Modification of the existing maximum residue levels for sulfoxaflor in various crops
Abstract
In accordance with Article 6 of Regulation (EC) No 396/2005, the applicant Dow AgroSciences submitted a request to the competent national authority in Ireland to modify the existing maximum residue levels (MRLs) for the active substance sulfoxaflor in various crops, including limes imported from Australia. The data submitted in support of the request were found to be sufficient to derive MRL proposals for limes, cauliflowers, Brussels sprouts, kales, spinaches and similar leaves, herbs and edible flowers, beans without pods, peas with pods, oat, rye and triticale (wheat). Adequate analytical methods for enforcement are available to control the residues of sulfoxaflor on the commodities under consideration. Based on the risk assessment results, EFSA concluded that the use of sulfoxaflor according to the intended good agricultural practices is unlikely to present a risk to consumers’ health.
Summary
In accordance with Article 6 of Regulation (EC) No 396/2005, Dow AgroSciences submitted an application to the competent national authority in Ireland (evaluating Member State, EMS) to modify the existing maximum residue levels (MRLs) for the active substance sulfoxaflor in cauliflowers, Brussels sprouts, kales, beans (without pods), peas (with pods), spinaches and similar leaves (except spinaches), herbs and edible flowers (except celery leaves), rye, oats and wheat (triticale) and in limes imported from Australia. The EMS drafted an evaluation report in accordance with Article 8 of Regulation (EC) No 396/2005, which was submitted to the European Commission and forwarded to the European Food Safety Authority (EFSA) on 7 April 2017. The EMS proposed to establish an MRL for limes imported from Australia as 0.5 mg/kg and proposed to modify the existing MRLs as follows:
for cauliflowers from 0.04 mg/kg to 0.1 mg/kg, for Brussels sprouts from the limit of quantification (LOQ) of 0.01 mg/kg to 0.015 mg/kg, for kales from the LOQ of 0.01 mg/kg to 1 mg/kg; for the whole group spinaches and similar leaves (except spinaches) from the LOQ 0.01 mg/kg to 0.2 mg/kg, for the whole group of herbs and edible flowers (except celery leaves) from the LOQ of 0.02 mg/kg to 0.2 mg/kg; for beans (without pods) from the LOQ 0.01 mg/kg to 0.03 mg/kg, for peas (with pods) form the LOQ of 0.01 mg/kg to 0.15 mg/kg. Finally, the EMS proposed to raise the existing MRL for oat from 0.04 mg/kg to 0.06 mg/kg, for rye from 0.015 mg/kg to 0.03 mg/kg and for triticale from the LOQ 0.01 mg/kg to 0.03 mg/kg. EFSA assessed the application and the evaluation report as required by Article 10 of the MRL regulation. EFSA identified data gaps or points which needed further clarification, which were requested from the EMS. On 14 September 2018, the EMS submitted a revised evaluation report, which replaced the previously submitted evaluation report.
Based on the conclusions derived by EFSA in the framework of Regulation (EC) No 1107/2009, the data evaluated under previous MRL assessments and the additional data provided by the EMS in the framework of this application, the following conclusions are derived.
The metabolism of sulfoxaflor was investigated in primary crops belonging to the groups of fruit crops, root crops, leafy crops, cereals and pulses/oilseeds following foliar or soil application and in rotational crops (root/tuber crops, leafy crops and cereals) following application of sulfoxaflor to bare soil. Studies investigating the effect of processing of both sulfoxaflor and the plant metabolite X11719474 (hydrolysis studies) demonstrated that the substances are stable under standard hydrolysis conditions.
Based on the metabolic pattern identified in metabolism studies, hydrolysis studies, the toxicological significance of metabolite X11719474, the peer review derived the residue definitions for plant products as ‘sulfoxaflor (sum of isomers)’ for enforcement and ‘sum of sulfoxaflor and the metabolite X11719474, expressed as sulfoxaflor’ for risk assessment. These residue definitions are appropriate for primary crops including the crops under assessment and the processed products.
Sufficiently validated analytical methods are available to quantify residues according to the enforcement residue definition for the crops under consideration. The methods enable quantification of residues at or above 0.01 mg/kg (LOQ).
