg. No. 24984)	Cherries, peaches, nectarines, plums	12.5	3	37.5	7	Ground only. Allow a 7-day interval between applications.
United States	Warrior (USEPA Reg. No. 100-1112)	Stone fruits	22.4-44.8	Not specified	224	14	Apply with ground or air equipment.

The PMRA establishes crop group MRLs when a) the use pattern for all crops within a crop group are the same and b) if maximum residues for the representative crops are within a five-fold range. Further details regarding requirements for establishing crop group MRLs are found in Section 15.4 of the PMRA's Residue Chemistry Guidelines (DIR98-02).

Upon re-examination of the Canadian crop field trial data submitted to support the registration of Matador and Warrior for use on stone fruits, it was noted that the maximum residues of lambda-cyhalothrin on cherries and plums in trials conducted in Ontario during the 1988 growing season were 0.177 ppm and 0.110 ppm, respectively, when treated at 30 to 45 g a.i./ha/season and harvested seven days following the last of three applications (equivalent to 1.2-fold the approved use pattern).

Therefore, an MRL for these stone fruits should be proposed at 0.2 ppm, rather than at 0.08 ppm for cherries and 0.01 ppm for plums as proposed in PMRL2006-01. In addition, as this MRL is less than five times the supported 0.07 ppm MRL proposed for nectarines and peaches, an MRL of 0.2 ppm for the stone fruit crop group will be proposed and consulted on in a future Proposed Maximum Residue Limit document.

It should be noted that an application has recently been received to set MRLs for imported stone fruits. Upon completion of the review of food residue chemistry data, the PMRA will be in a better position to determine if the American tolerances for lambda-cyhalothrin can be adopted. The target completion date of this submission is early 2009.

The lambda-cyhalothrin MRLs proposed for stone fruits in PMRL2006-01 will not be established at this time.

1.2 Pome Fruits

An American state agricultural marketing board and the USDA raised concerns regarding MRLs proposed for lambda-cyhalothrin on pears and further questioned why the proposed MRLs in Canada for apples and pears differed significantly given that they are both commodities in the pome fruits² crop group. The Canadian market accounts for 10% of the state's fresh pear shipments and 50% of its total exports. The American state agricultural marketing board requested that the PMRA adopt a pear import MRL for lambda-cyhalothrin consistent with the United States Environmental Protection Agency's (USEPA's) tolerance of 0.3 ppm or at least re-establish the 0.1 ppm default MRL. Otherwise, the preharvest interval necessary for Canadian MRL compliance for imported pears may preclude the use of the pesticide altogether. The USDA has requested an explanation of the methods used in establishing the MRL on pears and the basis for proposing distinct MRLs for apples and pears rather than specifying a pome fruits crop group MRL. The failure to establish a crop group MRL was also questioned by a Canadian registrant.

The following table compares proposed lambda-cyhalothrin Canadian MRLs and established American tolerances for pome fruit commodities (as per  40 CFR 180.438).

Common Name: Lambda-cyhalothrin

Canada

Food Commodity / Proposed MRL parts per million (ppm)

Apples / 0.07

Pears / 0.01

United States

Food Commodity / Tolerance parts per million (ppm)

Fruits, pome, group 11 / 0.3

Response

The ability to establish MRLs on a crop group basis requires a consistent use pattern for all food commodities within the group. For the labelled Canadian uses of lambda-cyhalothrin, there is a significant difference between both the maximum product application rate and the number of applications per year for apples and pears, thereby negating the ability to establish an MRL for the pome fruits crop group. The Canadian use patterns for apples and pears are compared to the American use pattern for pome fruits in the following table. However, specific details regarding the Canadian use pattern for apples and pears are available on the Matador 120EC and Warrior Insecticide labels (PCPA Registration Numbers 24984 and 26837, respectively).

Further details regarding requirements for establishing crop group MRLs are found in Section 15.4 of the PMRA's Residue Chemistry Guidelines (DIR98-02).

