The New Standard for Aquatic Weed Control in Canals

Sonar* A.S. is a systemic aquatic herbicide that has been effectively used since 1986 to control submersed aquatic weeds in a variety of aquatic environments, including freshwater lakes, ponds, potable water reservoirs, rivers and canals.

Over the past ten years, Sonar A.S. has proven to be an effective tool for managers targeting submersed aquatic weeds in ponded or static canals. In 2007, the United States Environmental Protection Agency (EPA) approved a new label amendment allowing the application of Sonar A.S. to dry or dewatered canals. This new application technique provides canal managers a cost effective and flexible pre-emergent solution to annual aquatic weed control.
