Montana Right-of-Way, Rangeland, Non-Crop, and Regulatory Weed Initial Certification


Right-of-Way, Rangeland, Non-Crop, and Regulatory Weed
Initial Certification

Course Description

The right-of-way applicator in Montana must demonstrate practical knowledge of a wide variety of environments, excessive foliage destruction, and the ability to recognize target weeds. Right-of-way applicators must also demonstrate practical knowledge of the nature of herbicides, the need for containment, and the impact of their application activities in the adjacent areas and communities. It is strongly suggested that the study manual for this certification be used with this training to maximize preparation for the exam. Click here to visit the Montana Department of Agriculture website to purchase study manuals that correlate to this training module and exam preparation.

To simplify information, trade named products, and equipment have been mentioned. No endorsement is intended, nor is criticism implied, of similar products or equipment, which are not mentioned.

After completing this course participants will be able to:

  • Demonstrate practical knowledge of the nature of herbicides.
  • Articulate the need for containment of pesticides within the right-of-way areas.
  • Outline the impact of application activities on areas and communities adjacent to right-of-way areas.
  • Identify common right-of-way pests and weeds.
