The Minnesota Department of Transportation (Mn/DOT) has been active in developing the best technology for roadside vegetation control. One method, herbicide spraying, helps eliminate unwanted vegetation. Treatment of unwanted weeds often requires the use of different herbicides. Sprayers must have the capacity to spray more than one chemical at a time, negotiate rough terrains, and apply herbicides safely and in a way that preserves the environment. This report presents the results from testing and evaluating four automated sprayers: The B&B Ditch Sprayer 300 Prototype, a Wanner Innovative Sprayer, the Micro-Track Spray Sytem, and the SCS 750. All four tested sprayers are more economically feasible that the tradiational sprayer. The B&B Ditch Sprayer has the lowest net annual savings of the four tested sprayers. The Wanner Sprayer is more economical for use in large districts or in areas with extensive road miles. The Micro-Track Sprayer has the highest rate of return, and also reduces annual costs. The SCS Sprayer has the highest net annual savings and also can monitor, tabulate, and print all vital statistics. The report details product features, testing, and results. |
