RT Journal Article SR Electronic T1 Vegetation Management Along Transmission Utility Lines in the United States and Canada JF Arboriculture & Urban Forestry (AUF) JO JOA FD International Society of Arboriculture SP 198 OP 205 DO 10.48044/jauf.2000.023 VO 26 IS 4 A1 Joseph A. Sulak A1 J. James Kielbaso YR 2000 UL http://auf.isa-arbor.com/content/26/4/198.abstract AB A survey investigating vegetation control methods along transmission rights-of-way was sent to 220 Utility Arborist Association companies. The survey contained questions regarding right-of-way characteristics, control methods used, total dollars spent on vegetation management, and priorities of the vegetation management program. The ROW area reported represented over 48% of all the investor-owned ROWs over 39 Kv in service throughout the United States. More than 75% of the respondents reported using herbicides on their rights-of-way. However, acres treated mechanically outnumbered those treated chemically by a margin of 2.7:1. Garlon 3A and Garlon 4 topped all herbicides, with a combined 220,574 projected gal (834,961 L) of the estimated 549,869 gal (2,081,474 L) of herbicide applied to transmission rights-of-way in 1995. It appears that quite low levels of active ingredients are being applied per acre. Basal, high-volume foliar, and low-volume foliar with a backpack or handgun applications accounted for approximately 75% of the acres of transmission ROWs treated with herbicides.