Comparison of Directions for Use in Canada and the United States

Country	Trade Name	Food Commodity	Application Rate (g a.i./ha)	Max. No. Applications per Season	Max. Seasonal Application Rate (g a.i./ha)	PHI (days)	Use Directions
Canada	Warrior (PCPA Reg. No. 26837) Matador 120EC (PCPA Reg. No. 24984)	Apples	10.0-12.5	3	37.5	7	Ground only. Allow a 7-day interval between applications
		Pears	10.0	1	10.0	7	Ground only
United States	Warrior (USEPA Reg. No. 100-1112)	Pome fruits	22.4-44.8	Not specified	224	21	Apply with ground or air equipment.

Given the distinct use pattern and the more than five-fold variability in the resulting residues, individual MRLs of 0.07 ppm and 0.01 ppm, respectively, were proposed and remain valid as supported by corresponding residue trial data.

Therefore, the lambda-cyhalothrin MRLs proposed for apples and pears in PMRL2006-01 are not impacted and are established at 0.07 ppm and 0.01 ppm, respectively.

2.0 Comments Regarding MRLs for Sulfuryl Fluoride

The USDA challenged differing proposed MRLs for sulfuryl fluoride on tree nuts³ given it believes the same data were submitted to Canada, the United States and Codex to establish MRLs on the crop group. Trade concerns are the issue at hand as Canada is the fourth largest export market for California almonds after the European Union, Japan and India, and some 60% of California almond production is exported. The USDA has requested information describing the methods Canada used in setting the nut MRLs, which differ from the American and Codex values. In particular, it has requested information supporting the difference between the proposed MRLs for almonds (0.01 ppm) and walnuts (2.0 ppm). The USDA is under the understanding that residues measured in these nuts are similar.

The following table compares proposed Canadian MRLs, established American tolerances (as per  40 CFR 180.575) and  Codex MRLs for tree nuts.

Common Name: Sulfuryl fluoride

Canada

Food Commodity / Proposed MRL parts per million (ppm)

Pecans / 3.0

Walnuts / 2.0

Pistachios / 0.3

Almonds / 0.01

United States

Food Commodity / Tolerance parts per million (ppm)

Nut, tree, group 14, postharvest / 3.0

Codex

Food Commodity / MRL parts per million (ppm)

Tree nuts / 3.0

Response

The main reason for the difference in MRLs/tolerances is the adoption of crop groupings, which has been more widely applied in the United States than in Canada. This results in the highest MRL in a crop being adopted for the entire group. However, as indicated for lambda-cyhalothrin and as found in Section 15.4 of the PMRA's Residue Chemistry Guidelines (DIR98-02), if the maximum residue level for a crop within a crop group is five-fold different from the other representative crops within the same crop group, separate MRLs must be established, as was the case for the proposed MRLs for sulfuryl fluoride on tree nuts.

After re-examination of the supporting fumigation trial data, maximum residues of sulfuryl fluoride in or on almonds was 0.04 ppm following a single maximum dosage of 1517-1539 mgChr/L under normal atmospheric pressure (equivalent to the value on the American label) and an aeration period of one day. In addition, maximum residues of sulfuryl fluoride in or on walnuts was 0.64 ppm when treated with a single maximum dosage of 183-218 mg.hr/L under vacuum (equivalent to the American label) and an aeration period of one day.

Therefore, the 0.01 ppm and 2.0 ppm MRLs proposed for almonds and walnuts, respectively, in PMRL2006-01 should be revised. MRLs of 0.04 ppm and 0.7 ppm will be proposed for consultation in a future Proposed Maximum Residue Limit document.

Although the MRLs/tolerances may be numerically different, there is no expectation that, if used according to the registered American label (1500 mg.hr/L under normal atmospheric pressure and 200 mg.hr/L under vacuum, one-day aeration period), the residues of sulfuryl fluoride will exceed the maximum levels reported in the trials, upon which the Canadian MRLs are established. Therefore, the differences in MRLs/tolerances should not result in real trade barriers.

