Applicant's summary and conclusion

Validity criteria fulfilled:
yes
Conclusions:
14-day LC50 (earthworms) > 1000 mg (a.i. as total solids)/kg dry weight soil.
14-day NOEC (earthworms) > 1000 mg (a.i.as total solids)/kg dry weight soil.
Executive summary:

The acute toxicity of the test substance to earthworms, Eisenia fetida, was estimated in a 14-day soil exposure laboratory study conducted under OECD Guideline 207 in artificial soil. Based on the results of a range-finding test, a Limit Test was conducted. The 14-day LC50 and NOEC were determined to be greater than 1000 mg (a.i. based on total solids)/kg dry weight soil.
