LOW-IMPACT, SELECTIVE CONTROL OF MESQUITE ON RIGHTS-OF-WAY. OBJECTIVE 1: ECONOMIC THRESHOLDS FOR HONEY MESQUITE REGROWTH CONTROL WITH SELECTED INDIVIDUAL PLANT TREATMENTS. INTERIM REPORT

Honey mesquite regrowth on highway rights-of-way was treated with four individual plant treatments (stem spraying with Pathfinder II or 15% Garlon 4 + 85% diesel; leaf spraying with 0.5% Garlon 4 + 0.5% Transline using backpack sprayers or an all-terrain vehicle-sprayer) to determine the economic feasibility and labor requirements of these methods. Mesquite density accounted for 95% or more of the variability in total cost/acre for all four methods. Mesquite densities on highway rights-of-way were highly variable (average = +/-324 plants/acre; range = 18 to >1,000 plants/acre). For the average mesquite density scenario, all four methods, even at a labor cost of $20.71/hour, would substantially reduce right-of-way maintenance costs, compared to annual mowing, over a 10-year planning horizon. Total costs, labor requirements, and herbicide deposition in the environment would be greatly minimized by selection of the leaf spray methods. The variability in labor costs for highway maintenance personnel among counties and the variability in mesquite densities suggest that several methods, including broadcast spraying, may be viable treatment alternatives for long-range right-of-way maintenance programs.
