Frequency distribution of model distribution ratios (MDR) for fungicidal combination products. MDR was calculated based on the data set "most similar endpoints" using non-censored data only. Black represents products containing active substances with similar and white those with at least two active substances with dissimilar pesticidal modes of action. MDR values smaller than 1 indicate that the product is less and MDR values greater than 1 indicate that the product is more toxic than predicted, respectively. A, algal growth inhibition (n = 49); B, Daphnia acute toxicity (n = 43); C, fish acute toxicity (n = 42); D, Daphnia chronic toxicity (n = 14); E, fish chronic toxicity (n = 13).
