Abstract

In August 2022, the European Commission asked EFSA to provide a statement on the available outcomes of the assessment of environmental fate and behaviour and ecotoxicology drawn in the context of the pesticides peer review for the renewal of approval of the active substance dimoxystrobin conducted in accordance with Commission Implementing Regulation (EC) No 844/2012. The current statement contains the conclusions of the assessments related to environmental fate and behaviour and ecotoxicology finalised following the pesticides peer review expert discussions held in January and June 2022. The concerns identified are presented.

Keywords: dimoxystrobin, pesticide, fungicide, peer review, environmental fate and behaviour, ecotoxicology assessment

Summary

Dimoxystrobin is an active substance covered by the third stage of the renewal programme for pesticides (‘AIR3’) in accordance with Commission Implementing Regulation (EU) No 844/2012.

An application for the renewal of approval of the active substance dimoxystrobin followed by the submission of the supplementary dossiers in July 2015 was made by BASF SE to the rapporteur Member State (RMS), Hungary, and the co‐rapporteur Member State (co‐RMS), Ireland.

An initial evaluation of the dossiers was provided by the RMS in the Renewal Assessment Report (RAR) which was submitted to EFSA in September 2017. Subsequently, EFSA initiated a peer review of the pesticides risk assessment on the RMS evaluation in line with the provisions of Commission Implementing Regulation (EU) No 844/2012.

Following the completion of a commenting period, including a public consultation on the RAR, EFSA requested the applicant to provide certain additional information under the stop the clock procedure in accordance with Article 13(3) of Regulation (EU) No 844/2012, which was evaluated by Hungary and incorporated into an updated RAR. Subsequently, in January 2022, meetings of experts from EFSA and Member States took place to discuss certain elements related to mammalian toxicology, environmental fate and behaviour and ecotoxicology. In addition, in June 2022, follow‐up meetings of experts from EFSA and Member States took place to further discuss elements related to mammalian toxicology and ecotoxicology.

In August 2022, prior to completion of the peer review process, EFSA was mandated by the European Commission to provide a statement on the available outcomes of the assessment of environmental fate and behaviour and ecotoxicology drawn in the context of the peer review of dimoxystrobin.

The present statement contains the finalised conclusions of the assessments related to environmental fate and behaviour and ecotoxicology following the pesticides peer review expert discussions in those areas held in January and June 2022.

The data available on environmental fate and behaviour were sufficient to carry out the required environmental exposure assessments at EU level for the representative uses. A critical area of concern with respect to point 3.10 of Annex II to Regulation (EC) No 1107/2009 was identified in relation to the potential for groundwater contamination by the relevant metabolites.

In the area of ecotoxicology, a high risk was identified for aquatic organisms leading to a critical area of concern. In addition, the risk assessment for honeybee larvae could not be finalised.

1. Introduction

Dimoxystrobin is an active substance covered by the third stage of the renewal programme for pesticides (‘AIR3’) in accordance with Commission Implementing Regulation (EU) No 844/2012 1 .

Commission Implementing Regulation (EU) No 844/2012, as amended by Commission Implementing Regulation (EU) No 2018/1659 2 (hereinafter referred to as ‘the Regulation’), lays down the provisions for the procedure of the renewal of the approval of active substances, submitted under Article 14 of Regulation (EC) No 1107/2009 3 . This regulates for the European Food Safety Authority (EFSA) the procedure for organising the consultation of Member States, the applicant(s) and the public on the initial evaluation provided by the rapporteur Member State (RMS) and/or co‐rapporteur Member State (co‐RMS) in the renewal assessment report (RAR), and the organisation of an expert consultation where appropriate.

In accordance with Article 13 of the Regulation, unless formally informed by the European Commission that a conclusion is not necessary, EFSA is required to adopt a conclusion on whether the active substance can be expected to meet the approval criteria provided for in Article 4 of Regulation (EC) No 1107/2009 within 5 months from the end of the period provided for the submission of written comments, subject to an extension of an additional 3 months where additional information is required to be submitted by the applicant(s) in accordance with Article 13(3). Furthermore, in accordance with Article 13(3a), where the information available in the dossier is not sufficient to conclude the assessment on whether the approval criteria for endocrine disruption are met, additional information can be requested to be submitted in a period of minimum 3 months, not exceeding 30 months, depending on the type of information requested.

In accordance with Article 1 of the Regulation, an application for the renewal of approval of the active substance dimoxystrobin followed by the submission of the supplementary dossiers in July 2015 was made by BASF SE to the rapporteur Member State (RMS), Hungary, and the co‐rapporteur Member State (co‐RMS), Ireland. The RMS provided its initial evaluation of the dossier on dimoxystrobin in the RAR, which was received by EFSA on 1 September 2017 (Hungary, 2017).

In accordance with Article 12 of the Regulation, EFSA distributed the RAR to the Member States and the applicant, BASF SE, for consultation and comments on 21 February 2019. EFSA also provided comments. In addition, EFSA conducted a public consultation on the RAR. EFSA collated and forwarded all comments received to the European Commission on 26 April 2019. At the same time, the collated comments were forwarded to the RMS for compilation and evaluation in the format of reporting table. In addition, the applicant was invited to respond to the comments received. The comments and the applicant's response were evaluated by the RMS in column 3 of the reporting table.

