New EU use conditions for citronella oil
Certain risk mitigation measures have been added to the EU approval of the herbicide, citronella oil. When approving products, EU member states must consider measures to protect operators, workers, bystanders, residents, ground water and non-target organisms. Existing product authorisations have to be amended, if necessary, by December 5th. A further condition requires the notifier, UK company Barrier Biotech, to submit confirmatory data by April 30th 2016 on: the technical specification; a comparison of natural background exposure of citronella oil, methyl eugenol and methyl isoeugenol with exposure from agrochemical use; and the ground water exposure for metabolites. The amended use conditions were cleared in April following an assessment by the European Food Safety Authority (EFSA – Agrow No 687, p 18). Citronella oil was originally approved in 2009 under a scheme that allowed faster authorisation of “low-risk” active ingredientis before the EFSA had completed its peer review. Barrier Biotech sells the ai as Barrier H, a spot treatment for the poisonous grassland weed, ragwort (Senecio jacobaea).
