M. Essam Dabaan The Kentucky Pesticide Impact Assessment Program in association with the Vegetation Management Association of Kentucky conducted a mail survey in early 1997 to learn more about specialized herbicides and plant growth regulators used on rights-of-way in Kentucky. Eighteen usable responses were received from the original group of 46 vegetation managers, resulting in a 39 percent response rate. Results Summary: Woody plants received the most pesticide applications of the five vegetation types listed in the questionnaire (herbaceous plants, grassy weeds, broadleaf weeds, woody plants, and no vegetation). Estimates of application costs were $150 and more per acre per growing season, and all of these applications were for woody plants. Broadleaf weeds were the most targeted pest. The most used application method was a high/low volume spray. Twenty-nine products were reported as being used for vegetation management. (See Table) Table: Pesticides used, cost/acre, and alternatives
- In terms of frequency of use, the most commonly used products were Arsenal, Accord, Roundup, and Garlon, comprising 13.5, 12.5, 11.5, and 10.4 percent (respectively) of total usage. - In terms of acreage treated, the most used products were 2,4-D, MSMA, Telar, Escort, and Fusion (applied to almost 68 percent of the reported acreage). |
