Abstract/Contents:"Basal herbicide applications provide the most directed, selective means for removing undesirable woody vegatation without affecting desirable woody and herbaceous species. Low-volume basal is becoming preferred and most widely used basal application technique. This application method involves application of 20 to 30 percent herbicide in an oil diluent to the entire circumference of the lower 12 to 15 inches of stem, including the root collar. Application should adequately wet the stem, but no runoff should occur. Low-volume basal application offers numerous advantages compared to other basal techniques which require larger quantities of oil-based diluents. These include: (1) potential savings in diluent costs, (2) increased labor efficiency because the applicator makes fewer return trips to the mixing truck to refill the backpack tank, (3) low-profile application with minimum odor because much less oil diluent is applied per acre, (4) minimized site compaction and erosion potential because large mixing trucks are not required on the rights-of-way, and (5) less oil-based carrier introduced into the environment. Low-volume basal application of triclopyr (4 lb ae/gallon) and a product combining picloram ester (1 lb ae/gallon) and triclopyr ester (2 lb ae/gallon) has been demonstrated to be viable, efficacious tool for controlling undesirable woody plants. Dormant and growing season trials were established in 1984 and 1985 at several locations to test low-volume basal application of various picloram/triclopyr ratios in herbicide mixtures. All treatments were applied with a backpack sprayer equipped with low-volume wand and adjustable solid cone nozzle. Major species treated included black cherry (Prunus serotina Ehrh.), maple (Acer spp.), oak (Quercus spp.), sassafras (Sassafras albidum Trew.), birch (Betula spp.), white ash (Fraxinus americana L.), and aspen (Populus tremuloides Michx.). Second year results of 1985 applications indicate that all treatments provided at least 84 percent control of all tree species. A small number of black cherry, oak, and sassafras resprouted after some treatments. Generally, sprouting increased as the relative amount of picloram decreased. Field observations suggest that control of root-suckering species during early dormant season (November through February) applications is improved by the addition of picloram."
