Abstract

In accordance with Article 6 of Regulation (EC) No 396/2005, the applicant BASF SE submitted a request to the competent national authority in the Netherlands to modify the existing maximum residue levels (MRLs) for bentazone in beans and peas with and without pods. The data submitted in support of the request were found to be sufficient to derive MRL proposals for peas with pods. Results from the residue trials indicated that there is no need to modify the existing MRLs for beans with pods, beans without pods and peas without pods. Adequate analytical methods for enforcement are available to control the residues of bentazone and its metabolites in the commodity under consideration at the validated limit of quantification (LOQ) of 0.01 mg/kg. EFSA concluded that the proposed use of bentazone on peas with pods will not result in a consumer exposure exceeding the toxicological reference values and therefore is unlikely to pose a risk to consumers’ health for parent bentazone. The risk assessment however is indicative and affected by additional, non‐standard uncertainties resulting from the insufficient information related to the toxicological properties for 6‐hydroxy‐bentazone in the wheat metabolism study.

Summary

In accordance with Article 6 of Regulation (EC) No 396/2005, BASF SE submitted an application to the competent national authority in the Netherlands (evaluating Member State, EMS) to modify the existing maximum residue levels (MRLs) for the active substance bentazone in beans and peas with and without pods. 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 19 July 2020. To accommodate for the intended uses of bentazone, the EMS proposed to raise the existing MRLs from 0.3 to 0.4 mg/kg in beans and peas with pods and from 0.05 to 0.15 in beans and peas without pods, respectively.

EFSA assessed the application and the evaluation report as required by Article 10 of the MRL regulation. EFSA identified points which needed further clarification, which were requested from the EMS and the applicant. On 21 September 2020 the applicant submitted the requested clarification.

Based on the conclusions derived by EFSA in the framework of the renewal of approval under 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 bentazone following foliar application was investigated in crops belonging to the groups of root crops, cereals and pulses/oilseeds. Metabolic patterns in the different studies were shown to be similar and the MRL review concluded on a residue for enforcement and risk assessment in all plant commodities as the sum of bentazone and the conjugates of metabolites 6‐hydroxy‐bentazone and 8‐hydroxy‐bentazone, expressed as bentazone. The metabolism of bentazone in rotational crops (radish, lettuce and wheat) indicated that a specific residue definition is not necessary for rotational crops. In the framework of the European Union (EU) pesticides peer review, a significant unidentified fraction (M3) was found in an additional metabolism study with wheat and further attempts for identification of M3 were considered necessary. New information on the identity of fraction M3 has not been provided to EFSA. The lack of this information is not expected to affect specifically the current assessment as the forages of beans and peas with and without pods are not used as livestock feed in Europe.

Based on the metabolic pattern identified in metabolism studies and the toxicological significance of metabolites, the peer review on the renewal of the approval proposed ‘bentazone’ as the relevant residue for enforcement. For the risk assessment, a residue definition was provisionally proposed as ‘sum of bentazone, 6‐hydroxy‐bentazone and its conjugates, expressed as bentazone’.

As the residue definitions derived by the peer review are not yet enforced, EFSA derived MRL proposals for the enforcement residue definition established in the Regulation (EC) No 396/2005 (sum of bentazone, its salts, 6‐hydroxy‐bentazone (free and conjugated) and 8‐hydroxy‐bentazone (free and conjugated), expressed as bentazone). Anticipating possible implementation of the residue definition for enforcement proposed in the framework of the EU pesticides peer review, EFSA derived also MRL proposals based on the residue definition restricted to parent bentazone. The risk assessment was performed for the residue definition proposed in the MRL review that comprises in addition to 6‐hydroxy‐bentazone (free and conjugated) also 8‐hydroxy‐bentazone (free and conjugated), which is considered to give a more conservative result.

Sufficiently validated analytical methods based on liquid chromatography with tandem mass spectrometry (LC–MS/MS) are available to quantify residues in the crops assessed in this application according to the enforcement residue definition. The methods enable quantification of each individual analyte at or above 0.01 mg/kg in the crops assessed (limit of quantification (LOQ)).