The need for expert consultation and the necessity for additional information to be submitted by the applicant in accordance with Article 13(3) of the Regulation were considered in a telephone conference between EFSA and the RMS on 17 July 2019. On the basis of the comments received, the applicant's response to the comments and the RMS's evaluation thereof, it was concluded that additional information should be requested from the applicant, and that EFSA should conduct an expert consultation in the areas of mammalian toxicology, environmental fate and behaviour and ecotoxicology, which took place in January 2022.

In addition, in June 2022, follow‐up meetings of experts from EFSA and Member States took place to further discuss elements related to mammalian toxicology and ecotoxicology.

Although the peer review process is not fully completed, with the assessment of the endocrine disruption properties according to point 3.8.2 of Annex II to Regulation (EC) No 1107/2009 remaining pending, all other aspects of the risk assessment are considered finalised. Likewise, the assessment concerning environmental fate and behaviour and ecotoxicology has been completed following the expert discussions in those areas. Subsequently, during the drafting of the EFSA Conclusion, EFSA informed the Commission that critical areas of concern have been identified for dimoxystrobin in those areas.

In this context, on 12 August 2022, prior to completion of the peer review process, EFSA was requested by the European Commission to provide a statement containing the available outcomes of the assessment related to environmental fate and behaviour and ecotoxicology. Given the critical concerns identified, a request in accordance with Commission Implementing Regulation (EU) No 2018/1659, to be able to conclude whether the approval criteria for endocrine disruption in line with the scientific criteria for the determination of endocrine‐disrupting properties, as laid down in Commission Regulation (EU) 2018/605 4 , are met, seems also not justified.

Based on that mandate, EFSA prepared a draft statement in September 2022 summarising the conclusions of the assessment of environmental fate and behaviour and ecotoxicology as finalised following the expert discussions held in January and June 2022 in the context of the peer review of the renewal of the approval of the active substance and the representative formulation, evaluated on the basis of the representative uses of dimoxystrobin as a fungicide on oilseed rape and sunflower, as proposed by the applicant.

The draft statement was circulated to all Member States for commenting via a written procedure. A list of the relevant end points for the active substance and the formulation is provided in Appendix B. In addition, the considerations as regards some of the cut‐off criteria for dimoxystrobin according to Annex II of Regulation (EC) No 1107/2009 are summarised in Appendix A.

A key supporting document to this statement is the peer review report (EFSA, 2022), which is a compilation of the documentation developed to evaluate and address all issues raised in the course of the peer review of the renewal of the active substance dimoxystrobin, from the initial commenting phase to the preparation of this statement. For reasons of completeness and transparency, the peer review report comprises all background documents, which were developed and finalised during the ongoing renewal process up to the production of the present statement and relate to all sections of the risk assessment, as follows:

  • the comments received on the RAR;

  • the reporting tables (22 July 2019);

  • the evaluation tables (September 2022);

  • the reports of the scientific consultation with Member State experts (where relevant);

  • the comments received on the assessment of the additional information (where relevant);

  • the comments received on the draft EFSA statement.

Given the importance of the RAR, including its revisions prepared up to the revision required following the expert consultations (Hungary, 2022), and the peer review report, both documents are considered as background documents to this statement and thus are made publicly available.

It is recommended that this statement and its background documents would not be accepted to support any registration outside the EU for which the applicant has not demonstrated that it has regulatory access to the information on which this statement is based.

1.1. Background and terms of reference as provided by the requestor

EFSA was mandated by the European Commission on 12 August 2022 to provide a statement containing the available outcomes of the assessment related to environmental fate and behaviour and ecotoxicology drawn in the context of the pesticides peer review for the renewal of approval of the active substance dimoxystrobin conducted in accordance with Commission Implementing Regulation (EU) No 844/2012. Given the critical concerns identified during the peer review, a request for additional information in accordance with Article 13(3a) of Regulation (EU) No 844/2012, to obtain information on endocrine disrupting properties, seems also not justified.

Although the peer review process is not yet fully completed, with the assessment of the endocrine disruption properties according to point 3.8.2 of Annex II to Regulation (EC) No 1107/2009 remaining pending, the assessment concerning environmental fate and behaviour and ecotoxicology has been finalised following the expert discussions held in January and June 2022 in those areas. During the drafting of the EFSA Conclusion the Commission was informed by EFSA that critical areas of concern have been identified for dimoxystrobin in those areas. The approval of dimoxystrobin expires on 31 January 2023 following several extensions in accordance with Article 17 of Regulation (EC) No 1107/2009. A further extension should be avoided if it is already clear that the approval criteria laid down in Regulation (EC) No 1107/2009 are not satisfied.

EFSA was requested to complete this mandate by 30 September 2022.

The active substance and the formulated product

Dimoxystrobin is an ISO common name for (2 E)‐2‐{2‐[(2,5‐dimethylphenoxy)methyl]phenyl}‐2‐(methoxyimino)‐N‐methylacetamide (IUPAC).

The representative formulated product for the evaluation was ‘BAS 540 01F’, a suspension concentrate (SC) containing 200 g/L dimoxystrobin and 200 g/L boscalid.

