ASSURES PASS – PRACTICE ASSESSMENT
1. Which of the following best describes the mode of action of
organophosphate insecticides?
A. Disruption of chitin synthesis
B. Inhibition of acetylcholinesterase enzyme
C. Blockage of sodium channels in nerve cells
D. Interference with mitochondrial respiration
Rationale: Organophosphates inhibit acetylcholinesterase, leading to
accumulation of acetylcholine and overstimulation of nerves.
2. A pesticide label indicates "Use at 2 lbs per acre." You have a 50-acre field.
How much pesticide is required?
A. 50 lbs
B. 100 lbs
C. 25 lbs
D. 200 lbs
Rationale: 2 lbs/acre × 50 acres = 100 lbs total.
3. Which of the following is a key principle of integrated pest management
(IPM)?
A. Use only chemical controls to save time
B. Eradicate all pests regardless of threshold
, C. Employ multiple control strategies based on pest monitoring
D. Spray preventively without pest identification
Rationale: IPM emphasizes monitoring, thresholds, and a combination of
cultural, biological, and chemical controls.
4. A pesticide applicator notices a spill of a liquid herbicide. What is the first
immediate action?
A. Continue applying to prevent waste
B. Sweep up the chemical and dispose in trash
C. Isolate the area and follow emergency procedures on the SDS
D. Rinse the area with water
Rationale: Safety protocols require isolating the spill area and consulting the
Safety Data Sheet (SDS) for proper cleanup.
5. Which factor most affects pesticide absorption through the skin?
A. Wind speed
B. Soil pH
C. Solvent type and concentration
D. Crop growth stage
Rationale: Solvent type and concentration influence dermal absorption of
chemicals.
6. The most effective way to reduce drift during aerial pesticide application is:
A. Use a higher boom height
B. Apply during low wind and at proper droplet size
, C. Increase nozzle pressure
D. Spray in early morning fog
Rationale: Drift reduction depends on droplet size, wind conditions, and proper
application technique.
7. Which of the following is a restricted-use pesticide (RUP)?
A. Bacillus thuringiensis (Bt)
B. Chlorpyrifos
C. Neem oil
D. Pyrethrin
Rationale: Chlorpyrifos is classified as a restricted-use pesticide due to toxicity
and environmental concerns.
8. When applying pesticides near a water body, which action is MOST critical?
A. Spray faster to minimize time
B. Apply at night to avoid evaporation
C. Use higher pressure nozzles to reach farther
D. Maintain buffer zones and avoid direct drift into water
Rationale: Regulatory standards require buffer zones to protect aquatic
ecosystems.
9. Which personal protective equipment (PPE) is required when mixing
concentrated pesticides?
A. Safety glasses only
B. Cotton gloves and cap
, C. Chemical-resistant gloves, apron, and respirator
D. Long-sleeve shirt
Rationale: High exposure during mixing requires chemical-resistant PPE to
prevent dermal and inhalation exposure.
10. A worker develops mild pesticide symptoms: headache and dizziness.
Immediate first aid should include:
A. Induce vomiting
B. Apply ointment
C. Move to fresh air and seek medical attention
D. Drink water and continue work
Rationale: Removing the worker from exposure and seeking medical evaluation
is the safest response.
11. Which factor determines pesticide persistence in soil?
A. Soil color
B. Organic matter content and microbial activity
C. Crop type
D. Time of day
Rationale: High organic content and microbial degradation influence pesticide
half-life in soil.
12. Which law governs pesticide registration, labeling, and safe use in the U.S.?
A. Clean Water Act
B. Endangered Species Act