The available residue trials are sufficient to derive an MRL proposal of 0.8 mg/kg for peas with pods based on the more critical southern Europe (SEU) use. Results from the residue trials submitted indicated that there is no need to modify the existing MRLs for beans with pods, beans without pods and peas without pods.

Specific studies investigating the nature (hydrolysis studies) and magnitude of bentazone and its relevant metabolites in processed commodities are currently not required, as the total theoretical maximum daily intake (TMDI) is below the trigger value of 10% of the acceptable daily intake (ADI).

The occurrence of bentazone residues in rotational crops was investigated in the framework of the EU pesticides peer review and the MRL review. Based on the available information, it was concluded that significant residue levels are unlikely to occur in rotational crops, provided that the active substance is used according to the proposed Good Agricultural Practice (GAP).

Residues of bentazone in commodities of animal origin were not assessed since the crops under consideration in this MRL application are normally not fed to livestock.

The toxicological profile of bentazone, 6‐hydroxy‐bentazone and 8‐hydroxy‐bentazone was assessed during the renewal of the approval process of bentazone. New toxicological reference values were derived for bentazone as an ADI of 0.09 mg/kg body weight (bw) per day and an acute reference dose (ARfD) of 1 mg/kg bw. The peer review also concluded that the reference values of the parent can be applied to the metabolite 8‐hydroxy‐bentazone. Regarding the 6‐hydroxy‐bentazone metabolite, insufficient toxicological information on the general toxicity was available to draw a final conclusion whether the toxicological reference values of the parent bentazone are applicable also to the metabolite 6‐hydroxy‐bentazone. No new information has been submitted with the MRL application. Hence, EFSA performed an indicative dietary risk assessment assuming that the toxicity of the metabolite 6‐hydroxy‐bentazone is comparable to the parent compound.

The consumer risk assessment was performed with revision 3.1 of the EFSA Pesticide Residues Intake Model (PRIMo). The long‐term exposure assessment was performed taking into account the STMR value derived from the residue trials on peas with pods leading to a new MRL proposal. The other input values selected were the risk assessment values derived by EFSA in previous opinions and corresponding to the MRLs as established in the MRL Regulation. Commodities for which no uses were reported in the MRL review and for which the MRL was implemented at the LOQ following the MRL review due to lack of residue data, were excluded from the exposure calculation. The acute exposure assessment was performed only for peas with pods leading to the new MRL proposal, considering the highest residue value derived from the residue trials submitted. An update of the consumer risk assessment for beans with and without pods and peas without pods was not necessary. The conclusion reached in the previously performed consumer risk assessments is still valid.

EFSA concluded that the proposed use of bentazone on peas with pods will not result in a consumer exposure exceeding the toxicological reference values and therefore is unlikely to pose a risk to consumers’ health for parent bentazone. The risk assessment however is indicative and affected by additional, non‐standard uncertainties resulting from insufficient information related to the toxicological properties for 6‐hydroxy‐bentazone.

EFSA proposes to amend the existing MRLs as reported in the summary table below.

Assessment

The European Food Safety Authority (EFSA) received an application to modify the existing maximum residue level (MRL) for bentazone in beans and peas with and without pods. The detailed description of the intended uses of bentazone, which are the basis for the current MRL application, is reported in Appendix A.

Bentazone is the ISO common name for 3‐isopropyl‐1H‐2,1,3‐benzothiadiazin‐4(3H)‐one 2,2‐dioxide (IUPAC name). Bentazone is formulated and used as the sodium salt. The chemical structures of the active substance and its main metabolites are reported in Appendix E.

Bentazone was evaluated for renewal of the approval in the framework of Regulation (EC) No 1107/20091 with the Netherlands designated as rapporteur Member State (RMS) for the representative uses as a foliar treatment on a variety of crops. The renewal assessment report (RAR) prepared by the RMS has been peer reviewed by EFSA (2015). The decision on the renewal of bentazone entered into force on 1 June 2018.2

The EU MRLs for bentazone are established in Annex II of Regulation (EC) No 396/20053. The review of existing MRLs according to Article 12 of Regulation (EC) No 396/2005 (MRL review) has been performed (EFSA, 2012) and the proposed modifications have been implemented in the MRL legislation. After completion of the MRL review, EFSA has issued one reasoned opinion on the evaluation of confirmatory data following the Article 12 MRL review for bentazone (EFSA, 2019b) and one reasoned opinion on the modification of MRLs for bentazone (EFSA, 2019c). The proposals from these reasoned opinions have been considered in recent MRL regulations.4