The representative uses evaluated were hydraulic foliar spray application on oilseed rape and sunflower as a fungicide against a broad range of pathogens. Full details of the good agricultural practices (GAPs) can be found in the list of end points in Appendix B.

Data were submitted to conclude that the uses of dimoxystrobin according to the representative uses proposed at EU level result in a sufficient fungicidal efficacy against the target pathogens, following the guidance document SANCO/2012/11251‐rev. 4 (European Commission, 2014b).

2. Assessment

2.1. Mammalian toxicity in relation to groundwater metabolites

The toxicological profile of the active substance dimoxystrobin and its metabolites was discussed at the Pesticides Peer Review Experts' Teleconference 70 in January 2022 and at the Pesticides Peer Review Experts' Teleconference 78 in June 2022. 5 The assessment of groundwater metabolites for their relevance was based on the following guidance document: European Commission, 2003.

Dimoxystrobin has harmonised classification according to Regulation (EC) No 1272/2008 6 as Carc. Cat. 2, H351 (‘Suspected of causing cancer’) and Repr. Cat. 2, H361d (‘Suspected of damaging the unborn child’). Metabolites 505M08 and 505M09 are unlikely to be genotoxic. Available data demonstrate that metabolites 505M08 and 505M09 do not share the carcinogenic properties of the parent compound; however, this is not the case for the reproductive toxicity properties of the parent. Consequently, they are considered as toxicologically relevant groundwater metabolites (see also Section 2.2). Metabolite 505M01 is considered unlikely to be mutagenic and clastogenic; however, aneugenicity has not been investigated (outstanding data gap). Data are missing to demonstrate that the metabolite 505M01 does not share the carcinogenicity and reproductive toxicity properties of the parent. Consequently, metabolite 505M01 has to be considered as toxicologically relevant groundwater metabolite (see also Section 2.2).

2.2. Environmental fate and behaviour

Dimoxystrobin was discussed at the Pesticides Peer Review Experts' Teleconference 71 in January 2022.

Dimoxystrobin test substance used in fate and behaviour studies included low amounts of Z‐isomer; however, the Z‐isomer remained at low levels in all environmental compartments. The sum of both isomers (E and Z) was considered for the environmental exposure assessment.

The rates of dissipation and degradation in the environmental matrices investigated were estimated using FOCUS (2006) kinetics guidance. In soil laboratory incubations under aerobic conditions in the dark, dimoxystrobin exhibited high persistence, forming the major (> 10% applied radioactivity (AR)) metabolite 505M09 (max. 13% AR, moderate to high persistence in soil) and metabolite 505M08 (> 10% of the initially measured dimoxystrobin in 0–10 cm soil layer in field studies, moderate to high persistence in soil). Mineralisation to carbon dioxide accounted for 15% AR after 119 days for the benzyl ring 14C radiolabel and for 25% AR after 122 days for the phenyl 14C radiolabel. The formation of unextractable residues accounted for 24% AR and 25% AR after 119 and 122 days for the benzyl and the phenyl 14C radiolabels, respectively. In anaerobic soil incubations, dimoxystrobin was essentially stable. In laboratory soil photolysis studies, dimoxystrobin degraded more rapidly than in the dark control forming the major metabolite 505M01 (max. 11% AR), which exhibited low to moderate persistence under aerobic dark conditions. Dimoxystrobin exhibited medium to low mobility in soil. Metabolites 505M08 and 505M09 exhibited very high to high mobility, and 505M01 exhibited very high soil mobility. It was concluded that the adsorption of dimoxystrobin and metabolite 505M01 was not pH dependent, while the adsorption of metabolites 505M08 and 505M09 was pH dependent, with adsorption decreasing in alkaline soils. In satisfactory field dissipation studies carried out at four sites in Germany, three in Spain, one in Sweden, one in Italy, one in France and one in the UK, dimoxystrobin exhibited medium to high persistence in soil. Sample analyses were carried out for dimoxystrobin, 505M01, 505M08 and 505M09. These three metabolites were only determined sporadically above the limit of quantification precluding the derivation of formation and decline kinetic endpoints. Field study DegT50 values for parent dimoxystrobin were derived following normalisation to FOCUS reference conditions (20°C and pF2 soil moisture) following the EFSA (2014) DegT50 guidance. The field data endpoints were not combined with laboratory values to derive modelling endpoints as following the DegT50 guidance the laboratory and field values were considered to represent different populations.

In a lysimeter study of 2‐year duration, the mean annual concentration of dimoxystrobin was < 0.1 μg/L. Metabolites 505M08 and 505M09 were found to reach a maximum annual average concentration of 2.35 μg/L and 2.0 μg/L, respectively. No other known metabolites were detected in any leachate sample.

In laboratory incubations in dark aerobic natural sediment water systems, dimoxystrobin exhibited high to very high persistence, forming the major metabolite 505M96 (max. 10% AR in water exhibiting moderate persistence). The unextractable sediment fraction (not extracted by acetonitrile/water) accounted for 6–11% AR at study end (100 days) for the phenyl and benzyl ring 14C radiolabel. Mineralisation of this radiolabel accounted for only 0.8–2.1% AR at the end of the study. The rate of decline of dimoxystrobin in a laboratory sterile aqueous photolysis experiment was faster (low persistence) relative to that which occurred in the aerobic sediment water incubations. No chromatographically resolved component (excluding dimoxystrobin) accounted for > 8% AR.

