| dc.description.abstract | Purple loosestrife (Lythrum salicaria) is an exotic wetland weed that rapidly displaces native vegetation resulting in monotypic stands that reduce vegetative diversity and degrade wildlife habitat. Use of nonchemical management techniques, e.g., flooding, draining, cutting, and burning, is inherently nonselective and seldom results in long-term control of purple loosestrife infestations. Some herbicides offer a selective technique for reducing Purple loosestrife levels, eradicating pioneer colonies of the plant, and restoring native wetland communities. The objectives of this study were to evaluate effectiveness of the herbicide triclopyr on Purple loosestrife, and to monitor changes in the plant community following triclopyr treatment. Stands of Purple loosestrife, located in the Upper Mississippi National Wildlife and Fish Refuge, MN, were treated with an amine formulation of triclopyr (Garlon 3A) on 30 June 1992. Application rates were 0.75 and 1.0 percent Garlon 3A. Percent cover of Purple loosestrife and associated plant species were monitored using line-intercept techniques pretreatment, and at 10 weeks and 2 years posttreatment. Results showed that Garlon 3A is an effective product for significantly reducing purple loosestrife cover; however, seedling recruitment can be expected. Although data showed no significant differences between rates tested, areas treated with the higher rate had less regrowth. This research resulted in a chemical technique for controlling Purple loosestrife in wetland communities that includes minimizing damage to nontarget plants, particularly monocots, while offering a potential for restoring a diverse plant community. | en_US |
