Considerations for Using Herbicides for Aquatic Weed Control in Domestic Water Supplies of North Carolina

摘要

The purpose was to demonstrate the feasibility of safely using herbicides for aquatic weed control in domestic water supplies and to produce a readily available source of public information concerning the fate and environmental risk of diquat, endothall and fluridone for small-area aquatic weed control in large domestic water supply lakes. The project included a review of literature on persistence and mammalian toxicities of the three herbicides, a field study of their persistence in North Carolina ponds, and a study of flow patterns and dilution rates that could affect herbicide concentrations and movement in Lake Wheeler.
