distribution, sale, and use.
2. What is the primary purpose of a Right‐of‐Way pesticide application?
A. To increase ornamental plant growth
B. To control vegetation that interferes with utility, transportation, or
communication infrastructure
C. To improve soil quality
D. To enhance wildlife habitat
, Right‐of‐Way pesticide applications are intended to manage
vegetation that could compromise safety or service reliability along
infrastructure corridors.
3. Which of the following is considered a selective herbicide?
A. Glyphosate
B. 2,4‐D
C. Salt
D. Vinegar
2,4‐D selectively controls broadleaf weeds while having minimal
effect on grasses, distinguishing it as a selective herbicide.

A. The amount of time it takes to manufacture a pesticide
B. The length of time a pesticide remains active in the environment
C. The time needed to travel to an application site
D. The number of applications needed per season

detectable in the environment after application.
5. Which factor most influences spray drift during a pesticide
application?
A. Soil type
B. Wind speed and direction
C. Sunlight intensity
D. Time of day
Wind speed and direction are critical determinants of spray drift,
affecting where pesticide droplets travel after release.
6. What is the appropriate personal protective equipment (PPE) for
mixing concentrated herbicide formulations?

The REI is designed to prevent exposure to pesticide residues until
they diminish to safe levels.
9. Which of the following best describes integrated vegetation
management (IVM)?
A. Using only herbicides for vegetation control
B. A combination of chemical, mechanical, and biological methods to
manage vegetation
C. Planting ornamental flowers
D. Fertilization to promote plant growth
IVM emphasizes the use of multiple methods to achieve effective,
environmentally sound vegetation control.
