1. Who is responsible for ensuring pesticide applications within the Right
of Way are made in accordance with the label?
a) The landowner
b) The manufacturer
c) The certified applicator
d) The state agency
Certified applicators are legally responsible for proper pesticide use,
including label compliance.
2. What is the primary purpose of using herbicides in Right of Way
vegetation management?
a) To prevent wildlife intrusion
b) To maintain visibility and safety
c) To enhance biodiversity
d) To improve aesthetics
,Clear Right of Ways reduce fire hazards, maintain road safety, and ensure
access for maintenance.
3. What is the most critical factor to consider when selecting a herbicide
for use in a Right of Way?
a) Cost of the product
b) Site-specific vegetation and soil characteristics
c) Time of year
d) Size of the crew
Proper herbicide selection is based on plant species present and site
conditions like soil type and pH.
4. The label of a herbicide intended for ROW use must state:
a) It is safe for all plants
b) It is approved for non-crop areas
c) It has no residual effects
d) It can be applied without PPE
ROW herbicides must be labeled for use on non-crop sites or areas like
utility lines and roadsides.
5. What type of herbicide application would best control vegetation
under a powerline?
a) Broadcast spraying
b) Basal bark treatment
c) Injection
d) Aerial seeding
Basal bark treatments selectively target individual woody plants, ideal
under sensitive areas like powerlines.
6. Which of the following is considered a selective herbicide application?
, a) Blanket spray over entire Right of Way
b) Spot treatment of target weeds
c) Soil fumigation
d) Total vegetation control
Spot treatments target specific weeds, reducing non-target impact.
7. Drift is a major concern in ROW applications. How can drift be
minimized?
a) Apply during high wind
b) Use low-pressure, large droplet nozzles
c) Use aerial application only
d) Apply in the evening
Larger droplets at lower pressure reduce the chance of herbicide drift.
8. Which wind speed is generally acceptable for herbicide application in
Right of Way settings?
a) Over 15 mph
b) 3–10 mph
c) Less than 1 mph
d) Any wind speed
Wind between 3–10 mph allows for safe application without drift or
inversion risk.
9. A primary environmental concern with ROW herbicide use near
aquatic areas is:
a) Rodent control
b) Tree encroachment
c) Water contamination
d) Soil fertility