The necessary surface water and sediment exposure assessments (predicted environmental concentrations (PEC) calculations) were carried out for the metabolites 505M08, 505M09, 505M01 and 505M96, using the FOCUS (FOCUS, 2001) step 1 and step 2 approach (version 3.2 of the Steps 1–2 in FOCUS calculator). For the active substance dimoxystrobin, appropriate step 3 (FOCUS, 2001) and step 4 calculations were available. 7 The step 4 calculations appropriately followed the FOCUS (FOCUS, 2007) guidance, with no‐spray drift buffer zones of up to 20 m being implemented for the drainage scenarios (representing a 57–92.5% spray drift reduction), and combined no‐spray buffer zones with vegetative buffer strips of up to 20 m (reducing solute flux in run‐off by 80% and erosion run‐off of mass adsorbed to soil by 95%) being implemented for the run‐off scenarios. The SWAN tool (version 5.0.1) was appropriately used to implement these mitigation measures in the simulations. However, risk managers and others may wish to note that whilst run‐off mitigation is included in the step 4 calculations available, the FOCUS (FOCUS, 2007) report acknowledges that for substances with KFoc < 2,000 mL/g (i.e. dimoxystrobin), the general applicability and effectiveness of run‐off mitigation measures had been less clearly demonstrated in the available scientific literature, than for more strongly adsorbed compounds.

The necessary groundwater exposure assessments were appropriately carried out using FOCUS (European Commission, 2014a) scenarios and the models PEARL 4.4.4, PELMO 5.5.3 and MACRO 5.5.4 7 for dimoxystrobin and its metabolites. The potential for groundwater exposure from the representative uses by dimoxystrobin above the parametric drinking water limit of 0.1 μg/L was concluded to be low in geoclimatic situations that are represented by all six FOCUS groundwater scenarios.

For the representative use on oilseed rape (early and late triennial applications), the 80th percentile annual average recharge concentrations leaving the 1 m soil layer were estimated to be > 0.1 μg/L at all of the six scenarios for metabolites 505M08 and 505M09 in both acidic and alkaline soils, and in one of six scenarios for metabolite 505M01.

For the representative use on sunflowers (triennial application), the 80th percentile annual average recharge concentrations leaving the 1 m soil layer were estimated to be > 0.1 μg/L at both of the FOCUS sunflower scenarios for metabolite 505M08 in both acidic and alkaline soils and for metabolite 505M09 in alkaline soils, and in one of these two scenarios for metabolite 505M09 in acidic soils, while concentrations leaving the 1 m soil layer were estimated to be < 0.1 μg/L at both of the scenarios for metabolite 505M01.

It should be noted that though concentrations in groundwater were > 0.75 μg/L for metabolites 505M08 and 505M09 as they are concluded as relevant at Step 3 of the applicable guidance (see Sections 2.1 and 2.5), the only concentration that needed to be assessed against was 0.1 μg/L.

A critical area of concern is identified (see Section 3.1.2) as relevant groundwater metabolites (see Sections 2.1 and 2.5) have been indicated to be above the parametric drinking water limit of 0.1 μg/L in annual average recharge concentrations leaving the top 1 m soil layers in geoclimatic conditions represented by all the pertinent FOCUS groundwater scenarios and in a relevant lysimeter, in the context of all the representative uses assessed and the whole range of soil pH conditions.

The applicant provided appropriate information to address the effect of water treatment processes on the nature of the residues that might be present in surface water and groundwater, when surface water or groundwater are abstracted for drinking water, though it should be noted that for groundwater metabolites 505M01, 505M08 and 505M09, concentrations will legally need to be below 0.1 μg/L in groundwater.

The PEC in soil, surface water, sediment and groundwater covering the representative uses assessed can be found in Appendix B of this statement. A key to the wording used to describe the persistence and mobility of the compounds assessed can be found in Appendix C of this statement.

2.3. Ecotoxicology

The risk assessment was based on the following documents: European Commission (2002), SETAC (2001), EFSA (2009, 2013) and EFSA PPR Panel (2013).

The representative formulation, ‘BAS 540 01 F’, contains a second active substance (i.e. boscalid) in the same proportion. In some cases, different formulations than the representative one were used in the ecotoxicity tests (‘BAS 540 00F’; ‘BAS 505 01F’, a solo‐formulation; and ‘BAS 507 00F’, the old representative formulation, which contains epoxiconazole as second active substance in lower proportion). Based on all the available information, bridging between the formulations ‘BAS 540 01 F’ and ‘BAS 540 00 F’ is supported and both formulations can be considered comparable.

Several aspects pertaining to the risk assessment of dimoxystrobin were discussed at the Pesticide Peer Review Experts' Teleconference 72 (January 2022) and at the Pesticides Peer Review Experts' Teleconference 79 in June 2022.

Suitable acute and long‐term ecotoxicity studies were available with dimoxystrobin with birds 8 and mammals. 9 Acute studies with the representative formulation were also available for both groups. A low acute and long‐term risk to birds and mammals was identified for all representative uses.