The available residue trials are sufficient to derive MRL proposals for all the crops assessed in this opinion.
Studies investigating the effect of processing on the magnitude of residues in cereals and citrus are available. Due to the limited data set, the processing factors (PF) derived for cereals and citrus are not recommended to be included in Annex VI of Regulation (EC) No 396/2005. For the remaining commodities, specific processing studies were not provided and are not required.
The occurrence of residues in rotational crops was investigated in the framework of the European Union (EU) pesticides peer review. Based on the available information, EFSA could not exclude that the use of sulfoxaflor according to the intended good agricultural practice (GAP) will result in significant residues of its metabolite X11719474 in rotational corps, particularly in feed items. When the new uses are authorised at national level, Member States should consider the need of setting specific risk mitigation measures to avoid the presence of the metabolite in rotational crops.
As several crops under consideration and their by‐products are used as feed item, a potential carry‐over into food of animal origin was assessed. The calculated livestock dietary burden exceeded the trigger value of 0.1 mg/kg dry matter (DM) for all relevant animal species. However, considering that the Codex maximum residue levels (CXL) implemented in the MRL legislation were based on higher estimates compared to the dietary burdens obtained with the EU uses, EFSA concluded that a revision of the existing MRLs for commodities of animal origin is not necessary.
The toxicological profile of sulfoxaflor was assessed in the framework of the EU pesticides peer review under Regulation (EC) No 1107/2009 and the data were sufficient to derive an acceptable daily intake (ADI) of 0.04 mg/kg body weight (bw) per day and an acute reference dose (ARfD) of 0.25 mg/kg bw. The toxicological reference values of parent compound also apply to the metabolite X11719474 included in the residue definition for risk assessment.
The consumer risk assessment was performed with revision 2 of the EFSA Pesticide Residues Intake Model (PRIMo). EFSA concluded that the use of sulfoxaflor according to the intended good agricultural practices will not result in a consumer exposure exceeding the toxicological reference values and therefore is unlikely to present a risk to consumers’ health.
EFSA proposes to amend the existing MRLs as reported in the summary table below. Full details of all end points and the consumer risk assessment can be found in Appendices B–D.

Assessment
The European Food Safety Authority (EFSA) received the request to assess the application on the modification of the existing maximum residue levels (MRLs) for sulfoxaflor in various crops, including limes imported from Australia. The detailed description of the intended European Union (EU) uses and the use on limes in Australia, which are the basis for the current MRL application on sulfoxaflor, is reported in Appendix A. In Australia, sulfoxaflor is authorised for the use on citrus fruits and a MRL of 0.7 mg/kg is established based on the residue definition for enforcement as ‘parent sulfoxaflor’.
Sulfoxaflor is the ISO common name for methyl(oxo){1‐[6‐(trifluoromethyl)‐3‐pyridyl]ethyl}‐λ6‐sulfanylidene]cyanamide (IUPAC). It is a mixture of two diastereomeric pairs of enantiomers in the range of 40:60 to 60:40% (w/w). The chemical structures of the active substance and its main metabolite are reported in Appendix E.
Sulfoxaflor was evaluated in the framework of Regulation (EC) No 1107/20091 with Ireland designated as rapporteur Member State (RMS). The representative uses assessed were foliar spraying treatments on fruiting vegetables, spring and winter cereals and cotton to control sap feeding insects. The draft assessment report (DAR) prepared by the RMS has been peer reviewed by EFSA (2014). Sulfoxaflor was approved2 for the use as an insecticide on 18 August 2015. When granting national authorisations, Member States have to consider risk mitigation measures related to the risk for bees, bumble bees and other non‐target arthropods.
The European Union (EU) MRLs for sulfoxaflor have been assessed in the framework of the peer review established in Annex II of Regulation (EC) No 396/20053. After the finalisation of the peer review, EFSA has issued one reasoned opinion on the modification of MRLs for sulfoxaflor on grape leaves and globe artichokes; the proposed MRLs have been considered in the EU MRL legislation.4 In 2017, certain Codex maximum residue limits (CXLs) have been implemented in Regulation (EU) 2017/4055.