In accordance with Article 6 of Regulation (EC) No 396/2005, BASF SE submitted an application to the competent national authority in the Netherlands (evaluating Member State, EMS) to modify the existing MRLs for the active substance bentazone in beans and peas with and without pods. 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 19 July 2020. To accommodate for the intended uses of bentazone, the EMS proposed to raise the existing MRLs from 0.3 to 0.4 mg/kg in beans and peas with pods and from 0.05 to 0.15 mg/kg in beans and peas without pods.

EFSA assessed the application and the evaluation report as required by Article 10 of the MRL regulation. EFSA identified points which needed further clarification, which were requested from the EMS and the applicant. On 21 September 2020 the applicant submitted the requested clarification.

EFSA based its assessment on the evaluation report submitted by the EMS (Netherlands, 2020), the renewal assessment report (RAR) and its addenda (Netherlands, 2013, 2015) prepared under Regulation (EC) 1107/2009, the conclusion on the peer review of the pesticide risk assessment of the active substance bentazone (EFSA, 2015), the Commission review report on bentazone (European Commission, 2018), the reasoned opinion on MRL review according to Article 12 of Regulation (EC) No 396/2005 and of its confirmatory data (EFSA, 2012, 2019b), as well as the conclusions from a previous EFSA opinion on bentazone (EFSA, 2019c).

For this application, the data requirements established in Regulation (EU) No 544/20115 and the guidance documents applicable at the date of submission of the application to the EMS are applicable (European Commission, 1997a, 1997b, 1997c, 1997d, 1997e, 1997f, 1997g, 2000, 2010a, 2010b, 2017; OECD, 2011). 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 546/20116.

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, is presented in Appendix B.

The evaluation report submitted by the EMS (Netherlands, 2020) 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 bentazone in primary crops belonging to the groups of root and tuber crops (potatoes), cereals/grass (rice, maize, wheat) and pulses/oilseeds (soya beans, green beans) following foliar application has been investigated in the framework of the MRL review (EFSA, 2012) and the EU pesticides peer review (EFSA, 2015).

Parent bentazone was extensively metabolised in plants. It was rarely detected in any crop part (maximum 8% of the total radioactive residues (TRR)), except in wheat forage and straw (up to 56% TRR). The metabolite 6‐hydroxy‐bentazone in its conjugated form was identified in significant proportions, mainly in the feed commodities (24% TRR in maize forage and up to 41% TRR in wheat hay), whilst the glucoside conjugate of the 8‐hydroxy‐bentazone metabolite was detected in soya bean forage and in wheat straw, but at lower levels (28% TRR and 3% TRR, respectively). A major part of the radioactivity in the soya bean seeds, potato tuber and cereal grain was found to be incorporated into natural plant constituents (up to 70% TRR).

The results of new metabolism studies on foliar treated potato and wheat assessed in the EU pesticides peer review provided additional information on the metabolic pathway of bentazone (EFSA, 2015). In potato tubers, numerous fractions above the 10% TRR were recovered, which were not further identified as their actual levels were mostly below 0.01 mg eq/kg and because consisted mainly of a mixture of polar compounds. In wheat straw, a significant unidentified fraction M3 was found (57% TRR; 1.1 mg eq/kg) and further attempts for identification were considered necessary in the EU pesticides peer review.

The metabolic pathway of bentazone in plants consisted mainly of hydroxylation of the parent molecule to form the metabolites 6‐hydroxy‐bentazone and 8‐hydroxy‐bentazone, followed by an O‐glycosylation conjugation step (EFSA, 2015).

For the intended uses, the metabolic behaviour in primary crops is sufficiently addressed.

