Subform VII: Scientific Study

1. Study Reference

Title Pseudokirchneriella subcapitata growth inhibition test with ethofumesate-NC8493 (AE C508493)

Date 03-AUG-12

2. a) Is an extension needed to translate the document?

No

3. Type of incident identified in the study

Increased health or environmental risk

4. Describe the incident identified in the study (e.g. study demonstrates an increased risk to non-Hodgkin's Lymphoma after exposure to pesticide X)

The study of the degradate with green algae indicates NC8493 (primary metabolite) is more toxic than the parent compound (ethofumesate). However, the measured endpoints for both the parent compound and its degradate NC8493 are higher than the Expected Environmental Concentrations (EECs).

5. a) Was the study discontinued before completion?

No

5. b) Provide the reason for discontinuation

6. If the study is ongoing, what is the expected completion date?

For Registrant use only

7. Provide supplemental information here

The endpoint values in the freshwater algae study were originally evaluated in the EPA risk assessment for ethofumesate. Therefore, this study information does not impact the current risk assessment for Canada.