In accordance with Article 6 of Regulation (EC) No 396/2005, Dow AgroSciences submitted an application to the competent national authority in Ireland (EMS) to modify the existing MRLs for the active substance sulfoxaflor in various crops. The EMS drafted an evaluation report in accordance with Article 8 of Regulation (EC) No 396/2005, which was submitted to the European Commission and forwarded to EFSA on 7 April 2017. The EMS proposed to raise the existing MRL for sulfoxaflor for cauliflowers from 0.04 mg/kg to 0.1 mg/kg, for Brussels sprouts from the limit of quantification (LOQ) of 0.01 mg/kg to 0.015 mg/kg, for kales from the LOQ of 0.01 mg/kg to 1 mg/kg; for the whole group spinaches and similar leaves (except spinaches) from the LOQ 0.01 mg/kg to 0.2 mg/kg, for the whole group of herbs and edible flowers (except celery leaves) from the LOQ of 0.02 mg/kg to 0.2 mg/kg; for beans (without pods) from the LOQ 0.01 mg/kg to 0.03 mg/kg, for peas (with pods) form the LOQ of 0.01 mg/kg to 0.15 mg/kg. Finally, the EMS proposed to raise the existing MRL for oat from 0.04 mg/kg to 0.06 mg/kg, for rye from 0.015 mg/kg to 0.03 mg/kg and for triticale from the LOQ 0.01 mg/kg to 0.03 mg/kg. EFSA identified data gaps or points which needed further clarification, which were requested from the EMS. On 14 September 2018, the EMS submitted a revised evaluation report, which replaced the previously submitted evaluation report.
EFSA based its assessment on the revised evaluation report submitted by the EMS (Ireland, 2018), the DAR and its addendum (Ireland, 2012, 2014) prepared under Regulation (EC) 1107/2009, the Commission review report on sulfoxaflor (European Commission, 2015), the conclusion on the peer review of the pesticide risk assessment of the active substance sulfoxaflor (EFSA, 2014) as well as the conclusions from a previous EFSA opinion on sulfoxaflor (EFSA, 2017).
For this application, the data requirements established in Regulation (EU) No 544/20116 and the guidance documents applicable at the date of submission of the application to the EMS are applicable (European Commission, 1997a,b,c,d,e,f,g, 2000, 2010a,b, 2017; OECD, 2011, 2013). The assessment is performed in accordance with the legal provisions of the Uniform Principles for the Evaluation and the Authorisation of Plant Protection Products adopted by Commission Regulation (EU) No 546/20117.
A selected list of end points of the studies assessed by EFSA in the framework of this MRL application, including the end points of relevant studies assessed previously, are presented in Appendix B.
The revised evaluation report submitted by the EMS (Ireland, 2018) and the exposure calculations using the EFSA Pesticide Residues Intake Model (PRIMo) are considered as supporting documents to this reasoned opinion and, thus, are made publicly available as background documents to this reasoned opinion.
1. Residues in plants
1.1. Nature of residues and methods of analysis in plants
1.1.1. Nature of residues in primary crops
The metabolism of sulfoxaflor in primary corps belonging to the group of fruit cops, leafy crops, cereals/grass and pulses/oilseeds has been investigated in the framework of the EU pesticides peer review (EFSA, 2014). After foliar applications, parent sulfoxaflor was the most significant residue (16–71% of total radioactive residue (TRR)) with the metabolite X11719474 as a major metabolite in mature crops. After soil applications, sulfoxaflor was present in a much lower proportion (fruit crops) or not even detected (pulses and cereals) and the metabolite X11719474 was the major residue. In the metabolism studies, no significant shift was reported for the diastereomer ratios. Information on the ratio of the enantiomers present in the individual diastereomers of sulfoxaflor and X11719474 was not available. Nonetheless, the EU pesticides peer review did not identify the need for additional data.
1.1.2. Nature of residues in rotational crops
Sulfoxaflor is proposed for use in crops that can be grown in crop rotation. The metabolism of sulfoxaflor in rotational crops was investigated in root/tuber crops, leafy crops and cereals after bare soil application in the framework of the EU pesticides peer review (EFSA, 2014). Sulfoxaflor rapidly degraded with X11719474 being the most abundant metabolite found in confined rotational crop studies.
