Description of key information
Frond number, growth rate:
EC50 > 100 mg/l
NOEC = 100 mg/l
Key value for chemical safety assessment
Additional information
OECD guideline 221.
A preliminary test was run, using nominal concentrations of 10, 100 and 500 mg/l of a.i. and control. Test concentartions were found to be stable over the whole study period, thus nominal values were taken into account. No significant effects were seen, thus the definitive test was performed as limit test at 100 mg/l as a.i.. After a 7 -day exposure, EC50 as growth rate of both frond number and yield was above 100 mg/l as nominal concentration of a.i..
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
