INTRODUCTION
The Alabama Category 6 Right-of-Way Pest Control examination assesses the knowledge and skills
required to safely and legally manage vegetation along roadsides, utility corridors, railways, and
pipelines. Candidates must demonstrate competency in integrated vegetation management, herbicide
selection, application techniques, calibration, environmental protection, and regulatory compliance. The
exam employs multiple-choice and scenario-based questions designed to evaluate real-world application
and professional decision-making. Emphasis is placed on safety, environmental stewardship, and
adherence to FIFRA and Alabama Department of Agriculture and Industries standards. This assessment
prepares applicators for certification and responsible practice.
SECTION ONE – QUESTIONS 1–100
Question 1
What is the primary purpose of right-of-way pest control?
A. Increase crop yield
B. Protect transportation and utility corridors
C. Improve soil fertility
D. Control indoor pests
🟢 B. Protect transportation and utility corridors
🔴 Explanation: Right-of-way pest control focuses on maintaining vegetation along roadsides,
railways, and utility corridors to ensure safety, access, and infrastructure protection rather than
agricultural or residential pest management.
,Question 2
Which federal law regulates pesticide registration, labeling, and use in the United States?
A. Clean Air Act
B. Endangered Species Act
C. Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)
D. Occupational Safety and Health Act
🟢 C. Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)
🔴 Explanation: FIFRA governs the registration, labeling, distribution, and use of pesticides. It is the
primary federal statute that applicators must comply with during right-of-way operations.
Question 3
What is the primary goal of Integrated Vegetation Management (IVM) in right-of-way settings?
A. Eliminate all vegetation permanently
B. Combine multiple control methods for sustainable, low-growing vegetation
C. Apply herbicides on a fixed calendar schedule
D. Maximize tree growth for wildlife habitat
🟢 B. Combine multiple control methods for sustainable, low-growing vegetation
🔴 Explanation: IVM integrates chemical, mechanical, biological, and cultural controls to maintain safe
corridors while promoting stable, low-growing plant communities that reduce long-term maintenance
needs.
Question 4
Which of the following is a contact herbicide?
A. Glyphosate
B. Imazapyr
C. Diquat
D. Triclopyr
🟢 C. Diquat
🔴 Explanation: Diquat is a contact herbicide that injures only the plant tissue it directly contacts. It
does not translocate within the plant, unlike systemic herbicides such as glyphosate or triclopyr.
Question 5
A right-of-way applicator notices that a tank mixture has formed precipitates. What is the most
appropriate action?
A. Apply the mixture immediately to avoid waste
B. Add more surfactant to dissolve the precipitate
C. Stop mixing, do not apply, and dispose of the mixture properly
D. Strain the mixture and continue
🟢 C. Stop mixing, do not apply, and dispose of the mixture properly
,🔴 Explanation: Precipitation indicates incompatibility that can reduce efficacy and damage
equipment. The mixture must not be applied and should be disposed of according to label and local
regulations.
Question 6
Which weather condition most increases the risk of pesticide drift?
A. Calm wind and high humidity
B. Moderate wind blowing toward sensitive areas
C. High wind or gusty conditions
D. Overcast skies with low temperature
🟢 C. High wind or gusty conditions
🔴 Explanation: High wind carries spray droplets away from the target area, increasing the potential
for off-target damage to sensitive vegetation, water, or people.
Question 7
What is the function of a surfactant in herbicide application?
A. Kill insects directly
B. Improve spray coverage and absorption on plant surfaces
C. Neutralize soil pH
D. Reduce herbicide toxicity
🟢 B. Improve spray coverage and absorption on plant surfaces
🔴 Explanation: Surfactants reduce surface tension, allowing herbicide sprays to spread evenly across
leaf surfaces and enhance absorption through plant tissues.
Question 8
Which document contains legally enforceable pesticide use instructions?
A. Company safety newsletter
B. Pesticide label
C. Equipment catalog
D. Safety Data Sheet
🟢 B. Pesticide label
🔴 Explanation: The pesticide label is a legal document that applicators must follow. It contains
directions for use, restrictions, precautions, and personal protective equipment requirements.
Question 9
A roadside manager is selecting herbicides for a site adjacent to a stream. Which approach minimizes
off-target movement?
A. High-pressure broadcast application
B. Coarse droplet directed application with buffer zones
, C. Aerial application during windy conditions
D. Fogging with ultra-low volume
🟢 B. Coarse droplet directed application with buffer zones
🔴 Explanation: Coarse droplets reduce drift, and buffer zones prevent pesticide movement into
sensitive aquatic areas. Directed application ensures the herbicide reaches only the target vegetation.
Question 10
Which vegetation type presents the greatest safety hazard along roadways?
A. Low-growing grasses
B. Ground cover legumes
C. Tall woody shrubs and trees
D. Annual broadleaf weeds
🟢 C. Tall woody shrubs and trees
🔴 Explanation: Tall woody vegetation obstructs driver sightlines, interferes with utility infrastructure,
and creates recurring clearance and reliability concerns along transportation corridors.
Question 11
What is the primary concern when applying herbicides near utility poles?
A. Increasing herbicide runoff
B. Preventing damage to desirable vegetation and infrastructure
C. Reducing soil fertility
D. Attracting wildlife
🟢 B. Preventing damage to desirable vegetation and infrastructure
🔴 Explanation: The goal is to remove unwanted vegetation while avoiding damage to desirable
plants and preventing herbicide contact with utility structures that could compromise safety.
Question 12
Which mechanical method is commonly used for vegetation control on steep roadside slopes?
A. Aerial herbicide application
B. Soil fumigation
C. Mechanical mowing or brush cutting
D. Foliar spraying of tall trees
🟢 C. Mechanical mowing or brush cutting
🔴 Explanation: Steep slopes can be unsafe for herbicide application. Mechanical methods allow safer
control of vegetation without the risk of drift or runoff on difficult terrain.
Question 13
What does the term "selective herbicide" mean?
