Honeybee acute and oral studies were performed on an suspension concentrate (SC) mixture formulation of spirotetramat and thiacloprid. This report is being submitted because it may meet the conditions as described by the Guidance Document for the Pest Control Products Incident Reporting Regulations demonstrating an effect at levels 50% or more lower than previous acute toxicity studies.

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

While technically the endpoints may meet the reporting criteria, there are no registered mixture formulations of spirotetramat and thiacloprid in Canada and therefore the information is irrelevant to the risk assessment.
