B. Maintain safe and unobstructed transportation and utility corridors
C. Eliminate all plant life permanently
D. Promote ornamental plant growth
Answer: B. Maintain safe and unobstructed transportation and utility
corridors
Rationale: Right-of-way management focuses on safety, visibility,
and infrastructure protection, not total vegetation removal.
2. Which herbicide application method is most commonly used along
roadsides?
A. Soil fumigation
, B. Foliar spray
C. Seed treatment

Answer: B. Foliar spray
Rationale: Foliar sprays are efficient for controlling broad vegetation
over large linear areas like roadsides.

A. Insecticide Production Method
B. Integrated Pest Management
C. Intensive Plant Monitoring
D. Internal Pest Mitigation

handling herbicides?
A. Ear plugs
B. Chemical-resistant gloves
C. Steel-toe boots only
D. Sun hat
Answer: B. Chemical-resistant gloves

9. What is herbicide resistance?
A. Plants becoming larger
