MATF is used to calculate the toxicity of pesticides for the ‘Healthy Grown’ Wisconsin Potato IPM Labeling Project. The MATF indicator ranks toxicity data in order to generate toxicity factor scores for beneficial organisms and humans. It then multiplies these scores by the pesticide’s application rate in order to produce toxicity units for each application, with more toxicity units indicating more potential risk (Benbrook et al., 2002).
