| 摘要： | Operational treatment of roadside vegetation under and near guide-rails in the Route 80 corridor along Otsego Lake was completed by NYSDOT in July 2014 using a natural herbicide – Scythe. A total of 8 miles of roadside right-of-way, and specifically 1.4 acres and 3.8 miles of guide-rails, were treated with 296 gallons of herbicide mix with 10% Scythe. Herbicide materials were jointly purchased by the Village of Cooperstown and the NYSDOT at a total cost of $1,954. Vegetation conditions before and after treatment, and percent of plants directly damaged by the herbicide, were monitored by a third-party (SUNY-ESF) using a network of 30 2 x 2 foot measurement plots located across the area. Plots received varying coverage of herbicide treatment due to problems with machinery and spray pattern, with percent of plants directly damaged by herbicide averaging 51 percent, ranging from 0 to 95 percent. Regression analyses were used to test various relationships between end-of-growing plant cover and percent of plant damage. On average and as estimated across all 30 plots using regression techniques, Scythe herbicide was observed to reduce plant abundance to a total cover of 12 percent, compared to 62 percent cover with no Scythe herbicide treatment. Vines or Japanese knotweed were shown to not be affected by Scythe treatment. Operational results are similar to those observed with recent field trials with research in Massachusetts and New York. In contrast to NYSDOT normal, conventional herbicide treatment with glyphosate-based herbicide such as Accord XRT II, which would have had a total materials costs of only $18 and expected 100 percent control of vegetation, the Scythe herbicide cost 100 times more and still left 12 percent cover of plants, with effectively no control of vines or knot-weed. |
