One of the deliverables from the OECD Pesticide Dissipation Project is a GIS-based application to assess the similarity of ecoregions between Europe and North America. The objective of this tool is to find matching ecoregions which enable registrants to demonstrate that foreign test site conditions exist in either Europe or North America. This GIS application has the potential of being used in a variety of manners. In this presentation, we will explore how the tool and the underlying data can be used to find locations with conditions that match foreign test sites, how the tool compares with the current US EPA foreign soil guidelines, and the implications of registration of pesticides in Canada from an ecoregion perspective. In addition, we will address data-related issues, such as crop data, discuss the implications of using long-term versus short-term field data, and account for variability in climate and soil properties and the impact on site selection.
