DNR-WATERSHED MGMT: Aquatic Herbicide Research/Smart Prevention GIS Support


The DNR Bureau of Watershed Management proposes to support research by the US Army Corp of Engineers researchers on aquatic herbicide residues on various lakes in Wisconsin and in mesocosm trials, which will improve our understanding of the environmental conditions effect on efficacy of herbicide use to control exotic aquatic species and promote natives. The project activities include: 1. Sampling herbicide residues to refine treatment recommendations in a variety of scenarios, 2. Compare efficacy of liquid and granular 2,4-D and Triclopyr on Eurasian and hybrid milfoil. Deliverables for this grant include a final report summarizing results from various projects and trials (both paper copy and an electronic copy), which will serve as guidance for operational use of herbicides for aquatic plant management. Findings will be submitted to DNR and posted on the internet.

Reports and Documents
In 2009 the ERDC and the Wisconsin (WI) Department of Natural Resources (DNR) formed a Cooperative Research and Development Agreement (CRADA) to conduct herbicide residual monitoring on large scale herbicide applications in WI from 2009 to 2010. The objective was to provide information regarding actual herbicide concentration and exposure time data for herbicide applications under a variety of operational conditions and develop recommendations for improved control of invasive exotic aquatic plant species and reduced damage to native plant populations.
