1. What is the primary goal of right-of-way (ROW) vegetation
management?
A. Increase ornamental plant growth
B. Maintain safe, unobstructed areas for transportation and
utilities
C. Maximize wildlife habitat
D. Eliminate all plant life permanently
Rationale: Right-of-way pest control focuses on keeping roadsides,
railways, and utility areas clear for safety, visibility, and infrastructure
protection, not total vegetation removal or ornamental growth.
2. Which herbicide is commonly used for broad-spectrum, non-
selective vegetation control in ROW areas?
A. 2,4-D
B. Dicamba
C. Glyphosate
D. Atrazine
Rationale: Glyphosate is a systemic, non-selective herbicide widely
used in ROW vegetation management to control grasses and
broadleaf plants.
, 3. What is the most important factor to check before applying any
pesticide?
A. Weather forecast
B. Equipment brand
C. Pesticide label instructions
D. Soil type
Rationale: The pesticide label is a legal document that must be
followed exactly and provides critical application and safety
information.
4. Which application method is best for controlling woody brush in
ROW areas?
A. Broadcast spraying
B. Dusting
C. Soil drenching
D. Basal bark application
Rationale: Basal bark application delivers herbicide directly to the
lower stems of woody plants, making it effective for brush control.
5. What does “REI” stand for on a pesticide label?
A. Restricted Equipment Instructions
B. Recommended Exposure Interval
C. Restricted Entry Interval
D. Residual Effect Indicator
Rationale: REI is the time period after application during which
workers must not enter treated areas without PPE.
, 6. Which condition increases the risk of pesticide drift?
A. Low temperature
B. High humidity
C. High wind speed
D. Cloudy skies
Rationale: Strong winds can carry pesticide droplets away from the
target site, causing drift and off-target damage.
7. What is the main purpose of adjuvants in herbicide applications?
A. Replace herbicides
B. Reduce cost
C. Improve performance of the herbicide
D. Neutralize toxicity
Rationale: Adjuvants enhance spreading, sticking, or penetration of
herbicides to improve effectiveness.
8. Which herbicide mode of action inhibits amino acid synthesis?
A. Photosystem II inhibitors
B. Lipid synthesis inhibitors
C. EPSP synthase inhibitors
D. Growth regulators
Rationale: Glyphosate inhibits EPSP synthase, blocking essential
amino acid production in plants.
9. What is the best way to prevent pesticide resistance?
A. Increase dosage repeatedly
