• Abstract:
  The objective of the project was to investigate the potential of using the weed wiper applicator ; as an alternative method to mowing and broadcast spraying for controlling noxious weds, brush and ; plant growth along roadways. An existing weed wiper applicator used for tax ditch herbicide ; applications was modified by replacing a flat set of applicators which utilized grit abrasive banded to ; an aluminum channel with radial applicators. The chemicals Roundup, Rodeo, Touchdown and ; Arsenal were used. They were applied in concentrated and dilute form or as mixtures. Applications ; of Rodeo, Roundup and Touchdown at the rate of 0.3 gallons per acre were 50 to 75% effective on 1 ; to 2 year old sweet gum, tulip popular, sumac, cherry and maple with one application. With the ; addition of 1 part of applicators concentrate Arsenal added to 40 parts of the other chemicals and ; applied at 0.25 gallons per acre, vegetation control was over 75% with one application. Even ; vegetation with extensive root systems was controlled and pine, cedar, willow, phragrnites, multiflora ; rose, black locust, holly and sassafras were also controlled in varying degree with one application. ; The total capital cost for a complete three tank applicator system not including the tractor is ; estimated to be in the $10,500 range. The cost for roadside utility right-a-way and roadside ditchwood ; line spraying are in the range of $190 to $200 per mile. This cost includes labor, equipment ; and chemicals.
