1. Which of the following is the primary goal of right-of-way pest
control?
A. Increase plant growth for landscaping
B. Protect public health, safety, and infrastructure
C. Enhance wildlife habitats
D. Maximize pesticide sales
B. Protect public health, safety, and infrastructure
Rationale: Right-of-way pest control focuses on maintaining safe,
accessible, and functional utility corridors, roadsides, and railways,
rather than enhancing plant growth or wildlife habitats.
,2. What is the most common method of herbicide application along
rights-of-way?
A. Soil injection
B. Foliar spray
C. Seed coating
D. Trunk injection
B. Foliar spray
Rationale: Foliar sprays target the leaves of weeds and unwanted
vegetation, which is efficient for controlling large areas along rights-
of-way.
3. Which of the following is an advantage of using selective herbicides?
A. They kill all vegetation indiscriminately
B. They target specific weed species while leaving desirable plants
unharmed
C. They are always cheaper than non-selective herbicides
D. They require no protective equipment
B. They target specific weed species while leaving desirable plants
unharmed
Rationale: Selective herbicides allow control of specific plant species
without damaging other vegetation, which is critical along roadsides
where desirable plants or trees may be present.
4. When applying herbicides near a waterway, which practice is most
important?
, A. Increase dosage to compensate for water
B. Avoid drift and runoff into water
C. Apply during heavy rain
D. Mix with fertilizer
B. Avoid drift and runoff into water
Rationale: Protecting water quality is essential; herbicides should not
contaminate streams, rivers, or wetlands.
5. What does the term “integrated vegetation management” (IVM) refer
to?
A. Only using chemical herbicides
B. Combining mechanical, chemical, and cultural methods to manage
vegetation
C. Planting only native species
D. Avoiding all vegetation control
B. Combining mechanical, chemical, and cultural methods to manage
vegetation
Rationale: IVM uses multiple techniques to manage vegetation
effectively while minimizing environmental impact.
6. Which type of pesticide formulation is generally safer for aerial
application over rights-of-way?
A. Emulsifiable concentrates
B. Granules
C. Wettable powders
, D. Foggers
B. Granules
Rationale: Granules reduce drift and are less likely to contaminate
non-target areas during aerial application.
7. What is the primary concern when applying herbicides near power
lines?
A. Killing all plants in the area
B. Avoiding damage to the electrical infrastructure and preventing
human injury
C. Ensuring maximum herbicide coverage
D. Enhancing the aesthetic value of the corridor
B. Avoiding damage to the electrical infrastructure and preventing
human injury
Rationale: Safety is the top priority when working near high-voltage
power lines; herbicide selection and application must minimize risk.
8. Which piece of personal protective equipment (PPE) is always required
when mixing concentrated herbicides?
A. Safety glasses
B. Chemical-resistant gloves
C. Dust mask
D. Ear protection
B. Chemical-resistant gloves
