Measures/Label Changes for Risk Quotient Reduction”. The agreed upon

mitigation measures for each crop are shown on the green-shaded rows.

 “Table 2. Triflumizole Occupational Exposure – Agreed Upon Mitigation

Measures/Label Changes for Exposure Reduction”. Agreed upon new mitigation

measures, as stipulated in the revised Human Health Risk Assessment, dated