An assessment of the major plant metabolites of dimoxystrobin (i.e. 505M01, 505M08, 505M09, 505M93, 505M95, 505M96), to which birds and wild mammals can be exposed, was available in the RAR and the risk was considered as low. In addition, the risk to birds and mammals resulting from the exposure to contaminated water and the risk due to secondary poisoning were also concluded as low for all representative uses.

Acute toxicity data with the active substance were available for fish (three species) and aquatic invertebrates (on the standard species Daphnia magna, on Asellus aquaticus, and with the marine species Americamysis bahia and Crassostrea virginica). The aquatic invertebrate endpoints for A. aquaticus and on A. bahia were discussed at the experts' meeting. 10

Chronic toxicity data with the active substance were available for fish, aquatic invertebrates and algae. No reliable data were available for macrophytes.

Acute toxicity data with fish and aquatic invertebrates as well as chronic data for algae were available with the representative formulation.

In addition, acute toxicity data with other formulations (‘BAS 505 01 F’ and ‘BAS 507 00 F’) were also available with additional fish species. The reliability of several acute fish studies was discussed during the experts' meeting. 11

The potential use of the fish acute toxicity data with formulations including a second active substance in a refinement at Tier 2 was also discussed at the experts' meeting. 12 It was agreed that data from formulation with another active substance should not be used in Tier 2 assessment since the presence of another active substance would add uncertainty to the calculation. Therefore, only data on the active substance and the solo‐formulation were considered at Tier 2, using the geomean approach; the species sensitivity distribution (SSD) approach was not considered acceptable for the refined risk assessment, since it includes data from formulation with two active substances.

Endpoints for the two chronic early‐life stage (ELS) fish studies and the two chronic fish modified exposure studies were discussed at the experts' meeting. 13 It was agreed that the endpoint of 8 μg/L from a standard ELS study on fathead minnow (revised to cover potential effect on growth) should be used in the risk assessment. Toxicokinetic–Toxicodynamic (TKTD) modelling, using the General Unified Threshold model of Survival (GUTS), was submitted for refining the chronic risk assessment for fish, and was discussed in the follow‐up experts' meeting. 14 The TKTD model was comprehensively reported and relied on a large experimental data set. However, the calibration and the interpretation of the validation of the model presented some deficiencies which decrease the overall reliability of the model application. In addition, GUTS model addresses lethal effects whereas the Tier 1 risk assessment was driven by sublethal effects; the calibration/validation of the model was carried out for rainbow trout whereas the sublethal effects were observed on the fathead minnow, and interspecies extrapolation is not recommended in the EFSA PPR Panel (2018). Therefore, the experts concluded that this modelling could not be used for refining the chronic fish risk assessment for dimoxystrobin.

For further refinement for aquatic invertebrates, a mesocosm study was also available with the solo formulation. The proposed endpoint from the mesocosm study was also discussed during the experts' meetings. 15 The experts agreed that an overall endpoint could not be derived for aquatic organisms due to several shortcomings (e.g. few species), especially vulnerable ones, with sufficient abundance; lack of pre‐exposure sampling for some taxa which makes it difficult to assess the effect; an effect class 3A was observed at the lowest concentration which makes it impossible to derive an ETO‐RAC (ecological threshold option – Regulatory Acceptable Concentration). Only a specific provisional ecological recovery option (ERO) – RAC could be derived for Daphnia, and the experts agreed not to use this endpoint in the risk assessment since it has not been demonstrated that the exposure in the mesocosm covers the predicted exposure profiles of the representative uses and that this endpoint might not be protective enough for molluscs (driving the Tier 1 risk assessment), crustaceans with long reproductive cycle and the most sensitive phytoplankton taxa.

Regarding sediment‐dwelling organisms, toxicity data were available with the active substance.

Based on the available Tier 1 data, a high acute risk for fish and aquatic invertebrates was identified at FOCUS Step 3 for all scenarios for the two representative uses.

Considering Tier 2 refinement (geomean), a high acute risk to fish was identified for all scenarios and representative uses using FOCUS Step 3 PECsw, except for scenario D5 on sunflower. At FOCUSsw Step 4, a high acute risk to fish remained for 2/6 scenarios (D2 and D4) for use on oilseed rape. Low acute risk was concluded for the remaining scenarios for the use on oilseed rape when considering risk mitigation measures (RMM) up to 20 m no‐spray buffer zone in combination with 20 m vegetated filter strip. For the use on sunflower, low acute risk to fish was concluded when considering RMM up to 20 m no‐spray buffer zone in combination with a 20 m vegetated filter strip.

An overview of the outcome of the risk assessment for aquatic organisms is presented in Table 1 below.

HR: High risk remaining with the RMM; LR: Low risk concluded (FOCUS step 3).

LR step 4 10 m + 10 m: Low risk concluded at FOCUS step 4 with RMM of 10 m no‐spray buffer zone in combination with a 10 m vegetated filter strip.

LR step 4 20 m + 20 m: Low risk concluded at FOCUS step 4 with RMM 20 m no‐spray buffer zone in combination with a 20 m vegetated filter strip.

