1. Which of the following is the primary purpose of right-of-way pest
control?
A. Enhancing aesthetic value of roadside vegetation
B. Protecting utility lines and transportation corridors from
vegetation interference
C. Increasing wildlife habitat
D. Improving soil fertility
B
Rationale: Right-of-way pest control focuses on preventing
vegetation from interfering with transportation corridors, power
lines, pipelines, and other infrastructure. Safety and accessibility
are the main concerns rather than aesthetics or soil improvement.
,2. What is the main environmental concern when applying
herbicides along right-of-ways?
A. Soil compaction
B. Water contamination from runoff
C. Excessive wildlife attraction
D. Increased air humidity
B
Rationale: Runoff from herbicide applications can contaminate
nearby streams, rivers, and groundwater. Proper application
methods are essential to minimize environmental risks.
3. Which herbicide application method delivers the most precise
control to individual plants along power line corridors?
A. Aerial spraying
B. Basal bark application
C. Broadcast spraying
D. Soil injection
B
Rationale: Basal bark applications allow herbicide to be applied
directly to the lower trunk and stem, reducing drift and targeting
specific woody plants without affecting non-target vegetation.
,4. What is a common problem associated with mechanical control
methods along right-of-ways?
A. They are ineffective against all types of vegetation
B. They always require herbicides afterward
C. Soil disturbance can lead to erosion and invasive species
colonization
D. They are illegal in most states
C
Rationale: Mechanical methods like mowing, cutting, or grubbing
can disturb soil, which may promote erosion and create openings
for invasive species to establish.
5. When selecting a herbicide for right-of-way control, which factor is
most important?
A. Cost per gallon
B. Mode of action and target species
C. Manufacturer reputation
D. Container color
B
Rationale: Choosing the correct herbicide requires matching the
chemical’s mode of action to the target vegetation while
minimizing risk to non-target species.
, 6. Which of the following is an advantage of using selective
herbicides on right-of-ways?
A. They control all vegetation equally
B. They reduce harm to desirable grasses while targeting specific
weeds
C. They require higher application rates
D. They increase the need for mowing
B
Rationale: Selective herbicides target specific plant types, allowing
desirable vegetation to remain, which helps prevent erosion and
maintains ecosystem balance.
7. Which protective equipment is required when applying herbicides
to right-of-way trees?
A. Hard hat, gloves, eye protection, and chemical-resistant
clothing
B. Only gloves and boots
C. Safety goggles and hard hat only
D. No protective equipment if the herbicide is low toxicity
A
Rationale: PPE reduces the risk of chemical exposure, skin contact,
and inhalation. Right-of-way work often involves close contact
with chemical sprays and woody plants.
