1. What is the primary purpose of aerial pesticide application?
A. Increase pesticide toxicity
B. Deliver pesticides efficiently over large or inaccessible areas
C. Eliminate need for pesticide labels
D. Replace all ground applications
Correct Answer: B
Rationale: Aerial application is used to efficiently treat large or
difficult terrain areas that ground equipment cannot easily access.
2. Which factor most directly affects spray drift?
A. Tank color
B. Wind speed
C. Pilot age
, D. Pesticide brand
Correct Answer: B
Rationale: Wind speed is a major determinant of how far spray
droplets move away from the target area.
3. What droplet size is generally preferred to reduce drift?
A. Very fine
B. Fine mist only
C. Coarse droplets
D. Vapor-sized droplets
Correct Answer: C
Rationale: Coarser droplets are heavier and less likely to drift off-
target.
4. What weather condition increases inversion risk?
A. Strong wind
B. Stable air with little vertical mixing
C. Heavy rain
D. High turbulence
Correct Answer: B
Rationale: Temperature inversions trap air near the ground,
increasing drift potential.
5. What is a swath in aerial application?
A. Fuel load area
B. Width of treated area per pass
, C. Pilot flight path
D. Mixing zone
Correct Answer: B
Rationale: A swath is the width of the spray pattern deposited in one
pass.
6. Which device is commonly used to improve aerial application
accuracy?
A. Barometer
B. GPS guidance system
C. Compass only
D. Thermometer
Correct Answer: B
Rationale: GPS helps ensure accurate flight paths and application
coverage.
7. What is the main purpose of adjuvants?
A. Replace pesticides
B. Improve pesticide performance
C. Neutralize labels
D. Increase drift
Correct Answer: B
Rationale: Adjuvants enhance mixing, spreading, or sticking of
pesticides.
, 8. What is the safest action before loading pesticide into an aircraft?
A. Start engine
B. Read the label
C. Increase throttle
D. Fly test pattern
Correct Answer: B
Rationale: The label provides legal and safety instructions for
handling.
9. What does PPE stand for?
A. Personal Pest Equipment
B. Protective Pesticide Engine
C. Personal Protective Equipment
D. Professional Pest Evaluation
Correct Answer: C
Rationale: PPE refers to protective clothing and gear to reduce
exposure.
10. What is a major hazard during aerial mixing/loading?
A. Noise only
B. Chemical exposure
C. GPS error
D. Fuel freezing
Correct Answer: B