By using Tier 1 data, high chronic risk for fish was identified at FOCUS Step 3 for 4/6 scenarios for the representative use on oilseed rape and 3/4 scenarios for use on sunflower. At FOCUSsw Step 4, for the use in oilseed rape, a high chronic risk to fish remains with a 20‐m buffer zone combined with a 20‐m vegetated filter strip for 2/6 scenarios; low chronic risk to fish was concluded when considering a 10‐m no‐spray buffer zone in combination with a 10‐m vegetated filter strip for the two remaining scenarios. For the representative use on sunflower, low chronic risk was concluded when considering a 10‐m no‐spray buffer zone in combination with a 10‐m vegetated filter strip for all remaining scenarios.

For acute risk to aquatic invertebrates, based on the most sensitive species (C. Virginica, acute endpoint based on shell deposition), high risk was concluded for all relevant scenarios and uses (except for one scenario (D3) for the use on oilseed rape) at FOCUSsw Step 4 when considering a 20‐m no‐spray buffer zone in combination with a 20‐m vegetated filter strip (critical area of concern, see Section 3.1.2).

High chronic risk to aquatic invertebrates was identified at FOCUS Step 3 for 3/6 scenarios for the use on oilseed rape. By using FOCUSsw Step 4 exposure estimations, a high chronic risk remains for one scenario; low chronic risk to aquatic invertebrates was concluded when considering a 10‐m no‐spray buffer zone in combination with a 10‐m vegetated filter strip for two scenarios. For the use on sunflower, the chronic risk was high at FOCUS step 3 for 1/4 scenarios, for which a low risk was identified at FOCUSsw Step 4, with a 10‐m no‐spray buffer zone in combination with a 10‐m vegetated filter strip.

In addition, high chronic risk to sediment‐dwelling organisms was concluded at FOCUSsw Step 3 for all scenarios for both representative uses. Using the FOCUSsw Step 4 calculations that considered a 20‐m no‐spray buffer zone in combination with a 20‐m vegetated filter strip, high chronic risk to sediment‐dwelling organisms was identified for 3/6 scenarios for the use on oilseed rape. For the use on sunflower, low risk was concluded at FOCUSsw Step 4 for all scenarios when considering RMM up to 20 m no‐spray buffer zone combined with 20 m vegetated filter strip.

By using FOCUSsw Step 3 calculations, 4/6 and 3/4 scenarios showed a high risk to algae for the uses in oilseed rape and sunflower, respectively. At FOCUSsw Step 4, for the use on oilseed rape, the high risk remained for two scenarios (D2 and D4) even after considering a 20‐m no‐spray buffer zone in combination with a 20‐m vegetated filter strip, whereas a low risk was identified for the remaining scenarios when considering a 10‐m no‐spray buffer zone in combination with a 10‐m vegetated filter strip. For the use on sunflower, a low risk to algae could be concluded when considering a 10‐m no‐spray buffer zone in combination with a 10‐m vegetated filter strip.

To conclude on aquatic organisms, 1/6 scenarios show a low risk applying RMM of 20 m no‐spray buffer zone in combination with 20 m vegetated filter strip for the use on oilseed rape, whereas a high risk is identified for the remaining five scenarios; for the use on sunflower, a high risk is identified for all scenarios even considering RMM.

Several pertinent metabolites of dimoxystrobin have been identified in surface water (501 M01, 505M08, 505M09, 505M096). These pertinent aquatic metabolites were tested acutely for fish, invertebrates and algae. Low acute risk was concluded for all the pertinent aquatic metabolites by using FOCUS Step 1 PECsw for fish, aquatic invertebrates and algae for all uses. The metabolites 505M08, 505M09, 505M01, 505M96 were also identified as relevant in the sediment phase. However, no risk assessment for sediment dwellers was submitted (data gap, see Section 3.2).

Oral acute toxicity data on honeybees were available for dimoxystrobin and two formulated products (i.e. ‘BAS 540 01 F’ and ‘BAS 540 00 F’ 16 ). Acute contact toxicity data were available for the same formulations but not for the active substance (data gap, see Section 3.2). Furthermore, chronic studies for larvae and adults were available. The chronic toxicity study was conducted with the active substance whilst the 8‐day larval toxicity study was conducted with the representative formulation. Since this latest study does not cover the main developmental stages of honeybee larvae in line with the current recommendations, a data gap for a proper study with honeybee larvae was identified (i.e. a test with repeated dosing and longer test duration according to OECD Guidance No 239 is preferable; see also below paragraph for further information). 17 No information was available on bumblebees and solitary bees.

An acute risk assessment following the SANCO Guidance on Terrestrial ecotoxicology (European Commission, 2002) was available. Low acute risk to honeybees from oral and contact 18 exposure was concluded for both representative uses. Following the Tier 1 risk assessment according to the EFSA bee guidance (EFSA, 2013), the same conclusion could be reached for the acute scenario as assessed with the SANCO Guidance. Likewise, low chronic risk to adult honeybees could also be concluded for all representative uses, and the acute and chronic risk to adult bees from exposure to contaminated water was considered low as well.

A suitable assessment for sublethal effects (e.g. hypopharyngeal glands (HPGs)) was not available (data gap, see Section 3.2). An assessment to address the potential effects of plant metabolites occurring in pollen and nectar as a result of the representative uses was not available (data gap, see Section 3.2). An assessment of accumulative effects on bees was not available.

