Applicant's summary and conclusion
- Conclusions:
- The test was conducted with the analogue substance. As a result of the test, the analogue substance has an EC50 of 228 mg/L (after 24 h). Due to the structural similarity and comparable bioavailability of both substances, the EC50 value for the substance subject of registration is expected to be in a comparable range.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
