Abstract : A program for the management of the nonnative aquatic plant Eurasian watermilfoil (Myriophyllum spicatum L.) is proposed for waters within the State of Washington. The proposed program is designed to prevent the spread of milfoil to uninfested navigable waters and to control existing milfoil growth at high- use public areas in navigable waters. Monitoring of any proposed chemical treatment methods utilized and evaluation of the overall effectiveness of the Aquatic Plant Management Program are incorporated as project features. Treatment methods which are acceptable for use in prevention and control operations are: (1) Prevention - Rotovating, hand removal, suction dredging, fragment barriers, or the herbicide 2,4-D. (Aerial surveillance, ground surveillance, and public information will also be utilized by the prevention program); and (2) Control - Mechanical harvesting, fiberglass bottom screens, 2,4-d, endothall, diquat, or dichlobenil. The methods or combination of methods that may be utilized are specific to each site proposed for treatment and would be determined by the local sponsor. (Author)
