• This report is a guidance document on the estimation of toxicity of pesticide mixtures. The National Agri-Environmental Standards Initiative, a partnership between Environment Canada and Agriculture and Agri-Food Canada, commissioned the report to address uncertainty surrounding the pesticide mixtures question. While Ideal Performance Standards (IPS) guide the agricultural industry on acceptable levels of pesticides in the environment, the IPS are for individual compounds and do not address the common issue of pesticide mixtures. The report evaluates two models for predicting mixture toxicity: concentration addition and response addition. Literature studies, with accompanying toxicity data, were evaluated, and the report contains qualifiers and caveats for application of the two predictive models. The report recommends use of the concentration addition model; while both models were deemed effective, data quantity limitations in the literature for the response addition model make the concentration addition model the better default screening tool for pesticide mixture toxicity.
