Georgia Category 34 – Aerial Methods
Examination Questions And Correct
Answers (Verified Answers) Plus
Rationales
1. What is the primary purpose of aerial pesticide application?
A. To reduce labor costs only
B. To treat large or inaccessible areas efficiently
C. To eliminate the need for calibration
D. To prevent drift entirely
Answer: B
Rationale: Aerial application is primarily used to efficiently treat
large, remote, or difficult-to-access areas such as forests,
wetlands, and extensive agricultural fields. While it may reduce
labor costs, efficiency and coverage are the primary purposes.
Drift cannot be entirely eliminated.
,2. Which federal law regulates pesticide use in the United States?
A. Clean Air Act
B. Safe Drinking Water Act
C. Federal Insecticide, Fungicide, and Rodenticide Act
D. Occupational Safety and Health Act
Answer: C
Rationale: The Federal Insecticide, Fungicide, and Rodenticide
Act (FIFRA) governs pesticide registration, labeling, distribution,
sale, and use in the United States. Applicators must comply with
all label requirements under this law.
3. The pesticide label is considered:
A. A suggestion
B. Advisory guidance only
C. A legal document
D. Optional during aerial application
Answer: C
Rationale: The pesticide label is a legally enforceable document.
Applicators must follow all instructions and restrictions,
including application rates, buffer zones, and droplet size
requirements.
,4. Which droplet size classification reduces drift potential the most?
A. Fine
B. Very fine
C. Medium
D. Ultra-coarse
Answer: D
Rationale: Ultra-coarse droplets are heavier and less prone to
wind movement, reducing drift potential. However, excessively
large droplets may reduce coverage.
5. Temperature inversions most commonly occur:
A. At midday
B. On windy afternoons
C. In the early morning or evening under calm conditions
D. During heavy rainfall
Answer: C
Rationale: Temperature inversions typically form during calm,
clear conditions in early morning or evening when cooler air is
trapped near the ground, increasing drift risk.
6. The most effective way to minimize off-target drift is to:
A. Increase spray pressure
B. Use smaller droplets
, C. Spray during strong winds
D. Use larger droplets and monitor weather conditions
Answer: D
Rationale: Larger droplets are less prone to drift, and monitoring
wind speed, direction, and inversion conditions reduces off-
target movement.
7. What instrument is used to measure wind speed at the application
site?
A. Hygrometer
B. Anemometer
C. Barometer
D. Altimeter
Answer: B
Rationale: An anemometer measures wind speed, which is
critical in determining safe aerial spray conditions.
8. Swath width refers to:
A. Distance between aircraft and target
B. Width of treated area per pass
C. Length of the runway
D. Width of the aircraft wings
Answer: B