1.1.3. Nature of residues in processed commodities
The effect of processing on the nature of sulfoxaflor and its metabolite X11719474 was investigated in the framework of the EU pesticides peer review (EFSA, 2014). Both sulfoxaflor and X11719474 were considered to be sufficiently stable under standard hydrolysis conditions.
1.1.4. Methods of analysis in plants
Sufficiently validated analytical methods are available to enforce residues of sulfoxaflor in high water content, high acid content, high oil content and dry commodities. The methods allow quantifying residues at or above the LOQ of 0.01 mg/kg (EFSA, 2014).
1.1.5. Stability of residues in plants
The stability of sulfoxaflor and the metabolite X11719474 in plants under conditions of frozen storage was investigated in the framework of the EU pesticides peer review (EFSA, 2014). It was demonstrated that in the crops assessed in this application, residues of both compounds were stable for at least 22 months.
1.1.6. Proposed residue definitions
Based on the metabolic pattern identified in metabolism studies, the results of hydrolysis studies, the toxicological significance of the metabolite X11719474, the following residue definitions were proposed in the EU pesticides peer review (EFSA, 2014):
- residue definition for enforcement: Sulfoxaflor (sum of isomers).
The residue definition for enforcement set in Regulation (EC) No 396/2005 is identical with the above mentioned residue definition.
- residue definition for risk assessment: Sum of sulfoxaflor and metabolite X11719474, expressed as sulfoxaflor.
These residue definitions are appropriate for primary crops, including the crops under assessment, and processed products.
1.2. Magnitude of residues in plants
1.2.1. Magnitude of residues in primary crops
- Limes, imported from Australia
The applicant provided the results of six residue trials on lemons carried out in the USA and compliant with the Australian good agricultural practice (GAP). Although these data were generated outside the exporting country, the conditions of cultivation (such as cultural practices and climatic conditions) across lemon producing countries are comparable, and the results were accepted to support the import tolerance request for limes, which are classified as minor crops. The number of trials is sufficient to derive a MRL proposal of 0.5 mg/kg for limes, by extrapolation from lemons (European Commission, 2017).
The MRL set in the exporting country is 0.7 mg/kg. This MRL has been derived from a combined data set of residue trials in various citrus (oranges, mandarins, lemons and grapefruits); thus, the difference between the MRL in the country of origin and the MRL proposal derived by EFSA is explained by a different policy on setting MRLs.
- Cauliflowers, northern and southern EU use
In support of the northern Europe (NEU) GAP, the applicant provided the results of 12 residue trials: 6 trials were performed in cauliflowers and 6 trials in broccoli. Also for the southern Europe (SEU) GAP, 12 residue trials were provided (6 trials in cauliflowers and 6 trials in broccoli). All trials were compliant with the intended GAP. For each geographical zone, the number of trials is sufficient to derive a MRL from the combined data set of residues in cauliflowers and broccoli (European Commission, 2017). The NEU trials resulted in a slightly higher MRL proposal.
- Brussels sprouts, northern and southern EU use
The results of six residue trials conducted in the NEU and four residue trials conducted in the SEU compliant with the intended GAP were submitted. The number of trials is sufficient to derive a MRL for each geographical zone. Since the trials representing the NEU and SEU use belong to the same population, the NEU and SEU data sets were pooled to calculate a more robust MRL proposal.
- Kales, northern and southern EU use
Four residue trials conducted in the NEU and four residue trials conducted in the SEU compliant with the intended GAP were submitted. The number of trials is sufficient to derive a MRL for each geographical area. The NEU trials resulted in a slightly higher MRL proposal.
- Spinaches and similar leaves (except spinaches) and herbs and edible flowers (except celery leaves), northern and southern EU use
In support of the application, six residue trials conducted in the NEU and seven residue trials conducted in the SEU performed in open leaf lettuces and compliant with the intended GAPs were submitted. For each geographical zone, the number of trials is sufficient to derive a MRL proposal which can be extrapolated to spinaches and similar leaves and herbs and edible flowers (European Commission, 2017). The SEU trials resulted in a slightly higher MRL proposal.
- Beans without pods, northern and southern EU use
The results of four residue trials conducted in the NEU and four residue trials conducted in the SEU compliant with the intended GAP were submitted. The number of trials is sufficient to derive a MRL for each geographical zone. The SEU trials resulted in a slightly higher MRL proposal.
