Project Detail

UNIVERSITY OF WISCONSIN-MADISON: Determining fate of the novel herbicide florpyrauxifen-benzy

Purpose

The Board Of Regents of the University of Wisconsin System is sponsoring a project to conduct an aquatic invasive species research study on the degradation of florpyrauxifen-benzyl [FPB] following herbicide treatments conducted for aquatic plant management in Wisconsin lakes. The project aims to determine the mechanisms responsible for FPB breakdown in lakes by: 1) quantifying both direct and indirect photolysis of FPB in lake water using lab experiments; 2) quantifying FPB degradation in water-only and water-sediment environments; 3) determining the primary degradation pathway of FPB following in field applications; and 4) quantifying FPB persistence and degradation products post treatment in lakes. Project deliverables include: Data on the relative importance of both direct and indirect FPB photodegradation; data on microbial degradation of FPB in water and sediment matrices; data on the spatial distribution and persistence of FPB in water and sediment following aquatic plant control activities in lakes. Special Conditions: Quarterly reports and a final report summarizing these findings will be submitted to WDNR. WDNR will meet with sponsor periodically during project to discuss progress on deliverables and overall project goals.