In addition to the Tier 1 ecotoxicity data for honeybees, a number of higher tier studies were also available. The available tunnel study considered ecotoxicological parameters related to the honeybee risk assessment (i.e. brood developmental observations) whilst the other two studies, residue studies under semi‐field and field conditions, 19 aimed at characterising the residue situation in pollen and nectar for oilseed rape and sunflowers. Those studies were discussed at the experts' meeting. 20

The information from the residue studies showed several deficiencies (i.e. the sampling method was not in line with the recommendations of the EFSA bee guidance (EFSA, 2013), the residue trials were not independent from each other, there were adverse environmental conditions that could have affected the residue decline etc.); therefore, it was concluded that the information provided could not be used to refine exposure parameters in the risk assessment equations.

In the tunnel study, high variability on the brood termination rate was observed. In addition, due to several shortcomings in terms of experimental set‐up and conditions, the study was considered unsuitable to fully address the risk to honeybee larvae. As a consequence of the data gap identified for Tier 1 data for honeybee larvae as indicated previously and the unsuitability of a refinement based on the available tunnel study, the risk assessment for honeybee larvae is considered as an issue that could not be finalised (see Section 3.1.1).

Standard and extended laboratory toxicity tests with the formulation ‘BAS 540 00 F’ were available for non‐target arthropods other than bees. By using the available data, low in‐ and off‐field risk could be concluded for all representative uses.

Based on the available laboratory data with dimoxystrobin, high chronic risk was identified for earthworms for all representative uses at Tier 1. Three field studies were available to refine the risk. The studies were discussed at the experts' meeting. 21 Two were considered only as supportive information due to several shortcomings identified (e.g. uncertain exposure, limited information in terms of pre‐application sampling and pesticide history, poor performance of the toxic reference), whilst the study conducted in line with the GAPs under assessment was considered reliable and relevant to refine the risk. Considering the information from all the studies, it was possible to conclude low risk for earthworms for both representative uses.

For other soil macro‐ and meso‐fauna (i.e. Folsomia candida and Hypoaspis aculeifer), low chronic risk was concluded for all representative uses at Tier1.

Low risk to soil organisms from the exposure to the soil metabolite 505M09 was concluded for all representative uses. For the other relevant soil metabolites (i.e. 501M01, 505M08), toxicity data were not available for all non‐target soil organism taxa–metabolite combination. However, considering that metabolite 505M09 represents the worst‐case metabolite in soil in terms of formed fraction and degradation time, low chronic risk to soil organisms could be concluded for all the other relevant soil metabolites for the representative uses under assessment.

Suitable ecotoxicity tests were available to conclude a low risk to soil microorganisms for the active substance as well as for all the relevant soil metabolites for all representative uses.

A low chronic risk to non‐target terrestrial plants and organisms involved in biological methods for sewage treatment was concluded for all the representative uses.

3. Conclusions

3.1. Concerns and related data gaps for the representative uses evaluated

3.1.1. Issues that could not be finalised

An issue is listed as ‘could not be finalised’ if there is not enough information available to perform an assessment, even at the lowest tier level, for one or more of the representative uses in line with the uniform principles in accordance with Article 29(6) of Regulation (EC) No 1107/2009 and as set out in Commission Regulation (EU) No 546/2011 22 and if the issue is of such importance that it could, when finalised, become a concern (which would also be listed as a critical area of concern if it is of relevance to all representative uses).

An issue is also listed as ‘could not be finalised’ if the available information is considered insufficient to conclude on whether the active substance can be expected to meet the approval criteria provided for in Article 4 of Regulation (EC) No 1107/2009.

The following issues or assessments that could not be finalised have been identified, together with the reasons including the associated data gaps where relevant, which are reported directly under the specific issue to which they are related:

  • 1

    The risk assessment to honeybee larvae could not be finalised due to the lack of reliable information (applicable for all the representative uses, see Section 2.3).

  1. A chronic toxicity study with honeybee larvae in line with OECD Guidance No 239 is required (applicable for all the representative uses, see Section 2.3).

3.1.2. Critical areas of concern

An issue is listed as a critical area of concern if there is enough information available to perform an assessment for the representative uses in line with the uniform principles in accordance with Article 29(6) of Regulation (EC) No 1107/2009 and as set out in Commission Regulation (EU) No 546/2011, and if this assessment does not permit the conclusion that, for at least one of the representative uses, it may be expected that a plant protection product containing the active substance will not have any harmful effect on human or animal health or on groundwater, or any unacceptable influence on the environment.

An issue is also listed as a critical area of concern if the assessment at a higher tier level could not be finalised due to lack of information, and if the assessment performed at the lower tier level does not permit the conclusion that, for at least one of the representative uses, it may be expected that a plant protection product containing the active substance will not have any harmful effect on human or animal health or on groundwater, or any unacceptable influence on the environment.

An issue is also listed as a critical area of concern if, in the light of current scientific and technical knowledge using guidance documents available at the time of application, the active substance is not expected to meet the approval criteria provided for in Article 4 of Regulation (EC) No 1107/2009.

The following critical areas of concern are identified, together with any associated data gaps, where relevant, which are reported directly under the specific critical area of concern to which they are related:

  • 2

    High acute risk to aquatic invertebrates for 5/6 scenarios for the use on winter oilseed rape and all scenarios for the use on sunflower (see Section 2.3) when also considering the implementation of the assessed mitigation measures that reduced exposure (20 m no‐spray buffer zone +20 m vegetated filter strip). 23

  • 3

    High potential for groundwater contamination by groundwater relevant metabolites in geoclimatic conditions represented by all the relevant FOCUS groundwater scenarios for all the representative uses assessed (see Sections 2.1, 2.2 and 2.5).

