Esplanade 5 oz./ac + Glyphosate 13 oz./ac + Surf. Oct. 25 – Nov. 25, 2017 application Dutton district
Good Economic Information I-59 Guard rails for one ALDOT district 27.88 miles string trimming cost $16,000 (about $475/ac.). This can be done up to 3 times/year. Substituted one (1) fall Esplanade 5 oz./ac + Glyphosate 13 oz./ac with labor/equipment cost = $1,550 (Used 1.32 gallons of Esplanade 200SC) Maintained weed control and line-of-sight for the entire year without the need for string trimming.
Cable Barrier and Guardrail Treatment Comparisons (ALDOT) It would take 17 years of annual weed trimming to break even comparing the cost of the concrete pad installation It would take 53 years of annual Esplanade applications to break even comparing the cost of the 1 year of line trimming. It would take 875 years of annual Esplanade applications to break even comparing the cost of the concrete pad installation. (Comparing 5 ft. wide swath for 1 mile)

Benefits If planned and managed properly the District should: Reduce the interaction between mowers and the traveling public (increased safety) Reduce mower damage to slopes and appurtenances Have mowing funds that can be spent elsewhere in the District Have labor to redirect to other District needs Estimates ranged from 5 to 7 weeks for a 5 man crew Increase the appearance of the District roadsides and, over time, see an increase in the District condition assessment scores
