• 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.