- Peas with pods, southern EU use
The results of four residue trials conducted in the SEU on beans with pods compliant with the intended GAP on peas were submitted. The number of trials is sufficient to derive a MRL proposal for peas with pods by extrapolation from residues in beans with pods (European Commission, 2017).
- Oat, northern and southern EU use
In support of the intended GAP in oats, nine NEU residue trials and ten SEU residue trials performed on barley were submitted. The trials were compliant with the intended GAP in oat.
In each test site, side‐by‐side trials were conducted with different treatment regimens (1 × 24 g/ha and 2 × 24 g/ha). EFSA agreed with the approach of the EMS to select the highest residue value observed in the comparative side‐by‐side trials. Additionally, in some of the trials a suspension concentrate (SC) formulation was used instead of a water‐dispersible granule (WG) formulation. The deviation is of no relevance as according to the guidance document and the two formulations are expected to produce comparable residues when last application occurs more than seven days prior to harvest (European Commission, 2017). For each geographical zone, the number of trials is sufficient to derive a MRL proposal which can be extrapolated to oats (European Commission, 2017). The SEU trials resulted in a higher MRL proposal.
- Rye, northern and southern EU use
In support of the intended GAP in rye, eight NEU residue trials and eight SEU residue trials conducted on wheat were submitted. The trials were compliant with the intended GAP on rye. Also, these trials were designed as comparative trials, testing one and two applications in side‐by‐side plots; some trials were performed with the SC formulation, which is acceptable for the same reasons as reported under point h. For each geographical zone, the number of trials is sufficient to derive a MRL proposal which can be extrapolated to rye (European Commission, 2017). The NEU trials resulted in a higher MRL proposal.
- Wheat (triticale), northern and southern EU use
The applicant reported a GAP for triticale for which a MRL modification was requested. According to Regulation (EU) 2018/628, triticale is classified under the same code as wheat and therefore the same MRL as for wheat applies. The NEU and SEU residue trials on wheat (see point i) therefore support the intended use on triticale.
In addition, the applicant provided information on the magnitude of residues in barley and wheat straw, which was extrapolated to oat and rye straw. The residue data were included in the dietary burden calculation (see Section 2).
According to the assessment of the EMS, the samples of the residue trials were analysed with methods appropriately validated and stored under conditions for which their integrity was demonstrated (Ireland, 2018). All samples were analysed for the parent compound and the metabolite X11719474, which is included in the residue definition for risk assessment.
1.2.2. Magnitude of residues in rotational crops
Based on the results of the confined rotational crop metabolism studies, which were conducted at a total application rate significantly higher (12.5N) than the intended rates on the crops under assessment (maximum seasonal application rate of 48 g/ha), residues of sulfoxaflor are not expected. Metabolite X11719474 was found, mostly in the leafy parts of the crops in rotation (lettuces, radish tops, wheat forage and straw). This finding was confirmed by field studies with rotational crops conducted in the EU (radishes, lettuces, spring onions and barley) and outside the EU (radishes, mustard greens, sorghum and grass). These studies were assessed during the EU pesticides peer review (EFSA, 2014).
EFSA could not exclude that the use of sulfoxaflor according to the intended GAP will result in significant residues in rotational corps, particularly in feed items. When the new uses are authorised at national level, Member States should consider the need of setting specific risk mitigation measures to avoid the presence of the metabolite of sulfoxaflor X11719474 in rotational crops.
1.2.3. Magnitude of residues in processed commodities
Processing studies investigating the magnitude of sulfoxaflor residues in processed cereals were assessed in the framework of the EU pesticides peer review (EFSA, 2014.) Since samples were analysed for parent compound only, the processing factors derived have a limited value for the dietary risk assessment.
In this MRL application, the distribution of residues into peel and pulp and the results of processing studies in oranges and grapefruits were evaluated. Samples were analysed for sulfoxaflor and X11719474. Residues were located in the fruit peel and tended to dilute in orange juice, oil and canned orange slices. Due to the limited data set, only tentative processing factors could be derived.
