Description of key information

IC50 (14-day): 209 mg/kg dry weight, root dry mass, Hordeum vulgare, reliability 2

EC50 (14-day): >4054 mg/kg dry weight, seedling emergence, root and shoot length and root and shoot dry mass, Trifolium pratense, reliability 2

Key value for chemical safety assessment

Short-term EC50 or LC50 for terrestrial plants:
209 mg/kg soil dw

Additional information

A 14-day IC50 value of 209 mg/kg dry weight has been determined for the effects of the test substance on root dry mass of Hordeum vulgare. IC50/EC50 values for effects on seedling emergence, root and shoot length and shoot dry mass determined in the same test were ≥248 mg/kg dry weight. 14-day EC50 values of >4054 mg/kg dry weight have been determined for the effects of the test substance on seedling emergence, root and shoot length and root and shoot dry mass of Trifolium pratense. NOECs were not determined in the tests.

A long-term toxicity study with terrestrial plants has not been carried out as the Chemical Safety Assessment indicates that this is not necessary.