(If a particular condition proposed to be taken into account to manage an identified risk, as listed in Section 2.4, has been evaluated as being effective, then ‘risk identified’ is not indicated in Table 6).

3.2. List of other outstanding issues

Remaining data gaps not leading to critical areas of concern or issues not finalised but considered necessary to comply with the data requirements, and which are relevant for some or all of the representative uses assessed at EU level. Although not critical, these data gaps may lead to uncertainties in the assessment and are considered relevant.

These data gaps refer only to the representative uses assessed and related to the environmental assessments:

  • The aneugenicity potential for metabolite 505M01 was not investigated (relevant for all representative uses, see Section 2.1).

  • No aquatic risk assessment for sediment dwellers was provided for the metabolites 505M08, 505M09, 505M01 and 505M96 (relevant for all representative uses, see Section 2.3).

  • Acute contact toxicity data with dimoxystrobin for bees were not available (relevant for all representative uses, see Section 2.3).

  • Further data were not available to address the risk to honeybees from sublethal effects (e.g. effects on HPG) and via exposure to metabolites formed in pollen and nectar (relevant for all representative uses, see Section 2.3).

Further testing on aquatic organisms

Potential endocrine‐disrupting properties (Annex Part A, point 8.2.3)

The available information in the data set provided very limited information for the EAS‐modalities since ED‐mediated parameters were not investigated in those studies but only sensitive parameters. Further information is required to finalise the ED assessment. For the T‐modality only preliminary results of the XETA (OECD TG 248) were available. The results of this test were negative for thyroid activity. Therefore, dimoxystrobin does not meet the ED criteria for the T‐modality for non‐target organisms since the T‐mediated endocrine activity was sufficiently investigated and was negative. For details, please refer to the ED assessment in Vol 1.

(1)

(nom) nominal concentration; (mm) mean measured concentration; n.d.: not determined

(2)

Study was conducted with the formulated product BAS 540 01 F (suspension concentrate formulation containing 200 g dimoxystrobin/L and 200 g boscalid/L, nominally; new representative formulated product).

(3)

Study was conducted with the formulation BAS 540 00 F (a minor change formulation of BAS 540 01 F, which differs only in the preservative used).

(4)

Study was conducted with the formulated product BAS 507 00 F (suspension concentrate formulation containing 133 g dimoxystrobin/L and 50 g epoxiconazole/L, nominally; former representative formulated product during Annex I inclusion process for dimoxystrobin). Epoxiconazole does not have significant influence on toxicity (dimoxystrobin being the single driver with > 99.5% TU) within the formulation BAS 507 00 F.

(5)

Study was conducted with the solo‐formulation BAS 505 01 F (containing 167 g dimoxystrobin/L, nominally).

(6)

Interpolated value (geometric mean) with corresponding LC0 (>) and LC100 (<)

(7)

Study is not considered fully reliable due to some deviations with respect to the recommendations of the test guideline.

(8)

Study is not considered fully reliable because it cannot be excluded that the sensitive life stages were not exposed adequately.

(9)

This endpoint is not considered protective of species with a longer reproductive cycle.

A semifield tunnel study conducted with BAS 540 01 F and two residue field studies were available. For further information, please see RAR Vol 3 CP 9, Sections B.9.5.1.6 and B.9.5.1.7.

Risk assessment for dimoxystrobin includes application in winter oilseed rape (2 × 0.5 L BAS 540 01 F/ha, with an application interval of 28 d) and sunflower (1 × 0.5 L BAS 540 01 F/ha)

For the calculation of the HQ values, the maximum single application rate of 500 mL/ha was multiplied by the product density of 1.118 g/cm3. For acute contact, the endpoint obtained in the study with the product was considered for risk assessment purposes as it was expressed in terms of a.s. equivalent.

The following risk assessment was carried out according to EFSA Bee GD (2013).

Ecotoxicity endpoints for bees obtained from both formulations are similar and are in the same range. The formulations are comparable based on existing information.

17

A further consideration to the risk to honey bee larvae is given below taking into account the available tunnel study.

18

The endpoint obtained from the product study but expressed as a.s. equivalent was used for risk assessment purposes.

19

One of the residue studies was conducted under semi‐field conditions, while the other study was a field study.

With these risk mitigation measures, the exposure reduction is just below the limit of 95% (92.5%) for spray drift that is recommended by the FOCUS Landscape and mitigation guidance (FOCUS, 2007). Whilst theoretically there is a small margin, it is unlikely that with the absolute 95% drift reduction (i.e. with a 30‐m no‐spray buffer zone resulting in 94.94% drift reduction; also using 50% drift reducing nozzle +10 m buffer zone is essentially the same) any additional scenario would pass, nevertheless the risk assessment to absolutely confirm the situation is not available from the peer review. Nonetheless, it is unlikely that the critical area of concern would change.

For laboratory soil incubations normalisation was also to field capacity soil moisture (pF2/10kPa). For laboratory sediment water system incubations, the whole system DT values were used.
