| 摘要： | An emphasis of vegetation management on rights-of-way is to minimize environmental impact. For many people this means excluding the use of chemicals to kill and control vegetation, particularly synthesized products of chemicals that normally do not occur in nature (i.e., are artificial). An important part of Integrated Vegetation Management (IVM) is to research and demonstrate local effects of treatments, even those that include chemicals that may not work. A field trial of natural herbicides – which are perceived as chemicals that are acceptable to a broad spectrum of stakeholders – was conducted on New York State Department of Transportation roadside rights-of-way in 2010-2012. Randomized complete block experiments were established across New York State to test Burnout II (citric acid and clove oil active), C-Cide (citric acid), EcoEXEMPT HC (2-Phenethyl proprionate and clove oil), Finale (glufosinate ammonium), and Scythe (pelargonic acid). Percent kill of undesirable plants generally ranged from near zero to nearly 100% across the different natural herbicide treatments, and was related to the mode of action – herbicides that were contact-only in action resulted in the least degree of kill and control, whereas systemic herbicides were generally efficacious and effective. Costs of natural herbicide treatments were determined to be orders of magnitude greater than conventional herbicides. Despite low effectiveness and high dollar costs, it is important to have natural herbicides for use in select situations. Information on cost effectiveness allows ROW vegetation managers an opportunity to better understand and explain the ramifications of using natural herbicides. |