1.1.2. Nature of residues in rotational crops

Beans and peas can be grown in rotation with other crops. During the renewal of the approval of bentazone (EFSA, 2015), the studies investigating the rate of degradation of bentazone in soil were assessed, indicating faster degradation of bentazone under field conditions (DT90 of 87 days) than under laboratory conditions (DT90 of 163 days). In soil a minor metabolite (N‐methyl‐bentazone, 2.4–5.7% of applied radioactivity (AR)) was identified, which exhibits higher persistence in soil than the parent bentazone (DT90 up to 508 days). A detailed assessment of the nature of bentazone residues in rotational crops is therefore considered relevant.

The metabolism of bentazone in rotational crops was investigated in the framework of the MRL review (EFSA, 2012) and the EU pesticides peer review for the renewal of the approval of bentazone (EFSA, 2015). In the confined rotational crop metabolism studies on leafy crops, root crops and cereals after a bare soil application of 14C‐phenyl‐labelled bentazone, the radioactive residues were characterised as polar fractions which were further incorporated into the natural compounds of the plant tissues (30% of TRR in wheat straw, up to 75% of TRR in wheat grain).

An additional metabolism study with foliar‐treated wheat, grown as a rotational crop following the harvest of potatoes as primary crop previously treated with bentazone, was submitted in the framework of the renewal of the approval (EFSA, 2015). Wheat was either treated by foliar spraying with bentazone (1.5 kg/ha) or left untreated to assess the uptake from the soil as rotational crop. In wheat straw, a significant fraction (M3) (57% TRR, 1.1 mg eq/kg) was not identified. The EU pesticides peer review requested to characterise and identify this fraction (data gap). New information related to the identity of the fraction M3 has not been provided in the framework of the current MRL application. The lack of this information is not expected to specifically affect the current assessment as forages of beans and peas are not used as livestock feed in Europe. However, EFSA reiterates that the data gap on the identity of the metabolite fraction M3 flagged in the renewal of approval is still open. Pending the clarification of this open issue, it cannot be excluded that in crops unidentified residues resulting from the uptake form the soil might occur.

The peer review concluded that a specific residue definition for rotational crops was not deemed necessary. However, the residue definition for risk assessment was provisionally proposed, pending on the clarification with regard to the identity of fraction M3 in wheat straw (EFSA, 2015).

1.1.3. Nature of residues in processed commodities

Standard hydrolysis studies with bentazone and its relevant metabolites representative for pasteurisation, boiling/cooking and sterilisation are not available. Such studies are not required, considering the low consumer exposure to bentazone residues resulting from the crops under assessment.

1.1.4. Methods of analysis in plants

Analytical methods for the determination of bentazone residues were assessed in the framework of the MRL review and the EU pesticides peer review for renewal of the approval of bentazone (EFSA, 2012, 2015). The methods are sufficiently validated for residues of bentazone, 6‐hydroxy‐bentazone and 8‐hydroxy‐bentazone (free and conjugated) in plant matrices with high water content (onions, peas), high acid content (orange), high oil content (soya beans), dry/high protein content (dry peas) and dry/high starch content (maize grains) at the individual limits of quantification (LOQs) of 0.01 mg/kg (EFSA, 2015). The combined LOQ is 0.03 mg/kg.

The QuEChERS method in combination with high‐performance liquid chromatography with tandem mass spectrometry (HPLC–MS/MS) is also available to dose the parent bentazone only with an LOQ of 0.005 mg/kg in high water content matrices (EFSA, 2012).

Thus, a sufficiently validated enforcement method is available for the determination of bentazone residues according to the current enforcement residue definition in beans and peas with and without pods (high water content matrices). The method includes a hydrolysis step to cover compounds included in the residue definition currently established in Regulation (EC) No 396/2005.

1.1.5. Storage stability of residues in plants

The storage stability of bentazone and 6‐hydroxy‐bentazone and 8‐hydroxy‐bentazone metabolites in plant matrices stored under frozen conditions was investigated in the framework of the EU pesticides peer review (EFSA, 2015). These studies demonstrated that bentazone, 6‐hydroxy‐bentazone and 8‐hydroxy‐bentazone are stable for 2 years in high water content matrices (maize green plants), dry/high starch matrices (maize grain), dry/high protein matrices (pea seed) and high oil content matrices (linseed seed).

