The European Commission have published a draft Commission Implementing Regulation renewing the approval of the active substance metalaxyl-M, and restricting the use of seeds treated with plant protection products containing it. This proposal is in accordance with Regulation (EC) No 1107/2009 of the European Parliament and of the Council concerning the placing of plant protection products on the market, and amending the Annex to Commission Implementing Regulation (EU) No 540/2011 (5 pages plus Annexes 4 pages, in English). This draft Commission Implementing Regulation provides that the approval of the active substance metalaxyl-M is renewed in accordance with Regulation (EC) No 1107/2009, subject to certain restrictions including to the use of seeds treated with product containing metalaxyl-M. Use as seed treatment is permitted, however, treated seeds shall only be sown in greenhouses. Other uses e.g. foliar spraying can still be authorised by EU Member States. Existing authorised plant protection products containing metalaxyl-M will be reviewed in accordance with the proposed restrictions. The renewal of approval is based on the first evaluation of the substance for use as a pesticide active substance in the EU under Regulation (EC) No 1107/2009. The substance was formerly approved under Directive 91/414/ EEC. This decision only concerns the placing on the market and use of metalaxyl-M and plant protection products containing it. The decision does not affect existing Maximum Reside Levels (MRLs).

Protection of human health or safety; protection of animal or plant life or health; protection of the environment. In order for an active substance to be approved in accordance with Regulation (EC) No 1107/2009 (concerning the placing of plant protection products on the market), it must be demonstrated that the substance is not harmful to human health, animal health or the environment. Criteria are listed in Article 4 of the Regulation (and also detailed in Annex II) which must be met to enable approval. During the evaluation and peer-review of metalaxyl-M, a number of concerns were identified. These are detailed in the conclusion of the European Food Safety Authority (EFSA). EFSA concluded that based on the information available, the genotoxic potential of one impurity (2-[(2,6-dimethyl-phenyl)-(2-methoxyacetyl)-amino]-propionic acid 1-methoxycarbonyl-ethyl ester) in the technical active substance as manufactured could not be ruled out. However, the evaluation showed that if the impurity is present below a certain level (0.18 g/kg) that a concern does not exist. Furthermore, two other impurities (2,6-dimethylphenylamine and 4-methoxy-5-methyl-5H-[1,2]oxathiole 2,2-dioxide) are considered toxicologically relevant. It is therefore necessary to establish maximum levels for those three impurities in the technical active substance as manufactured. EFSA also identified a high risk to birds and mammals from the use of metalaxyl-m as a seed treatment. In order to address this concern, seeds treated with metalaxyl-M shall only be sown in greenhouses. The risk from consumption of seedlings was considered acceptable for the two representative crops considered (sunflowers and spinach). For the use on spinach, residue data allow to conclude that seedlings can be planted in the field after 21 days. For other crops, such data are not available. EU Member States therefore need to pay particular attention to the period before seedlings can be planted in open fields. Existing authorisations will need to be amended or withdrawn following renewal of authorisation in accordance with Article 43 of Regulation (EC) No 1107/2009.
