| Abstract/Contents: | "Delayed or neglected maintenance of utility rights-of-way often necessitates the mechanical removal of tall-growing or access-restricting trees, brush, and woody vines. Mechanical removal of vegetation with one of several various devices provides immediate access and line clearance, but if a maintenance program is not established and followed, woody regrowth occupies the site within one or two years. Application of soil active woody plant herbicides became an accepted control method where soil type, terrain, and adjacent desirable vegetation made the technique practicable. Picloram became the treatment of choice because of its broad spectrum of species controlled, and its superior control of root-suckering species such as black locust (Robinia pseudoacacia L.), sassafras (S. albidum Nutt.), and aspen (Populus tremuloides Michx.). Applications were made using conventional broadcast sprays at volumes of 15 to 50 gal/A. A labeled application rate of 2 lb/A was widely used and accepted. Regulatory requirements changed the labeled rate of picloram for this use to 1 lb/A, making it necessary to look for satisfactory herbicide combinations. Ultra low volume (ULV) foliage applications using a thin invert emulsion on a spray system mounted on an ATV at a spray volume of 5 gal/A had been shown to be effective for control of woody plants. As a cut-stubble application following mechanical brush removal, a mixture of piclocram at 1 lb/A + imazapyr at 1/4 lb/A controlled 90% or more of typical brush on rights-of-way in the northeastern US. Commercial applications using this mixture and the ULV technique were made to utility transmission rights-of-way in 1999, 2000, 2001, 2002, and 2003. Evaluation of these applications in October of 2004 showed control as follows: [note=Table]. Species in the treated areas included various oaks (Quercus spp. L.), red maple (Acer rubrum L.), eastern redcedar (Juniperas virginiana L.), Sassafras, black locust, autumn olive (Eleagnus umbellata Thunb.), aspen, and black cherry (Prunus serotina Ehrh.)." |
