Mefentrifluconazole is an approved active substance in Great Britain (GB). An application was received by the Health and Safety Executive (HSE) requesting new Maximum Residue Levels (MRLs) for mefentrifluconazole in/on blueberries, currants (black, red and white) and mulberries (black and white). Following assessment, new MRLs have been introduced to accommodate new extensions of authorisations for minor use of plant protection products in Great Britain for: Blueberries from 0.01* mg/kg to 2 mg/kg, Mulberries (black and white) from 0.01 mg/kg to 2 mg/kg, Currants (black, red and white) from 2 mg/kg (temporary MRL) to 2 mg/kg. The Evaluation Report/Reasoned Opinion supporting the new MRLs is available at the following link: The evaluation of new MRLs for mefentrifluconazole in or on various commodities. The assessment/ reasoned opinion has concluded that the residue levels arising in food from the notified uses result in consumer exposures below the toxicological reference values.