The sulfuryl fluoride MRLs proposed for pecans and pistachios in PMRL2006-01 are not impacted and are established at 3.0 ppm and 0.3 ppm, respectively.

The sulfuryl fluoride MRLs proposed for almonds and walnuts in PMRL2006-01 will not be established at this time.

3.0 Comments Regarding MRLs for Fluazifop-butyl and Fluazifop-p-butyl

A Canadian registrant noted that the proposed MRL for the isomer fluazifop-p-butyl on grapes is listed under fluazifop-p-butyl rather than under the racemic fluazifop-butyl, as are all currently established MRLs. The registrant noted that there may be confusion because of the establishment of tolerances for both active ingredients.

It was also correctly noted that there are no longer any products registered in Canada containing the racemic fluazifop-butyl but only products containing the active isomer fluazifop-p-butyl. The registrant further claimed that the USEPA had migrated all existing tolerances for fluazifop-butyl to fluazifop-p-butyl and requested that Canada adopt a similar approach.

Response

The entry under fluazifop-p-butyl is in error, and the grape MRL should have been listed under Section 1 of PMRL2006-01 as an MRL for fluazifop-butyl. Given that the enforcement analytical method determines fluazifop acid and does not distinguish between isomers, all future MRLs will also be identified under fluazifop-butyl.

American tolerances are currently established for both fluazifop-butyl and fluazifop-p-butyl in accordance with 40 CFR 180.411.

4.0 Comments Regarding MRLs for Diquat

A Canadian registrant made comments regarding diquat MRLs, claiming that the MRLs proposed in PMRL2006-01 differed from those established in the United States, as a result of an April 2002 Tolerance Reassessment Decision (TRED), and requested that any MRLs established for diquat be harmonized with American tolerances.

Response

It should be noted that many of the proposed Canadian MRLs for diquat are consistent with tolerances established in the United States. The following represent the exceptions.

Food Commodity / Canadian MRL (ppm) / American Tolerance (ppm)

Brassica Leafy Vegetables / 0.02 / 0.05

Crop Group 5 Dry beans and peas / 0.2 / 0.05

Soybean seeds / 0.05 / 0.2

The MRLs proposed in PMRL2006-01 that differ from American tolerances remain valid as supported by corresponding residue trial data and are not impacted as a result of these comments. All diquat MRLs included in PMRL2006-01 are established as proposed.

5.0 General Comments Regarding MRL Differences With the United States

A Canadian registrant provided a comprehensive comparison of the proposed Canadian MRLs for its products listed in PMRL2006-01 to established American tolerances, while recognizing that some significant differences are due to different use patterns in the two countries. However, without providing specific examples, the registrant questioned why proposed MRLs for crops not grown in Canada differed from corresponding American tolerances, even though the same data were used to establish both. The registrant further claimed that differing values resulted when the same residue data were available to both Canada and the United States, with specific reference to discrepancies for cyprodinil, fludioxonil, lambda-cyhalothrin and metalaxyl.

While recognizing that the PMRA has often not been provided with the available crop residue data upon which the American tolerances have been established, the registrant recommended that the PMRA and the USEPA work together to harmonize the processes to establish MRLs and tolerances.

The registrant requested that consideration be given to the MRL discrepancies outlined in the submitted table before they are established and stated that, as a minimum, the default/general MRL of 0.1 ppm should be maintained so that trade is not disrupted.

A trade association also made a general claim that 42 American tolerances for stone fruits are above the 0.1 ppm Canadian default MRL, therefore requiring considerable resources to prepare data packages and convince registrants to support import tolerances. The association also believes that accepting American tolerances above 0.1 ppm should be equally protective of Canadian consumers given the similarity in diet between the two countries.

Response

Differing use patterns (rate, number of applications, timing of applications, PHIs) between countries may result from differing pests/pest pressures or existing integrated pest management strategies such that one would expect differing residue levels remaining in or on food at harvest. In addition, regional climatic differences can result in varying food residues leading to the requirement for differing MRLs/tolerances.
