Description of key information
One study was performed: FR-245: A Toxicity Test to Determine the Effects on Seedling Emergence and Growth of Six Species of Terrestrial Plants
Key value for chemical safety assessment
- Short-term EC50 or LC50 for terrestrial plants:
- 1 000 mg/kg soil dw
- Long-term EC10, LC10 or NOEC for terrestrial plants:
- 12.3 mg/kg soil dw
Additional information
In order to determine the effect of the test substance on the seedling emergence and growth, six species of terrestrial non-target higher plants were tested.
Results: A soil-incorporated application of FR-245 at nominal concentrations ranging up to 1000
mg/kg dry soil resulted in slight treatment related effects, but no reductions greater than 50% relative to the
control were observed on any test endpoint for any species. The EC50 for all six species tested was greater than 1000mg/kg dry soil.
NOEC for Allium cepa and Cucumis sativus was greater than 1000mg/kgdry soil. The NOEC for Lolium perenne
and Brassica alba was greater than 333mg/kgdry soil. The NOEC for Lactuca sativa was greater than 37mg/kg dry soil. The most sensitive species was Lycopersicon esculentum with an NOEC 12.3mg/kg dry soil.
