1. Which is the primary objective of right-of-way pest control?
A. To eliminate all vegetation permanently
B. To maintain vegetation-free soil at all times
C. To manage vegetation that interferes with infrastructure safety
and access
D. To encourage maximum biodiversity along corridors
Correct vegetation management in right-of-way pest control focuses
on controlling plant growth that obstructs visibility, damages
infrastructure, or interferes with utility operations while maintaining
safety and environmental compliance.
2. Which herbicide type is most commonly used for total vegetation
control in non-crop right-of-way areas?
A. Selective herbicides
B. Pre-emergent fertilizers
C. Non-selective systemic herbicides
D. Growth stimulants
Non-selective systemic herbicides kill most or all vegetation and are
, widely used in areas where complete vegetation control is required,
such as railways and utility corridors.
3. What is the main risk associated with herbicide drift?
A. Increased weed resistance
B. Soil erosion reduction
C. Damage to non-target vegetation and environmental
contamination
D. Improved herbicide effectiveness
Herbicide drift can move chemicals off-target, potentially damaging
crops, ornamental plants, and sensitive ecosystems.
4. What is the purpose of a surfactant in herbicide application?
A. To neutralize herbicide toxicity
B. To increase soil absorption
C. To improve spreading and absorption on plant surfaces
D. To increase herbicide volatility
Surfactants help herbicides spread evenly and penetrate plant
surfaces more effectively, improving control efficiency.
5. Which factor most influences herbicide effectiveness?
A. Container color
B. Operator clothing
C. Plant growth stage and environmental conditions
D. Application vehicle brand
Herbicide performance is strongly affected by plant maturity,
temperature, humidity, and moisture conditions.
6. Which PPE is most essential when handling concentrated herbicides?
A. Sunglasses
B. Leather boots only
C. Chemical-resistant gloves and protective eyewear
D. Cotton shirt
, Proper PPE such as gloves and goggles prevents exposure to
hazardous chemicals during mixing and application.
7. What is a key characteristic of systemic herbicides?
A. They only burn leaf surfaces
B. They remain on plant surfaces
C. They are absorbed and translocated throughout the plant
D. They only affect soil microorganisms
Systemic herbicides move within the plant’s vascular system, killing
roots and shoots for long-term control.
8. Why is calibration of application equipment important?
A. To increase spray color visibility
B. To reduce operator fatigue
C. To ensure correct herbicide dosage is applied
D. To prevent equipment rust
Calibration ensures the correct amount of herbicide is applied,
preventing under-dosing or over-application.
9. Which condition increases the risk of herbicide volatilization?
A. Low temperature
B. High soil moisture
C. High temperature and wind
D. Cloudy weather
High temperatures can cause certain herbicides to vaporize and move
off-target.
10. What is the primary purpose of vegetation management along
roadsides?
A. Increase aesthetic floral diversity
B. Prevent soil formation
C. Maintain driver visibility and road safety
D. Eliminate all insects