1.1.6. Proposed residue definitions

Based on the metabolic pattern identified in metabolism studies, the toxicological significance of metabolites and the capabilities of enforcement analytical methods, the following residue definitions were initially proposed by the MRL review for plant products (EFSA, 2012):

  • Residue definition for both risk assessment and enforcement: Sum of bentazone and the conjugates of 6‐hydroxy‐bentazone and 8‐hydroxy‐bentazone, expressed as bentazone.

In Regulation (EC) No 396/2005, a slightly modified enforcement residue definition was established: Bentazone (Sum of bentazone, its salts, 6‐hydroxy‐bentazone (free and conjugated) and 8‐hydroxy‐bentazone (free and conjugated), expressed as bentazone).

However, in the framework of the renewal of the approval, the peer review concluded on the following residue definitions for all plant commodities after foliar applications (EFSA, 2015):

  • residue definition for enforcement: Bentazone

  • residue definition for risk assessment: Sum of bentazone, 6‐hydroxy‐bentazone and its conjugates, expressed as bentazone7 (provisional).

These residue definitions were proposed for primary crops and rotational crops.

Considering the new information provided, the EU pesticides peer review agreed on parent alone for enforcing bentazone residues, even though in pulses/oilseeds and in cereal grains the parent compound was hardly ever detected. The 8‐hydroxy‐bentazone metabolite generally occurred at low levels in crops (around the LOQ) and was excluded from the residue definition for risk assessment. The enforcement residue definition for plant commodities as proposed by the EU pesticides peer review is equivalent with the residue definition derived by the JMPR (EFSA, 2015).

Since a formal decision on the revision of the enforcement residue definition has not been taken, the residue definition implemented in Regulation (EC) No 396/2005 is relevant for the current application and MRL proposals are derived for the residue definition covering the sum of bentazone and 6‐hydroxy‐bentazone (free and conjugated) and 8‐hydroxy‐bentazone (free and conjugated), expressed as bentazone. Anticipating possible implementation of the residue definition for enforcement proposed in the framework of the EU pesticides peer review, EFSA derived also MRL proposals based on the residue definition restricted to parent bentazone.

1.2. Magnitude of residues in plants

1.2.1. Magnitude of residues in primary crops

In support of this MRL application, the applicant submitted several residue trials performed in beans and peas with and without pods. A number of trials were conducted in the same location as side‐by‐side trials with and without the use of an adjuvant as foreseen in the GAP. In some cases, the residue values were higher with the presence of this adjuvant but in other cases residue values were higher for the treatment without adjuvant. The results of the trials compliant with the intended GAPs are reported in Appendix B (Table B.1.2.1). Results from trials with or without adjuvant were reported separately and combined. When combined, the highest residue value from the side‐by‐side trials was selected.

The samples were analysed for the parent compound and the metabolites included in the residue definitions for enforcement and risk assessment. Residues of metabolite 8‐hydroxy‐bentazone were always below or at the LOQ, except in one sample (0.012 mg/kg); residues of 6‐hydroxy‐bentazone ranged from < LOQ of 0.01 to 0.11 mg/kg with a sample at 0.34 mg/kg. According to the assessment of the EMS, the analytical methods used were sufficiently validated and fit for purpose (Netherlands, 2020). The samples of these residue trials were stored under conditions for which integrity of the samples has been demonstrated.

Beans and peas with pods

For beans with pods (major crop), the applicant provided eight residue trials from the northern Europe (NEU) and eight residue trials from the southern Europe (SEU). EFSA noted that all residue trials performed in NEU are independent and compliant with the intended GAP, while in two out of eight residue trials performed in the SEU (Trial L110251‐05/06) the product was applied at a later growth stage than in the intended GAP (application at BBCH 25‐60 vs the intended BBCH 12‐25). EFSA disregarded these two trials as incompliant with the intended GAP, also noting that, the residues in beans from these trials were higher than in the remaining trials, indicating that later application affects the residue levels in the crop. Therefore, EFSA considers that for the SEU use the minimum number of trials required is not met. At least two additional independent and GAP‐compliant residue trials should be submitted since beans with pods is a major crop for which at least eight residue trials are required according to the EU extrapolation guidance (European Commission, 2017).

