Figure 1. Species sensitivity distribution for aquatic plants exposed to diquat. The straight line represents the model fit to all of the data (y = 11.285ln(x) + 83.41; R2 = 0.9373). *Maximum target concentration for Reward® is 0.4 mg/L, indicating a lack of a margin of safety for approximately 74% of species. **Maximum target concentration for Weedtrine-D® is 1.5 mg/L, indicating a lack of a margin of safety for approximately 88% of species.
