Materials and methods
Test guideline
- Qualifier:

- not specified
- Test type:
- other: acute tox by gavage on chickens, control on larvae: LD50 calculated by probit analysis
Test material

- IUPAC Name:
- 3,5,6-trichloro-2-pyridinol sodium salt
- Details on test material:
- Purity of pyridinol-salt was tested by thin-layer chromatography.

Applicant's summary and conclusion
- Interpretation of results:
- other: classification not possible from the reasults given in the publication
- Remarks:
- Criteria used for interpretation of results: expert judgment
- Conclusions:
- Classification not possible from the results given in the publication. However, given the high dosis compared to the low mortality, the material may be considered harmful.
