RESUMEN
The conclusions of EFSA following the peer review of the initial risk assessments carried out by the competent authorities of the rapporteur Member State The Netherlands and co-rapporteur Member State Germany for the pesticide active substance dimethomorph and the assessment of applications for maximum residue levels (MRLs) are reported. The context of the peer review was that required by Commission Implementing Regulation (EU) No 844/2012, as amended by Commission Implementing Regulation (EU) No 2018/1659. The conclusions were reached on the basis of the evaluation of the representative uses of dimethomorph as a fungicide applied via foliar spraying on field strawberry and grapevine crops and permanent greenhouse lettuce crops; via drenching on field and permanent greenhouse strawberry crops and via dripping on permanent greenhouse strawberry crops. The peer review also provided considerations on whether exposure to humans and the environment from the representative uses of dimethomorph can be considered negligible, taking into account the European Commission's draft guidance on this topic. MRLs were assessed in potatoes, other root and tuber vegetables (except radishes), stem vegetables (except celery, leeks, globe artichokes, sugar beet, cereal forage and straw). The reliable end points, appropriate for use in regulatory risk assessment and the proposed MRLs, are presented. Missing information identified as being required by the regulatory framework is listed. The concerns are reported where identified.

RESUMEN
The conclusions of EFSA following the peer review of the initial risk assessments carried out by the competent authorities of the rapporteur Member State Italy and co-rapporteur Member State the United Kingdom for the pesticide active substance metiram are reported. The context of the peer review was that required by Commission Implementing Regulation (EU) No 844/2012, as amended by Commission Implementing Regulation (EU) No 2018/1659. The conclusions were reached on the basis of the evaluation of the representative uses of metiram as a fungicide on grapes (wine table) and potatoes (all being field uses). It was concluded that following the guidance on this topic, metiram has endocrine disrupting potential, which is a cut-off criterion for non-approval of an active substance. Considerations are also provided on whether exposure to humans and the environment from the representative use of metiram on potatoes can be considered negligible, taking into account information from the applicant and the European Commission's draft technical guidance on this topic. The information available indicated this exposure was not negligible. The reliable end points, appropriate for use in regulatory risk assessment are presented. Missing information identified as being required by the regulatory framework is listed. Concerns are reported where identified. An evaluation of data concerning the necessity of metiram as a fungicide to control a serious danger to plant health which cannot be contained by other available means, including non-chemical methods is also presented.

RESUMEN
The conclusions of the European Food Safety Authority (EFSA) following the peer review of the initial risk assessments carried out by the competent authorities of the rapporteur Member State, Lithuania, and co-rapporteur Member State, Latvia, for the pesticide active substance trinexapac and the assessment of applications for maximum residue levels (MRLs) are reported. The context of the peer review was that required by Commission Implementing Regulation (EU) No 844/2012. The conclusions were reached on the basis of the evaluation of the representative use of trinexapac as a plant growth regulator on barley (winter and spring) and wheat (winter). MRLs were assessed in rye. The conclusions were updated with regard to the endocrine-disrupting properties following a mandate received from the European Commission in January 2019.The reliable end points, appropriate for use in regulatory risk assessment and the proposed MRLs, are presented. The confirmatory data following the review of existing MRLs according to Article 12 of Regulation (EC) No 396/2005 were also assessed under this conclusion. Missing information identified as being required by the regulatory framework is listed. Concerns are reported where identified.
RESUMEN
The use of lipase D (Rhizopus delemar) immobilised on microporous polypropylene as a replacement for the standard pancreatic lipases used in the stereospecific sn-2 position analysis of triacylglycerols from edible oils and fats is studied. Excellent hydrolysis characteristics are obtained in hexane/methanol solvents at reaction temperatures up to 60 degrees C with hydrolysis times of only 10-20 min. The favourable conditions for the hydrolysis reaction allow fats with higher melting points to be analysed and facilitate coupling of the hydrolysis reaction to the later steps in the analytical protocol. The performance of the new method is compared to that of the standard method using pancreatic lipase. The novel procedure is faster, manual sample handling is reduced, while the results obtained with both methods are comparable. The influence of alkyl-chain length on hydrolysis rates seems to be negligible for the most common vegetable fatty acids. Acyl migration was found to be absent. The short-term repeatability of the method ranges from 10% for fatty acids present at levels close to the detection limits to less than 1% for the major fatty acids. The detection limit is approximately 0.05%. Although the application of the immobilised enzyme in fully automated sn-2 position analysis seems to be promising, the attempts to do this using a packed bed reactor were not successful due to a rapid loss of enzyme activity.
