Additional information

The growth inhibitory effects of the test item to the duckweed Lemna minor were investigated according to OECD Guideline 221 under static conditions over a period of seven days. At the highest test concentration of 1000 mg/L active ingredient, no toxic effects were observed for any of the endpoints. At lower concentrations, a few statistically significant effects (maximum 23%) appeared in the data set, but no dose-response relationships could be observed for any of the end points considered.

In conclusion, the test item had no significant inhibitory effects on the duckweed Lemna minor at the nominal concentration of 1000 mg/L of its active ingredient under the conditions of the test.
