Evaluation of Glyphosate, Flumioxazin and Imazamox against Japanese Knotweed s. l.
Abstract
The purpose of this work was to evaluate flumioxazin and imazamox alone and in combination with glyphosate as potential alternatives for controlling Japanese knotweed at Times Beach, a 56-acre nature preserve located in Buffalo, New York. Times Beach is a 56-acre nature preserve located in Buffalo, New York. The site was initially constructed by the USACE Buffalo District as a confined disposal facility (CDF) in 1971. The CDF was partially filled and closed in 1976 at the request of the Ornithological Society of Buffalo (Simmers and Lee 1997). The site consists of three distinct ecological zones (aquatic, wetland and upland) and is utilized by more than 200 species of resident and migratory birds (Andrle 1986, Simmers and Lee 1997). Approximately 46 acres of Times Beach has been designated as a state wetland by the New York State Department of Environmental Conservation. Times Beach is located adjacent to the Buffalo River Area of Concern (AOC) and within the Niagara River Bi-national AOC. The site is dominated by invasive species such as phragmites (Phragmites australis (Cav.) Trin. Ex Steud.), Japanese knotweed (Polygonum cuspidatum Siebold & Zucc.), common buckthorn (Rhamnus cathartica L.) and mugwort (Artemisia vulgaris L.). The U.S. Army Engineer Research and Development Center in collaboration with the U.S. Army Corps of Engineers (USACE) Buffalo District developed an invasive species management and restoration plan for Times Beach. Removal of invasive species combined with enhancement of native plant communities will ultimately result in repaired ecosystem function. The Times Beach management and restoration plan was initiated in October 2012 with funding from the U.S. Environmental Protection Agency s (EPA) Great Lakes Restoration Initiative (GLRI). Because the majority of the site is classified as a state wetland, only aquatic herbicide formulations registered by the U.S. EPA and the state of New York can be applied.