For the other crops assessed in this application, significant residues (> 0.1 mg/kg) are not expected in raw commodities or, if exceeding this trigger value (i.e. kales), the individual contribution of these crops to the human diet is expected to be low. Therefore, further processing studies are not required.
1.2.4. Proposed MRLs
The available data were considered sufficient to derive MRL proposals as well as risk assessment values for all the commodities under evaluation. For triticale, the intended use does not require a change of the existing MRL in wheat (the main crop to which triticale belongs for MRL setting), which is at a higher level in the EU legislation. In Section 3, EFSA assessed whether residues on these crops resulting from the intended uses are likely to pose a consumer health risk.
Conversion factors (CF) from enforcement to risk assessment at the intended PHI have been derived from the trials with residues above the LOQ in the raw commodity (see Appendix B.1.2.1).
2. Residues in livestock
2.1. Nature of residues and methods of analysis in livestock
Several products and their by‐products under consideration can be used as feed items. Therefore, EFSA calculated the livestock dietary burden in accordance with the OECD guidance document (OECD, 2013), based on the residues expected in feed derived from the crops for which the use of sulfoxaflor is authorised in the EU (assessed in the framework of the EU pesticides peer review) and the intended uses requested in this MRL application. The input values used for the dietary burden calculation are summarised in Appendix D.1.
The maximum dietary burden for cattle, sheep and swine (all diets) was 1.87, 2.04 and 0.97 mg/kg dry matter (DM), respectively. For poultry, the maximum dietary burden was 0.34 mg/kg DM (see Appendix B.2).
The current EU MRLs for muscle, fat, liver, kidney, edible offal, milks and eggs of livestock were derived from the existing Codex MRLs (CXL), which were derived taking into account the maximum dietary burden calculated at international level (i.e. 3.22 mg/kg DM for beef and dairy cattle and 0.93 mg/kg for poultry) (FAO, 2014). Considering that the dietary burden calculated for the EU is below the dietary burden calculated at international level, EFSA concluded that the intended uses will not trigger a revision of the existing MRLs for commodities of animal origin.
3. Consumer risk assessment
The consumer risk assessment was performed with revision 2 of the EFSA Pesticide Residues Intake Model (PRIMo). This exposure assessment model contains the relevant European food consumption data for different subgroups of the EU population (EFSA, 2007).
The estimated exposure was then compared with the acceptable daily intake (ADI) of 0.04 mg/kg body weight (bw) per day and the acute reference dose (ARfD) of 0.25 mg/kg bw derived for sulfoxaflor (European Commission, 2015). The EU pesticides peer review agreed to apply the toxicological reference values of the parent to the metabolite X11719474 (EFSA, 2014).
The most recent long‐term exposure assessment performed by EFSA (EFSA, 2017) was updated with the median residue values (STMR) derived from the residue trials submitted in support of this MRL application. The short‐term exposure was conducted only with regards to the crops under consideration, using the highest and median values in accordance with the internationally agreed methodology. The input values used for the dietary exposure calculation are summarised in Appendix D.
No long‐term intake concerns were identified for any of the European diets incorporated in the EFSA PRIMo. The estimated long‐term dietary intake was in the range of 1.5–12% of the ADI (NL children diet). The contribution of the residues expected in the crops under consideration to the total exposure accounted individually for a maximum of 0.2% of ADI (rye). The short‐term exposure did not exceed the ARfD for any the crops considered in this application.
In the EU pesticides peer review, a theoretical factor of 2 was applied to the risk assessment in order to accommodate for the lack of information on the ratio of the enantiomers present in the individual diastereomers of sulfoxaflor and X11719474 (EFSA, 2014). Following this approach, the margin of safety of the exposure calculation is still sufficiently large to conclude that the assessed uses are unlikely to present a consumer health concern.
For further details on the exposure calculations, a screenshot of the Report sheet of the PRIMo is presented in Appendix C.
4. Conclusion and Recommendations
The data submitted in support of this MRL application were found to be sufficient to derive MRL proposals for limes, cauliflowers, Brussels sprouts, kales, spinaches and similar leaves, herbs and edible flowers, beans without pods, peas with pods, oat, rye and triticale (wheat). EFSA concluded that the use of sulfoxaflor according to the intended good agricultural practices is unlikely to present a risk to consumers’ health.
