Description of key information

In non-guideline studies with three different types of pondweed (Pontamogea crispus, Pontamogea lucens, and Pontamogea coloratus) the inhibition of photosynthesis was studied. These studies were disregarded ue to methodological deficiencies. Most test conditions were not indicated. No information about application mode, number of plants, controls, or test concentrations are given. Observed 14d-NOEC of 1.08 mg/L (Pontamogea crispus and coloratus) and 0.22 mg/L (Pontamogea lucens) were derived. However, no detais on analytics or statistical mehtods to derive these values are given.
