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.