EFSA concludes that only the NEU use is sufficiently supported by residue trials to derive an MRL proposal of 0.06 mg/kg, which is however lower than the existing EU MRL (0.3 mg/kg) and therefore no MRL modification would be required. Individual results from the four NEU trials conducted with an adjuvant in the formulation showed to be on the same order of magnitude of the trials conducted without adjuvant.

The intended SEU use was not supported by a sufficient number of residue trials in beans with pods. Beans with pods is a major crop and a minimum of eight trials are required to derive an MRL proposal. Although extrapolation from residue data in peas with pods to beans with pods is possible and the GAPs are comparable (European Commission, 2017), the number of trials on peas with pods available is not sufficient to support the extrapolation.

For peas with pods (minor crop), the applicant provided eight independent residue trials from the NEU and four independent residue trials from the SEU. EFSA noted that for two out of eight residue trials performed in the NEU the product was applied at a growth stage which is not in line with the intended GAP (application at BBCH 51 vs the intended BBCH 12‐25). However, despite the deviation from the intended GAP, these trials were performed at a growth stage where the edible part was not formed yet (BBCH 51: first flower buds visible) and resulted in residue levels below the LOQ. Therefore, EFSA considered the deviation from the BBCH stage at application acceptable in this case and agreed with the EMS to include them in the MRL calculation.

Regarding the trials conducted in the SEU, EFSA further noted that one trial (Trial A/SF/H/07/163 with adjuvant and trial A/SF/H/07/140 without adjuvant) resulted in significant higher level of residues. The applicant investigated possible deviations with this trial but concluded that all parameters were appropriate, there was no evidence of misapplication, improper sampling or contamination and product was applied and sample collected at appropriate growth stage (BBCH 14 and 79, respectively). However, in this trial, peas with pods were collected 31 days after the application. The applicant indicated that this is a relatively short interval to transition from BBCH 14 to 79 and this was the shortest PHI in the study despite the fact that the weather condition was not unusual and the peas variety was not fast‐growing. The applicant concluded that, since no other discrepancy than short PHI was noted, the high value should not be disregarded as the trial is compliant with the intended GAP. EFSA agrees with this conclusion for such a minor crop and also considering that peas with pods could be consumed even at an immature growth stage.

EFSA derived an MRL of 0.8 mg/kg based on SEU use. Sufficient evidence that the use in NEU is less critical for residues is provided.

EFSA noted that the EMS proposed to pool together the NEU residue trials on beans and peas with pods to derive an MRL proposal of 0.08 mg/kg and the SEU residue trials on beans and peas with pods to derive an MRL proposal of 0.5 mg/kg (the proposal includes the two SEU residue trials on beans which shall be disregarded because not‐compliant). Finally, the EMS combined all the residue trials on beans and peas with pods from each zone together proposing an MRL of 0.4 mg/kg (Netherlands, 2020). EFSA acknowledge that according to the extrapolation guidance residues from beans can be extrapolated to peas (and vice versa) and may be extrapolated to the whole group of legume vegetables if the application is made before the forming of the edible part of the plant. However, the extrapolation is acceptable only if the minimum number of trials required per each individual crop and per zone is available.

Beans and peas without pods

For beans without pods (minor crop), the applicant provided seven residue trials in NEU and six residue trials in SEU. EFSA noted that all residue trials performed in NEU and SEU are independent and compliant with the intended GAP and all result in residue levels below the LOQ.

For peas without pods (major crop), the applicant provided eight independent residue trials in NEU and only four residue trials in SEU. EFSA noted that for two out of eight residue trials performed in the NEU the product was applied at a growth stage which is not in line with the intended GAP (application at BBCH 51 vs the intended BBCH 12‐25). However, despite the deviation from the intended GAP, these trials were performed at a growth stage where the edible part was not formed yet (even before the flowering stage) and resulted in residue levels below the LOQ. Therefore, EFSA considered the deviation from the application rate acceptable in this case and agreed with the EMS to include them in the MRL calculation.

While regarding the residue trials in the SEU, the applicant has provided only four residue trials, whereas, according to the EU extrapolation guidance, peas without pods is a major crop for which at least eight GAP‐compliant residue trials should be submitted (European Commission, 2017). The number of trials conducted on beans without pods in the SEU (total of six) is not sufficient to derive an MRL proposal for the intended use on peas without pods by extrapolation (European Commission, 2017).

