1. When applying herbicides along a roadside right-of-way, what is the
primary purpose of using a surfactant with the pesticide mixture?
A. To increase the odor of the solution
B. To improve herbicide spread and uptake by plant foliage
C. To reduce the toxicity of the herbicide
D. To neutralize the active ingredient
Surfactants lower surface tension, allowing the herbicide spray to
spread evenly on and be absorbed by plant leaves, enhancing
effectiveness.
2. Which federal law regulates the labeling, sale, and use of pesticides in
the United States?
A. Clean Water Act
B. Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)
C. Endangered Species Act
D. Toxic Substances Control Act
FIFRA governs pesticide registration and use, requiring adherence to
label instructions and standards for safe application.
,3. What is the primary hazard associated with applying herbicides during
windy conditions?
A. Increased spray droplet size
B. Faster herbicide degradation
C. Off-target drift to non-target plants and areas
D. Reduced evaporation
Wind can carry fine droplets away from the target area, leading to
off-target damage and reduced control where needed.
4. A “right-of-way” pest control applicator is most likely to treat which of
the following?
A. Residential lawns
B. Retail garden centers
C. Vegetation along powerline corridors
D. Golf course greens
Right-of-way applicators focus on vegetation management along
utility corridors, roadways, and similar non-crop areas.
5. Which piece of personal protective equipment (PPE) is required when
handling concentrated herbicide formulations?
A. Cotton gloves
B. Chemical-resistant gloves
C. Safety vest
D. Steel-toe boots
Chemical-resistant gloves protect hands from harmful exposure to
concentrated pesticide formulations.
6. What does the signal word “DANGER” on a pesticide label indicate?
A. Lowest level of toxicity
B. Highest level of acute toxicity
C. Non-toxic product
D. Safe for general use
“DANGER” signifies the greatest acute hazard and requires strict
adherence to protective measures.
7. Which herbicide mode of action inhibits cell division in newly
emerging plant shoots?
A. Photosynthesis inhibitors
B. Root growth inhibitors
, C. Cell membrane disrupters
D. Microtubule assembly inhibitors
Microtubule assembly inhibitors prevent cell division in emerging
tissues, stopping shoot development.
8. What is the best management practice for preventing contamination
of water bodies during pesticide application?
A. Apply directly into water bodies
B. Establish buffer zones between application sites and water
sources
C. Increase spray pressure
D. Mix pesticides near water sources
Buffers help reduce the risk of pesticides entering water by runoff or
drift.
9. The term “pesticide resistant” refers to pest populations that:
A. Are susceptible to all pesticide treatments
B. Have developed the ability to survive pesticide exposure
C. Cannot be identified accurately
D. Die at low pesticide rates
Resistance means the pest can survive applications that once were
effective.
10. Which nutrient deficiency symptom is most likely to be confused
with herbicide damage in woody plants?
A. Chlorosis along leaf margins
B. Interveinal chlorosis
C. Uniform deep green foliage
D. New growth flush
Interveinal chlorosis can resemble herbicide injury but is often
nutrient related.
11. What should be done first if pesticide is spilled on the skin?
A. Wipe it off with a rag
B. Wait until the end of the day
C. Apply lotion
D. Immediately rinse with plenty of water
Prompt washing with water minimizes absorption and reduces
injury.
