2015-2015: EPA registration assessment

Building on previous and ongoing data initiatives, this consultancy project aimed to undertake an intensive literature review and critical evaluation of published data for a range of essential oils to support the regulatory evaluation and approval processes of various rodenticidal biopesticide products based on these oils. Biopesticides are pesticides that have been derived from natural materials such as animals, plants and bacteria. They are usually inherently less toxic than conventional synthetic chemical pesticides and often control pests by non-toxic mechanisms. For example, many essential oil based biopesticides have non-contact activity, such as repellents. Nevertheless, such substances must still be thoroughly investigated to ensure that they do not pose unreasonable risks to human health or the environment. The data collated for this project was that prescribed by the US Environmental Protection Agency (40CFR 158.2050 & 40CFR 150.2060) and covered basic physico-chemical properties of the oils as well as human toxicological and non-target toxicological data to Tier I only.