Therefore, considering the insufficient number of trials provided, EFSA considers residues data in SEU not sufficient for a major crop like peas without pods and derived MRL only based on residue levels of NEU trials, resulting in levels below the LOQ.

EMS proposed to pool together the NEU residue trials on beans and peas without pods to derive an MRL proposal of < 0.03 mg/kg and the SEU residue trials on beans and peas without pods to derive an MRL proposal of 0.15 mg/kg (including the four SEU residue trials on peas which are not sufficient for such a major crop). Finally, the EMS combined all the residue trials on beans and peas without pods from each zone together proposing an MRL of 0.15 mg/kg (Netherlands, 2020). EFSA acknowledge that according to the extrapolation guidance residues from beans can be extrapolated to peas (and vice‐versa) and may be extrapolated to the whole group of legume vegetables if the application is made before the forming of the edible part of the plant. However, the extrapolation is acceptable only if the minimum number of trials required per each individual crop and per zone is available, which is not the case here.

1.2.2. Magnitude of residues in rotational crops

The studies on the magnitude of bentazone residues in rotational crops were investigated in the framework of the peer review (EFSA, 2015). Bentazone was applied on soya beans twice at 1.12 kg/ha and various rotational crops (alfalfa, corn, lettuce, mustard, radishes, snap beans, sugar beets, spinach, etc.) were planted at different plant‐back intervals (PBI), corresponding to crop failure, autumn and annual rotation. The highest residues in succeeding crops ranged from 0.01 to 0.019 mg/kg in radishes, mustard, turnip and spinach planted 16‐30 DAT. In the remaining rotational crops at the longer PBI, residues of bentazone, 6‐hydroxy‐bentazone and 8‐hydroxy‐bentazone were below the individual LOQs of 0.01 mg/kg.

The EU pesticides peer review concluded that residues above 0.01 mg/kg are not expected to occur in rotational crops, provided that bentazone is applied in compliance with representative uses (EFSA, 2015). Since the intended use on beans and peas with and without pods is less critical compared to the representative uses, the same conclusion is valid for the current assessment.

1.2.3. Magnitude of residues in processed commodities

Specific processing studies investigating residues in cooked and canned legumes were not submitted with this application and are not required as the total TMDI is below the trigger value of 10% of the acceptable daily intake (ADI).

1.2.4. Proposed MRLs

The available data are considered sufficient to derive MRL proposals as well as risk assessment values for the commodities under evaluation.

For beans with pods, only the NEU use is sufficiently supported by residue trials to derive an MRL of 0.06 mg/kg, which is, however, lower than the existing EU MRL (0.3 mg/kg) and therefore no MRL modification would be required. While for peas with pods both NEU and SEU are sufficiently supported by residue trials to derive an MRL of 0.09 mg/kg based on NEU trials and an MRL of 0.8 mg/kg based on SEU trials.

For beans without pods, both NEU and SEU are sufficiently supported by residue trials to derive an MRL proposal at the LOQ of 0.03 mg/kg, which is however lower than the existing EU MRL (0.05 mg/kg) and therefore no MRL modification would be required. While for peas without pods only the NEU use is sufficiently supported by residue trials to derive an MRL proposal at the LOQ of 0.03 mg/kg, which is also lower than the existing EU MRL (0.05 mg/kg) and therefore no MRL modification would be required as well.

Anticipating possible implementation of the residue definition for enforcement proposed in the framework of the EU pesticides peer review, EFSA derived also MRL proposals based on the residue definition limited to bentazone (see Table B.1.2.1).

In Section 3 EFSA assessed whether residues on these crops resulting from the intended uses are likely to pose a consumer health risk.

2. Residues in livestock

Not relevant as beans and peas with and without pods are not used for feed purposes.

3. Consumer risk assessment

EFSA performed the dietary risk assessment using revision 3.1 of the EFSA PRIMo (EFSA, 2018, 2019a). This exposure assessment model contains food consumption data for different sub‐groups of the EU population and allows the acute and chronic exposure assessment to be performed in accordance with the internationally agreed methodology for pesticide residues.

The toxicological reference values for bentazone used in the risk assessment (i.e. ADI of 0.09 mg/kg body weight (bw) per day and the acute reference dose (ARfD) value of 1 mg/kg bw) were derived in the framework of the EU pesticides peer review (European Commission 2018). The EU pesticides peer review concluded that 8‐hydroxy‐bentazone is less toxic than the parent bentazone and the reference values of the parent can be applied for this metabolite.

Regarding the 6‐hydroxy‐bentazone metabolite, insufficient toxicological information was available, and a data gap has been identified by the peer review for further data to derive toxicological reference values (EFSA, 2015). In a previous MRL application, the genotoxicity potential of this metabolite has been clarified with a QSAR analysis and read across. However, EFSA was of the opinion that the general toxicity of the metabolite could not be concluded on the basis of the information provided (EFSA, 2019b). No new information has been submitted with this MRL application. Lacking a final conclusion on the toxicological profile for the metabolite 6‐hydroxy‐bentazone, the risk assessment is indicative, as it was performed under the assumption that the toxicity of the metabolite 6‐hydroxy‐bentazone is comparable to the parent compound.

Finally, as the residue definition derived by the peer review is not yet enforced, the risk assessment was performed with the residue definition proposed during the MRL review which comprises also 8‐hydroxy‐bentazone (free and conjugated). The assessment is considered to give a more conservative result.

Short‐term (acute) dietary risk assessment

The short‐term exposure assessment was performed only for peas with pods in accordance with the internationally agreed methodology (FAO, 2016). The calculations were based on the HR derived from supervised field trials and the complete list of input values can be found in Appendix D.1. The short‐term exposure was low as well (maximum 0.3% of the ARfD).

Long‐term (chronic) dietary risk assessment

In the framework of the MRL review a comprehensive long‐term consumer exposure to residues arising in food from the existing EU uses of bentazone was performed (EFSA, 2012) and revised twice (EFSA, 2019b,c). The calculation was updated with the median residue value (STMR) derived for peas with pods from the residue trials assessed in this application. The input values for the exposure assessment were the risk assessment values derived by the EFSA and corresponding to the MRLs as established in the MRL Regulation (EU) No 2020/1633. The complete list of input values is presented in Appendix D.1.

Under this assumption that the toxicity of metabolite 6‐hydroxy‐bentazone is covered by the reference values of the parent compound, the estimated maximum long‐term dietary intake accounted for maximum 3% of the ADI (NL toddler). The contribution of residues in peas with pods to the overall long‐term exposure was very low (maximum 0.01% of the ADI).

An update of the acute and chronic consumer risk assessment for the intended uses on beans with and without pods and peas without pods was deemed not necessary. The conclusion reached in the previously performed consumer risk assessments is still valid (EFSA, 2012, 2019b,c).

The risk assessment is affected by additional, non‐standard uncertainties resulting from the lack of toxicological data related to the metabolite 6‐hydroxy‐bentazone and the unidentified metabolite fraction M3 in the wheat metabolism study. When taking a decision on the acceptability of the MRL proposal derived for peas with pods from these residue trials, risk managers should take into account the additional non‐standard uncertainties.

The results of the consumer risk assessment calculation are summarised in Appendix B.3.

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 the request were found to be sufficient to derive MRL proposals for peas with pods. Results from the residue trials indicated that there is no need to modify the existing MRLs for beans with pods, beans without pods and peas without pods.

EFSA concluded that the proposed use of bentazone on peas with pods will not result in a consumer exposure exceeding the toxicological reference values and therefore is unlikely to pose a risk to consumers’ health for parent bentazone. The risk assessment however is indicative and affected by additional, non‐standard uncertainties resulting from the insufficient information related to the toxicological properties for 6‐hydroxy‐bentazone.

In Appendix B.4, the overall EFSA recommendations are reported.

The residue definition was considered provisional, due to an insufficient characterisation of the metabolite fraction (referred to as fraction M3) found in the primary crop metabolism study in wheat (wheat straw). Furthermore, the data to characterise the toxicological properties of 6‐hydroxy‐bentazone were not sufficient. Once the missing studies are made available, the provisional residue definition should be reviewed and if relevant, the existing MRLs for bentazone need to be reconsidered.
